列表：完全展開的列表

完全展開的ListView

public class ExpandingListView  extends ListView {

    public ExpandingListView(Context context) {
        super(context);
        // TODO Auto-generated constructor stub
    }

    public ExpandingListView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        // TODO Auto-generated constructor stub
    }

    public ExpandingListView(Context context, AttributeSet attrs) {
        super(context, attrs);
        // TODO Auto-generated constructor stub
    }

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

}

完全展開的GridView

/**
 * 完全展開的gridview 即不折疊，使用時建議父級容器足夠高，或者可以滑動
 */
public class ExpandingGridView extends GridView {

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

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

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