Question

我的网格包含七行五ImageView个。我想将图像置于视图中心。我已经尝试将xml中的每个布局，重力和foregroundGravity属性设置为居中，但似乎没有任何内容。我阅读了一些stackoverflow帖子，他们都建议做我已经尝试过的事情。

网格比右侧更靠近左侧，当我触摸图像时，突出显示的区域在图像右侧比左侧有更多空间。

有关如何让他们居中的任何建议吗？

这是我的布局文件：

  <ImageView
    android:id="@+id/grid_image"
    android:layout_width="50dp"
    android:layout_height="50dp"
    android:layout_gravity="center"
    android:foregroundGravity="center"
  >
  </ImageView>
</LinearLayout>

这是我在以下课程中使用的课程：

class CustomGrid extends BaseAdapter {
  private Context context;
  private final List<Button> buttons;

  CustomGrid(Context c, List<Button> buttons) {
    context = c;
    this.buttons = buttons;
  }

  @Override
  public int getCount() { return buttons.size(); }

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

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

  @Override
  public View getView(int position, View convertView, ViewGroup parent) {
    View grid;
    LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    if (convertView == null) {
      grid = inflater.inflate(R.layout.grid_single, null);

      ImageView imageView = (ImageView) grid.findViewById(R.id.grid_image);
      imageView.setImageResource(buttons.get(position).getBasicImageId());
      buttons.get(position).setImageView(imageView);
    }
    else {
      grid = convertView;
    }

    return grid;
  }
}

这就是图像。目前我只使用Android图片。
