public class MyListView extends ListView{ public MyListView(Context context, AttributeSet attrs) {        super(context, attrs);    }    public MyListView(Context context) {        super(context);    }    public MyListView(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);    }}

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);    }}

 

PS:ScrollView 嵌套 ListView 只显示了一行，有一种动态重设ListView高度的方法，但还会遮住一部分，在这里采用一个自定义的组件继承于原来的类，重写onMeasure方法重绘组件，然后替换布局文件中ListView布局即可。
