理念上实施以下弹出菜单中的ListView [英] Idea on implementing the following pop up menu in ListView

问题描述

我想有弹出菜单，当我点击了3点区域在的ListView 行。

<一个href="http://developer.android.com/reference/android/app/Activity.html#registerForContextMenu%28android.view.View%29"相对=nofollow> registerForContextMenu 将不能满足我的需要，因为它在长期preSS发生，在任何领域的ListView 行。

我也想知道。

1. 如何的ListView 行？创建一个3点看UI
2. 如何拥有PopupMenu的，甚至是Android 2.3的？

解决方案

1. 您可以使用的ImageView 与3个点显示的图像。

2. 有两种方式弹出菜单

   a）使用一些布局和使其可见/不见了

   二）使用 PopupWindow 。

下面是示例$ C $下PopupWindow

  PopupWindow popupWindow =新PopupWindow（上下文）;

查看popUpView = View.inflate（活动的LinearLayout，NULL）;
popUpView.setBackgroundColor（Color.TRANSPARENT）;
mpopup.setContentView（popUpView）;
mpopup.setHeight（LayoutParams.WRAP_CONTENT）;
mpopup.setWidth（LayoutParams.WRAP_CONTENT）;
mpopup.setFocusable（真正的）;
mpopup.setBackgroundDrawable（activity.getResources（）getDrawable（R.drawable.transperent））;
mpopup.setOutsideTouchable（真正的）;
mpopup.setAnimationStyle（R.anim.slide_out_up）;
mpopup.showAtLocation（popUpView，Gravity.TOP，activity.getResources（）
            .getInteger（R.integer.log_out_popup_x），activity.getResources（）
            .getInteger（R.integer.log_out_popup_y））;
 

I would like to have pop up menu, when I click on the 3 dots area in a ListView row.

registerForContextMenu won't meet my need, as it happen during long press, in any area of ListView row.

I would like to know.

1. How to create a 3 dots looking UI in ListView row?
2. How to have PopupMenu, even for Android 2.3?

解决方案

1. You can use ImageView to display image with 3 dots.

2. There are two ways for popupmenu

   a) Use some layouts and make them visible/gone

   b) Use PopupWindow.

here is sample code for PopupWindow

PopupWindow popupWindow = new PopupWindow(context);

View popUpView = View.inflate(activity, linearlayout, null);
popUpView.setBackgroundColor(Color.TRANSPARENT);
mpopup.setContentView(popUpView);
mpopup.setHeight(LayoutParams.WRAP_CONTENT);
mpopup.setWidth(LayoutParams.WRAP_CONTENT);
mpopup.setFocusable(true);
mpopup.setBackgroundDrawable(activity.getResources().getDrawable(R.drawable.transperent));
mpopup.setOutsideTouchable(true);
mpopup.setAnimationStyle(R.anim.slide_out_up);
mpopup.showAtLocation(popUpView, Gravity.TOP, activity.getResources()
            .getInteger(R.integer.log_out_popup_x), activity.getResources()
            .getInteger(R.integer.log_out_popup_y));
