解决方案

您需要运行在此AsyncTask的两个动作：

 的setContentView（R.layout.splashscreen）;
randomSplash（）;
 

把的setContentView 在doInBackground-方法和运行 randomSplash 的postExecute方法。

I have an issue with my SplashScreenActivity, when I start my application on my phone it shows a white screen for about 0,5 seconds. The MainActitivy extends FragmentActivity and in the AndroidManifest I declare the SplashScreenActivity as launcher and portrait mode as screenOrientation.

The code:

public class SplashScreenActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.splashscreen);
    randomSplash();

    Thread splashscreen = new Thread() {

        public void run() {
            try {
                Thread.sleep(1000);
                Intent mainScreen = new Intent("com.rm.jkrm.MAINACTIVITY");
                startActivity(mainScreen);
            } catch (InterruptedException e) {

            } finally {
                finish();
            }
        }
    };
    splashscreen.start();
}

private void randomSplash(){
    Random random = new Random();
    int i = random.nextInt(4);

    LinearLayout ln = (LinearLayout) findViewById(R.id.splashscreen);

    switch(i){
    case 1: 
        ln.setBackgroundResource(R.drawable.splash1);
        break;
    case 2: 
        ln.setBackgroundResource(R.drawable.splash2);
        break;
    case 3: 
        ln.setBackgroundResource(R.drawable.splash3);
        break;
    default: 
        ln.setBackgroundResource(R.drawable.splash0);
        break;
    }
}
}

XML:

 <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:id="@+id/splashscreen"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:orientation="vertical">
</LinearLayout>

解决方案

You need to run this two actions in an AsyncTask:

setContentView(R.layout.splashscreen);
randomSplash();

put the setContentView in the doInBackground-method and in the postExecute method you run randomSplash.
