如何禁用背后视图点击事件Framelayout [英] How to disable behind view click event Framelayout
本文介绍了如何禁用背后视图点击事件Framelayout的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
这里我有一个视图寻呼机活动，它有一个图像视图和 2 个覆盖栏.我使用 android xml 文件布局本身制作了覆盖栏.
这里我的要求是这样的
1) 第一次单击查看寻呼机的图像视图 = 显示顶部和底部矩形覆盖栏.2) 第二次单击查看寻呼机的图像视图 = 隐藏这些叠加层.
这两个都是类似android画廊视图类型的功能.
但是，当这些顶部和底部布局栏显示时，我只想使用按钮单击仅在此布局中声明的按钮.
但我没有成功实现这件事.
问题
1) 当 top 或 bottom bar 存在时，如果我可以单击 next 或 previous 按钮，而不是它在 imageview 单击单击事件后面的事件，以及我的栏越来越看不见了.2) 只想声明按钮事件3) 当我触摸覆盖栏时，避免点击 imageview.
简而言之，当我的顶部和底部图像栏出现时，顶部和底部图像栏的图像视图不会发生任何 touh 事件.当我点击下一个或上一个或共享按钮时，我可以点击 imageview 但无法点击.
所以这些是我面临的问题，请帮助我.
源代码:
activity_pager_image.xml
<?xml version="1.0" encoding="utf-8"?><FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent" >谢谢
解决方案 imageView.setSingleTapListener(new OnImageViewTouchSingleTapListener() {@覆盖公共无效 onSingleTapConfirmed() {Log.d("TAG", "setSingleTapListener");s计数器++；如果(sCounter % 2 == 0){mRlTopOverlayBar.setVisibility(View.GONE);mRlBottomOverlayBar.setVisibility(View.GONE);pager.requestFocus();} 别的 {mRlTopOverlayBar.setVisibility(View.VISIBLE);mRlBottomOverlayBar.setVisibility(View.VISIBLE);mRlTopOverlayBar.requestFocus();mRlBottomOverlayBar.requestFocus();mRlBottomOverlayBar.setClickable(true);mRlTopOverlayBar.setClickable(true);}}});
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.
Here my requirement is like that
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.
These both are functions like android gallary view type.
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.
But I am not getting success to achieve this thing.
Problems
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.
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.
So these are the problems which i am facing, Please help me .
