android ExpandableListView中的child是一个Gridview

Question

android ExpandableListView中的child是一个Gridview，但是GridView只能显示一行，怎么呢设置

Answer 1

我跟你的相反，GridView嵌套ListView

import android.content.Context;
import android.util.AttributeSet;
import android.widget.ListView;

public class ChildListView extends ListView {

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

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

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

    @Override
    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

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

關鍵是onMeasure方法，
你可以將ListView改為GridView，其他不變
