适用于Android的Bidircetional滚动条

这更像是一个质量答案而不是一个问题,我只是不知道如何发布它,主持人如果你能告诉我是否有这样的事情.

这个问题被要求死亡,然后我需要做类似的事情,所以我解决了这个问题.这篇文章的答案是如何在android中创建一个3×3双向滚动视图

最佳答案 以下是如何创建双向滚动视图

将一个库放入一个GridView中,其中一列和一列的大小设置为填充父视图(或某些效果).将一个库放入GridView,并将其在LayoutParams中的高度设置为您想要占用它们的drawable / views的高度.您需要做的就是移动一个图库以在网格视图中移动所有其他图库.我将在下面发布代码.注意:我所做的代码是对概念的测试,我只是在手机上尝试过.因此,它并不浮华.当我继续研究它时,我可能会更新代码以使其看起来更好.

这是对以下问题的一般回答:
How to make a 2-dimension image gallery with both horizontal and vertical scrolling?

GridView with horizontal scroll

public class Test extends Activity {
/** Called when the activity is first created. */
GridView gv;
Gallery g[] = new Gallery[3];
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    gv = (GridView)findViewById(R.id.gridview);
    gv.setAdapter(new GAdapter());
    for (int i = 0; i < g.length; i++) {
        g[i] = new Gallery(this);
        g[i].setAdapter(new GGAdapter());
        g[i].setOnTouchListener(new OnTouchListener() {
            @Override public boolean onTouch(View arg0, MotionEvent ev) {
                if (ev.getAction() == MotionEvent.ACTION_UP) {
                    for (int j = 0; j < g.length; j++) {
                        g[j].setSelection(((AdapterView)arg0).getSelectedItemPosition());
                    }
                }
                return false;
            }
        });
    } 
}

private class GAdapter extends BaseAdapter {    
    public GAdapter() {}
    @Override public int getCount() {return g.length;}
    @Override public Object getItem(int pos) {return pos;}
    @Override public long getItemId(int pos) {return pos;}
    @Override public View getView(final int pos, View convertView, ViewGroup parent) {

        g[pos].setLayoutParams(new GridView.LayoutParams(gv.getWidth(), gv.getHeight()));           
        return g[pos];
    }
}

private class GGAdapter extends BaseAdapter {       
    int[] images = new int[] {R.drawable.icon,
            R.drawable.icon,
            R.drawable.icon};
    public GGAdapter() {}
    @Override public int getCount() {return images.length;}
    @Override public Object getItem(int pos) {return pos;}
    @Override public long getItemId(int pos) {return pos;}
    @Override public View getView(final int pos, View convertView, ViewGroup parent) {
        ImageView mIV = new ImageView(Test.this);
        mIV.setBackgroundResource(images[pos]);
        mIV.setLayoutParams(new Gallery.LayoutParams(gv.getWidth(), gv.getHeight()/3));         
        return mIV;
    }
}

}

和我的xml文件:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<GridView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/gridview"
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    android:numColumns="1"
    android:verticalSpacing="10dp"
    android:horizontalSpacing="10dp"
    android:gravity="center"/>
 </LinearLayout>
