Android学习之——如何将GridView内嵌在ScrollView中

 1 <ScrollView
 2         android:layout_width="match_parent"
 3         android:layout_height="0dp"
 4         android:layout_weight="5.5">
 5         <GridView
 6             android:id="@+id/gridView"
 7             android:layout_width="fill_parent"
 8             android:layout_height="fill_parent"
 9             android:numColumns="auto_fit"
10             android:columnWidth="90dp"
11             android:gravity="center"
12             android:listSelector="@drawable/base_item_selector"
13             android:stretchMode="columnWidth"
14             ></GridView>
15       </ScrollView>
16     <RelativeLayout

1 mGridView = (GridView)findViewById(R.id.gridView);
2           ArrayAdapter adapter = new ArrayAdapter(this,android.R.layout.simple_list_item_1,
3                   letters);
4           mGridView.setAdapter(adapter);

 1 public class MyGridView extends GridView {
 2     public MyGridView(Context context, AttributeSet attrs) {
