Wie Bild von der Kamera von Fragment in Android bekommen

Question

In meinem Code habe ich Null auf Bitmap aber Image erfolgreich erstellt und uri ist in Ordnung, aber BitmapFactory.decodeFile() gibt null zurück.

I verwendet Fragment unter Code:

public class CameraImage extends Fragment { 

private static final int TAKE_PHOTO_CODE = 1888; 
Button button; 
private Uri fileUri1,fileUri; 
ImageView imageView; 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
     Bundle savedInstanceState) { 

    final View rootView = inflater.inflate(R.layout.camera_image, 
      container, false); 

    button = (Button) rootView.findViewById(R.id.button); 
    imageView = (ImageView) rootView.findViewById(R.id.imageview); 

    button.setOnClickListener(new OnClickListener() { 
     @Override 
     public void onClick(View view) { 

      Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
    fileUri1 = getOutputMediaFileUri(); 
    cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); 
    startActivityForResult(cameraIntent, TAKE_PHOTO_CODE); 

     } 
    }); 

    return rootView; 

} 

@Override 
public void onActivityResult(int requestCode, int resultCode, Intent data) { 
    if (requestCode == TAKE_PHOTO_CODE) { 
     if (resultCode == Activity.RESULT_OK) { 

      BitmapFactory.Options options; 


       try { 
        Bitmap bitmap = BitmapFactory.decodeFile(pathname); 
        showDialog(bitmap, 1); 
       } catch (OutOfMemoryError e) { 
        try { 
         options = new BitmapFactory.Options(); 
         options.inSampleSize = 2; 
         Bitmap bitmap = BitmapFactory.decodeFile(pathname, options); 
         imageView.setImageBitmap(bitmap); 
        } catch (Exception e2) { 
         Log.e("Camera", "" + e2 + " " + e); 
        } 
       } 
     } 
    }   
} } 

public Uri getOutputMediaFileUri() { 
    return Uri.fromFile(getOutputMediaFile()); 
} 

private static File getOutputMediaFile() { 

    File mediaStorageDir = new File(
      Environment 
        .getExternalStoragePublicDirectory(MyApplication.getAppContext().getFilesDir().getAbsolutePath()), 
      IMAGE_DIRECTORY_NAME); 

    if (!mediaStorageDir.exists()) { 
     if (!mediaStorageDir.mkdirs()) { 
      Log.d(IMAGE_DIRECTORY_NAME, "Oops! Failed create " 
        + IMAGE_DIRECTORY_NAME + " directory"); 
      return null; 
     } 
    } 
    // Create a media file name 
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss", 
      Locale.getDefault()).format(new Date()); 
    File mediaFile; 

    try { 
     mediaFile = File.createTempFile(
       "IMG_" + timeStamp, 
       ".jpg",   
       mediaStorageDir  
     ); 
    } catch (Exception e) { 
     Log.e("Camera", "" + e); 
     mediaFile = new File(mediaStorageDir.getPath() + File.separator 
       , "IMG_" + timeStamp + ".jpg"); 
    } 
    return mediaFile; 
} 

In obigem Code I auf Bitmap in onActivityResult null bekam aber ich habe uri von diesem Bild an dieser Stelle vorhanden ist.

Answer 1

gibt es zwei Arten von Bild ändern können wir über Kamera erhalten:

1) thumbnail image durch die Verwendung unterer Code in onActivityResult:

Bitmap photo = (Bitmap) data.getExtras().get("data"); 
       Log.i(TAG, "" + photo + "/" + data.getExtras().get("data") + "/" + data.getData()); 
       showDialog(photo, 1); 

2) in voller Qualität immage von unten Code in onActivityResult mit:

BitmapFactory.Options options; 
       options = new BitmapFactory.Options(); 
       options.inSampleSize = 2; 
       Bitmap bitmap = BitmapFactory.decodeFile(pathname, options); 
       showDialog(bitmap, 1); 

3) verwenden Dritte einfach und bequem:

Answer 2

löste ich meine Frage:

von cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);

zu

cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri1);
