Answer 1

나는 같은 뷰가 여러 개에 첨부 할 수 없습니다 수 없기 때문에 문제가이 toast.setView(arg1);에서 코드에있다 생각 사물. 이보기는 이미 갤러리 항목에 첨부되어 있습니다.

업데이트 당신은 단지 현재보기의 동일한 값을 사용 layoutInflator하여 해당보기를 다시 다음 토스트에 새로운보기를 통과해야합니다.

Answer 2

.

그것은 당신이 먼저 갤러리에서 제거하지 않는 한 Toast에 첨부 할 수 없음을 의미

Answer 3

UI 항목에 'getApplicationContext()'를 사용하지 말고 대신 Activity 컨텍스트를 사용하십시오. 예.

public class MyListener implements AdapterView.OnItemClickListener { 

    private final Context mContext; 

    public MyListener(Activity ctx) { 
     mContext = ctx; 
    } 

    @Override 
    public void onItemClick(AdapterView arg0, View arg1, int arg2, long arg3) { 
     Toast toast = new Toast(mContext); 
     toast.setView(arg1); 
     toast.show(); 

    }}

더 좋은 물건을 단순화하기 위해 활동에 AdapterView.OnItemClickListener을 구현하는 것입니다 :

public class MainActivity implements AdapterView.OnItemClickListener { 
//start onCreate 
gal.setOnItemClickListener(this); 
//end onCreate 

@Override 
    public void onItemClick(AdapterView arg0, View arg1, int arg2, long arg3) { 
     Toast toast = new Toast(this); 
     toast.setView(arg1); 
     toast.show(); 

    }}
