將圖像添加到文件夾中的SD卡

Question

每次在拍攝圖像的文件夾創建部分工作正常，但如果我添加的文件夾的創建和圖像邏輯保存的圖像不會被添加到該文件夾​​

photoButton.setOnClickListener(new View.OnClickListener() 
{ 
@Override 
public void onClick(View v) 
{ 
cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
startActivityForResult(cameraIntent, CAMERA_REQUEST); 
} 
}); 
protected void onActivityResult(int requestCode, int resultCode, Intent data) 
{ 
if (requestCode == CAMERA_REQUEST && resultCode != RESULT_CANCELED) 
{ 
folder = new File(Environment.getExternalStorageDirectory() + File.separator+"folder/");       

if(!folder.exists()) 

     { 
      folder.mkdirs(); 
      Log.d("SDcard", "Folder created"); 
     } 
     else 
     { 
      Log.d("SDCard", "Folder already exists"); 
     } 
File file = new File(Environment.getExternalStorageDirectory() +  File.separator +"folder/"); 
     Uri photoPath = Uri.fromFile(file); 
     cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoPath); ` 
     } 
     } 

的onclick（）直接它顯示錯誤消息：「未能提供結果信息」

public void saveBitmapToFile(Bitmap bmp) { 

     File mAppBaseDir; 
     if (isExternalStorageWritable()) 
      mAppBaseDir = new File(Environment.getExternalStorageDirectory(), "FolderName"); 
     else 
      mAppBaseDir = new File(getApplicationContext().getFilesDir().getParent()).getAbsoluteFile(); 

     if (!mAppBaseDir.exists()) { 
      mAppBaseDir.mkdirs(); 
     } 
     File imageDir = new File(mAppBaseDir, "Profile"); 
     if (!imageDir.exists()) 
      imageDir.mkdirs(); 
     File file = new File(imageDir + "/" + "profile.png"); 
     if (file.exists()) { 
      file.delete(); 
     } 
     try { 
      writeBytesToFile(file, bitmapToByte(bmp)); 

     } catch (IOException e) { 
      // show alert for retry choose photo 
      e.printStackTrace(); 
     } 
    } 



public void writeBytesToFile(File file, byte[] bytes) throws IOException { 
     BufferedOutputStream bos = null; 

     try { 
      FileOutputStream fos = new FileOutputStream(file.getPath()); 
      bos = new BufferedOutputStream(fos); 
      bos.write(bytes); 
     } catch (Exception e) { 
      Log.e("", e.getMessage()); 
     } finally { 
      if (bos != null) { 
       try { 
        bos.flush(); 
        bos.close(); 
       } catch (Exception e) { 
        Log.e("", e.getMessage()); 
       } 
      } 
     } 
    } 

public byte[] bitmapToByte(Bitmap bitmapFinally) { 
     ByteArrayOutputStream stream = new ByteArrayOutputStream(); 
     bitmapFinally.compress(Bitmap.CompressFormat.PNG, 100, stream); 
     byte[] byteArray = stream.toByteArray(); 
     return byteArray; 
    }

我回答這個問題，根據你的c omment 「請您詳細說明」。 CMIIW：

photoButton.setOnClickListener(new View.OnClickListener() { 
    @Override 
    public void onClick(View v) { 
     cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
     folder = new File(Environment.getExternalStorageDirectory() + File.separator + "folder/"); 

     if (!folder.exists()) 

     { 
      folder.mkdirs(); 
      Log.d("SDcard", "Folder created"); 
     } else { 
      Log.d("SDCard", "Folder already exists"); 
     } 
     File file = new File(Environment.getExternalStorageDirectory() + File.separator + "folder/"); 
     Uri photoPath = Uri.fromFile(file); 
     cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoPath); 

     startActivityForResult(cameraIntent, CAMERA_REQUEST); 
    } 
}); 

「伊夫宣佈cameraIntent對象onCreate（）方法之前」
這是沒問題的，但onActivityResult會觸發你調用startActivityForResult後，再意圖不會有多餘的你給
