如何删除视图对孩子的父母？机器人 [英] How to remove view on the child's parent? android

问题描述

所以，我有一个按钮，当点击它显示一个警告对话框。我创建视图在我活动的onCreate方法警告对话框。在code因为这是在这里：

So i have a button that displays an alert dialog when its clicked. I create the view for the alert dialog in the onCreate method of my activity. The code for that is right here:

    LayoutInflater factory = LayoutInflater.from(this);
    view = factory.inflate(R.layout.grade_result, null);

当我按下按钮，第一次，对话框显示我想要的方式，但是当我推第二次，它抛出此异常

When i push the button for the first time, the dialog displays the way i want it, but when i push it a second time it throws this exception

11-28 00：35：58.066：E / AndroidRuntime（30348）：java.lang.IllegalStateException：产生的原因指定的孩子已经有一个父。你必须先调用removeView（）孩子的父母。

11-28 00:35:58.066: E/AndroidRuntime(30348): Caused by: java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

我的$ C $下显示的AlertDialog当按下按钮的方法就在这里：

My code for the method that displays the AlertDialog when the button is pushed is right here:

public void details(View v){
    final AlertDialog.Builder alert = new AlertDialog.Builder(this);
    alert.setView(view);
    alert.setMessage("Details About Your Grades")
    .setCancelable(false)
    .setPositiveButton("Continue", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int id){
            dialog.cancel();

        }
    });
    alert.show();

任何帮助将是AP preciated！谢谢！

Any help would be appreciated! Thank you!

推荐答案

充气工作对我来说，应该在AlertDialog的生成器内设置的观点：

Inflating the view that should be set within the Builder of the AlertDialog worked for me :

Button mButton = (Button) findViewById(R.id.my_button);
mButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // inflating view out of the onClick() method does not work
            LayoutInflater mInflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            final ViewGroup viewGroup= (ViewGroup) mInflater.inflate(R.layout.my_view, null);

            Dialog alertDialog = new AlertDialog.Builder(getActivity())
                    .setTitle(R.string.my_title)
                    .setView(viewGroup)
                    .setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            dialog.dismiss();
                        }
                    }).create();
            alertDialog.show();
        }
}
