Answer 1

you can try this, i've tried so many ways, but none of them meet my needs, and then i tried to do it myself, and i succeed , and it seems good , it's smooth.

public class WrapContentListView extends ListView{
public WrapContentListView(Context context) {
    super(context);
}

public WrapContentListView(Context context, AttributeSet attrs) {
    super(context, attrs);
}

public WrapContentListView(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
}


@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,MeasureSpec.AT_MOST);
    super.onMeasure(widthMeasureSpec, expandSpec);
}
}
