android自动计算高度的listview 嵌套在ScrollView中使用

自动计算listview的高度 返回最大高度

public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {


        int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,  
                MeasureSpec.AT_MOST);  
        super.onMeasure(widthMeasureSpec, expandSpec);  


    }

其余部分不需要改动

public class MylistView extends ListView {

    public MylistView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        // TODO Auto-generated constructor stub
    }
    public MylistView(Context context, AttributeSet attrs) {
        super(context, attrs);
        // TODO Auto-generated constructor stub
    }
    public MylistView(Context context) {
        super(context);
        // TODO Auto-generated constructor stub
    }

    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {


        int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,  
                MeasureSpec.AT_MOST);  
        super.onMeasure(widthMeasureSpec, expandSpec);  


    }
}

GridView同理

public class MyGridview extends GridView {

public MyGridview(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        // TODO Auto-generated constructor stub
    }

public MyGridview(Context context, AttributeSet attrs) {
        super(context, attrs);
        // TODO Auto-generated constructor stub
    }

    public MyGridview(Context context) {
        super(context);
        // TODO Auto-generated constructor stub
    }

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

可在ScrollView中或其他自定义可滚动view中使用
