static void nativeReparent(JNIEnv* env, jclass clazz, jlong transactionObj,
        jlong nativeObject,
        jlong newParentObject) {
    auto ctrl = reinterpret_cast<SurfaceControl *>(nativeObject);
    auto newParent = reinterpret_cast<SurfaceControl *>(newParentObject);
    auto transaction = reinterpret_cast<SurfaceComposerClient::Transaction*>(transactionObj);
    transaction->reparent(ctrl, newParent);
}

• 先通过地址获取当前 SurfaceControl 和父 SurfaceControl 还有 SurfaceComposerClient::Transaction 指针。
• 调用 Transaction.reparent()。
