不必要的跳過幀錯誤

我收到不必要的跳過消息。該應用程序在其主線程中做了太多工作。在閱讀了幾個答案之後，我意識到要解決它，我必須使用多線程。但我的代碼是非常基本的。不過，我通過使用Async Class在後臺完成工作，重寫了代碼。不必要的跳過幀錯誤

我附加到活動文件的代碼。首先是啓動畫面，另一個是啓動畫面的結果。即使在我手機的屏幕畫面中，我也會產生不必要的延遲。

這是閃屏

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(); 
    } 
} 

}

的代碼是這樣的結果活動

public class gameOptions extends AppCompatActivity { 

int gameTypeCons=0,gameFieldCons=0; 
int difficulty=0; // 0-easy, 1-medium, 2-hard 
int cpu=1;//0-player 1 is cpu, 1- player 2 is cpu

}

後，這是閃屏啓動和啓動畫面效果之間的logcat的。

只要做到下面的代碼爲你的啓動畫面，下面文件替換成splash.java：

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); 
} 

}

它仍然呈現出跳躍1周的時間。但啓動畫面現在很流暢。你能解釋爲什麼這樣做嗎？ –

因爲不需要異步任務，所以在需要從後臺執行一些任務的情況下，需要使用異步任務，例如從服務器獲取數據。在這種情況下，您只需要線程等待3秒鐘，然後移動上其他班級。 – Drv
