SurfaceView hides other components on screen

问题 I am creating a layout of type FrameLayout, in which I am adding two views. Two views are objects of GLSurfaceView and SurfaceView respectively. According to Android Developers Documentation regarding SurfaceView, "The surface is Z ordered so that it is behind the window holding its SurfaceView; the SurfaceView punches a hole in its window to allow its surface to be displayed." It works well for me and SurfaceView always stays behind my GLSurfaceView (used for opneGL drawings). But resuming

由 一曲冷凌霜 提交于 2020-01-21 06:44:06
问题 I'm trying to implement pinch zoom on a SurfaceView . I've done a lot of research regarding this and I found this class to implement pinch zoom. Here is how I modified it: public class ZoomLayout extends FrameLayout implements ScaleGestureDetector.OnScaleGestureListener { private SurfaceView mSurfaceView; private enum Mode { NONE, DRAG, ZOOM } private static final String TAG = "ZoomLayout"; private static final float MIN_ZOOM = 1.0f; private static final float MAX_ZOOM = 4.0f; private Mode

unity打包android项目在模拟器上被surfaceview遮挡

1.在手机端，surfaceview在unity布局之下，并没有错误，但是在模拟器上产生了这个问题，想了很多办法， 看到了大佬的思路，就是自定义UnityPlayer，重写addview方法，找到父布局下的surfaceview控件，然后进行操作，具体操作看大佬链接： https://www.jianshu.com/p/2ba2bbf247ce 其中，将false改为ture即可。 if (child is SurfaceView) { child.setZOrderOnTop(false) } 来源： CSDN 作者： YaphetS_Zero 链接： https://blog.csdn.net/YaphetS_Zero/article/details/103805364

[Android/安卓]屏幕旋转时改变SurfaceView（视频）宽高

由 流过昼夜 提交于 2020-01-17 23:55:07
主要解决自定义SurfaceView时，屏幕发生旋转后，SurfaceView也会跟随旋转的问题（因为是做播放器，所以SurfaceView宽高需要由视频宽高决定），最后SurfaceView还需要等比例缩放成屏幕的宽高。 int mWidth = getMeasuredWidth(); int mHeight = getMeasuredHeight(); int oldAngle = 90; /** * 旋转更新（屏幕旋转时调用，0和180 -> 横屏，90和270 -> 竖屏） * 屏幕旋转需要考虑旋转后的高宽变化，例如：竖屏时，高比宽大，横屏时：高比宽小。 * 所以旋转后要确定那边为宽，那边为高，然后将视频等比例缩放至屏幕相应大小。 * @param angle 旋转角度。传入0、180、90、270 */ private void updateOrientation(int angle) { if( videoWidth <= 0 || videoHeight <= 0 ) return; //需要改变宽高的LayoutParams ViewGroup.LayoutParams lp = getLayoutParams(); //是否为横版视频 boolean isLandscapeVideo = videoWidth > videoHeight; //是否为横屏

screenshot android presentation display/surface

问题 I would like to make "instant" screenshots of an Presentation object in Android. My Presentation normally renders to a virtual display (PRIVATE) which is backed by the surface from a MediaRecorder that is setup to record video. Recording the presentation as a video works great. mMediaRecorder = new MediaRecorder(); mMediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC); mMediaRecorder.setVideoSource(MediaRecorder.VideoSource.SURFACE); mMediaRecorder.setOutputFormat(MediaRecorder
