ScrollView嵌套GridView的解决办法

 前些日子在开发中用到了需要ScrollView嵌套GridView的情况，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 
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); 
    } 
} 
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。 

XML布局代码 

<ScrollView Android:layout_height="wrap_content" 
        Android:layout_width="fill_parent" android:id="@+id/scroll_content"> 
        <com.yourclass.MyGridView xmlns:Android="http://schemas./apk/res/android" 
            Android:id="@+id/grid_view" android:layout_width="fill_parent" 
            Android:layout_height="wrap_content" android:numColumns="auto_fit" 
            Android:horizontalSpacing="1dip" android:verticalSpacing="1dip" 
            Android:columnWidth="150dip" android:stretchMode="columnWidth" 
            Android:gravity="center"> 
             
        </com.yourclass.MyGridView> 
    </ScrollView> 

Java调用代码 

MyGridView gridview = (MyGridView) findViewById(R.id.grid_view); 
gridview.setAdapter(new ImageAdapter(this));
