private Mat                    mFinalMat;


public CameraBridgeViewBase   mOpenCvCameraView;



private BaseLoaderCallback     mLoaderCallback = new BaseLoaderCallback(this) {

推荐答案

我可以按照以下步骤操作.

I got it working by following these steps.

1. 删除ActionBar-转到值/样式并更改

1. Remove ActionBar - Go to values/styles and change

style name ="AppTheme" parent ="Theme.AppCompat.Light.DarkActionBar"

style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar"

到

样式名称="AppTheme" parent ="Theme.AppCompat.NoActionBar"

style name="AppTheme" parent="Theme.AppCompat.NoActionBar"

设置最大帧大小-使用此代码设置帧大小.

Set max frame size - use this code to set the frame size.

mOpenCvCameraView.setMaxFrameSize(720，480);

mOpenCvCameraView.setMaxFrameSize(720, 480);
