有人能告诉我在网格视图中实现水平滚动的方法吗？

Answer 1

最后我能够在android中实现水平滚动网格视图......这是代码：

public class HorizontalGridView extends Activity {
    Bitmap viewBgrnd;
    ImageButton img ;
    Button button;
    Button b1[] = new Button[100];
    static int total=0;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        horizontalScrollGalleryLayout();
    }

    public void horizontalScrollGalleryLayout () {
        Integer[] mThumbIds = {
            R.drawable.image0,R.drawable.image1,R.drawable.image2,
            R.drawable.image3,R.drawable.image4,R.drawable.image5,

        HorizontalScrollView sv = new HorizontalScrollView(this);
        LinearLayout llh = new LinearLayout(this);
        llh.setOrientation(LinearLayout.HORIZONTAL);
        LinearLayout.LayoutParams layoutParamsTV = new LinearLayout.LayoutParams(100,100);
        LinearLayout.LayoutParams layoutParamsLL = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
        LinearLayout.LayoutParams layoutParamsLLD = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.FILL_PARENT);

        for(int k=0;k<mThumbIds.length;k++)
        {   
            LinearLayout llv = new LinearLayout(this);
            for (int i=0; i<4; i++) {
                llv.setOrientation(LinearLayout.VERTICAL);
                button = new Button(this);
                try {
                    button.setBackgroundResource(mThumbIds[total]);
                    total++;
                } catch (Exception e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }

                llv.addView(button, layoutParamsTV);
                //b1[k].setBackgroundResource(mThumbIds[k]);
            }

            //llv.addView(button, layoutParamsTV);
            llh.addView(llv, layoutParamsLL);
