Android AlertDialog解僱方法不起作用

Question

我創建了一個AlertDialog，但我無法關閉它... 我可以看到它並按下按鈕，但是當我按下「正面按鈕」時，程序應做一些任務，然後關閉（關閉）對話框。所有的任務都在完成，沒有關閉對話框，它只是閃爍一次（它可能會關閉然後重新打開，我不知道）。

AlertDialog.Builder builder = new AlertDialog.Builder(myContext); 
     builder.setTitle("Congratulations, you won!"); 
     builder.setMessage("Time: x seconds\nScore: xxxx\nHigh score: yyyy"); 
     builder.setPositiveButton("Play again!", 
       new DialogInterface.OnClickListener() { 
        @Override 
        public void onClick(DialogInterface dialog, int which) { 
         // Doing stuff! 
         circle1Paint = yellowPaint; 
         circle2Paint = yellowPaint; 
         circle3Paint = yellowPaint; 
         playing = true; 


         // Trying to close it after doing "the stuff" 
         dialog.dismiss(); 
        } 
       }); 
     builder.setNegativeButton("Exit", 
       new DialogInterface.OnClickListener() { 
        @Override 
        public void onClick(DialogInterface dialog, int which) { 
         System.exit(0); 
        } 
       }); 
     builder.create.show(); 

在此先感謝！ CoderOgden

Answer 1

進入退出按鈕放入dilog.dissmiss（），然後完成（）;

builder.setNegativeButton("Exit", 
      new DialogInterface.OnClickListener() { 
       @Override 
       public void onClick(DialogInterface dialog, int which) { 
        dialog.dismiss(); 
        finish(); 
       } 
      });

試試這個代碼：

AlertDialog.Builder builder = new AlertDialog.Builder(myContext); 
    builder.setTitle("Congratulations, you won!"); 
    builder.setMessage("Time: x seconds\nScore: xxxx\nHigh score: yyyy"); 

    builder.setNegativeButton("Exit", 
      new DialogInterface.OnClickListener() { 
       @Override 
       public void onClick(DialogInterface dialog, int which) { 
        System.exit(0); 
       } 
      }); 
    AlertDialog myDialog = builder.create(); 
    builder.setPositiveButton("Play again!", 
      new DialogInterface.OnClickListener() { 
       @Override 
       public void onClick(DialogInterface dialog, int which) { 
        // Doing stuff! 
        circle1Paint = yellowPaint; 
        circle2Paint = yellowPaint; 
        circle3Paint = yellowPaint; 
        playing = true; 


        // Trying to close it after doing "the stuff" 
        myDialog.dismiss(); 
       } 
      }); 
    myDialog.show();
