アンドロイドで画像を選択して切り抜いたときの画質の変化（ぼかし）

Question

ギャラリーから画像を選択して画像を選択するアンドロイドでコードを実装しましたが、その画像は画像に見えますが切り抜かれた画像は非常にぼやけて、そのまま切り抜いた画像を表示する方法

ここで

私のコードです：

ImageSelecter.java

public class ImageSelecter extends Activity { 

private final int GALLERY_ACTIVITY_CODE=200; 
private final int RESULT_CROP = 400; 
String picturePath; 
ImageView image_capture1; 
Button btn_choose; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    btn_choose=(Button)findViewById(R.id.choose_btn); 
    image_capture1=(ImageView)findViewById(R.id.img); 
    btn_choose.setOnClickListener(new View.OnClickListener() { 
     public void onClick(View v) { 
      //Start Activity To Select Image From Gallery 
      Intent gallery_Intent = new Intent(getApplicationContext(), GalleryUtil.class); 
      startActivityForResult(gallery_Intent, GALLERY_ACTIVITY_CODE); 
      } 
     }); 

     } 

@Override 
public void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 
    if (requestCode == GALLERY_ACTIVITY_CODE) { 
     if(resultCode == Activity.RESULT_OK){ 
      picturePath = data.getStringExtra("picturePath"); 
      //perform Crop on the Image Selected from Gallery 
      performCrop(picturePath); 
     } 
    } 

    if (requestCode == RESULT_CROP) { 
     if(resultCode == Activity.RESULT_OK){ 
      Bundle extras = data.getExtras(); 
      Bitmap selectedBitmap = extras.getParcelable("data"); 

      // Set The Bitmap Data To ImageView 
      image_capture1.setImageBitmap(selectedBitmap); 
       image_capture1.setScaleType(ImageView.ScaleType.FIT_XY); 
     } 
    } 
} 

private void performCrop(String picUri) { 
    try { 
     //Start Crop Activity 

     Intent cropIntent = new Intent("com.android.camera.action.CROP"); 
     // indicate image type and Uri 
     File f = new File(picUri); 
     Uri contentUri = Uri.fromFile(f); 

     cropIntent.setDataAndType(contentUri, "image/*"); 
     // set crop properties 
     cropIntent.putExtra("crop", "true"); 
     // indicate aspect of desired crop 
     cropIntent.putExtra("aspectX", 1); 
     cropIntent.putExtra("aspectY", 1); 
     // indicate output X and Y 
     cropIntent.putExtra("outputX", 280); 
     cropIntent.putExtra("outputY", 280); 

     // retrieve data on return 
     cropIntent.putExtra("return-data", true); 
     // start the activity - we handle returning in onActivityResult 
     startActivityForResult(cropIntent, RESULT_CROP); 
    } 
    // respond to users whose devices do not support the crop action 
    catch (ActivityNotFoundException anfe) { 
     // display an error message 
     String errorMessage = "your device doesn't support the crop action!"; 
     Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT); 
     toast.show(); 
    } 
} 
} 

そして

GalleryUは、次のようにギャラリークラスを表示するためのクラスですtil.java

public class GalleryUtil extends Activity { 
    private final static int RESULT_SELECT_IMAGE = 100; 
    public static final int MEDIA_TYPE_IMAGE = 1; 
    private static final String TAG = "GalleryUtil"; 

    String mCurrentPhotoPath; 
    File photoFile = null; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    try{ 
     //Pick Image From Gallery 
     Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); 
     startActivityForResult(i, RESULT_SELECT_IMAGE); 
    }catch(Exception e){ 
     e.printStackTrace(); 
    } 
} 

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 

    switch(requestCode){ 
     case RESULT_SELECT_IMAGE: 

      if (resultCode == Activity.RESULT_OK && data != null && data.getData() != null) { 
       try{ 
        Uri selectedImage = data.getData(); 
        String[] filePathColumn = {MediaStore.Images.Media.DATA }; 
        Cursor cursor = getContentResolver().query(selectedImage, 
          filePathColumn, null, null, null); 
        cursor.moveToFirst(); 
        int columnIndex = cursor.getColumnIndex(filePathColumn[0]); 
        String picturePath = cursor.getString(columnIndex); 
        cursor.close(); 

        //return Image Path to the Main Activity 
        Intent returnFromGalleryIntent = new Intent(); 
        returnFromGalleryIntent.putExtra("picturePath",picturePath); 
        setResult(RESULT_OK,returnFromGalleryIntent); 
        finish(); 
       }catch(Exception e){ 
        e.printStackTrace(); 
        Intent returnFromGalleryIntent = new Intent(); 
        setResult(RESULT_CANCELED, returnFromGalleryIntent); 
        finish(); 
       } 
      }else{ 
       Log.i(TAG,"RESULT_CANCELED"); 
       Intent returnFromGalleryIntent = new Intent(); 
       setResult(RESULT_CANCELED, returnFromGalleryIntent); 
       finish(); 
      } 
      break; 
    } 
} 
    } 

トリミングした画像をそのまま表示するようにしてください。

Answer 1

ImageView.ScaleType.FIT_XYをImageView.ScaleType.CENTER_INSIDEに変更してください。

またはFIT_CENTER/CENTER_CROP/CENTERのような他の適切なScaleType。
