如何用列表popupwindow替换popupmenu代码？

目前，我正在编程创建一个popupmenu，其中显示一个楼层和标题的列表。但是，改变标题的背景颜色并为标题添加一个关闭按钮将变成一场噩梦。如何用列表popupwindow替换popupmenu代码？

我想用列表弹出窗口替换这个popupmenu，这样我就可以为背景属性添加一个带有黑色背景属性的XML文件作为背景，并且菜单中项目的右侧和白色背景上的关闭按钮。有没有一种方法可以通过列表弹出窗口实现这一点？这里是我的代码为：

private void floorMenu(ImageView btnFloorMenu){ 
    MapData data = new MapDao(MyPlugin.mapId); 
    final List<Floor> flList = dao.getFloors(); 
    // set popupMenu 
    final PopupMenu floorsPm = new PopupMenu(MapViewActivity.this,btnFloorMenu); 

    MenuItem titleItem = floorsPm.getMenu().add(Menu.NONE, Menu.NONE, Menu.NONE, "Floors"); 

    int i = 1; 
    for(Floor fl : flList) 
    { 
     floorsPm.getMenu().add(Menu.NONE, i,i, fl.getName()); 
     if(i>3) 
      break; 
     i++; 
    } 


    // add popup listener 
    floorsPm.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() { 
     // onClick 
     @Override 
     public boolean onMenuItemClick(MenuItem item){ 
      //  get floorname 

      int flOrder = item.getOrder(); 
      if(flOrder == Menu.NONE) 
       return true; 
      flOrder--; 

      final String floorId = flList.get(flOrder).getMapId(); 

      //  set camera to floor 

      runOnUiThread(new Runnable() { 
       @Override 
       public void run() { 
        floorsPm.dismiss(); 
        mapFragment.getMapManager().setCameraLayer(floorId, false); 
        Log.d(TAG, "post cameraLayer set"); 
        changedSteps = true; 
        pauseNav(); 

       } 
      }); 




      return true; 
     } 

    }); 
    floorsPm.show(); 


}

'ListPopupWindow'由ListView支持，并且根本不提供任何定制。你可以在这里找到（https://github.com/natario1/Autocomplete/blob/master/autocomplete/src/main/java/com/otaliastudios/autocomplete/AutocompletePopup.java）一个可以托管任何视图的弹出窗口。只需调用'setView（view）'而不是'show（）'。 – natario

这是我的例子创建秀ListPopupWindow

首先，创建布局item_list_popup_window为ListPopupWindow

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:background="#e4e4e4" 
    android:paddingTop="1dp" 
    android:orientation="horizontal"> 

    <TextView 
     android:id="@+id/text_title" 
     android:layout_width="0dp" 
     android:layout_height="wrap_content" 
     android:layout_gravity="center" 
     android:layout_weight="1" /> 

    <Button 
     android:id="@+id/button_delete" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="Delete" /> 

</LinearLayout>

二的每个项目，创建Adapter您的ListPopupWindow就像

public class ListPopupWindowAdapter extends BaseAdapter{ 
    private Activity mActivity; 
    private List<String> mDataSource = new ArrayList<>(); 
    private LayoutInflater layoutInflater; 
    private OnClickDeleteButtonListener clickDeleteButtonListener; 

    ListPopupWindowAdapter(Activity activity, List<String> dataSource, @NonNull OnClickDeleteButtonListener clickDeleteButtonListener){ 
     this.mActivity = activity; 
     this.mDataSource = dataSource; 
     layoutInflater = mActivity.getLayoutInflater(); 
     this.clickDeleteButtonListener = clickDeleteButtonListener; 
    } 

    @Override 
    public int getCount() { 
     return mDataSource.size(); 
    } 

    @Override 
    public String getItem(int position) { 
     return mDataSource.get(position); 
    } 

    @Override 
    public long getItemId(int position) { 
     return 0; 
    } 

    @Override 
    public View getView(final int position, View convertView, ViewGroup parent) { 
     ViewHolder holder; 
     if(convertView == null){ 
      holder = new ViewHolder(); 
      convertView = layoutInflater.inflate(R.layout.item_list_popup_window, null); 
      holder.tvTitle = (TextView) convertView.findViewById(R.id.text_title); 
      holder.btnDelete = (Button) convertView.findViewById(R.id.button_delete); 
      convertView.setTag(holder); 
     }else{ 
      holder = (ViewHolder) convertView.getTag(); 
     } 

     // bind data 
     holder.tvTitle.setText(getItem(position)); 
     holder.btnDelete.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       clickDeleteButtonListener.onClickDeleteButton(position); 
      } 
     }); 
     return convertView; 
    } 

    public class ViewHolder{ 
     private TextView tvTitle; 
     private Button btnDelete; 
    } 

    // interface to return callback to activity 
    public interface OnClickDeleteButtonListener{ 
     void onClickDeleteButton(int position); 
    } 
}

三，您创建创建一个函数，并显示ListPopupWindow

private void showListPopupWindow(View anchorView) { 
    final ListPopupWindow listPopupWindow = new ListPopupWindow(this); 
    listPopupWindow.setWidth(600); 
    List<String> sampleData = new ArrayList<>(); 
    sampleData.add("A"); 
    sampleData.add("B"); 
    sampleData.add("CCCCCCCCCCCCCC"); 
    sampleData.add("D"); 
    sampleData.add("EEEEEEEEE"); 

    listPopupWindow.setAnchorView(anchorView); 
    ListPopupWindowAdapter listPopupWindowAdapter = new ListPopupWindowAdapter(this, sampleData, new ListPopupWindowAdapter.OnClickDeleteButtonListener() { 
     @Override 
     public void onClickDeleteButton(int position) { 
      Toast.makeText(MainActivity.this, "Click delete " + position, Toast.LENGTH_SHORT).show(); 
      listPopupWindow.dismiss(); 
     } 
    }); 
    listPopupWindow.setAdapter(listPopupWindowAdapter); 
    listPopupWindow.show(); 
}

最后，您可以显示ListPopupWindow通过

showListPopupWindow(v);

例如，如果你想点击按钮以显示它

anyButton.setOnClickListener(new View.OnClickListener() { 
    @Override 
    public void onClick(View v) { 
     showListPopupWindow(v); 
    } 
});

解决方案看起来不错，将测试出来。你也可以根据我的代码修改它，并告诉我如何修改弹出窗口从左侧滑入？ –

这仍然不是我所寻找的，但是因为你是第一个为你回答50分 –

请试试这个代码，也许你不会喜欢这个

private void floorMenu(ImageView btnFloorMenu){ 
final Dialog customDialog = new Dialog(this); 
customDialog.requestWindowFeature(Window.FEATURE_NO_TITLE); 
customDialog.setContentView(R.layout.item_dialog_coustom_design); 

TextView clickItem = (TextView)customDialog.findViewById(R.id.item_click); 
TextView clickItem1 = (TextView)customDialog.findViewById(R.id.item_click1); 
TextView clickItem2 = (TextView)customDialog.findViewById(R.id.item_click2); 
Button btnClose = (Button)customDialog.findViewById(R.id.btn_close); 

clickItem.setOnClickListener(new View.OnClickListener() { 
    @Override 
    public void onClick(View v) { 
     customDialog.dismiss(); 
     // wright your Button Action 
    } 
}); 

clickItem1.setOnClickListener(new View.OnClickListener() { 
    @Override 
    public void onClick(View v) { 
     customDialog.dismiss(); 
     // wright your Button Action 
    } 
}); 

clickItem2.setOnClickListener(new View.OnClickListener() { 
    @Override 
    public void onClick(View v) { 
     customDialog.dismiss(); 
     // wright your Button Action 
    } 
}); 

btnClose.setOnClickListener(new View.OnClickListener() { 
    @Override 
    public void onClick(View v) { 
     customDialog.dismiss(); 
    } 
}); 
customDialog.show(); 

}

创建的LinearLayout layout_width = “280dp” layout_height = “WRAP_CONTENT” 机器人：方向= “垂直”文件名item_dialog_coustom_design.xml然后把这个代码

<TextView 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:text="Your Title" 
     android:background="#000" 
     android:textColor="#fff" 
     android:padding="12dp" 
     android:textSize="20sp"/> 

    <TextView 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_marginBottom="1dp" 
     android:background="#fff" 
     android:padding="10dp" 
     android:text="Your Item" 
     android:id="@+id/item_click" 
     android:textSize="16sp" /> 

    <TextView 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_marginBottom="1dp" 
     android:background="#fff" 
     android:padding="10dp" 
     android:text="Your Item" 
     android:id="@+id/item_click1" 
     android:textSize="16sp" /> 
    <TextView 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_marginBottom="1dp" 
     android:background="#fff" 
     android:padding="10dp" 
     android:text="Your Item" 
     android:id="@+id/item_click2" 
     android:textSize="16sp" /> 
    <LinearLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:paddingTop="10dp" 
     android:paddingRight="10dp" 
     android:paddingBottom="10dp" 
     android:background="#fff" 
     android:gravity="right"> 
      <Button 
       android:layout_width="wrap_content" 
       android:layout_height="wrap_content" 
       android:id="@+id/btn_close" 
       android:text="Close"/> 
    </LinearLayout>
