我已经实现了以下代码来显示自定义警报对话框,但是当我调用此对话框时,它显示异常:
WindowManager.BadTokenException
public static void showAlertDialog(final String title, String message,
final Context context, final boolean redirectToPreviousScreen) {
AlertDialog.Builder alertbox = new AlertDialog.Builder(context);
alertbox.setMessage(message);
alertbox.setTitle(title);
alertbox.setNeutralButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface arg0, int arg1) {
}
});
try{
alertbox.show();
}catch (Exception b) {
}
