surfaceview

I'm creating a camera app that implements it's own camera preview for taking pictures. The app is currently forced into portrait mode. My problem is that the preview from the camera is slightly stretched (the aspect ratio is a bit off). The funny thing is that I'm setting my SurfaceView size to always match the preview size. This ensures that the aspect ratio should always be perserved... but it isn't... Here is the layout i use to show my camera preview: public class Cp extends ViewGroup implements SurfaceHolder.Callback { private final String TAG = "CameraPreview"; private boolean

Like many others, I am trying to draw 3D objects (using GLSurfaceView) on camera preview (using SurfaceView), along with some buttons placed on top. I actually got a prototype working, but I could not get the onResume working correctly. After a resume, GLSurfaceView stays behind and is not visible anymore. I know that it is working, because I can see the drawing fine if I remove the SurfaceView from the layout. The target is Nexus One, running stock 2.3.3 ROM. Here's the layout xml: <com.example.cameratest.GLPreview android:id="@+id/cubes" android:layout_width="fill_parent" android:layout

I have simple layout <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/RelativeLayout1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@drawable/backgroundtimer" android:orientation="vertical" > <TextView android:id="@+id/TextView1" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:text="@string/hello" /> <com.fmech.zenclock.surface.ZenClockSurface android:id="@+id

Android Camera 一文简单介绍了如何在自己的App里实时显示Camera，但有时我们的App不只是要显示图像，可能还要添加其他信息，如在指定位置画Rectangle等等。 stackoverflow 中有人问到如何在camera的SurfaceView中画矩形，最后，提问者根据别人的 建议给出了如下答案: 新建一个与Camera重叠的SurfaceView，然后将该SurfaceView设置透明背景，然后就可以绘制你想绘制的代码图形了。 我测试了下，发现，新建View也是可以的。 layout如下: <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="match_parent" android:layout_height="match_parent"> <FrameLayout android:id="@+id/camera_preview" android:layout_width="320dp" android:layout_height="240dp" /> <view.TestView android:id="@+id/TransparentView"

I was informed in a later answer that I have to add the GestureOverlayView I create in code to my view hierarchy, and I am not 100% how to do that. Below is the original question for completeness. I want my game to be able to recognize gestures. I have this nice SurfaceView class that I do an onDraw to draw my sprites, and I have a thread thats running it to call the onDraw etc . This all works great. I am trying to add the GestureOverlayView to this and it just isn't working. Finally hacked to where it doesn't crash but this is what i have public class Panel extends SurfaceView implements

Every time I pause my activity (actually Fragment) to go to another app, upon returning with onResume I try to resume the video playing but it does not play: I get a blank screen. Upon investigation, I see the following in the Logcat E/BufferQueueProducer: [unnamed-23827-0] queueBuffer: BufferQueue has been abandoned E/MediaPlayer: error (1, -38) E/MediaPlayer: error (1, -38) E/MediaPlayer: error (1, -38) E/MediaPlayer: error (1, -38) E/BufferQueueProducer: [unnamed-23827-0] connect(P): BufferQueue has been abandoned Here is the code I call inside on resume player.seekTo(mVideoSeekPosition);
