The game will have its own thread (game engine) to draw and update drawables. I have 3 classes to achieve this, namely BattleActivity, BattleView, and BattleThread. The BattleActivity is called from another activity. BattleThread will call BattleView.update() and BattleView.render() to do the job. But I don't see anything working. I know it all is reachable through logging and debugging (which I have tried), but I still

What I'm trying to do is using the onPreviewFrame method, which is invoked each time a new frame is drawn into the SurfaceView , in order to execute the invalidate method which is supposed to invoke the onDraw method. In fact, the onDraw method is being invoked, but nothing there is being printed (I guess the camera preview is overwriting the text I'm trying to draw). This is a simplify version of the SurfaceView subclass I have: public class

I found this link but it does not work. Any idea ? 回答1: In your activity's onCreate: // Add admob ads. admobView = new AdView(this, AdSize.BANNER, "YOUR_UNIT_ID"); RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams( RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT); lp.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM); admobView.setLayoutParams(lp); RelativeLayout layout = new RelativeLayout

I'm new at java and OpenGL. I'm trying to get a camera preview screen with the ability to display 3d objects simultaneously. Having gone through the samples at the api demos, I thought combining the code for the the examples at the api demo would suffice. But somehow its not working. The forces me to shut down upon startup and the error is mentioned as null pointer exception. Could someone share with me where did I go wrong and how to proceed from there. How I did the combination for the code is as shown below: myoverview.xml <?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android=

I looked at an earlier question about how to attach the MediaPlayer to the SurfaceView. The answer to the question tells me to create two functions: @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_player); getWindow().setFormat(PixelFormat.UNKNOWN); mPreview = (SurfaceView)findViewById(R.id

应用程序的视频或者opengl内容往往是显示在一个特别的UI控件中：SurfaceView。SurfaceView的工作方式是创建一个置于应用窗口之后的新窗口。这种方式的效率非常高，因为SurfaceView窗口刷新的时候不需要重绘应用程序的窗口（android普通窗口的视图绘制机制是一层一层的，任何一个子元素或者是局部的刷新都会导致整个视图结构全部重绘一次，因此效率非常低下，不过满足普通应用界面的需求还是绰绰有余），但是SurfaceView也有一些非常不便的限制。 因为SurfaceView的内容不在应用窗口上，所以不能使用变换（平移、缩放、旋转等）。也难以放在ListView或者ScrollView中，不能使用UI控件的一些特性比如View.setAlpha()。 为了解决这个问题 Android 4.0中引入了TextureView。它们都可以在另一个独立线程中绘制和渲染，这是和其它View的最大不同。 与SurfaceView相比，TextureView并没有创建一个单独的Surface（表面）用来绘制，这使得它可以像一般的View一样执行一些变换操作，设置透明度等。另外，Textureview必须在硬件加速开启的窗口中。 TextureView的使用非常简单，我们要做的就是获取用于渲染内容的SurfaceTexture（它能捕获一个图像流的一帧来作为OpenGL

Im creating a game in android, and i noticed that the game has a memory leak. Iv managed to isolate the memory leak into a smaller application so that i can see well try and work out, how to fix it. The application uses a surfaceview for its view and has a thread attached to that in order to do all the drawing to the screen. The memory leak happens when i start a new activity and close the one that im currently using. I can see this when i do a memory dump on my test application as all it does is open and close an activity (activity a -> activity b -> activity a). Iv kind of ran out of ideas

I am trying to open the camera hardware on a SurfaceView. In the layout, I created a SurfaceView and I open the camera as shown in the code below. When I run the code, the toast in the CameraAvailableCB shows up and says "onCameraAvailable" but nothing appears on the SurfaceView. How do I show the camera display on the SurfaceView? Code @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); this.mBtnCapture = (Button) findViewById(R.id.actMain_btn_capture); this.mSurfaceView = (SurfaceView) findViewById(R.id

I would like to know how to draw a rectangle in specific position and size. I tried a couple of trials and examples here and on web, but nothing worked for me. I'm using a SurfaceView and SurfaceHolder to hold the camera preview. I just want to draw a rectangle when the user touch on the screen. I don't want to use external library and When I'm trying to get the canvas from the holder I'm getting null. For now there is no code, cause nothing work for me, if someone has a clue how to do it, I will try it. This is what I've already tried: Link 1 Link 2 Link 3 Thanks for help! user2235615 Ok,
