如何在overrided onback pressed获取super.onback pressed（）的行为（） [英] how to Get behaviour of super.onbackpressed() within overrided onbackpressed()

问题描述

我试图用确认对话框回去，这样我决定来处理onback pressed（），然后我已经把我的code代表与空监听确定和取消按钮确认对话框。
结果

  @覆盖
公共无效onBack pressed（）{
AlertDialog.Builder建设者=新AlertDialog.Builder（本）;
    builder.setTitle（确认书）;
    builder.setMessage（你确定要退出吗？）;
    builder.setPositiveButton（OK，NULL）;
    builder.setNegativeButton（取消，NULL）;
    builder.show（）;
}
 

结果它工作得很好，但如果我点击确定，但应该继续（）pssed super.onback $ P $，否则就应该在同一活动的行为问题。
结果
以下code，我曾试图。
结果

  @覆盖
公共无效onBack pressed（）{
    AlertDialog.Builder建设者=新AlertDialog.Builder（本）;
    builder.setTitle（确认书）;
    builder.setMessage（你确定要退出吗？）;
    builder.setPositiveButton（OK，新DialogInterface.OnClickListener（）{        @覆盖
        公共无效的onClick（DialogInterface对话，诠释它）{
            //super.onBack$p$pssed（）;
        }
    }）;
    builder.setNegativeButton（取消，NULL）;
    builder.show（）;
}
 

解决方案

把this.finish（）来完成您的活动正按钮的onclick ...

  builder.setPositiveButton（OK，新DialogInterface.OnClickListener（）{    @覆盖
    公共无效的onClick（DialogInterface对话，诠释它）{
        //super.onBack$p$pssed（）;
         this.finish（）;
    }
}）;
 

I was tried to go back with confirmation dialog so that i was decided to handle onbackpressed() and then i had put my code for confirm dialog with ok and cancel button for null listener.

@Override
public void onBackPressed() {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("Confirmation");
    builder.setMessage("Are you sure want to exit?");
    builder.setPositiveButton("OK",null);
    builder.setNegativeButton("Cancel", null);
    builder.show();   
}

It was worked fine but the problem is if i click ok but it should continue for behaviour of super.onbackpressed() otherwise it should be in same activity.
the following code that i had tried.

@Override
public void onBackPressed() {
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("Confirmation");
    builder.setMessage("Are you sure want to exit?");
    builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {

        @Override
        public void onClick(DialogInterface dialog, int which) {
            //super.onBackPressed();
        }
    });
    builder.setNegativeButton("Cancel", null);
    builder.show();   
}

解决方案

put this.finish() to finish your activity in onclick of positive button ...

builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {

    @Override
    public void onClick(DialogInterface dialog, int which) {
        //super.onBackPressed();
         this.finish();
    }
});
