觸摸事件池已用盡

Question

我遇到觸摸問題。我有一些單詞精靈，我將觸摸事件（下面）綁定到他們。 連續幾次觸摸其中一個並且想要拖動，首先觸摸事件沒有響應，但是如果我等待一秒鐘，我就可以拖動。在LogCat我得到這個：

12-28 17：23：58.979：V/AndEngine（23295）：org.andengine.util.adt.pool.PoolUpdateHandler $ 1耗盡時，沒有1個項目尚未回收。分配了1個。

如何解決此問題？

這裏是觸摸事件代碼：

public boolean onAreaTouched(TouchEvent pSceneTouchEvent, float pTouchAreaLocalX, float pTouchAreaLocalY) 
{ 
    switch(pSceneTouchEvent.getAction()) { 
     case TouchEvent.ACTION_DOWN: 
      this.mGrabbed = true; 
      break; 

     case TouchEvent.ACTION_MOVE: 
      if(this.mGrabbed) 
       this.setPosition(pSceneTouchEvent.getX() - 18, pSceneTouchEvent.getY() - 15); 
      break; 

     case TouchEvent.ACTION_UP: 
      if(this.mGrabbed) 
      { 
       this.mGrabbed = false; 
       boolean found = false; 
       float x1,x2,y1,y2; 
       if(this.getY() < 350) 
       { 
        for(int i = 0; i < positions_list.size(); i++) 
        { 
         if((word_object_list.get(a).getName().equals(positions_list.get(i).getName())) && positions_list.get(i).isFree()) 
         { 
          x1 = word_object_list.get(a).getSprite().getX(); 
          y1 = word_object_list.get(a).getSprite().getY(); 
          x2 = positions_list.get(i).getxPosition(); 
          y2 = positions_list.get(i).getyPosition(); 
          x1 = Math.abs(x2-x1); 
          y1 = Math.abs(y2-y1); 
          x1 = (float) Math.pow(x1,2); 
          y1 = (float) Math.pow(y1, 2); 
          x1 = x1+y1; 
          x1 = (float) Math.sqrt(x1); 
          if(x1 < 20) 
          { 
           // Set hint's visibility false 
           if(i == 0 && sprite_word_hint_1 != null) 
            sprite_word_hint_1.setVisible(false); 
           if(i == random_hint_position && sprite_word_hint_2 != null) 
            sprite_word_hint_2.setVisible(false); 

           word_object_list.get(a).getSprite().setVisible(false); 
           sprite_word_true_list.get(i).setVisible(true); 
           sprite_candy_list.get(finish_state).setVisible(true); 
           finish_state ++; 

           if(finish_state == question.getWord().length()) 
           { 
            // Create new scene 
            Game_Screen.this.getEngine().registerUpdateHandler(new TimerHandler(6.5f, new ITimerCallback() { 
             public void onTimePassed(TimerHandler pTimerHandler) {

              Game_Screen.this.getEngine().setScene(load_new_scene());

            })); 

            // Increase point 
            Game_Screen.this.getEngine().registerUpdateHandler(new TimerHandler(4.3f, new ITimerCallback() { 
             public void onTimePassed(TimerHandler pTimerHandler) { 
              // TODO Auto-generated method stub 
              int point = variables.getDatabase().get_point(variables.getCategory_level())+question.getWord().length(); 
              elapsedText.setText(""+point); 
              variables.getDatabase().set_answered(question); 
              variables.getDatabase().update_user(question, question.getWord().length(), hint_used); 
             } 
            })); 

            // Cover animation 
            sprite_cover.setRotationCenter(sprite_cover.getRotationCenterX()+20, sprite_cover.getRotationCenterY()); 
            sprite_cover.registerEntityModifier(new SequenceEntityModifier(

Answer 1

我找到了答案。當我多次觸摸精靈時，每當它註冊一個實體修改器並且堆棧正在增長時，我應該等到它爲空。然後我添加了

this.clearEntityModifiers(); 

函數調用觸摸事件的開始，它工作正常。
