ScrollView嵌套ListView,ListView高度自适應

之前做過一個項目，是ScrollView包含GridView和ListView,其中ListView和GridView無法自适應高度，研究了一下，需要重寫onMeasure方法，ListView和GridView一樣，廢話不多說看源碼：

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);

}

}
