Android: wrap_content is not working with ListView

Question

I am working on android. I want my list view to wrap its content horizontally and not to fill all the width. The wrap_content properties is not working. What to do?

Answer 1

In order achieve wrap_content height in ListView, we need to use CustomListView that extends our native ListView.

MyListView.java

public class MyListView extends ListView {

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

    public MyListView(Context context) {
        super(context);
    }

    public MyListView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

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

}

in your layout use custom view like this,

layout.xml

<com.yourpackagename.MyListView
        ...       
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        ... />
