我实现了一个闪屏我的主要活动前推出。在我把开机画面，它的工作。我不知道我要去的地方错了还是什么我错过了。

这是我的代码

Splashscreen.java : 
 

 
    package pens.pensnews;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.os.Handler;import android.view.Window;import android.view.WindowManager; 
 
    public class Splashscreen extends Activity { 
 

 
    //Set waktu lama splashscreen 
 
    private static int splashInterval = 2000; 
 
    @Override 
 
    protected void onCreate(Bundle savedInstanceState) { 
 
     super.onCreate(savedInstanceState); 
 
     this.requestWindowFeature(Window.FEATURE_NO_TITLE); 
 
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
 
       WindowManager.LayoutParams.FLAG_FULLSCREEN); 
 
     setContentView(R.layout.activity_splashscreen); 
 
    new Handler().postDelayed(new Runnable(){ 
 
      @Override 
 
      public void run() { 
 
       // TODO Auto-generated method stub 
 
    Intent i = new Intent(getApplicationContext(), MainActivity.class); 
 
       startActivity(i); // menghubungkan activity splashscreen ke main activity dengan intent 
 

 
       //jeda selesai Splashscreen

      } 
 
     }, splashInterval); 
 
    }}

答

加入这行的AndroidManifest.xml

机器人：主题= “@风格/ AppTheme.NoActionBar”

AF之三加入这一行你的文件看起来像这样..

<activity 
      android:name="pens.pensnews.Splashscreen" 
    android:label="@string/app_name" 
      android:theme="@style/Splashscreen" 
    android:theme="@style/AppTheme.NoActionBar" 
      android:noHistory="true"> 
      <intent-filter> 
    <action android:name="android.intent.action.MAIN" /> 
       <category android:name="android.intent.category.LAUNCHER" /> 
      </intent-filter> 
    </activity>

Shiena如果这个代码是对你的工作，然后标记这个问题为您解答。

感谢。有效！！ –
