java - Android AlertDialog 关闭方法不起作用

Question

我创建了一个 AlertDialog，但无法关闭它... 我可以看到它并按下按钮，但是当我按下“肯定按钮”时，程序将执行一些任务，然后关闭(关闭)对话框。所有任务都在完成，没有关闭对话框，它只是闪烁一次(它可能会关闭然后重新打开，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();

在退出按钮中放入dialog.dismiss()，然后finish()；

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