我使用 GridView 让它工作了！

下面是我的代码：

片段1.java：

public class Fragment1 extends Fragment {

public static final String ARG_SECTION_NUMBER = "section_number";

public Fragment1() {
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.fragment_1, container, false);

    GridView gridView = (GridView) rootView.findViewById(R.id.gridview_numbers);
    gridView.setAdapter(new TextViewAdapter(getActivity()));

    gridView.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
           Toast.makeText(getActivity(), ((TextView) v).getText(), Toast.LENGTH_SHORT).show();
        }
    });

    return rootView;
}

}

TextViewAdapter.java：

public class TextViewAdapter extends BaseAdapter {
private Context mContext;

public TextViewAdapter(Context c) {
    mContext = c;
}

public int getCount() {
    return mThumbIds.length;
}

public Object getItem(int position) {
    return null;
}

public long getItemId(int position) {
    return 0;
}

public View getView(int position, View convertView, ViewGroup parent) {

    TextView textView;

    if(convertView == null)
    {
        textView = new TextView(mContext);
        textView.setLayoutParams(new GridView.LayoutParams(65, 85));
        textView.setTextSize(18.0f);
        textView.setGravity(0x11);
    } 
    else
    {
        textView = (TextView) convertView;
    }

    textView.setBackgroundResource(mThumbIds[position]);
    textView.setText(Integer.toString(position + 1));

    return textView;
}

// references to our images
private Integer[] mThumbIds = {
    R.drawable.number_deselect, R.drawable.number_deselect, R.drawable.number_deselect,
