How to install Live Frame on a camera to capture images on Android

Question

I need to set live frames on the camera as shown above. But my setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); getWidth(); getHeight(); Camera.PictureCallback etc. Outdated. Does anyone know the code to achieve the above?

I used

 public class CameraOverview1 extends Activity implements SurfaceHolder.Callback{ private Camera camera = null; private SurfaceView cameraSurfaceView = null; private SurfaceHolder cameraSurfaceHolder = null; private boolean previewing = false; private Display display = null; private static int wid = 0, hgt = 0; private LayoutInflater layoutInflater = null; private View cameraViewControl = null; private LayoutParams layoutParamsControl = null; private Button btnCapture = null; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); display = getWindowManager().getDefaultDisplay(); wid = display.getWidth(); hgt = display.getHeight(); getWindow().setFormat(PixelFormat.TRANSLUCENT); requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN); setContentView(R.layout.cameraoverlay1); cameraSurfaceView = (SurfaceView)findViewById(R.id.cameraSurfaceView); cameraSurfaceHolder = cameraSurfaceView.getHolder(); cameraSurfaceHolder.addCallback(this); cameraSurfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); layoutInflater = LayoutInflater.from(getBaseContext()); layoutParamsControl = new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT); cameraViewControl = layoutInflater.inflate(R.layout.cambutton, null); this.addContentView(cameraViewControl, layoutParamsControl); btnCapture = (Button)findViewById(R.id.btnCapture); btnCapture.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub camera.takePicture(cameraShutterCallback, cameraPictureCallbackRaw, cameraPictureCallbackJpeg); } }); } ShutterCallback cameraShutterCallback = new ShutterCallback() { @Override public void onShutter() { // TODO Auto-generated method stub } }; PictureCallback cameraPictureCallbackRaw = new PictureCallback() { @Override public void onPictureTaken(byte[] data, Camera camera) { // TODO Auto-generated method stub } }; PictureCallback cameraPictureCallbackJpeg = new PictureCallback() { @Override public void onPictureTaken(byte[] data, Camera camera) { // TODO Auto-generated method stub Bitmap cameraBitmap = BitmapFactory.decodeByteArray(data, 0, data.length); wid = cameraBitmap.getWidth(); hgt = cameraBitmap.getHeight(); Bitmap newImage = Bitmap.createBitmap(wid, hgt, Bitmap.Config.ARGB_8888); Canvas canvas = new Canvas(newImage); canvas.drawBitmap(cameraBitmap, 0f, 0f, null); Drawable drawable = getResources().getDrawable (R.drawable.frame1); drawable.setBounds(0, 0, wid, hgt); drawable.draw(canvas); File storagePath = new File(Environment. getExternalStorageDirectory() + "/MyCameraApp/"); storagePath.mkdirs(); File myImage = new File(storagePath, Long.toString(System.currentTimeMillis()) + ".jpg"); try { FileOutputStream out = new FileOutputStream(myImage); newImage.compress(Bitmap.CompressFormat.JPEG, 80, out); out.flush(); out.close(); } catch(FileNotFoundException e) { Log.d("In Saving File", e + ""); } catch(IOException e) { Log.d("In Saving File", e + ""); } camera.startPreview(); drawable = null; newImage.recycle(); newImage = null; cameraBitmap.recycle(); cameraBitmap = null; } }; @Override public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) { // TODO Auto-generated method stub if(previewing) { camera.stopPreview(); previewing = false; } if (camera != null){ try { camera.setPreviewDisplay(cameraSurfaceHolder); camera.startPreview(); previewing = true; } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } @Override public void surfaceCreated(SurfaceHolder holder) { // TODO Auto-generated method stub try { camera = Camera.open(); } catch(RuntimeException e) { Toast.makeText(getApplicationContext(), "Device camera is not working properly, please try after sometime.", Toast.LENGTH_LONG).show(); } } @Override public void surfaceDestroyed(SurfaceHolder holder) { // TODO Auto-generated method stub camera.stopPreview(); camera.release(); camera = null; previewing = false; }} 

Actually, almost everything is out of date. Any ideas?

Based on this example android-Camera2Basic

I applied some changes, and this is the result:

Camera2BasicFragmentFront.java

A source

Camera2BasicFragment.java

A source

AutoFitTextureView.java

A source

fragment_camera2_basic.xml (be sure to replace com.YourPackage.AutoFitTextureView)

activity_main.xml

 <RelativeLayout android:layout_width="match_parent" android:layout_height="match_parent" xmlns:android="http://schemas.android.com/apk/res/android"> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/container" android:layout_width="match_parent" android:layout_height="match_parent" > </FrameLayout> <FrameLayout android:id="@+id/containerFront" android:layout_width="200dp" android:layout_height="200dp" /> </RelativeLayout> 

Than in MainActivity.java:

 public class MainActivity extends AppCompatActivity{ @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); if (null == savedInstanceState) { getFragmentManager().beginTransaction() .replace(R.id.container, Camera2BasicFragment.newInstance()) .commit(); getFragmentManager().beginTransaction() .replace(R.id.containerFront, Camera2BasicFragmentFront.newInstance()) .commit(); } } } 

And use this permission for Manifest.xml

 <uses-permission android:name="android.permission.CAMERA" /> <uses-feature android:name="android.hardware.camera" /> <uses-feature android:name="android.hardware.camera.autofocus" /> 

I like it all!

PS Java classes also contain a method for saving photos!
