如何禁用视图后单击事件Framelayout [英] How to disable behind view click event Framelayout

问题描述

在这里，我有一个视图寻呼机活动，其中有一个imageview和2个叠加条.我使用android xml文件布局本身制作了覆盖栏.

Here i have one view pager activity which has one imageview and 2 overlay bars. there overlay bars i made using android xml file layout itself.

我的要求就是这样

1)第一次单击查看寻呼机的imageview =显示顶部和底部矩形叠加条. 2)第二次点击查看分页器的imageview =隐藏这些叠加层.

1) single tap on view pager's imageview first time = show top and bottom rectangle overlaybar. 2) single tap on view pager's imageview second time = hide these overlays.

这两个功能都类似于android gallary view type.

These both are functions like android gallary view type.

但是，当此时显示这些顶部和底部布局栏时，我只想使用按钮，请仅单击在此布局中声明了哪些按钮.

But here when these top and bottom layout bar displays at that time i want to use only buttons click only which buttons are declare within this layout.

但是我没有成功实现这一目标.

But I am not getting success to achieve this thing.

问题

1)如果top or bottom bar在那，如果我可以单击next or previous按钮，则它比imageview单点触摸事件背后的需要事件多，而我的栏变得不可见. 2)只想声明按钮事件 3)避免在我触摸覆盖栏时单击imageview.

1) when top or bottom bar is there if i can click on next or previous button than its takes event for behind imageview single tap touch event, And my bar is getting invisible. 2) Only wants declare buttons event only 3) Avoid imageview getting clicked when i touch to overlay bar.

简而言之，当那时我的顶部和底部图像栏出现时，不会发生来自顶部和底部图像栏的imageview的touh事件.我可以单击imageview，但实际上单击下一个或上一个或共享按钮时却无法单击.

In short when my top and bottom image bar appears at that time no touh event takes place for imageview from top and bottom image bar. I can click on imageview but not making clickable when i click on actually next or previous or share button.

这些就是我面临的问题，请帮助我.

So these are the problems which i am facing, Please help me .
