How to realize this custom popup menu with Material Design Android?

Question

I want to realize a custom popup menu like Twitter in Android for example with item and picture but I don't know what's the component used for that.

In Material Design website, google present this solution. So I think, there is a native solution to achieve this.

I tried with Popup menu, but I can't find how to customize the layout of this view like that.

Answer 1

you can use a ListPopupWindow, submitting your custom adapter, through which you can control the layout of every single row of the ListPopupWindow. As for a normal PopupWindow you have to provide an anchor view and additionally you have to call setContentWidth on the instance of ListPopupWindow, which sets the width of the popup window by the size of its content. It is a small price you have to pay, but for a small dataset is not a big deal. I have this utility method to retrieve the max width of the row:

public int measureContentWidth(ListAdapter adapter) {
    int maxWidth = 0;
    int count = adapter.getCount();
    final int widthMeasureSpec = MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED);
    final int heightMeasureSpec = MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED);
    View itemView = null;
    for (int i = 0; i < count; i++) {
        itemView = adapter.getView(i, itemView, this);
        itemView.measure(widthMeasureSpec, heightMeasureSpec);
        maxWidth = Math.max(maxWidth, itemView.getMeasuredWidth());
    }
    return maxWidth;
}
