C++ (Cpp) MotionEvent::copyFrom Examples

Example #1

File: InputEvent_test.cpp Project: MIPS/frameworks-native

TEST_F(MotionEventTest, CopyFrom_KeepHistory) {
    MotionEvent event;
    initializeEventWithHistory(&event);

    MotionEvent copy;
    copy.copyFrom(&event, true /*keepHistory*/);

    ASSERT_NO_FATAL_FAILURE(assertEqualsEventWithHistory(&event));
}

Example #2

File: android_view_MotionEvent.cpp Project: LuckJC/pro-fw

static jint android_view_MotionEvent_nativeCopy(JNIEnv* env, jclass clazz,
        jint destNativePtr, jint sourceNativePtr, jboolean keepHistory) {
    MotionEvent* destEvent = reinterpret_cast<MotionEvent*>(destNativePtr);
    if (!destEvent) {
        destEvent = new MotionEvent();
    }
    MotionEvent* sourceEvent = reinterpret_cast<MotionEvent*>(sourceNativePtr);
    destEvent->copyFrom(sourceEvent, keepHistory);
    return reinterpret_cast<jint>(destEvent);
}

Example #3

File: android_view_InputQueue.cpp Project: 0359xiaodong/platform_frameworks_base

static jlong nativeSendMotionEvent(JNIEnv* env, jobject clazz, jlong ptr, jobject eventObj) {
    sp<InputQueue> queue = reinterpret_cast<InputQueue*>(ptr);
    MotionEvent* originalEvent = android_view_MotionEvent_getNativePtr(env, eventObj);
    if (!originalEvent) {
        jniThrowRuntimeException(env, "Could not obtain MotionEvent pointer.");
        return -1;
    }
    MotionEvent* event = queue->createMotionEvent();
    event->copyFrom(originalEvent, true /* keepHistory */);
    queue->enqueueEvent(event);
    return reinterpret_cast<jlong>(event);
}

Example #4

File: InputEvent_test.cpp Project: MIPS/frameworks-native

TEST_F(MotionEventTest, CopyFrom_DoNotKeepHistory) {
    MotionEvent event;
    initializeEventWithHistory(&event);

    MotionEvent copy;
    copy.copyFrom(&event, false /*keepHistory*/);

    ASSERT_EQ(event.getPointerCount(), copy.getPointerCount());
    ASSERT_EQ(0U, copy.getHistorySize());

    ASSERT_EQ(event.getPointerId(0), copy.getPointerId(0));
    ASSERT_EQ(event.getPointerId(1), copy.getPointerId(1));

    ASSERT_EQ(event.getEventTime(), copy.getEventTime());

    ASSERT_EQ(event.getX(0), copy.getX(0));
}

Example #5

File: android_view_MotionEvent.cpp Project: LuckJC/pro-fw

    jobject eventObj = env->CallStaticObjectMethod(gMotionEventClassInfo.clazz,

    }

    MotionEvent* destEvent = android_view_MotionEvent_getNativePtr(env, eventObj);
