Android实现闪屏页效果

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>
