java - 如何在android wear中实现手势识别

Question

你好，我正在寻找如何在 android wear 中检测手势，在 android 中我使用了一些这样的代码，但在 android wear 中不起作用..有没有办法覆盖默认手势 Action 或只是识别它们？

我做的就像谷歌开发者: https://www.youtube.com/watch?v=naf_WbtFAlY http://youtu.be/sha_w3_5c2c?t=25m1s 模拟器有问题吗？ (我使用的是 32 位模拟器: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);
    }


}

我想左右滑动，上下滚动手势:

解决了!检查我的答案..

一天后我让它开始工作，丢失的部分是我必须禁用滑动关闭手势并将 DismissOverlayView 添加到我的布局，步骤:

1. 禁用滑动关闭手势 将 AppTheme 样式添加到您的 styles.xml 并将其用作您的 mainfest 中的应用程序样式

样式.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 添加到您的主布局

       <android.support.wearable.view.DismissOverlayView 
       android:id="@+id/dismiss_overlay"
       android:layout_height="match_parent"
       android:layout_width="match_parent"/>
   

2. 像这样在您的 Activity 中使用它来获取手势

       public class WearActivity extends Activity {
       private DismissOverlayView mDismissOverlay;
       private GestureDetector mDetector;
   
       public void onCreate(Bundle savedState) {
           super.onCreate(savedState);
           setContentView(R.layout.wear_activity);
   
           // Obtain the DismissOverlayView element
           mDismissOverlay = (DismissOverlayView) findViewById(R.id.dismiss_overlay);
           mDismissOverlay.setIntroText(R.string.long_press_intro);
           mDismissOverlay.showIntroIfNecessary();
   
           // Configure a gesture detector
           mDetector = new GestureDetector(this, new 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;
           }
           });
       }
   
       // Capture long presses
       @Override
       public boolean onTouchEvent(MotionEvent ev) {
           return mDetector.onTouchEvent(ev) || super.onTouchEvent(ev);
       } 
       }
