Cocos2d-x3.2中添加Android手机震动

1、在proj.android这个目录下



AndroidManifest.xml 文件，给app 增加震动权限

<uses-permission android : name = "android.permission.VIBRATE" />



2、 修改android 项目源文件src/org/cocos2dx/lib/Cocos2dxSound.java增加震动方法，调用android底层振动器

/*** @param time 震动时间 */

public void vibrate( long time) {

Vibratorv = (Vibrator) mContext .getSystemService(Context. VIBRATOR_SERVICE);

v.vibrate(time);

}

/** * @param pattern 震动时间数组 EG:{500,200,500,300}* @param repeat 重复次数 */

public void vibrateWithPattern( long [] pattern, int repeat) {

Vibratorv = (Vibrator) mContext .getSystemService(Context. VIBRATOR_SERVICE);

v.vibrate(pattern,repeat);

}

/*** 取消震动 */

public void cancelVibrate() {

Vibratorv = (Vibrator) mContext .getSystemService(Context. VIBRATOR_SERVICE);

v.cancel();

}

3. 至此，java 项目中的修改就OK啦，下面就是在Cocos2d-x中增加JNI方法让C++去掉用Java的震动方法就OK啦!

3.1. 修改 libCocosDenshion 项目中cocos2d-x\CocosDenshion\android\jni文件夹下的SimpleAudioEngineJni.h和SimpleAudioEngineJni.cpp方法

在SimpleAudioEngineJni.h 中添加

#ifndef __SIMPLE_AUDIO_ENGINE_JNI__

#define __SIMPLE_AUDIO_ENGINE_JNI__

#include

extern "C"

{

......

// add thesementhod

extern void vibrateJNI(long long time);

extern void vibrateWithPatternJNI(long long pattern[], intrepeat);

extern void cancelVibrateJNI();

}

#endif // __SIMPLE_AUDIO_ENGINE_JNI__

在SimpleAudioEngineJni.cpp 中添加

// add these jni menthod

void vibrateJNI(long long time)

{

JniMethodInfomethodInfo;

if (! getStaticMethodInfo(methodInfo, "vibrate", "(J)V"))

{

return;

}

methodInfo.env->CallStaticVoidMethod(methodInfo.classID, methodInfo.methodID, time);

methodInfo.env->DeleteLocalRef(methodInfo.classID);

}

void vibrateWithPatternJNI(long long pattern[], int repeat)

{

JniMethodInfomethodInfo;

if (! getStaticMethodInfo(methodInfo, "vibrateWithPattern", "([JI)V"))

{

return;

}

int elements = sizeof(pattern);

jlongArrayjLongArray = methodInfo.env->NewLongArray(elements);

methodInfo.env->SetLongArrayRegion(jLongArray, 0, elements, (jlong*) pattern);

methodInfo.env->CallStaticVoidMethod(methodInfo.classID, methodInfo.methodID, jLongArray, repeat);

methodInfo.env->DeleteLocalRef(methodInfo.classID);

}

void cancelVibrateJNI()

{

JniMethodInfomethodInfo;

if (! getStaticMethodInfo(methodInfo, "cancelVibrate", "()V"))

{

return;

}

methodInfo.env->CallStaticVoidMethod(methodInfo.classID, methodInfo.methodID);

methodInfo.env->DeleteLocalRef(methodInfo.classID);

}

3.2 修改CocosDenshion/include/SimpleAudioEngine.h 增加如下方法.

void vibrate(long long time);

void vibrateWithPattern(long long pattern[], int repeat);

void cancelVibrate();

3.3 修改CocosDenshion/android/SimpleAudioEngine.cpp 增加调用JNI的如下方法。

void SimpleAudioEngine::vibrate(long long time)

{

vibrateJNI(time);

}

void SimpleAudioEngine::vibrateWithPattern(long long pattern[], int repeat)

{

vibrateWithPatternJNI(pattern, repeat);

}

void SimpleAudioEngine::cancelVibrate()

{

cancelVibrateJNI();

}

4. 至此，代码上的修改都OK 啦，在游戏中需要使用震动的地方调用。

CocosDenshion::SimpleAudioEngine::sharedEngine()->vibrate(time);

CocosDenshion::SimpleAudioEngine::sharedEngine()->vibrateWithPattern(pattern,repeat);

取消震动用这个

CocosDenshion :: SimpleAudioEngine :: sharedEngine () -> cancelVibrate ();

最后在 中加上这个



到这里就圆满完成了，网上的教程没有最后一步，所以说最后一步尤其关键。
