如何在android穿戴中实现手势识别

Question

你好，我在寻找如何检测android穿戴中的手势，在android中，我使用这样的代码，但在android穿戴中不起作用。是否有一种方法可以覆盖默认的手势动作或只识别它们？

我就像google开发者一样：WbtFAlY，5c2c?t=25m1s，仿真器有什么问题吗？(我使用32位仿真器：emulator -avd AndroidWearXC -force-32bit)

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.GestureDetector;
import android.view.MotionEvent;


public class MainActivity extends Activity {
    private GestureDetector mDetector;

    private static String DEBUG_TAG="MainActivity";
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        mDetector = new GestureDetector(this, new GestureDetector.SimpleOnGestureListener() {

            @Override
            public void onLongPress(MotionEvent event) {

                Log.d(DEBUG_TAG, " onLongPress: " + event.toString());
            }

            @Override
            public boolean onDown(MotionEvent event) {
                Log.d(DEBUG_TAG," onDown: " + event.toString());
                return true;
            }

            @Override
            public boolean onFling(MotionEvent event1, MotionEvent event2,
                                   float velocityX, float velocityY) {
                Log.d(DEBUG_TAG, " onFling: " + event1.toString()+event2.toString());
                return true;
            }

            @Override
            public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX,
                                    float distanceY) {
                Log.d(DEBUG_TAG, " onScroll: " + e1.toString()+e2.toString());
                return true;
            }

            @Override
            public void onShowPress(MotionEvent event) {
                Log.d(DEBUG_TAG, " onShowPress: " + event.toString());
            }

            @Override
            public boolean onSingleTapUp(MotionEvent event) {
                Log.d(DEBUG_TAG, " onSingleTapUp: " + event.toString());
                return true;
            }

            @Override
            public boolean onDoubleTap(MotionEvent event) {
                Log.d(DEBUG_TAG, " onDoubleTap: " + event.toString());
                return true;
            }

            @Override
            public boolean onDoubleTapEvent(MotionEvent event) {
                Log.d(DEBUG_TAG, " onDoubleTapEvent: " + event.toString());
                return true;
            }

            @Override
            public boolean onSingleTapConfirmed(MotionEvent event) {
                Log.d(DEBUG_TAG, " onSingleTapConfirmed: " + event.toString());
                return true;
            }
        });

    }
    @Override
    public boolean onTouchEvent(MotionEvent ev) {
        return mDetector.onTouchEvent(ev)  || super.onTouchEvent(ev);
    }


}

我想要左右滑动，滚动upp和向下的手势：

有一天，我开始工作了，失去的部分是，我必须禁用滑动-解散手势，并将DismissOverlayView添加到我的布局中，步骤：

1. 禁用闪避手势，将AppTheme样式添加到styles.xml中，并将其作为应用程序样式在您的主机上使用。

styles.xml：

    <style name="AppTheme" parent="Theme.DeviceDefault">
    <item name="android:windowSwipeToDismiss">false</item>
    </style>

AndroidManifest.xml：

    <application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

1. 将DissmissOverlayView添加到主布局中
2. 在你的活动中用它来获得手势 公共类WearActivity扩展活动{ private DismissOverlayView mDismissOverlay；private GestureDetector mDetector；public void onCreate(Bundle savedState) { super.onCreate(savedState)；setContentView(R.layout.wear_activity)；//获取DismissOverlayView元素mDismissOverlay = (DismissOverlayView) findViewById(R.id.dismiss_overlay)；//配置一个手势检测器mDetector =新的GestureDetector(this，新的SimpleOnGestureListener() {新的SimpleOnGestureListener(@SimpleOnGestureListener()){MotionEvent事件){ Log.d(DEBUG_TAG，“onLongPress：”+ event.toString())；}@重写公共布尔值onDown(MotionEvent事件){ Log.d(DEBUG_TAG，“onDown：+event.toString()”)；返回真；}@覆盖公共布尔值onFling(MotionEvent event1，MotionEvent event2，float velocityX，float velocityY) { Log.d(DEBUG_TAG，“onFling：”+ event1.toString()+event2.toString())；返回true；}@重写公共布尔onScroll(MotionEvent e1，MotionEvent e2，float distanceX，float distanceY) { Log.d(DEBUG_TAG，“onScroll：”+e1.toString()+e2.toString()；返回true；}@重写公共void onShowPress(MotionEvent事件){ Log.d(DEBUG_TAG，“onShowPress：”+ event.toString())；}@重写公共布尔值onSingleTapUp(MotionEvent事件){ Log.d(DEBUG_TAG，“onSingleTapUp：+event.toString()”)；返回true；}@重写公共布尔值onDoubleTap(MotionEvent事件){ Log.d(DEBUG_TAG，“onDoubleTap：”+event.toString()；返回event.toString()；}@重写公共布尔值onDoubleTapEvent(MotionEvent事件)){ Log.d(DEBUG_TAG，“onDoubleTapEvent：”+event.toString()；返回真)；}@覆盖公共布尔值onSingleTapConfirmed(MotionEvent事件){ Log.d(DEBUG_TAG，“onSingleTapConfirmed：”+event.toString()；返回true；})；} //捕获长按压@重写公共布尔值onTouchEvent(MotionEvent ev) {返回mDetector.onTouchEvent(ev) \}

你查过密码了吗？效果很好。对于简单的操作，您可以使用SimpleOnGestureListener来启动工作(它也适用于Android磨损)：

    GestureDetector mDetector;
    mDetector = new GestureDetector(this, new SimpleOnGestureListener() {

        //http://developer.android.com/reference/android/view/GestureDetector.SimpleOnGestureListener.html
//For example:
                public void onLongPress(MotionEvent ev) {
                    //TODO handle your action
                }
            });

        @Override
        public boolean onTouchEvent(MotionEvent ev) {
            return mDetector.onTouchEvent(ev) || super.onTouchEvent(ev);
        }
