我有一个FragmentActivity由许多元素组成的元素，这些元素会在每个关于该项目的项目上显示一个弹出窗口，我正在以常规方式创建弹出窗口：

LayoutInflater inflater;
View layout;
inflater = (LayoutInflater) MyActivity.this
        .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
layout = inflater.inflate(R.layout.my_popup_layout,
        (ViewGroup) findViewById(R.id.my_popup));

这种方式在单击任何项​​目时非常有效，但这只是在单击应用程序时崩溃并引发的一项system services not available exception：

单击时发生此行为的项目是唯一以编程方式创建的项目：

 Button rooms = new Button(MyApplication.getAppContext());
 container_layout.addView(rooms);
 params = (RelativeLayout.LayoutParams) rooms.getLayoutParams();
 params.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
 rooms.setLayoutParams(params);
 rooms.setTag(sys_id);
 rooms.setTag(R.string.app_name, zone_name.getText());
 rooms.setBackgroundResource(R.drawable.a_drawable_button_drawable);
 rooms.setText(R.string.rooms);
 rooms.setTextColor(Color.WHITE);
 rooms.setTextSize(TypedValue.COMPLEX_UNIT_SP, 15);
 rooms.setPadding(5, 3, 5, 3);
 rooms.setOnClickListener(on_zone_roomsClick);
