Question

当我在警告对话框中setNegativeButton和setPositiveButton时，我在我的移动设备上运行它，这是一个Hauweii手机。运行完美，但是当我在模拟器上运行时，alertDialog显示但是没有显示确定或取消但我仍然可以点击它们，它就像是看不见的东西，有人可以帮助我吗？

       listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        public void onItemClick(AdapterView<?> a, View v, int position, long   id) {

            AlertDialog.Builder alertD=new AlertDialog.Builder(Report.this);
            alertD.setTitle("Delete?");
            alertD.setMessage("Are you sure you want to delete your Bmi ");
            final int positionToRemove = position;

            alertD.setNegativeButton("Ok", null);
            alertD.setPositiveButton("Cancel", new  AlertDialog.OnClickListener() {

                public void onClick(DialogInterface dialog, int which) {
                    bmis.remove(positionToRemove);
                    b.notifyDataSetChanged();
                }});

            alertD.show();
        }
    });

在onItemClick

中

AlertDialog.Builder alertDialog = new AlertDialog.Builder(Report.this);
final int positionToRemove = position;
alertDialog.setTitle("Delete?");
alertDialog.setMessage("Are you sure you want to delete your Bmi "));

// Setting Positive "YES" Button
alertDialog.setPositiveButton("YES", new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int which) {
        bmis.remove(positionToRemove);
        b.notifyDataSetChanged();
        dialog.dismiss();
    }
});

// Setting Negative "CANCEL" Button
alertDialog.setNegativeButton("CANCEL", new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int which) {
        dialog.dismiss();
    }
});

// Showing Alert Message
alertDialog.show();

在模拟器上不起作用的否定和正面按钮
