android：有什麼看法像隱藏的價值？

我想知道，有任何標準視圖（imageview，imagebutton，textview，按鈕等）像隱藏值？所以我需要設置每個項目的這個值，然後，例如，從onclick事件中查看它。android：有什麼看法像隱藏的價值？

我的應用程序崩潰ImageButton手機=（ImageButton）findViewById （R.id.item_phones_button）; \t \t \t phones.setTag（「asd」）; – yital9 2012-07-11 10:04:31

您能提供錯誤日誌嗎？ – vasart 2012-07-11 10:05:30

爲了設置可見於任何視圖例如，你可以這樣做：

View myView = (View)findViewById(R.id.myview); 
myView.setVisibility(View.GONE); 
//or 
myView.setVisibility(View.VISIBLE); 
//or 
myView.setVisibility(View.HIDDEN);

您可以檢查這裏的DOC：http://developer.android.com/reference/android/view/View.html#setVisibility%28int%29

您可以使用setContentDescription（String str）和getContentDescription（）與您提到的所有視圖。

但

那不是來處理這件事情的正確方法。就應該把延長任一視圖類或onclicklistener

例如：

public class myClickListener implements View.OnClickListener{ 

     private int hiddenValue; 
     public myClickListener(int hiddenValue){ 
      this.hiddenValue=hiddenValue; 
     } 

     @Override 
     public void onClick(View v) { 
      hiddenValue++; 
     } 

    }

然後你.setonlicklistener稱之爲（新myClickListener（5））;
