效果演示

随手做的一个小玩意，还有很多功能没有完善，倘有疏漏，万望海涵。

实现功能总览

实现了登录、注册、忘记密码、成绩查询、考勤情况、课表查看、提交作业、课程打卡等。

代码 登录与忘记密码界面

登录与忘记密码界面采用的是TabLayout+ViewPager+PagerAdapter实现的

一、添加布局文件


 View View_HomePager = LayoutInflater.from( Student.this ).inflate( R.layout.homeppage_item,null,false );
 View View_Data = LayoutInflater.from( Student.this ).inflate( R.layout.data_item,null,false );
 View View_Course = LayoutInflater.from( Student.this ).inflate( R.layout.course_item,null,false );
 View View_My = LayoutInflater.from( Student.this ).inflate( R.layout.my_item,null,false );


private List<View> Views = new ArrayList<>(  );


 Views.add( View_HomePager );
 Views.add( View_Data );
 Views.add( View_Course );
 Views.add( View_My );

二、添加标题文字


private List<String> Titles = new ArrayList<>(  );


Titles.add( "首页" );
Titles.add( "数据" );
Titles.add( "课程" );
Titles.add( "我的" );

三、绑定适配器


/*PagerAdapter 适配器代码如下*/
public class ViewPagerAdapter extends PagerAdapter {
    private List<View> Views;
    private List<String> Titles;
    public ViewPagerAdapter(List<View> Views,List<String> Titles){
        this.Views = Views;
        this.Titles = Titles;
    }
    @Override
    public int getCount() {
        return Views.size();
    }
    @Override
    public boolean isViewFromObject(@NonNull View view, @NonNull Object object) {
        return view == object;
    }
    @NonNull
    @Override
    public Object instantiateItem(@NonNull ViewGroup container, int position) {
        container.addView( Views.get( position ) );
        return Views.get( position );
    }
    @Override
    public void destroyItem(@NonNull ViewGroup container, int position, @NonNull Object object) {
        container.removeView( Views.get( position ) );
    }
    @Nullable
    @Override
    public CharSequence getPageTitle(int position) {
        return Titles.get( position );
    }
}


 ViewPagerAdapter adapter = new ViewPagerAdapter( Views,Titles );
        for (String title : Titles){
            Title.addTab( Title.newTab().setText( title ) );
        }
        Title.setupWithViewPager( viewPager );
        viewPager.setAdapter( adapter );

注册界面
一、创建两个Drawable文件

其一


<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval">
<solid android:color="#63B8FF"/>
    <size android:width="20dp" android:height="20dp"/>
</shape>

其二


<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval">
    <solid android:color="#ffffff"/>
    <size android:height="20dp" android:width="20dp"/>
    <stroke android:width="1dp" android:color="#EAEAEA"/>
</shape>

二、将其添加数组内


private final int[] Identity = {R.drawable.press_oval_textview,R.drawable.notpress_oval_textview};

三、动态变化背景


 private void SelectStudent(){
        mIdentity_Student.setBackgroundResource( Identity[0] );
        mIdentity_Teacher.setBackgroundResource( Identity[1] );
    }
    private void SelectTeacher(){
        mIdentity_Student.setBackgroundResource( Identity[1] );
        mIdentity_Teacher.setBackgroundResource( Identity[0] );
    }

考勤界面

主要是通过绘制一个圆，圆环、内圆、文字分别使用不同的背景颜色，并将修改背景颜色的接口暴露出来。

一、CircleProgressBar代码如下


public class CircleProgressBar extends View {
    // 画实心圆的画笔
    private Paint mCirclePaint;
    // 画圆环的画笔
    private Paint mRingPaint;
    // 画圆环的画笔背景色
    private Paint mRingPaintBg;
    // 画字体的画笔
    private Paint mTextPaint;
    // 圆形颜色
    private int mCircleColor;
    // 圆环颜色
    private int mRingColor;
    // 圆环背景颜色
    private int mRingBgColor;
    // 半径
    private float mRadius;
    // 圆环半径
    private float mRingRadius;
    // 圆环宽度
    private float mStrokeWidth;
    // 圆心x坐标
    private int mXCenter;
    // 圆心y坐标
    private int mYCenter;
    // 字的长度
    private float mTxtWidth;
    // 字的高度
    private float mTxtHeight;
    // 总进度
    private int mTotalProgress = 100;
    // 当前进度
    private double mProgress;
    public CircleProgressBar(Context context) {
        super( context );
    }
    public CircleProgressBar(Context context, @Nullable AttributeSet attrs) {
        super( context, attrs );
        initAttrs(context,attrs);
        initVariable();
    }
    public CircleProgressBar(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
        super( context, attrs, defStyleAttr );
    }
    private void initAttrs(Context context, AttributeSet attrs) {
        TypedArray typeArray = context.getTheme().obtainStyledAttributes(attrs,
                R.styleable.TasksCompletedView, 0, 0);
        mRadius = typeArray.getDimension(R.styleable.TasksCompletedView_radius, 80);
        mStrokeWidth = typeArray.getDimension(R.styleable.TasksCompletedView_strokeWidth, 10);
        mCircleColor = typeArray.getColor(R.styleable.TasksCompletedView_circleColor, 0xFFFFFFFF);
        mRingColor = typeArray.getColor(R.styleable.TasksCompletedView_ringColor, 0xFFFFFFFF);
        mRingBgColor = typeArray.getColor(R.styleable.TasksCompletedView_ringBgColor, 0xFFFFFFFF);
        mRingRadius = mRadius + mStrokeWidth / 2;
    }
    private void initVariable() {
        //内圆
        mCirclePaint = new Paint();
        mCirclePaint.setAntiAlias(true);
        mCirclePaint.setColor(mCircleColor);
        mCirclePaint.setStyle(Paint.Style.FILL);
        //外圆弧背景
        mRingPaintBg = new Paint();
        mRingPaintBg.setAntiAlias(true);
        mRingPaintBg.setColor(mRingBgColor);
        mRingPaintBg.setStyle(Paint.Style.STROKE);
        mRingPaintBg.setStrokeWidth(mStrokeWidth);
        //外圆弧
        mRingPaint = new Paint();
        mRingPaint.setAntiAlias(true);
        mRingPaint.setColor(mRingColor);
        mRingPaint.setStyle(Paint.Style.STROKE);
        mRingPaint.setStrokeWidth(mStrokeWidth);
        //mRingPaint.setStrokeCap(Paint.Cap.ROUND);//设置线冒样式，有圆 有方
        //中间字
        mTextPaint = new Paint();
        mTextPaint.setAntiAlias(true);
        mTextPaint.setStyle(Paint.Style.FILL);
        mTextPaint.setColor(mRingColor);
        mTextPaint.setTextSize(mRadius / 2);
        Paint.FontMetrics fm = mTextPaint.getFontMetrics();
        mTxtHeight = (int) Math.ceil(fm.descent - fm.ascent);
    }
    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw( canvas );
        mXCenter = getWidth() / 2;
        mYCenter = getHeight() / 2;
        //内圆
        canvas.drawCircle( mXCenter, mYCenter, mRadius, mCirclePaint );
        //外圆弧背景
        RectF oval1 = new RectF();
        oval1.left = (mXCenter - mRingRadius);
        oval1.top = (mYCenter - mRingRadius);
        oval1.right = mRingRadius * 2 + (mXCenter - mRingRadius);
        oval1.bottom = mRingRadius * 2 + (mYCenter - mRingRadius);
        canvas.drawArc( oval1, 0, 360, false, mRingPaintBg ); //圆弧所在的椭圆对象、圆弧的起始角度、圆弧的角度、是否显示半径连线
        //外圆弧
        if (mProgress > 0) {
            RectF oval = new RectF();
            oval.left = (mXCenter - mRingRadius);
            oval.top = (mYCenter - mRingRadius);
            oval.right = mRingRadius * 2 + (mXCenter - mRingRadius);
            oval.bottom = mRingRadius * 2 + (mYCenter - mRingRadius);
            canvas.drawArc( oval, -90, ((float) mProgress / mTotalProgress) * 360, false, mRingPaint ); //
            //字体
            String txt = mProgress + "%";
            mTxtWidth = mTextPaint.measureText( txt, 0, txt.length() );
            canvas.drawText( txt, mXCenter - mTxtWidth / 2, mYCenter + mTxtHeight / 4, mTextPaint );
        }
    }
    //设置进度
    public void setProgress(double progress) {
        mProgress = progress;
        postInvalidate();//重绘
    }
    public void setCircleColor(int Color){
        mRingPaint.setColor( Color );
        postInvalidate();//重绘
    }
}

签到界面

签到界面就倒计时和位置签到

一、倒计时

采用的是Thread+Handler
在子线程内总共发生两种标志至Handler内，0x00表示倒计时未完成，0x01表示倒计时完成。


private void CountDown(){
        new Thread(  ){
            @Override
            public void run() {
                super.run();
                for (int j = 14; j >= 0 ; j--) {
                    for (int i = 59; i >= 0; i--) {
                        Message message = handler.obtainMessage();
                        message.what = 0x00;
                        message.arg1 = i;
                        message.arg2 = j;
                        handler.sendMessage( message );
                        try {
                            Thread.sleep( 1000 );
                        } catch (InterruptedException e) {
                            e.printStackTrace();
                        }
                    }
                }
                Message message = handler.obtainMessage(  );
                message.what = 0x01;
                handler.sendMessage( message );
            }
        }.start();
    }


 final Handler handler = new Handler(  ){
        @Override
        public void handleMessage(@NonNull Message msg) {
            super.handleMessage( msg );
            switch (msg.what){
                case 0x00:
                    if (msg.arg2 >= 10){
                        SignInMinutes.setText( msg.arg2+":" );
                }else if (msg.arg2 < 10 && msg.arg2 > 0){
                        SignInMinutes.setText( "0"+msg.arg2+":" );
                }else {
                        SignInMinutes.setText( "00"+":" );
                }
                    if (msg.arg1 >= 10){
                        SignInSeconds.setText( msg.arg1+"" );
                    }else if (msg.arg1 < 10 && msg.arg1 > 0){
                        SignInSeconds.setText( "0"+msg.arg1 );
                    }else {
                        SignInSeconds.setText( "00" );
                    }
                    break;
                case 0x01:
                    SignInSeconds.setText( "00" );
                    SignInMinutes.setText( "00:" );
                    break;
            }
        }
    };

二、位置签到

位置签到采用的是百度地图SDK


public class LocationCheckIn extends AppCompatActivity {
    private MapView BaiDuMapView;
    private TextView CurrentPosition,mLatitude,mLongitude,CurrentDate,SignInPosition;
    private Button SubmitMessage,SuccessSignIn;
    private ImageView LocationSignIn_Exit;
    private  View view = null;
    private PopupWindow mPopupWindow;
    private LocationClient client;
    private BaiduMap mBaiduMap;
    private double Latitude = 0;
    private double Longitude = 0;
    private boolean isFirstLocate = true;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate( savedInstanceState );
        if (Build.VERSION.SDK_INT >= 21) {
            View decorView = getWindow().getDecorView();
            decorView.setSystemUiVisibility( View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_STABLE );
            getWindow().setStatusBarColor( Color.TRANSPARENT );
        }
        SDKInitializer.initialize( getApplicationContext() );
        client = new LocationClient( getApplicationContext() );//获取全局Context
        client.registerLocationListener( new MyBaiDuMap() );//注册一个定位监听器，获取位置信息，回调此定位监听器
        setContentView( R.layout.activity_location_check_in );
        InitView();
        InitBaiDuMap();
        InitPermission();
        InitPopWindows();
        Listener();
    }
    private void InitView(){
        BaiDuMapView = findViewById( R.id.BaiDu_MapView );
        CurrentPosition = findViewById( R.id.CurrentPosition );
        SubmitMessage = findViewById( R.id.SubmitMessage );
        mLatitude = findViewById( R.id.Latitude );
        mLongitude = findViewById( R.id.Longitude );
        LocationSignIn_Exit = findViewById( R.id.LocationSignIn_Exit );
    }
    private void InitPopWindows(){
         view = LayoutInflater.from( LocationCheckIn.this ).inflate( R.layout.signin_success ,null,false);
        CurrentDate = view.findViewById( R.id.CurrentDate );
        SignInPosition = view.findViewById( R.id.SignInPosition );
        SuccessSignIn = view.findViewById( R.id.Success);
        mPopupWindow = new PopupWindow( view, ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.WRAP_CONTENT );
        mPopupWindow.setFocusable( true ); //获取焦点
        mPopupWindow.setBackgroundDrawable( new BitmapDrawable() );
        mPopupWindow.setOutsideTouchable( true ); //点击外面地方，取消
        mPopupWindow.setTouchable( true ); //允许点击
        mPopupWindow.setAnimationStyle( R.style.MyPopupWindow ); //设置动画
        Calendar calendar = Calendar.getInstance();
        int Hour = calendar.get( Calendar.HOUR_OF_DAY );
        int Minute = calendar.get( Calendar.MINUTE );
        String sHour,sMinute;
        if (Hour < 10){
            sHour = "0"+Hour;
        }else {
            sHour = ""+Hour;
        }

        }
        CurrentDate.setText( sHour+":"+sMinute );
        //SignInPosition.setText( Position+"000");
        SuccessSignIn.setOnClickListener( new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mPopupWindow.dismiss();
            }

    }
    private void InitBaiDuMap(){
        /*百度地图初始化*/
        mBaiduMap = BaiDuMapView.getMap();//获取实例，可以对地图进行一系列操作，比如：缩放范围，移动地图

成绩查询界面

采用的是MD的CardStackView，需要实现一个Adapter适配器，此适配器与RecyclerView适配器构建类似

一、创建StackAdapter 适配器


package com.franzliszt.Student.QueryScore;
public class StackAdapter extends com.loopeer.cardstack.StackAdapter<Integer> {
    public StackAdapter(Context context) {
        super(context);
    }
    @Override
    public void bindView(Integer data, int position, CardStackView.ViewHolder holder) {
        if (holder instanceof ColorItemLargeHeaderViewHolder) {
            ColorItemLargeHeaderViewHolder h = (ColorItemLargeHeaderViewHolder) holder;
            h.onBind(data, position);
        }
        if (holder instanceof ColorItemWithNoHeaderViewHolder) {
            ColorItemWithNoHeaderViewHolder h = (ColorItemWithNoHeaderViewHolder) holder;
            h.onBind(data, position);
        }
        if (holder instanceof ColorItemViewHolder) {
            ColorItemViewHolder h = (ColorItemViewHolder) holder;
            h.onBind(data, position);
        }
    }
    @Override
    protected CardStackView.ViewHolder onCreateView(ViewGroup parent, int viewType) {
        View view;
        switch (viewType) {
            case R.layout.list_card_item_larger_header:
                view = getLayoutInflater().inflate(R.layout.list_card_item_larger_header, parent, false);
                return new ColorItemLargeHeaderViewHolder(view);
            case R.layout.list_card_item_with_no_header:
                view = getLayoutInflater().inflate(R.layout.list_card_item_with_no_header, parent, false);
                return new ColorItemWithNoHeaderViewHolder(view);
            case R.layout.other_item:
                view = getLayoutInflater().inflate(R.layout.other_item, parent, false);
                return new ColorItemViewHolder(view);
            case R.layout.other_item_thank:

                view = getLayoutInflater().inflate(R.layout.other_item_note_2, parent, false);
                return new ColorItemViewHolder(view);
            default:
                view = getLayoutInflater().inflate(R.layout.first_semester, parent, false);
                return new ColorItemViewHolder(view);

            }else if (position == 6){
                mTextTitle.setText( "毕业设计");
            }else if (position == 7){
                mTextTitle.setText( "致谢");

    static class ColorItemWithNoHeaderViewHolder extends CardStackView.ViewHolder {
        View mLayout;
        TextView mTextTitle;
        public ColorItemWithNoHeaderViewHolder(View view) {
            super(view);
            mLayout = view.findViewById(R.id.frame_list_card_item);
            mTextTitle = (TextView) view.findViewById(R.id.text_list_card_title);
        }
        @Override
        public void onItemExpand(boolean b) {
        }
        public void onBind(Integer data, int position) {
            mLayout.getBackground().setColorFilter(ContextCompat.getColor(getContext(), data), PorterDuff.Mode.SRC_IN);
            mTextTitle.setText( String.valueOf(position));
        }
    }
    static class ColorItemLargeHeaderViewHolder extends CardStackView.ViewHolder {
        View mLayout;
        View mContainerContent;
        TextView mTextTitle;
        public ColorItemLargeHeaderViewHolder(View view) {
            super(view);
            mLayout = view.findViewById(R.id.frame_list_card_item);
            mContainerContent = view.findViewById(R.id.container_list_content);
            mTextTitle = view.findViewById(R.id.text_list_card_title);
        }
        @Override
        public void onItemExpand(boolean b) {
            mContainerContent.setVisibility(b ? View.VISIBLE : View.GONE);
        }
        @Override
        protected void onAnimationStateChange(int state, boolean willBeSelect) {
            super.onAnimationStateChange(state, willBeSelect);
            if (state == CardStackView.ANIMATION_STATE_START && willBeSelect) {
                onItemExpand(true);
            }
            if (state == CardStackView.ANIMATION_STATE_END && !willBeSelect) {
                onItemExpand(false);
            }
        }
        public void onBind(Integer data, int position) {
            mLayout.getBackground().setColorFilter(ContextCompat.getColor(getContext(), data), PorterDuff.Mode.SRC_IN);
            mTextTitle.setText( String.valueOf(position));
            mTextTitle.setText( "2019-2020第一学期");
            itemView.findViewById(R.id.text_view).setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    ((CardStackView)itemView.getParent()).performItemClick(ColorItemLargeHeaderViewHolder.this);
                }
            });
        }
    }
}

二、绑定适配器


 QueryScoreCardStackView.setItemExpendListener( this );
        adapter = new StackAdapter( this );
        QueryScoreCardStackView.setAdapter( adapter );

三、为每一个子项添加背景色


    public static Integer[] COLOR_DATAS = new Integer[]{
            R.color.color_1,
            R.color.color_2,
            R.color.color_3,
            R.color.color_4,
            R.color.color_5,
            R.color.color_6,
            R.color.color_7,
            R.color.color_8,
            R.color.color_9,
            R.color.color_10,
    };


 new Handler(  ).postDelayed( new Runnable() {
            @Override
            public void run() {
                adapter.updateData( Arrays.asList( COLOR_DATAS ) );
            }
        } ,200);
