初始屏幕不會轉換到我的主菜單屏幕

Question

我目前正在開發一個應用程序，該應用程序應該從啓動屏幕轉換到主菜單屏幕。我已經完成了編碼，但似乎沒有這樣做。任何人都可以發現下面的代碼有什麼問題嗎？

閃屏活動：

public class MainActivity extends Activity { 

public static final String GAME_PREFERENCES = "GamePrefs"; 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.splash); 

    // fade in animation 
    TextView logo1 = (TextView)findViewById(R.id.TextViewTopTitle); 
    Animation fade1 = AnimationUtils.loadAnimation(this, R.anim.fade_in); 
    logo1.startAnimation(fade1); 

    // custom animation 
    Animation spining = AnimationUtils.loadAnimation(this, R.anim.custom_anim); 
    LayoutAnimationController controller = new LayoutAnimationController(spining); 
    TableLayout table = (TableLayout)findViewById(R.id.TableLayout01); 
    for(int i=0; i < table.getChildCount(); i++) 
    { 
     TableRow row = (TableRow) table.getChildAt(i); 
     row.setLayoutAnimation(controller); 
    } 

    startAnimations(); 

    // saving game preferences 
    SharedPreferences settings = getSharedPreferences(GAME_PREFERENCES, MODE_PRIVATE); 
    SharedPreferences.Editor prefEditor = settings.edit(); 
    prefEditor.putString("UserName", "JaneDoe"); 
    prefEditor.putInt("UserAge", 22); 
    prefEditor.commit(); 
} 

private void startAnimations() { 
    // Transition from Splash screen to Main Menu screen 
    Animation fade2 = AnimationUtils.loadAnimation(this, R.anim.fade_in2); 
    fade2.setAnimationListener(new AnimationListener() { 
     public void onAnimationEnd(Animation animation) 
     { 
      startActivity(new Intent(MainActivity.this,QuizMenuActivity.class)); 
      MainActivity.this.finish(); 
     } 
     public void onAnimationStart(Animation animation) 
     { 
      //Nothing 
     } 
     public void onAnimationRepeat(Animation animation) 
     { 
      //Nothing 
     } 
    }); 
} 

主菜單活動：

public class QuizMenuActivity extends Activity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     // TODO Auto-generated method stub 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.menu); 
    } 
} 

我的佈局已經完成。有什麼問題在這裏有什麼建議嗎？

也許AnimationListener永遠不會被觸發？如果你只是想要初始屏幕顯示然後離開..怎麼樣只是想添加以下到您的飛濺活動的onCreate：

Thread timer = new Thread() {   
    public void run() {    
     try {     
      sleep(5000); // Sets delay before splash appears   
     } catch (InterruptedException e) { 
      e.printStackTrace();     
     } finally { 
      Intent main = new Intent(Splash.this, MainMenu.class); 
      startActivity(main);  
      finish(); 
     }  
    }; 
    timer.start(); 

它休眠5秒鐘，然後進入到MainMenu的。

編輯

我想是永遠不會被調用你的AnimationListener，所以儘量增加fade2.startNow()這裏：

private void startAnimations() { 
    // Transition from Splash screen to Main Menu screen 
    Animation fade2 = AnimationUtils.loadAnimation(this, R.anim.fade_in2); 
    fade2.setAnimationListener(new AnimationListener() { 
    public void onAnimationEnd(Animation animation) 
    { 
     startActivity(new Intent(MainActivity.this,QuizMenuActivity.class)); 
     MainActivity.this.finish(); 
    } 
    public void onAnimationStart(Animation animation) 
    { 
     //Nothing 
    } 
    public void onAnimationRepeat(Animation animation) 
    { 
     //Nothing 
    } 
}); 
fade2.startNow(); 
}

animation.start() or animation.startNow() does not start the animation immediately
