Установите ImageView с выбранным изображением из камеры или галереи

Question

В моей деятельности я хочу поставить в ImageView фотографию с камеры или галереи! Из камеры этот код работает хорошо, а когда я беру изображение из галереи, он работает до тех пор, пока я не выбираю свою фотографию! После этого он не дает мне это в образе просмотра! Кто может мне помочь?

Вот это MainActivity код:

public class MainActivity extends Activity { 
    private Button mTakePhoto; 
    private ImageView mImageView; 

    private static final int CAMERA_REQUEST = 1; 
    private static final int PICK_FROM_GALLERY = 2; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     mTakePhoto = (Button) findViewById(R.id.take_photo); 
     mImageView = (ImageView) findViewById(R.id.imageview); 


     final String[] option = new String[] { "Take from Camera", "Select from Gallery" }; 

     ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.select_dialog_item, option); 
     AlertDialog.Builder builder = new AlertDialog.Builder(this); 

     builder.setTitle("Select Option"); 
     builder.setAdapter(adapter, new DialogInterface.OnClickListener() { 

      public void onClick(DialogInterface dialog, int which) { 
       // TODO Auto-generated method stub 
       Log.e("Selected Item", String.valueOf(which)); 
       if (which == 0) { 
        callCamera(); 
       } 
       if (which == 1) { 
        callGallery(); 
       } 

      } 
     }); 
     final AlertDialog dialog = builder.create(); 

     mTakePhoto.setOnClickListener(new View.OnClickListener() { 
      public void onClick(View v) { 
       dialog.show(); 
      } 
     }); 

    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.main, menu); 
     return true; 
    } 


    @Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     // TODO Auto-generated method stub 

     if (resultCode != RESULT_OK) 
      return; 

     switch (requestCode) { 
     case CAMERA_REQUEST: 

      setPic(); 

      break; 
     case PICK_FROM_GALLERY: 

      Bundle extras2 = data.getExtras(); 

      if (extras2 != null) { 
       Bitmap yourImage = extras2.getParcelable("data"); 
       // convert bitmap to byte 
       ByteArrayOutputStream stream = new ByteArrayOutputStream(); 
       yourImage.compress(Bitmap.CompressFormat.PNG, 100, stream); 
       byte imageInByte[] = stream.toByteArray(); 
       Log.e("output before conversion", imageInByte.toString()); 
       // Inserting Contacts 
       Log.d("Insert: ", "Inserting .."); 

       Intent i = new Intent(MainActivity.this, MainActivity.class); 

       startActivity(i); 

       finish(); 
      } 

      break; 
     } 
    } 

    @Override 
    protected void onResume() { 
     // TODO Auto-generated method stub 
     super.onResume(); 
     Log.i(TAG, "onResume: " + this);

    } 

    private void setPic() { 
     // Get the dimensions of the View 
     int targetW = mImageView.getWidth(); 
     int targetH = mImageView.getHeight(); 

     // Get the dimensions of the bitmap 
     BitmapFactory.Options bmOptions = new BitmapFactory.Options(); 
     bmOptions.inJustDecodeBounds = true; 
     BitmapFactory.decodeFile(mCurrentPhotoPath, bmOptions); 
     int photoW = bmOptions.outWidth; 
     int photoH = bmOptions.outHeight; 

     // Determine how much to scale down the image 
     int scaleFactor = Math.min(photoW/targetW, photoH/targetH); 

     // Decode the image file into a Bitmap sized to fill the View 
     bmOptions.inJustDecodeBounds = false; 
     bmOptions.inSampleSize = scaleFactor << 1; 
     bmOptions.inPurgeable = true; 

     Bitmap bitmap = BitmapFactory.decodeFile(mCurrentPhotoPath, bmOptions); 

     Matrix mtx = new Matrix();

Answer 1

Потому что у вас есть этот код в вашей камере:

mImageView.setImageBitmap(rotatedBMP); 

Но вы не имеете его в галерее , Вы также должны установить растровое изображение в case PICK_FROM_GALLERY на onActivityResult.

Код должен выглядеть так:

if (extras2 != null) 
{ 
    Bitmap yourImage = extras2.getParcelable("data"); 
    //your other code 
    mImageView.setImageBitmap(yourImage); 
}
