不能包含回收的位圖錯誤

Question

我想將圖像添加到相機surfaceview，並試圖通過使用下面的代碼獲取該圖像。

 else if(v.equals(findViewById(R.id.ok_button))){ 
//    saveImage(); 

       topbar.setVisibility(View.GONE); 
       menubar.setVisibility(View.GONE); 
       bottom.setVisibility(View.GONE); 

       View s = ml.getRootView(); 
       s.setDrawingCacheEnabled(true); 

       Bitmap b = s.getDrawingCache(); 


       Bitmap watermarkimage=b; 
       s.setVisibility(View.GONE); 
       Log.e("ok","ok"); 
       Intent i=new Intent(CameraActivity.this,Update.class); 
       i.putExtra("data",watermarkimage); 
       startActivity(i); 
       finish(); 
       } 

我救了整個活動通過使用下面的代碼，我得到了位圖

View s = ml.getRootView(); 
       s.setDrawingCacheEnabled(true); 

       Bitmap b = s.getDrawingCache(); 

得到image.And當我試圖此位圖發送到另一個活動，我得到這個錯誤

Answer 1

請嘗試製作此位圖的副本或複製副本並將其複製。

Bitmap watermarkimage = b.copy(b.getConfig(), true); 

我會冒險猜測getDrawingCache返回的數據是與b和watermarkimage共享的。所以也許setVisible Gone會導致它回收。
