机顶盒上gridview+ScrollView的使用。

android:descendantFocusability="afterDescendants"

<ScrollView
        android:id="@+id/scroll_content"
        android:layout_width="1740.0px"
        android:layout_height="600.0px"
        android:layout_x="81.0px"
        android:layout_y="258.0px" >

        <com.hysmarthotel.view.MyGridView
            android:id="@+id/lightview"
            android:layout_width="match_parent"
               android:layout_height="match_parent"
            android:descendantFocusability="afterDescendants"
            android:horizontalSpacing="58dp"
            android:numColumns="4"
            android:scrollbars="none"
            android:stretchMode="columnWidth"
            android:verticalSpacing="80dp" />
    </ScrollView>

package com.hysmarthotel.view;

import android.content.Context;
import android.util.AttributeSet;
import android.widget.GridView;

public class MyGridView extends GridView { 

    public MyGridView(Context context, AttributeSet attrs) { 
        super(context, attrs); 
    } 

    public MyGridView(Context context) {

        int expandSpec = MeasureSpec.makeMeasureSpec(
