Question

如何在Wear应用中使用Android Wear Wrist Gestures？是否可以检测它们，例如滚动手腕滚动？

Answer 1

如果您在活动中注册了回调onKeyDown()，系统会通知您以下events：KEYCODE_NAVIGATE_NEXT， KEYCODE_NAVIGATE_PREVIOUS，KEYCODE_NAVIGATE_IN和KEYCODE_NAVIGATE_OUT。这些新手势将映射到这些事件。所以这是一个快速覆盖：

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {

    Log.d(TAG, "onKeyDown Keycode: " + keyCode);

    switch (keyCode) {
        case KeyEvent.KEYCODE_NAVIGATE_NEXT:
            // Do something that advances user view to the next item in an ordered list
            return true;
        case KeyEvent.KEYCODE_NAVIGATE_PREVIOUS:
            // Do something that advances user view to the previous item in an ordered list
            return true;
        case KeyEvent.KEYCODE_NAVIGATE_IN:
            // Do something that activates the item that currently has focus or expands to
            // the next level of a navigation hierarchy
            return true;
        case KeyEvent.KEYCODE_NAVIGATE_OUT:
            // Do something that backs out one level of a navigation hierarchy or collapses
            // the item that currently has focus.
            return true;
        default:
            // If you did not handle, then let it be handled by the next possible element as
            // deemed by Activity.
            return super.onKeyDown(keyCode, event);
    }
}

我相信你会发现HandsFree Wear应用程序很有趣（我是创造者），你可以通过手腕手势（几乎）完全使用你的智能手表。
