ScrollView嵌套GridView或ListView,由于这两款控件都自带滚动条,当他们碰到一起的时候便会出问题,即GridView会显示不全。
解决办法:自定义一个GridView控件
package cn.com.gxlu.frame.impl; import android.content.Context; import android.util.AttributeSet; import android.widget.GridView; public class MyGrideView extends GridView { public MyGrideView(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } public MyGrideView(Context context, AttributeSet attrs) { super(context, attrs); } public MyGrideView(Context context) { super(context); } @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST); super.onMeasure(widthMeasureSpec, expandSpec); } }
该自定义控件只是重写了GridView的onMeasure方法,使其不会出现滚动条,ScrollView嵌套ListView也是同样的道理,不再赘述。
