public void showDialog(Activity activity) {
        final CharSequence[] items = {" No timer ", " 1 minute ", " 3 minute ", " 5 minute ", "10 minute"};

// Creating and Building the Dialog
        AlertDialog.Builder builder = new AlertDialog.Builder(AutumnForest.this);
        builder.setTitle("Set timer duration");
        builder.setSingleChoiceItems(items, selection, new DialogInterface.OnClickListener() {
            public void onClick(final DialogInterface dialog, int item) {
                switch (item) {
                    case 0:
                        if (isRunning) {
                            count_down_timer.cancel();
                            _tv.setVisibility(View.INVISIBLE);
                            gong_imageview.setVisibility(View.INVISIBLE);

                        } else {
                            count_down_timer.cancel();
                            countDownTimer(item);
                            levelDialog.dismiss();
                        }
                        break;
                    case 4:

                        } else {
                            count_down_timer.cancel();
                            countDownTimer(item);
                            levelDialog.dismiss();
                        }
                        break;
                    case 5:                       
                        if (!isRunning) {
                            isRunning = true;
                            countDownTimer(item);
                        } else {
                            count_down_timer.cancel();
                            countDownTimer(item);
                            levelDialog.dismiss();
                        }
                        break;
                    default:
                        Toast.makeText(AutumnForest.this, "Something went wrong please try again", Toast.LENGTH_SHORT).show();
                }
        }
        });
        levelDialog = builder.create();
        levelDialog.show();
    }

代码运行良好但是当点击发生时，它会保留到案例1而不是单击的项目。  我希望如果我点击案例3或4这样的东西应该是setchecked = true和其他setchecked = false但它没有显示。

这是我得到的输出。

尝试使用：

switch (item) {
       case item[0]:
       case item[1]:
                   ...........
