Question

这是我创建对话框的代码

public void onClick(View v) 
            {
                try{ 
                  Builder dialog= new AlertDialog.Builder(context);
                     dialog.setTitle(R.string.dialog_title1);
                     dialog.setMessage(R.string.url);
                     dialog.setPositiveButton(R.string.dialog_ok, null);
                     dialog.show();
                    }

我想为SetPositive按钮添加一个事件监听器（OK按钮）。单击确定时应关闭我的应用程序，即用户应退出应用程序。任何人都可以帮我实现这个目标吗？

Answer 1

dialog.setPositiveButton(R.string.dialog_ok, new DialogInterface.OnClickListener() {
  public void onClick(DialogInterface dialog, int id) {
    MyActivity.this.finish();         
  }
});

试试这个：

        new AlertDialog.Builder(this)
        .setTitle("XYZ")
        .setMessage("Do you want to Exit ?")
        .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) {
                // TODO Auto-generated method stub

                MyActivityClass.this.finish();
                        dialog.dismiss();
                        }
        })
        .setNeutralButton("No", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) {
                // TODO Auto-generated method stub
                dialog.dismiss();                   
            }
            })          
        .create()
        .show();

试用此代码

Builder dialog = new AlertDialog.Builder(this);
        dialog.setTitle("Message");
        dialog.setMessage("Exit App?");
        dialog.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                // Enter your Code for exit Application
            }
        });
        dialog.show();

                HomeActivity.this.finish();

                }
            });
