将MotionEvent从Java发送到JNI

public native void processMotionEvent(MotionEvent event);

JNIEXPORT void JNICALL Java_com_example_MyClass_processMotionEvent(JNIEnv* env, jobject obj, jobject event) {
    // 获取MotionEvent类及其方法ID
    jclass motionEventClass = env->GetObjectClass(event);
    jmethodID getActionMethod = env->GetMethodID(motionEventClass, "getAction", "()I");
    jmethodID getXMethod = env->GetMethodID(motionEventClass, "getX", "()F");
    jmethodID getYMethod = env->GetMethodID(motionEventClass, "getY", "()F");

    // 获取MotionEvent的动作类型和坐标
    jint action = env->CallIntMethod(event, getActionMethod);
    jfloat x = env->CallFloatMethod(event, getXMethod);
    jfloat y = env->CallFloatMethod(event, getYMethod);

    // 进行相应的处理逻辑
    // ...

    // 释放局部引用
    env->DeleteLocalRef(motionEventClass);
}

MotionEvent event = MotionEvent.obtain(...); // 创建MotionEvent对象，填充相关信息
processMotionEvent(event); // 调用JNI方法，将MotionEvent传递给JNI层进行处理
event.recycle(); // 回收MotionEvent对象
