Thanks for the feedback Rob,
Stuff like this is never easy but wow… what a feature set would be opened up to corona developers!
Here’s a bit more java/xml that does it… basically take the
<?xml version=“1.0” encoding=“utf-8”?>
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width=“fill_parent”
android:layout_height=“fill_parent” >
<android.view.SurfaceView
android:id="@+id/surface"
android:layout_width=“fill_parent”
android:layout_height=“fill_parent” />
<ImageView
android:id = “@+id/header”
android:layout_width = “wrap_content”
android:layout_height = “wrap_content” />
</FrameLayout>
and for the java code you should extend SurfaceHolder.Callback in your activity and then attach the camera to the surface view like this,its my full code please be careful with bitmaps and canvas that is the tricky part :
public class MainActivity extends Activity implements SurfaceHolder.Callback
{
private Camera camera = null;
private SurfaceView cameraSurfaceView = null;
private SurfaceHolder cameraSurfaceHolder = null;
private boolean previewing = false;
RelativeLayout relativeLayout;
private Button btnCapture = null;
private Button btnsave = null;
private Button btnshare = null;
private boolean isSaved=false;
private boolean isCaptured=false;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
getWindow().setFormat(PixelFormat.TRANSLUCENT);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(
WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_main);
relativeLayout=(RelativeLayout) findViewById(R.id.containerImg);
relativeLayout.setDrawingCacheEnabled(true);
cameraSurfaceView = (SurfaceView)
findViewById(R.id.surfaceView1);
// cameraSurfaceView.setLayoutParams(new FrameLayout.LayoutParams(640, 480));
cameraSurfaceHolder = cameraSurfaceView.getHolder();
cameraSurfaceHolder.addCallback(this);
// cameraSurfaceHolder.setType(SurfaceHolder.
// SURFACE_TYPE_PUSH_BUFFERS);
btnCapture = (Button)findViewById(R.id.capturebtn);
btnCapture.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v)
{
camera.takePicture(cameraShutterCallback,
cameraPictureCallbackRaw,
cameraPictureCallbackJpeg);
isCaptured=true;
}
});
btnsave = (Button)findViewById(R.id.savebtn);
btnsave.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
FrameLayout frm = (FrameLayout)findViewById(R.id.frameLayout1);
frm.setDrawingCacheEnabled(true);
frm.buildDrawingCache();
Bitmap bitmap = frm.getDrawingCache();
try {
File rootFile=new File(Environment.getExternalStorageDirectory().toString()+"/MYCAMERAOVERLAY");
rootFile.mkdirs();
Random generator = new Random();
int n = 10000;
n = generator.nextInt(n);
String fname = “Image-”+ n +".png";
File resultingfile = new File(rootFile, fname);
if (resultingfile.exists ()) resultingfile.delete ();
try {
FileOutputStream Fout = new FileOutputStream(resultingfile);
bitmap.compress(CompressFormat.PNG, 100, Fout);
Fout.flush();
Fout.close();
} catch (FileNotFoundException e) {
Log.d(“In Saving File”, e + “”);
}
} catch(IOException e){
Log.d(“In Saving File”, e + “”);
}
isSaved=true;
}
});
btnshare = (Button)findViewById(R.id.sharebtn);
btnshare.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
if((isSaved)&&(isCaptured)){
// TODO sharing what ever we saved
// take the path
}
}
});
}
