我在我的布局文件中使用来自新的Design Support库22.2.0的android.support.design.widget.FloatingActionButton.它工作正常但它在API级别17下方显示了一个方形按钮

我正在创建一个自定义相机应用程序,我发现了Nexus 7的一个严重问题.当我用前置摄像头录制视频时,录制的视频是流畅的并且再现相同的颜色,但如果使用后置摄像头完成录制,再现的颜色是红色变为蓝色和黄色变为青色.此问题仅在Nexus 7中发生.有人可以帮助解决方案.

    mMediaRecorder = new MediaRecorder();

    // Step 1: Unlock and set camera to MediaRecorder
    mCamera.unlock();
    mMediaRecorder.setCamera(mCamera);
    mMediaRecorder.setMaxDuration(25000);
    if (mCameraPosition == CameraInfo.CAMERA_FACING_FRONT) {

        if (orientation == Configuration.ORIENTATION_LANDSCAPE)
            mMediaRecorder.setOrientationHint(0);
        else if (orientation == Configuration.ORIENTATION_PORTRAIT)
            mMediaRecorder.setOrientationHint(270);
        else if (orientation == REVERSED_LANDSCAPE) {
            mMediaRecorder.setOrientationHint(180);
        } else {
            mMediaRecorder.setOrientationHint(90);
        }

    } else {

        if (orientation == Configuration.ORIENTATION_PORTRAIT) {
            mMediaRecorder.setOrientationHint(angle);
        } else if (orientation == Configuration.ORIENTATION_LANDSCAPE) {
            mMediaRecorder.setOrientationHint(0);
        } else if (orientation == REVERSED_LANDSCAPE) {
            mMediaRecorder.setOrientationHint(180);
        } else {
            mMediaRecorder.setOrientationHint(270);
        }

    }
