Come impostare Telaio Live Camera Image Catturare in Android

Question

devo impostare le cornici in diretta su macchina fotografica come sopra pic. Ma il mio setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);getWidth();getHeight();Camera.PictureCallback ecc. Sono deprecati. Qualcuno conosce il codice per ottenere quanto sopra?

ho usato

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; 
}} 

In realtà, praticamente tutto è deprecato. Qualche idea?

Sulla base di questo campione android-Camera2Basic

ho applicato qualche cambiamento, e questo è il risultato:

Camera2BasicFragmentFront.java

Source

Camera2BasicFragment.java

Source

AutoFitTextureView.java

Source

fragment_camera2_basic.xml (Assicurati di sostituire com.YourPackage.AutoFitTextureView)

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"> 

    <com.YourPackage.AutoFitTextureView 
     android:id="@+id/texture" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_alignParentStart="true" 
     android:layout_alignParentTop="true" /> 

</RelativeLayout> 

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(); 
     } 
    } 
} 

E utilizzare questa autorizzazione per Manifest.xml

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

questo è tutto godere!

P.S Le classi Java contengono anche il metodo per salvare le foto!
