Question

你好我正在寻找如何在android中检测手势，在android中我使用了一些这样的代码，但是在android中没有用..有没有办法覆盖默认的手势动作或只是识别它们？

我就像谷歌开发者一样： 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);
    }


}

我想要左右滑动，然后滚动upp和down手势： enter image description here

解决！检查我的答案..

一天后我开始工作，丢失的部分是我必须禁用Swipe-To-Dismiss Gesture并将DismissOverlayView添加到我的布局，步骤：

禁用“滑动到解除”手势将AppTheme样式添加到styles.xml并在mainfest中将其用作app风格

styles.xml：

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

的AndroidManifest.xml：

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

将DissmissOverlayView添加到主布局

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

在此类活动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);
    } 
    }

你检查过代码了吗？它工作正常。对于简单的操作，可以使用SimpleOnGestureListener来实现工作（它也适用于Android Wear）：

    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);
        }
