在對話框中顯示圖像

Question

我有一個圖像，我目前正在將它設置在imageview上。

我希望當點擊Imageview時，會彈出一個對話框，顯示圖像..任何方法我怎麼能實現這一點。

   Context mContext = getApplicationContext(); 
       Dialog dialog = new Dialog(mContext); 

       dialog.setContentView(R.layout.customdialog); 
       dialog.setTitle("wateva"); 

       ImageView ivDialog = (ImageView) dialog.findViewById(R.id.ivDialog); 
       String filepath = Environment.getExternalStorageDirectory().getPath(); 
       folder = new File(filepath,"checking"); 

       File fa = new File(folder,"bmp1.png"); 
       Bitmap bmpa = BitmapFactory.decodeFile(fa.getAbsolutePath()); 
       Log.d("error " , "here"); 
       ivDialog.setImageBitmap(bmpa); 
       dialog.show();

使用CustomDialog爲.Create佈局具有ImageView的行吟詩人和組件並將其設置爲對話框。

Dialog dialog = new Dialog(this); 
dialog.setContentView(R.layout.dialoglayout); 
ImageView imgView=(ImageView)dialog.findViewById(R.id.imagview); 
//set image to imgView 
dialog.show();
