Wie beschneiden Bilder von der Kamera

Question

Wie kann ich die Kamerabilder zuschneiden. Jetzt zeigt es das Bild für den Schnitt und nach dem Auswählen des Schnittabschnitts, während Sie auf die Schaltfläche "Speichern" tippen. Es zeigt als "Bild speichern". Danach passiert nichts. Hier ist mein Code.

Button-Klick:

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
intent.putExtra(MediaStore.EXTRA_OUTPUT, MediaStore.Images.Media.EXTERNAL_CONTENT_URI.toString()); 
intent.putExtra("crop", "true"); 
intent.putExtra("aspectX", 0); 
intent.putExtra("aspectY", 0); 
intent.putExtra("outputX", 200); 
intent.putExtra("outputY", 150); 
intent.putExtra("return-data", true); 
startActivityForResult(intent, CAMERA_PIC_REQUEST); 

onActivityResult:

Bundle extras = data.getExtras(); 
Bitmap bitmap = (Bitmap) extras.get("data"); 
if (bitmap != null) { 
    Img_View.setImageBitmap(bitmap); 
}

Sie diesen Code Zuschneiden ausführen können:

..... 
final int CAMERA_CAPTURE = 1; 
final int CROP_PIC = 2; 
private Uri picUri; 
.... 
@Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     Button captureBtn = (Button) findViewById(R.id.capture_btn); 
     captureBtn.setOnClickListener(this); 
    } 

    public void onClick(View v) { 
     if (v.getId() == R.id.capture_btn) { 
      try { 
       // use standard intent to capture an image 
       Intent captureIntent = new Intent(
         MediaStore.ACTION_IMAGE_CAPTURE); 
       // we will handle the returned data in onActivityResult 
       startActivityForResult(captureIntent, CAMERA_CAPTURE); 
      } catch (ActivityNotFoundException anfe) { 
       Toast toast = Toast.makeText(this, "This device doesn't support the crop action!", 
         Toast.LENGTH_SHORT); 
       toast.show(); 
      } 
     } 
    } 

    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     if (resultCode == RESULT_OK) { 
      if (requestCode == CAMERA_CAPTURE) { 
       // get the Uri for the captured image 
       picUri = data.getData(); 
       performCrop(); 
      } 
      // user is returning from cropping the image 
      else if (requestCode == CROP_PIC) { 
       // get the returned data 
       Bundle extras = data.getExtras(); 
       // get the cropped bitmap 
       Bitmap thePic = extras.getParcelable("data"); 
       ImageView picView = (ImageView) findViewById(R.id.picture); 
       picView.setImageBitmap(thePic); 
      } 
     } 
    } 

    /** 
    * this function does the crop operation. 
    */ 
    private void performCrop() { 
     // take care of exceptions 
     try { 
      // call the standard crop action intent (the user device may not 
      // support it) 
      Intent cropIntent = new Intent("com.android.camera.action.CROP"); 
      // indicate image type and Uri 
      cropIntent.setDataAndType(picUri, "image/*"); 
      // set crop properties 
      cropIntent.putExtra("crop", "true"); 
      // indicate aspect of desired crop 
      cropIntent.putExtra("aspectX", 2); 
      cropIntent.putExtra("aspectY", 1); 
      // indicate output X and Y 
      cropIntent.putExtra("outputX", 256); 
      cropIntent.putExtra("outputY", 256); 
      // retrieve data on return 
      cropIntent.putExtra("return-data", true); 
      // start the activity - we handle returning in onActivityResult 
      startActivityForResult(cropIntent, CROP_PIC); 
     } 
     // respond to users whose devices do not support the crop action 
     catch (ActivityNotFoundException anfe) { 
      Toast toast = Toast 
        .makeText(this, "This device doesn't support the crop action!", Toast.LENGTH_SHORT); 
      toast.show(); 
     } 
    }

Versuchen Sie, diese

   Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 

       mImageCaptureUri = Uri.fromFile(new File(Environment 
         .getExternalStorageDirectory(), "tmp_avatar_" 
         + String.valueOf(System.currentTimeMillis()) 
         + ".jpg")); 

       intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, 
         mImageCaptureUri); 

       intent.setData(mImageCaptureUri); 
       intent.putExtra("outputX", 200); 
       intent.putExtra("outputY", 200); 
       intent.putExtra("aspectX", 1); 
       intent.putExtra("aspectY", 1); 
       intent.putExtra("scale", true); 
       intent.putExtra("return-data", true);
