        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_camera2_video_image);

        mTextureView = (TextureView) findViewById(R.id.textureView);
        mRecordImageButton = (ImageButton) findViewById(R.id.videoOnlineImageButton);
        mRecordImageButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if(mIsRecording) {
                    mIsRecording = false;
                    mRecordImageButton.setImageResource(R.mipmap.btn_video_online);
                } else {
                    mIsRecording = true;
                    mRecordImageButton.setImageResource(R.mipmap.btn_video_busy);
                }
            }
        });
    }
