银河S4浮动触摸 [英] Floating Touch on Galaxy S4

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。
