使用相机表面查看和他人叠加图像 [英] Using Surface View for camera and others for overlay image

问题描述

即时通讯在Android的编程新..
我在这里有一个问题。

im new in android programming.. i have a problem here.

我想使该画从摄像头等实景重叠的应用程序。
我用的表面视图保持图像从相机。

i wanna make an application that draw overlay on top real view from camera. i use surface view for hold image from camera.

在这里我的XML我的主要活动：

here my XML for my main activity:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
        <SurfaceView
            android:id="@+id/preview"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
        />
        <com.openit.razer.overlayPreview
            android:id="@+id/overlayprev"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent" />
        <com.openit.razer.overlayImage
            android:id="@+id/overlayimg"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent" />
</RelativeLayout>

这是我的主要活动类：
P

and this is my main activity class: p

ublic void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.ar);

        overPrev = (overlayPreview)findViewById(R.id.overlayprev);
        overImg = (overlayImage)findViewById(R.id.overlayimg);

        overImg.setZOrderOnTop(true);
        overImg.getHolder().setFormat(PixelFormat.TRANSPARENT);


        preview=(SurfaceView)findViewById(R.id.preview);
        previewHolder=preview.getHolder();
        previewHolder.addCallback(surfaceCallback);
        previewHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
}
SurfaceHolder.Callback surfaceCallback=new SurfaceHolder.Callback() {
        public void surfaceCreated(SurfaceHolder holder) {
          try {
            camera.setPreviewDisplay(previewHolder);
          }
          catch (Throwable t) {
            Log.e("PreviewDemo-surfaceCallback",
                  "Exception in setPreviewDisplay()", t);
            Toast
              .makeText(ARrazerNav.this, t.getMessage(), Toast.LENGTH_LONG)
              .show();
          }
        }

        public void surfaceChanged(SurfaceHolder holder,
                                   int format, int width,
                                   int height) {

          Camera.Parameters parameters=camera.getParameters();
          //Camera.Size size=getBestPreviewSize(width, height,
                                             // parameters);
          List<Camera.Size> sizes = parameters.getSupportedPreviewSizes();
          Camera.Size selected = sizes.get(0);
          parameters.setPreviewSize(selected.width, selected.height);
          camera.setParameters(parameters);
          if(getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT){
              camera.setDisplayOrientation(90);
          }
          else{
              camera.setDisplayOrientation(0);
          }
          //camera.setDisplayOrientation(90);
          //camera.setDisplayOrientation(0);
          camera.startPreview();
        }

        public void surfaceDestroyed(SurfaceHolder holder) {
          // no-op
        }
      };

但我得到了errror

but i got errror

和什么与SurfaceView和在它上面覆盖图像实现摄像机的最佳方法是什么？

and whats the best method for implementing Camera with SurfaceView and overlay image on top of it?

在此先感谢

推荐答案

您应该使用的FrameLayout上放置的其它视图顶视图。 SurfaceView第一，那么你要在它上面的意见。

You should be using a FrameLayout to place views on top of other views. SurfaceView first, then the views you want on top of it.

我其实这个做我自己，把图像通过摄像头preVIEW。我用的FrameLayout具有SurfaceView，并在它上面的ImageView的。工作pretty很好。

I actually did this myself, putting an image over a camera preview. I used a FrameLayout with a SurfaceView and an ImageView on top of it. Worked pretty well.
