单击列表视图打开自定义对话框

Question

如何在单击基础适配器的列表项时打开自定义对话框？

我尝试使用代码通过单击项目列表打开自定义对话框，但得到窗口管理器的错误

 public void onItemClick(AdapterView<?> arg0, View view, int position,
                long arg3) {

            int childPosition = ExpandableListView.getPackedPositionChild(position);
            int tempID = childPosition;
            Log.i("tempID",""+tempID);
            Log.i("Item Clicked","Position"+position);


            //Log.i("Item Clicked","Position"+position);    

            type_dilog = new Dialog(Contacts.this);
            type_dilog.setContentView(R.layout.dialogg);

            type_dilog.setTitle(" Select the Operation ");
            Log.i("3333333333","333333333");
            TextView alert_messagee = (TextView) type_dilog.findViewById(R.id.dilog_messagee);
            alert_messagee.setVisibility(View.GONE);
            imageBtn = (Button) type_dilog.findViewById(R.id.automessage_btn);
            videoBtn = (Button) type_dilog.findViewById(R.id.ownmessage_btn);
            captuerimageBtn = (Button) type_dilog.findViewById(R.id.captureimage_btn);
            takevideoBtn = (Button) type_dilog.findViewById(R.id.takevideo_btn);
            delete = (Button) type_dilog.findViewById(R.id.delete_btn);
//              delete_no = (Button) type_dilog.findViewById(R.id.delete_no_btn);
            Log.i("44444444","4444444444");
            imageBtn.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT,LinearLayout.LayoutParams.WRAP_CONTENT));
            videoBtn.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT,LinearLayout.LayoutParams.WRAP_CONTENT));
            captuerimageBtn.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT,LinearLayout.LayoutParams.WRAP_CONTENT));
            takevideoBtn.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT,LinearLayout.LayoutParams.WRAP_CONTENT));
            delete.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT,LinearLayout.LayoutParams.WRAP_CONTENT));

            delete.setVisibility(View.GONE);

            imageBtn.setText("Photo Library");
            videoBtn.setText("Video Library");
            captuerimageBtn.setText("Take Picture");
            takevideoBtn.setText("Take Video");


            type_dilog.show();

}

上面是想要打开自定义对话框时点击onItemClick时出现的Log cat错误

我写 type_dilog = new Dialog(getParent());而不是 type_dilog = new Dialog(Contacts.this);它解决了我的问题
