银河S4浮动触摸

问题描述

三星Galaxy S4有的浮动触摸的功能，其中即使屏幕没有触摸手指可以被检测到。

Samsung Galaxy S4 have the "Floating Touch" functionality, in which the finger can be detected even if the screen is not touched.

我想触发一个事件上的一个按钮（BTN1）当手指通过悬停它。

I would like to fire an event on a button (btn1) when the finger is passing hover it.

我尝试使用OnHoverListener，但onHover从来没有被调用时，MotionEvent是MotionEvent.ACTION_HOVER_ENTER或MotionEvent.ACTION_HOVER_EXIT或MotionEvent.ACTION_HOVER_MOVE，这是我需要的事件。

I tried using the OnHoverListener, but "onHover" never get called when the MotionEvent is MotionEvent.ACTION_HOVER_ENTER or MotionEvent.ACTION_HOVER_EXIT or MotionEvent.ACTION_HOVER_MOVE, which are the event that I need.

这是我的code：

btn1.setOnHoverListener(new OnHoverListener() {
@Override
public boolean onHover(View v, MotionEvent event) {
    Log.d("FloatingTouch", "onHover: "+event.getAction());
    switch (event.getAction()) {
      case MotionEvent.ACTION_HOVER_ENTER:
          Log.d("FloatingTouch", "ACTION_HOVER_ENTER" );
          return true;
      case MotionEvent.ACTION_HOVER_MOVE:
          Log.d("FloatingTouch", "ACTION_HOVER_MOVE" );
          return true;
      case MotionEvent.ACTION_HOVER_EXIT:
          Log.d("FloatingTouch", "ACTION_HOVER_EXIT" );
          break;
      default:
          break;
    }
    return false;
}
});

难道我错过了什么？也许一些权限？

Do I miss something? Maybe some permission?

推荐答案

好了，我终于得到它！

OK, I finally got it!

要使它工作，你必须：

To make it work you have to:

1. 添加一个新的意图过滤器来com.sec.android.airview.HOVER您在清单活动：

1. Add a new intent filter to com.sec.android.airview.HOVER for your Activity in the manifest:

添加onHoverListener你查看

Add an onHoverListener to you View

convertView.setOnHoverListener（新OnHoverListener（）{    @覆盖    公共布尔onHover（视图V，MotionEvent事件）{        Log.d（ListAdapter，哈弗+项目）;        返回false;    }}）;

convertView.setOnHoverListener(new OnHoverListener() { @Override public boolean onHover(View v, MotionEvent event) { Log.d("ListAdapter", "Hover: " + item); return false; }});

它将作品。
