listview嵌套gridview

1.首先要自定义一个继承gridview的类

public class MyGridView extends GridView {public boolean hasScrollBar = true;public MyGridView(Context context) {super(context);}public MyGridView(Context context, AttributeSet attrs) {super(context, attrs);}@Overrideprotected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,MeasureSpec.AT_MOST);super.onMeasure(widthMeasureSpec, expandSpec);}
}

2.在布局中引用这个自定义gridview

<com.example.administrator.tunrb.MyFragment.Single_fragment.MyGridView xmlns:android="http://schemas.android.com/apk/res/android"android:id="@+id/single_gridview"android:layout_width="match_parent"android:layout_height="match_parent"android:columnWidth="80dp"android:background="#ffffff"android:horizontalSpacing="5dp"android:numColumns="auto_fit"android:verticalSpacing="5dp"></com.example.administrator.tunrb.MyFragment.Single_fragment.MyGridView>
