我知道这个问题已经问了很多次在这个论坛。但我仍然无法得到解决方案。 基本上在我的应用程序,我打电话内置相机意图,捕获图像,并在ImageView中显示位图并将其存储在SD卡中。现在,我在我的文件夹中获得的图像尺寸很小,就像缩略图一样。从相机捕获的图像是不是全尺寸存储

我的代码是

 Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
     startActivityForResult(Intent.createChooser(cameraIntent, "Select picture"), CAMERA_REQUEST); 

protected void onActivityResult(int requestCode, int resultCode, Intent data) { 

      try { 
     if (requestCode == CAMERA_REQUEST) { 
      Bitmap photo = (Bitmap) data.getExtras().get("data"); 

      if (photo != null) { 
       imageView.setImageBitmap(photo); 
      } 

      // Image name 

      final ContentResolver cr = getContentResolver(); 
      final String[] p1 = new String[] { MediaStore.Images.ImageColumns._ID, 
        MediaStore.Images.ImageColumns.DATE_TAKEN }; 
      Cursor c1 = cr.query(
        MediaStore.Images.Media.EXTERNAL_CONTENT_URI, p1, null, 
        null, p1[1] + " DESC"); 
      if (c1.moveToFirst()) { 
       String uristringpic = "content://media/external/images/media/" + c1.getInt(0); 
       Uri newuri = Uri.parse(uristringpic); 

       String snapName = getRealPathFromURI(newuri); 

       Uri u = Uri.parse(snapName); 

       File f = new File("" + u); 
       String fileName = f.getName(); 

       editTextPhoto.setText(fileName); 
       checkSelectedItem = true; 

       ByteArrayOutputStream bos = new ByteArrayOutputStream(); 
       photo.compress(CompressFormat.PNG, 0 /* ignored for PNG */, bos); 
       byte[] bitmapdata = bos.toByteArray(); 

       // Storing Image in new folder 
       StoreByteImage(mContext, bitmapdata, 100, fileName); 

       sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, 
         Uri.parse("file://" + Environment.getExternalStorageDirectory()))); 

       // Delete the image from the Gallery 

       getContentResolver().delete(newuri, null, null); 

      } 
      c1.close(); 

      } 
     } catch (NullPointerException e) { 
      System.out.println("Error in creating Image." + e); 

     } catch (Exception e) { 
      System.out.println("Error in creating Image." + e); 
     } 
     System.out.println("*** End of onActivityResult() ***"); 
    } 

     public String getRealPathFromURI(Uri contentUri) { 
      String[] proj = { MediaStore.Images.Media.DATA }; 
      Cursor cursor = managedQuery(contentUri, proj, null, null, null); 
      int column_index = cursor 
        .getColumnIndexOrThrow(MediaStore.Images.Media.DATA); 
      cursor.moveToFirst(); 
      return cursor.getString(column_index); 
     } 

     public boolean StoreByteImage(Context pContext, byte[] pImageData, 
       int pQuality, String pExpName) { 

      String nameFile = pExpName; 
      // File mediaFile = null; 
      File sdImageMainDirectory = new File(
        Environment.getExternalStorageDirectory() + "/pix/images"); 
      FileOutputStream fileOutputStream = null; 
      try { 

       BitmapFactory.Options options = new BitmapFactory.Options(); 
       options.inSampleSize = 0; 
       Bitmap myImage = BitmapFactory.decodeByteArray(pImageData, 0, 
         pImageData.length, options); 
       if (!sdImageMainDirectory.exists()) { 
        sdImageMainDirectory.mkdirs(); 
       } 

       sdImageMainDirectory = new File(sdImageMainDirectory, nameFile); 
       sdImageMainDirectory.createNewFile(); 

       fileOutputStream = new FileOutputStream(
         sdImageMainDirectory.toString()); 
       BufferedOutputStream bos = new BufferedOutputStream(
         fileOutputStream); 
       myImage.compress(CompressFormat.JPEG, pQuality, bos); 

       bos.flush(); 
       bos.close(); 

      } catch (FileNotFoundException e) { 
       Toast.makeText(pContext, e.getMessage(), Toast.LENGTH_LONG).show(); 
       e.printStackTrace(); 
      } catch (IOException e) { 
       Toast.makeText(pContext, e.getMessage(), Toast.LENGTH_LONG).show(); 
       e.printStackTrace(); 
      } 

和ImageView的main.xml中是

<ImageView 
     android:id="@+id/test_image" 
     android:src="@drawable/gray_pic" 
     android:layout_width="180dp" 
     android:layout_height="140dp" 
     android:layout_below="@id/edit2" 
     android:layout_toRightOf="@id/edit3" 
     android:layout_alignParentRight="true" 
     android:layout_marginTop="7dp" 
     android:layout_marginBottom="5dp" 
     android:layout_marginLeft="7dp" 
     android:layout_marginRight="7dp" 
     /> 

有了这个代码让我的文件夹中的小尺寸的ImageView和形象店。 如果我添加intent.putExtra,那么在ImageView中既不会捕获图像,也不会在新文件夹中创建图像。

Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 

String path = Environment.getExternalStorageDirectory().getAbsolutePath(); 
path += "/myFolder/myPicture.jpg"; 
File file = new File(path); 
Uri outputFileUri = Uri.fromFile(file); 
cameraIntent.putExtra("output", outputFileUri); 
startActivityForResult(Intent.createChooser(cameraIntent, "Select Picture"), CAMERA_REQUEST); 
} 

不知道我在哪里来袭.. 任何关于这帮助将不胜感激。

使用相机意图为:

Intent photoPickerIntent= new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
        photoPickerIntent.putExtra(MediaStore.EXTRA_OUTPUT, getTempFile()); 
        photoPickerIntent.putExtra("outputFormat", Bitmap.CompressFormat.JPEG.toString()); 
        photoPickerIntent.putExtra("return-data", true); 
        startActivityForResult(Intent.createChooser(photoPickerIntent,"Select Picture"),TAKE_PICTURE); 

// getTempFile()

private Uri getTempFile() { 
    //   if (isSDCARDMounted()) { 

      File root = new File(Environment.getExternalStorageDirectory(), "My Equip"); 
      if (!root.exists()) { 
       root.mkdirs(); 
      } 
      Log.d("filename",filename); 
      File file = new File(root,filename+".jpeg"); 

        muri = Uri.fromFile(file); 
        photopath=muri.getPath(); 
        Item1.photopaths=muri.getPath(); 

      Log.e("getpath",muri.getPath()); 
       return muri; 
    //   } else { 
    //   return null; 
       } 
       //} 
      private boolean isSDCARDMounted(){ 
       String status = Environment.getExternalStorageState(); 
       if (status.equals(Environment.MEDIA_MOUNTED)) 
       return true; 
       else 
       return false; 

       } 

,并检查您的文件夹,点击缩略图,它会显示实际图像

感谢ABHI的答复。但我仍然得到相同的结果。该文件夹本身没有创建。我的outputFileUri在上面的代码中是否正确?而且还没有在imageview中获取图像缩略图...其实我正在使用StoreByteImage()方法来创建文件夹和存储图像。该方法的任何更改要完成? – Shrikant 2012-01-28 11:47:22

看到我编辑的问题,试试那种方式 – Abhi 2012-01-28 12:22:29
