AndroidStudio实现微信界面设计
目录
一、内容
二、技术
三、xml代码
四、Java代码
五、界面展示
一、内容实操实现APP门户界面框架设计，至少包含4个tab页，能实现tab页之间的点击切换
二、技术使用布局（layouts）和分段（fragment），对控件进行点击监听
三、xml代码top.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="55dp"
android:background="@color/black">
<TextView
android:id="@+id/textView5"
android:layout_width="wrap_content"
android:layout_height="55dp"
android:layout_weight="1"
android:gravity="center"
android:text="应用"
android:textColor="@color/white"
android:textSize="30sp" />
</LinearLayout>
界面居中上方写标题，背景是黑色，字体是白色
bottom.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="100dp"
android:background="@color/black"
>
<LinearLayout

android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:orientation="vertical">
<ImageView
android:id="@+id/imageView2"
android:layout_width="30dp"
android:layout_height="30dp"

/>
<TextView

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"

android:layout_height="wrap_content"
android:gravity="center"
android:text="我"

android:textSize="24sp" />
</LinearLayout>
</LinearLayout>
界面下方分成四个模板，由图片和文字组成，正在使用的界面图标为绿色，不在使用的界面图标为黑色
fragment_config.xml/fragment_wechat/fragment_friend/fragment_contact
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".Fragment_config">
<!-- TODO: Update blank fragment layout -->
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:text="这是微信聊天界面"
android:textSize="35sp" />
</LinearLayout>
显示界面中间内容
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity">
<include
layout="@layout/top"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<FrameLayout
android:id="@+id/id_content"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1">
</FrameLayout>
<include
layout="@layout/bottom"
android:gravity="bottom" />
</LinearLayout>
将top.xml和bottom.xml放在一个界面中
MainActivity.java
package com.example.cyxapp;
import androidx.appcompat.app.AppCompatActivity;
import android.app.Fragment;
import android.app.FragmentManager;
import android.app.FragmentTransaction;
import android.graphics.Color;
import android.os.Bundle;
import android.view.View;
import android.widget.LinearLayout;
public class MainActivity extends AppCompatActivity implements View.OnClickListener{
private Fragment Fragment_config=new Fragment_config();
private Fragment Fragment_contact=new Fragment_contact();
private Fragment Fragment_wechat=new Fragment_wechat();
private Fragment Fragment_friend=new Fragment_friend();
private FragmentManager fragmentManager;
private LinearLayout linearLayout1,linearLayout2,linearLayout3,linearLayout4;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
linearLayout1=findViewById(R.id.linearLayout1);
linearLayout2=findViewById(R.id.linearLayout2);
linearLayout3=findViewById(R.id.linearLayout3);
linearLayout4=findViewById(R.id.linearLayout4);
linearLayout1.setOnClickListener(this);
linearLayout2.setOnClickListener(this);
linearLayout3.setOnClickListener(this);
linearLayout4.setOnClickListener(this);
initFragment();
}
private void initFragment(){
fragmentManager=getFragmentManager();
FragmentTransaction transaction=fragmentManager.beginTransaction();
transaction.add(R.id.id_content,Fragment_wechat);
transaction.add(R.id.id_content,Fragment_contact);
transaction.add(R.id.id_content,Fragment_config);
transaction.add(R.id.id_content,Fragment_friend);
transaction.commit();
}
private void hideFragment(FragmentTransaction transaction){
transaction.hide(Fragment_wechat);
transaction.hide(Fragment_contact);
transaction.hide(Fragment_config);
transaction.hide(Fragment_friend);
}
private void background(View v) {
switch (v.getId()) {
case R.id.linearLayout1:
linearLayout1.setBackgroundColor(Color.parseColor("#426F42"));
break;
case R.id.linearLayout2:
linearLayout2.setBackgroundColor(Color.parseColor("#426F42"));
break;
case R.id.linearLayout3:
linearLayout3.setBackgroundColor(Color.parseColor("#426F42"));
break;
case R.id.linearLayout4:
linearLayout4.setBackgroundColor(Color.parseColor("#426F42"));
break;
default:
break;
}
}
private void backgroundreturn(View v) {
switch (v.getId()) {
case R.id.linearLayout1:
linearLayout1.setBackgroundColor(Color.parseColor("#000000"));
break;
case R.id.linearLayout2:
linearLayout2.setBackgroundColor(Color.parseColor("#000000"));
break;
case R.id.linearLayout3:
linearLayout3.setBackgroundColor(Color.parseColor("#000000"));
break;
case R.id.linearLayout4:
linearLayout4.setBackgroundColor(Color.parseColor("#000000"));
break;
default:
break;
}
}
private void showfragmnet(int i) {
FragmentTransaction transaction=fragmentManager.beginTransaction();
hideFragment(transaction);
switch (i){
case 0:
transaction.show(Fragment_wechat);
background(linearLayout1);
backgroundreturn(linearLayout3);
backgroundreturn(linearLayout2);
backgroundreturn(linearLayout4);
break;
case 1:
transaction.show(Fragment_friend);
background(linearLayout2);
backgroundreturn(linearLayout4);
backgroundreturn(linearLayout1);
backgroundreturn(linearLayout3);
break;
case 2:
transaction.show(Fragment_contact);
background(linearLayout3);
backgroundreturn(linearLayout4);
backgroundreturn(linearLayout2);
backgroundreturn(linearLayout1);
break;
case 3:
transaction.show(Fragment_config);
background(linearLayout4);
backgroundreturn(linearLayout1);
backgroundreturn(linearLayout2);
backgroundreturn(linearLayout3);
break;
default:
break;
}
transaction.commit();
}
@Override
public void onClick(View v) {
switch (v.getId()){
case R.id.linearLayout1:
showfragmnet(0);
break;
case R.id.linearLayout2:
showfragmnet(1);
break;
case R.id.linearLayout3:
showfragmnet(2);
break;
case R.id.linearLayout4:
showfragmnet(3);
break;
default:
break;
}
}
}
initFragment函数中利用transaction来实现fragment的切换
hideFragment把没有使用的界面的fragment的内容隐藏起来
background使图标点击后变绿色
backgroundreturn让图标恢复黑色
showfragmnet显示正在使用界面的fragment的内容
onClick监听函数，监听到底是哪一个图标被击中从而显示哪一个界面的内容
Fragment_config.java
package com.example.cyxapp;
import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class Fragment_config extends Fragment {
public Fragment_config() {
// Required empty public constructor
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_config, container, false);
}
}
Fragment_contact、Fragment_friend、Fragment_wechat类似
五、界面展示
