[1]PopupWindow兑现弹出窗口
    来源: 互联网  发布时间: 2014-02-18
PopupWindow实现弹出窗口
点击ListView的每一个item，将弹出窗口显示item详情

主要代码:
private void openPopupwin() {
		LayoutInflater mLayoutInflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
		ViewGroup rootView = (ViewGroup) mLayoutInflater.inflate(R.layout.person_info_pop, null, true);
		
		TextView person_popup_name = (TextView)rootView.findViewById(R.id.person_popup_name);
		TextView person_popup_realName = (TextView)rootView.findViewById(R.id.person_popup_realName);
		TextView person_popup_age = (TextView)rootView.findViewById(R.id.person_popup_age);
		TextView person_popup_birthday = (TextView)rootView.findViewById(R.id.person_popup_birthday);
		TextView person_popup_phone = (TextView)rootView.findViewById(R.id.person_popup_phone);
		TextView person_popup_deptId = (TextView)rootView.findViewById(R.id.person_popup_deptId);
		Button btn_popup_close = (Button)rootView.findViewById(R.id.btn_popup_close);
		ImageView person_popup_head = (ImageView)rootView.findViewById(R.id.person_popup_head);
		
		try {
			person_popup_name.setText(selectedperson.getString("name"));
			person_popup_realName.setText(selectedperson.getString("realName"));
			person_popup_age.setText(selectedperson.getString("age"));
			person_popup_birthday.setText(selectedperson.getString("birthday"));
			person_popup_phone.setText("13880012450");//还未添加字段
			person_popup_deptId.setText("产品事业部");
			person_popup_head.setBackgroundDrawable(ImageUtil.geRoundDrawableFromUrl(HttpUtil.BASE_URL+selectedperson.getString("headPhotoPath"), 10));
		} catch (JSONException e) {
			e.printStackTrace();
		} catch (Exception e) {
			e.printStackTrace();
		}
		
		popupWindow = new PopupWindow(rootView, LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT, true);
		popupWindow.setBackgroundDrawable(new BitmapDrawable());
		popupWindow.setAnimationStyle(R.style.PopupAnimation);
		popupWindow.showAtLocation(root, Gravity.CENTER | Gravity.CENTER, 0, 0);
		popupWindow.update();
		
		btn_popup_close.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View v) {
				popupWindow.dismiss();
			}
		});
	}

弹出窗口布局文件:

 android:layout_weight="1" 可叫 “权重”

此属性指定该标签在一个布局当中占x/y的空间
