本文实例为大家分享了Android实现闪屏页效果的具体代码，供大家参考，具体内容如下

1.效果图

2.闪屏页逻辑及布局

2.1 activity_splash.xml


<?xml version="1.0" encoding="utf-8"?>
<FrameLayout 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">
 <ImageView
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:src="@drawable/splash"
  android:scaleType="centerCrop"/>
 <Button
  android:id="@+id/splash_btn_skip"
  android:layout_width="45dp"
  android:layout_height="32dp"
  android:text="跳过"
  android:textStyle="bold"
  android:textColor="#fff"
  android:background="#30000000"
  android:layout_gravity="right"
  android:layout_marginTop="30dp"
  android:layout_marginRight="30dp"/>
</FrameLayout>

2.2 SplashActivity.java

通过Handler实现


public class SplashActivity extends AppCompatActivity {
 //跳过按钮
 private Button btnSkip;
 private Handler handler = new Handler();
 private Runnable runnableToLogin = new Runnable() {
  @Override
  public void run() {
   toLoginActivity();
  }
 };
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_splash);
  initView();
  initEvent();
  //延迟4秒
  handler.postDelayed(runnableToLogin,4000);
 }
 //初始化组件
 public void initView(){
  btnSkip = findViewById(R.id.splash_btn_skip);
 }
 //监听事件
 public void initEvent(){
  btnSkip.setOnClickListener(new View.OnClickListener() {
   @Override
   public void onClick(View v) {
    //防止LoginActivity被打开两次
    handler.removeCallbacks(runnableToLogin);
    toLoginActivity();
   }
  });
 }
 /**
  * 跳转到登录界面
  */
 private void toLoginActivity(){
  Intent intent = new Intent(this,LoginActivity.class);
  startActivity(intent);
  finish();
 }
 @Override
 protected void onDestroy() {
  super.onDestroy();
  //防止内存泄漏
  handler.removeCallbacks(runnableToLogin);
 }
}

3.设置主题样式

3.1 style.xml中


<resources>
 <!-- Base application theme. -->
 <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
  <!-- Customize your theme here. -->
  <item name="colorPrimary">@color/colorPrimary</item>
  <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
  <item name="colorAccent">@color/colorAccent</item>
 </style>
 <style name="AppTheme_FullScreen" parent="AppTheme">
  <item name="android:windowFullscreen">true</item>
 </style>
</resources>

3.2 AndroidManifest.xml中


<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
 package="com.example.myrestaurant">
 <uses-permission android:name="android.permission.INTERNET" />
 <application
  android:allowBackup="true"
  android:icon="@mipmap/ic_launcher"
  android:label="@string/app_name"
  android:roundIcon="@mipmap/ic_launcher_round"
  android:supportsRtl="true"
  android:theme="@style/AppTheme">
  <activity android:name=".LoginActivity"></activity>
  <activity android:name=".SplashActivity"
   android:theme="@style/AppTheme_FullScreen">
   <intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
   </intent-filter>
  </activity>
 </application>
</manifest>
