使用 android 处理程序的启动画面不工作

Question

我的启动画面不工作。它只是闪烁一个空布局 2 秒并加载 mainactivity ... 我已经从 drawable 添加了一个 png 图像作为初始屏幕的 android:background。但它不显示图像.. 我也试过在启动画面中使用文本字段，但它再次显示一个空布局..

这是我的初始屏幕活动代码

public class SplashScreenActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //setContentView(R.layout.activity_splash_screen);

    //Handler handler = new Handler();

    // run a thread after 2 seconds to start the home screen
    //handler.postDelayed(new Runnable() {
    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {

            // make sure we close the splash screen so the user won't come
            // back when it presses back key

            finish();
            // start the home screen

            Intent intent = new Intent(SplashScreenActivity.this,
                    MainMenuActivity.class);

            startActivity(intent);


        }

    }, 2000); // time in milliseconds (1 second = 1000 milliseconds) until
                // the run() method will be called

}

}

这是我的初始屏幕代码，它正在运行：

    @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_splash_screen);

    int SPLASH_TIME_OUT = 1500;
    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            startActivity(new Intent(SplashScreenActivity.this, DrawerActivity.class));
            finish();
        }
    }, SPLASH_TIME_OUT);
}
