Question

在此处输入代码＆gt;这里在onClick am创建一个包含一些子视图的动态视图（New cutLayout）。＆GT;

1）工作：设置随机生成的ID（cutlayout ID）。

2）工作：设置onTouchListener（cutlayout拖动）。

3） 问题：为每个（cutlayout）设置onSeekListener，它的工作，但仅适用于最近创建的cutlayout。 （即点击4次我创建了4个cutLayouts，现在onSeekListener仅适用于最近创建的第4个cutlayout）

我正在尝试这样做：当我触摸（第1或第2或第50个cutlayout）时，onSeekListener应仅适用于相关的cutlayout。

getId只存储一个最近创建的ID。有人请帮忙。

                                    lastAction = MotionEvent.ACTION_MOVE;

                                    break;

                                default:

                    rL.addView(cutLayout);
            }
        });


    }

    @Override
    public int getItemCount() {
        return this.selectedImageModels2.size();
    }

}
