小编f.t*_*ski的帖子

我正在以水平方向的线性布局创建动态图像。我在用：

ImageView imageView = new ImageView(getContext());
            imageView.setLayoutParams(new 
android.view.ViewGroup.LayoutParams(200,200));
            imageView.setOnTouchListener(new MyTouchListener());
            imageView.setOnDragListener(new MyDragListener());
            setImageIcon(imageView, ap.getPackageName());
            topLayout.addView(imageView);

但在屏幕的末尾，它继续在右侧无限添加图标。我想添加边框并从新行开始。有什么选项可以做到这一点吗？这是我的 xml：
