java - Android 警报确认对话框

Question

伙计们，我一直在努力解决这个问题，但我做不到

我希望当用户单击 btn_delete 时他会收到一条消息以确保删除(是或否)，我尝试了很多方法但我不知道到底是什么问题，我是新手在 Android 编程中请原谅我的愚蠢问题，这是我的 Java 代码:

public void onDeleteClick(View v) {
    int i = Integer.parseInt((String)v.getTag());
    Address address = _list.get(_currentPage*PANELS_PER_PAGE + i);
    _dbAdapter.deleteAddress(address.Id);

    _GetAddresses();
}

Answer 1

用下面的方法替换onDeleteClick方法:

public void onDeleteClick(View v) {
    int i = Integer.parseInt((String)v.getTag());

    AlertDialog.Builder alert = new AlertDialog.Builder(AddressListActivity.this);
    alert.setTitle("Delete");
    alert.setMessage("Are you sure you want to delete?");
    alert.setPositiveButton("Yes", new DialogInterface.OnClickListener() {

        @Override
        public void onClick(DialogInterface dialog, int which) {
            Address address = _list.get(_currentPage*PANELS_PER_PAGE + i);
            _dbAdapter.deleteAddress(address.Id);

            _GetAddresses();

            dialog.dismiss();
        }
    });

    alert.setNegativeButton("No", new DialogInterface.OnClickListener() {

        @Override
        public void onClick(DialogInterface dialog, int which) {
                dialog.dismiss();
        }
    });

    alert.show();
}
