android listview display all available items without scroll with static header

Question

I\'m having a little difficulties while trying to get a certain layout to work: I want to have list. List does not have to be scrollable, but should be shown completely. But

Answer 1

I don't have a static header, but using HussoM's post as a clue, here is what I was able to get to work. In my scenario, the height of the items in the list was non-uniform, due to variable text sentences in each of the items, and I am using wrap_content for the height and match_parent for the width.

public class NonScrollableListView extends ListView {

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

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

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

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

  /**
   * Measure the height of all the items in the list and set that to be the height of this
   * view, so it appears as full size and doesn't need to scroll.
   * @param widthMeasureSpec
   * @param heightMeasureSpec
   */
  @Override
  public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
      ListAdapter adapter = this.getAdapter();
      if (adapter == null) {
          // we don't have an adapter yet, so probably initializing.
          super.onMeasure(widthMeasureSpec, heightMeasureSpec);
          return;
      }

      int totalHeight = 0;

      // compute the height of all the items
      int itemCount = adapter.getCount();
      for (int index=0; index 0) {
          totalHeight += this.getDividerHeight() * Math.max(0, itemCount - 1);
      }

      // make it so
      this.setMeasuredDimension(widthMeasureSpec,
              MeasureSpec.makeMeasureSpec(totalHeight, MeasureSpec.EXACTLY));
  }

}
