我已经看到很多关于通过将null或新的Drawable()传递给setBackgroundDrawable()来删除PopupWindow边框的问题.我遇到了相反的问题.我想在我的PopupWindow周围有一个边框,最好带有指向我的锚点的工具提示箭头.目前,我的PopupWindow没有边框.我已经尝试调整边距,xml中的背景,布局的宽度和高度,listview和listview行无济于事.有人可以请帮助我在顶部获得边框和图像吗？我试图坚持使用Android SDK.

popup_menu_list.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"    
    android:orientation="vertical" >

    <com.github.jeremiemartinez.refreshlistview.RefreshListView
        android:id="@+id/popup_menu_list_listview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@color/color_white" />

</LinearLayout>

Java的

private void displayPopupMenu() {
        LayoutInflater layoutInflater = getLayoutInflater();
        View popupView = layoutInflater.inflate(R.layout.popup_menu_list, null);        
        final PopupWindow popupWindow = new PopupWindow(popupView, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);       
        RefreshListView myListView = (RefreshListView) popupView.findViewById(R.id.popup_menu_list_listview);       
        mAdapter = new myAdapter(this, getAdapterData());       
        myListView.setAdapter(mAdapter);            
        popupWindow.showAsDropDown(mMyAnchor);      
    }

我只是抓住这些作为例子,但我想要这样的东西弹出指向锚点:

但我得到这样的东西:

我已经打了一个Activity电话Accounts,我想添加一个横向ContextMenu.这可能看起来像剪切,复制和粘贴选项.有没有办法onLongClick在列表项上添加这个水平自定义菜单？

这是我到目前为止所得到的.

@Override      
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) {
    super.onCreateContextMenu(menu, v, menuInfo);
    LayoutInflater inflater = getLayoutInflater().from(this);
    View view = inflater.inflate(R.layout.custom_listview, null, false);
    menu.setHeaderView(view);
    menu.add("Delete");
    menu.add("Edit");
}

@Override
public boolean onContextItemSelected(MenuItem item) {
    AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) item.getMenuInfo();
    int position = info.position;
    View v = listView.getChildAt(position);
    TextView typeTv = v.findViewById(R.id.custom_listview_type);
    TextView userTv = v.findViewById(R.id.custom_listview_user);
    TextView passTv = v.findViewById(R.id.custom_listview_password);

    if (item.getTitle().equals("Delete")) {
        db.execSQL("delete from user_added_accounts where accountType = '" + typeTv.getText().toString() …
