如何在我的android电视应用程序中添加闪屏？

public class SplashActivity extends Activity {
    private static final int SPLASH_DISPLAY_TIME = 3000; // 闪屏显示时间为3秒

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

        new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                // 延迟跳转到主界面
                Intent mainIntent = new Intent(SplashActivity.this, MainActivity.class);
                startActivity(mainIntent);
                finish();
            }
        }, SPLASH_DISPLAY_TIME);
    }
}

<activity
    android:name=".SplashActivity"
    android:theme="@style/Theme.AppCompat.NoActionBar">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

</RelativeLayout>
