我收到了不必要的跳过消息。应用程序在其主线程中做了太多工作。在阅读了几个答案后，我意识到要解决它，我必须使用多线程。但我的代码非常基本。尽管如此，我还是通过使用Async Class在后台完成工作来重写代码。
我附加到活动文件的代码。首先是启动画面，另一个是启动画面的结果。即使在我的手机屏幕上，我也会遇到不必要的延迟。
这是启动画面的代码
package bt4u.com.pokemonbattles;
public class splash extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
System.out.println("Splash screen activity (splash.java)");
new myClass().execute();
}
class myClass extends AsyncTask<Void,Void,Void> {
@Override
protected Void doInBackground(Void... params) {
try {
Thread.sleep(3000);
} catch (InterruptedException e) {
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(Void aVoid) {
Intent intent=new Intent(splash.this,gameOptions.class);
startActivity(intent);
finish();
}
}
}
这是结果活动之后的

只需为您的启动画面执行以下代码，将splash.java替换为以下文件：
public class splash extends Activity {
// Splash screen timer
private static int SPLASH_TIME_OUT = 3000;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
new Handler().postDelayed(new Runnable() {
/*
* Showing splash screen with a timer. This will be useful when you
* want to show case your app logo / company
*/
@Override
public void run() {
// This method will be executed once the timer is over
// Start your app main activity
Intent i = new Intent(splash.this, gameOptions.class);
startActivity(i);
// close this activity
finish();
}
}, SPLASH_TIME_OUT);
}
}
