You can see we make the SurfaceView (our camera preview) match the full width and height of the layout, taking up the full screen. We use a RelativeLayout as the parent so we can then create an overlay view, here another RelativeLayout, and align it to the bottom of the parent, on top of the preview 2 Answers2. Result: it's not possible. surfaceView.setZOrderOnTop (true) will cause SF to be on the very top, so you just can't draw anything over it. And with setZOrderOnTop (false), you can put views over SF, but its background won't be transparent (and that's what I need too..). And that's quite sad

When the SurfaceView is attached to the display window, it calls ViewParent.requestTransparentRegion (View) which requests a computation of the transparent regions on the display. At this point, the View isn't visible, causing the overlapped region between the SurfaceView and the View to be considered transparent Control whether the surface view's surface is placed on top of another regular surface view in the window (but still behind the window itself). Control whether the surface view's surface is placed on top of its window. Bring up the context menu for this view. Start an action mode with the default type Primary

OverlayView is a subclass of SurfaceView with the drawing and animation thread implementations. The other SurfaceView will be the surface that handles the Camera preview. Inside of onCreate you should set up your views like this Maybe you as Android Framework Developer can give a recommendation on how I best implement the following: I have camera preview and want to overlay my own item over this that change very quickly (about every 200ms). The camera preview uses a SurfaceView as in the samples. As first approach I used a normal View as the overlay part and calle Provides a dedicated drawing surface embedded inside of a view hierarchy. You can control the format of this surface and, if you like, its size; the SurfaceView takes care of placing the surface at the correct location on the scree

  1. There is an Api Demo showing how to generally do this with a surface view. It's very easy, since SurfaceView essentially operates like any other view in terms of compositing. On Fri, Jan 30, 2009 at 3:48 PM, srajpal < sra...@gmail.com > wrote
  2. To ensure the VideoView of the NewFragment appears on top, simply call `setZOrderMediaOverlay (true)` on the VideoView in the NewFragment. This method Controls whether the surface view's surface is placed on top of another regular surface view in the window (but still behind the window itself). This is typically used to place overlays on.
  3. Android Unity plugins and Ad Networks — The issue with Unity 5.6. When Unity 5.6 was released, most of the ad network plugins stopped working properly. Developers started reporting that they.

Ok, so what you have to do is have a valid SurfaceView for the camera preview to start, but you can't just hide it after passing it to setPreviewDisplay() because the surface will detect that and will sto android.view.SurfaceView. #. setOnTouchListener () The following examples show how to use android.view.SurfaceView #setOnTouchListener () . These examples are extracted from open source projects. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above.

Later if the View becomes visible, it will not be displayed on top of SurfaceView. A way around this is to call ViewParent.requestTransparentRegion (View) right after making the View visible, or initially hiding the View by setting its opacity to 0, then setting it to 1.0F to show it The SurfaceView issue makes this a little more complicated to completely solve without users needing any Android specific workarounds. FlutterView extends SurfaceView, and SurfaceView needs to either render completely below or completely on top of the rest of the app. The default is to render it completely below, so transparency ends up being. Implementing Grafika's Double Decode with SurfaceView is harder than implementing with TextureView because SurfaceView objects destroy surfaces during orientation changes. Additionally, using SurfaceView objects adds two layers, which isn't ideal because of the limitations on the number of overlays available on the hardware TextureView behaves as a regular android.view.View, and you can animate, transform, scale or even overlay one with another. But this advantage consumes more memory than SurfaceView, and you lose performance (avg. 1-3 frames). Coming back to the point, as we wanted that our custom view acts as a regular Android View, we should use TextureView The view hierarchy will take care of correctly * compositing with the Surface any siblings of the SurfaceView that would * normally appear on top of it. This can be used to place overlays such as * buttons on top of the Surface, though note however that it can have an * impact on performance since a full alpha-blended composite will be.

SurfaceView with drawing thread#. This example describes how to create a SurfaceView with a dedicated drawing thread. This implementation also handles edge cases such as manufacture specific issues as well as starting/stopping the thread to save cpu time. This layout only contains the custom SurfaceView and maximizes it to the screen size These overlay planes are the only way to display DRM content (DRM-protected buffers can't be accessed by SurfaceFlinger or the OpenGL ES driver). DRM-protected video can be presented only on an overlay plane. Video players that support protected content must be implemented with SurfaceView All groups and messages. Now for the game itself. First, we start by implementing a game thread: public class Game extends SurfaceView implements SurfaceHolder.Callback, Runnable{ /** * Holds the surface frame */ private SurfaceHolder holder; /** * Draw thread */ private Thread drawThread; /** * True when the surface is ready to draw */ private boolean surfaceReady = false; /** * Drawing thread flag */ private boolean.

In this case, building against API 23, so permissions are handled too. You must add in the Manifest the following permission (wherever the API level you're using): <uses-permission android:name=android.permission.CAMERA/>. We're about to create an activity (Camera2Activity.java) that fills a TextureView with the preview of the device's camera Performance. RealtimeBlurView use RenderScript to blur the bitmap, just like 500px-android-blur. Everytime your window draw, it will render a blurred bitmap, so there is a performance cost. Set downsampleFactor>=4 will significantly reduce the render cost. However, if you just want to blur a static view, 500px-android-blur is good enough

This is because that icon is NOT inside the Overlay. It is inside a SurfaceView, which is a sibling of Overlay. Scandit writes the camera stream to this View. It also writes the Flashlight Icon (if the phone has flashlight) and camera-switch icon (if phone has 2 cameras). As a developer, I do not think we can modify the the SurfaceView ourselves Android SurfaceView drawing overlay refresh and dirty rectangle refresh method SurfaceView is the most suitable for game development in Android.

First we create 2 layout files (1) the layout which holds the SurfaceView and (2) the layout which hold the image we want to display SurfaceView and GLSurfaceView. The Android app framework UI is based on a hierarchy of objects that start with a View. All UI elements go through a series of measurements and a layout process that fits them into a rectangular area. Then, all visible view objects are rendered to a surface that was set up by the WindowManager when the app was.

WindowManager then sends the surface to the app, but keeps the SurfaceControl to manipulate the appearance of the app on the screen. Android 10 adds ASurfaceControl, which is another way that SurfaceFlinger can accept buffers. ASurfaceControl combines a surface and a SurfaceControl.

A camera application can use more than one stream of frames simultaneously. In some cases, different streams even require a different frame resolution or pixel format. Some typical use cases include: Video recording: one stream for preview, another being encoded and saved into a file. Barcode scanning: one stream for preview, another for.

The following code examples are extracted from open source projects. You can click to vote up the examples that are useful to you Providing an overlay. Now that the camera preview is being rendered into a SurfaceView, the next step in augmented reality is the ability to draw pixels and/or shapes over the preview image.Since the camera hardware is directly drawing to the surface made available to it, this surface cannot be used for additional drawing: any output made to the surface will be automatically overwritten by the. I have a SurfaceView object that I would like to reorganize constantly (bring to front, bring back, have another view go on top of it, etc.), but once I bring the SurfaceView to the front with setZOrderMediaOverlay (true), I can no longer reverse/change this (even by removing the SurfaceView, setting the z order again, and adding back the.
