解决ScrollView 嵌套 GridView 单行显示问题

 

简单重写GridView

package com.hh.beauter.my_ui;

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

/**
 * Created by Hh。 on 2016/12/14.
 */


public class MyGridView extends GridView {
    public MyGridView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

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

    public MyGridView(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);
    }
}

　　重写之后加载页面ScrollView可能不显示在最顶端

　　只需

scrollView.smoothScrollTo(0,20);

　　即可
