我在活动中，pressing按钮赖以，下面的方法被调用 -

I have a button in my activity, pressing upon which, the following method gets called -

private ArrayList<ListView> myListViewList; private ArrayList<MyListAdapter> myAdapterList; public void onPopupButtonClick(View button) { Log.v(TAG, "onPopupButtonClick"); PopupMenu popup = new PopupMenu(this, button); Menu menu = popup.getMenu(); // how do i display the myListViewList as items of in this popup menu // i.e how do i inflate myListViewList into menu object? }

推荐答案

勾选此code的弹出式窗口

Check this code for Pop-up window

LayoutInflater inflater = (LayoutInflater) PopupMain.this.getSystemService(Context.LAYOUT_INFLATER_SERVICE); final View layout = inflater.inflate(R.layout.popup, (ViewGroup)findViewById(R.id.popup_menu_root)); PopupWindow pw = new PopupWindow(layout, 300,100, true); pw.dismiss(); pw.showAtLocation(layout, Gravity.BOTTOM, 0, 10);

和您的新弹出的布局应该如下：

And your New pop-up layout should be as follows :

Popup.xml：

Popup.xml :

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="schemas.android/apk/res/android" android:id="@+id/popup_menu_root" android:background="#FFFFFF" android:orientation="vertical" android:layout_width="wrap_content" android:layout_height="20dip" > <TextView android:id="@+id/popup_menu_button1" android:text="Copy" android:textColor="#000000" android:layout_width="fill_parent" android:layout_height="wrap_content" /> </LinearLayout>

这行决定新视图（弹出窗口）的高度和宽度

This line decide the Height and width of your New View(Pop up window)

PopupWindow pw = new PopupWindow(layout, 300,100, true);

和 pw.showAtLocation（布局，Gravity.BOTTOM，0，10）;

告诉那里的弹出窗口显示应该..

tells where the Pop-up window should displays..
