如果您的意思是预加载器图像有Splash屏幕,请参阅以下代码;

对于PhoneGap:

public class MyDefaultActivity extends Activity {

   public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        super.setIntegerProperty("splashscreen", R.drawable.splash); // Displays the splash screen for android
        super.loadUrl("file:///android_asset/www/index.html",3000); // Second parameter is duration for delay of splash screen
    }
}

对于Android Native应用程序:

public class MySplashScreen extends Activity {
    private CountDownTimer lTimer;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.splashscreen); // Contains only an LinearLayout with backround as image drawable

        lTimer = new CountDownTimer(5000, 1000) {
            public void onFinish() {
                closeScreen();
            }
            @Override
            public void onTick(long millisUntilFinished) {
                // TODO Auto-generated method stub
            }
        }.start();
    }

    private void closeScreen() {
        Intent lIntent = new Intent();
        lIntent.setClass(this, MyLauncherActivity.class);
        startActivity(lIntent);
        finish();
    }
}

确保调用的文件splash.png存在res/drawable-hdpi/splash.png(RGBA).
