이미지가 이미지보기에 표시되지 않습니다.

Question

버튼을 클릭하여 사진을 찍고 이미지 뷰에 표시합니다. Google Nexus에서 작동합니다. 하지만 삼성 탭과 Micromax 캔버스 HD에서 작동하지 않는 이유는 무엇입니까?

내 버튼 클릭 코드 :

 CAMERA_PIC_REQUEST = 100; 

    String path = Environment.getExternalStorageDirectory() 
      + "/MySampleApp/image.jpg"; 

      File file = new File(path); 
      Uri outputFileUri = Uri.fromFile(file); 

      Intent cameraIntent = new Intent(
        android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
      cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri); 
      startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST); 

onActivityResult를 코드 :

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

왜이 코드는 삼성과 micromax 작동하지 않습니다 manifest.xml

에서

  BitmapFactory.Options options = new BitmapFactory.Options(); 
     options.inSampleSize = 4; 
       Bitmap bitmap = BitmapFactory.decodeFile(path, 
          options); 
        mImageView.setImageBitmap(bitmap); 

권한?

올바른 코드가 맞지 않습니까?

아무도 도와주세요.

Answer 1

devices..use micromax에서 작동이 코드를 사용해보십시오이

btn.setOnClickListener(new OnClickListener(){ 

      @Override 
      public void onClick(View arg0) 
      { 
       CAMERA_PIC_REQUEST = 100; 
       Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
       startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST); 
      } 
     }); 

그리고 배포하는 동안

@Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) 
    { 
    super.onActivityResult(requestCode, resultCode, data); 
     if (requestCode == CAMERA_PIC_REQUEST && resultCode == RESULT_OK) { 
     Bitmap photo = (Bitmap) data.getExtras().get("data"); 
     mImageView.setImageBitmap(photo); 
     } 
    }
