图片不显示在图像查看

Question

我打开相机按钮单击并拍照并显示它在imageview中。它在Google Nexus中工作。但它不适用于Samsung Tab和Micromax canvas HD，为什么？

我的按钮点击代码：

 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); 

OnActivityResult代码：

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

权限在manifest.xml中

<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" /> 

为什么没有在三星和Micromax的工作代码？

这是正确的代码是不是？

任何人请帮助我吗？

Answer 1

试试这个

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); 
      } 
     }); 

而且

@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); 
     } 
    }

试试这个代码将在工作福邦这devices..use URI

btnGallery.setOnClickListener(new OnClickListener() 
      { 

       @Override 
       public void onClick(View v) 
       { 
        Intent intent = new Intent(); 
        intent.setType("image/*"); 
        intent.setAction(Intent.ACTION_GET_CONTENT); 
        pop.dismiss(); 
        startActivityForResult(Intent.createChooser(intent, "Select Picture"), StaticMembers.galleryRequestCode); 
       } 
      }); 
      ImageView btnCamera = (ImageView) pop.findViewById(R.id.ivCamera); 
      btnCamera.setOnClickListener(new OnClickListener() 
      { 

       @Override 
       public void onClick(View v) 
       { 

        //With Camera Utils 
        pop.dismiss(); 
        outpuUri = CameraUtil.startCam(yourActivity.this);

      } 
      else

     } 
     if (imgPath != null) 
     { 
      showConfrirmDialog(imgPath, time); 
     } 

    }

     } 


     public static File getImageFolderFile()
