添加到OnGestureListener按钮？ [英] Add OnGestureListener to Button?

问题描述

我试图找出如何添加OnGestureListener或一些其他的方式来检测在屏幕上触摸拖动到一个按钮，或可添加到浏览其他一些部件。我一直在试图找出如何一会儿做到这一点，我不能。我已经看到了，并成功地能够把它做的活动。任何人都可以拼出了这一点对我来说，因为我似乎遇到了不少的麻烦，比我以为我会与此有关。谢谢你。

I'm trying to figure out how to add an OnGestureListener or some other way to detect a touch drag across the screen to a button, or some other widget that can be added to a View. I've been trying to figure out how to do this for a while and I can't. I've seen and successfully been able to do it to an activity. Can anyone spell this out for me, because I seem to be having a lot more trouble than I thought I would with this. Thanks.

推荐答案

我假设你已经通过的 http://developer.android.com/resources/articles/gestures.html 。诀窍在于，你可以有 GestureOverlayView 作为另一查看上面的透明层。然后，您可以跨preT任何手势检测为属于底层查看。

I'm assuming you've already gone through http://developer.android.com/resources/articles/gestures.html. The trick is that you can have the GestureOverlayView as a transparent layer on top of another View. You can then interpret any gestures detected as belonging to the underlying View.

在文章中，他们表现出你这样的布局：

In the article, they show you a layout like this:

<android.gesture.GestureOverlayView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/gestures"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"

    android:gestureStrokeType="multiple"
    android:eventsInterceptionEnabled="true"
    android:orientation="vertical">

    <ListView
        android:id="@android:id/list"  
        android:layout_width="fill_parent" 
        android:layout_height="fill_parent"  />

</android.gesture.GestureOverlayView>

然后检测可以PTED从ListView控件来间$ P $任何手势。在你的情况你的按钮替换ListView的，你应该准备就绪。

Any gestures detected could then be interpreted as coming from the ListView. In your case replace the ListView with your Button, and you should be all set.
