推荐答案

您可以使用警报生成器这样的：

You could use the alert builder for this:

new AlertDialog.Builder(context) .setTitle("Delete entry") .setMessage("Are you sure you want to delete this entry?") .setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { // continue with delete } }) .setNegativeButton(android.R.string.no, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { // do nothing } }) .setIcon(android.R.drawable.ic_dialog_alert) .show();
