ScrollView嵌套ListView,ListView高度自适应

之前做过一个项目，是ScrollView包含GridView和ListView,其中ListView和GridView无法自适应高度，研究了一下，需要重写onMeasure方法，ListView和GridView一样，废话不多说看源码：

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

public class AdaptiveListView extends ListView {

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

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

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

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