我创建了一个运行良好的 AlertDialog.它正在消失，如果我按下:1) 转义键盘按钮或 2) 使用鼠标的后退按钮 为了使其即使在上述条件下也能保持专注，我在构建时添加了 '.setCancelable(false)' 语句.但是，我仍然看到对话框消失了.问题出在哪儿?请帮忙.

I had created an AlertDialog which is working fine. It is disappearing, if I press: 1) escape keyboard button or 2) back button using mouse To make it stay focused even on above stated conditions, I had added '.setCancelable(false)' statement while building. But, I still see dialog disappearing. Where is the problem? Please help.

添加的代码:

return new AlertDialog.Builder(getActivity()) .setIcon(R.drawable.alert_dialog_icon) .setTitle(title) .setCancelable(false) .setPositiveButton(R.string.alert_dialog_ok, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int whichButton) { ((FragmentAlertDialog)getActivity()).doPositiveClick(); } } ) .setNegativeButton(R.string.alert_dialog_cancel, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int whichButton) { ((FragmentAlertDialog)getActivity()).doNegativeClick(); } } ) .create();
