從圖庫中選擇一張圖片dosen't work

我想從圖庫中拍攝一張照片，我使用此代碼。
從圖庫中選擇一張圖片dosen't work

該代碼適用於sumsung s4設備中的某張照片，但不適用於sumsung a7。

我想創建一個代碼，將適用於所有設備。

public class SignUpPersonalUserStep5 extends Fragment { 


public SignUpPersonalUserStep5(PersonalProfil profil) { 
    this.profil = profil; 
} 

PersonalProfil profil; 
public static final int RESULT_LOAD_PHOTO = 3; 
ImageView signUpPhoto; 
String ImageDecodableString; 
FloatingActionButton button; 


@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
         Bundle savedInstanceState) { 

    View view = inflater.inflate(R.layout.step5_sign_up, container, false); 
    signUpPhoto = (ImageView) view.findViewById(R.id.signUpPhoto); 
    signUpPhoto.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      Intent galleryIntent = new Intent(Intent.ACTION_PICK, 
        MediaStore.Images.Media.EXTERNAL_CONTENT_URI); 
      startActivityForResult(galleryIntent, RESULT_LOAD_PHOTO); 

     } 
    }); 

    button = (FloatingActionButton) view.findViewById(R.id.step5Button); 

    button.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 

      FragmentManager manager = getActivity().getSupportFragmentManager(); 

      SignUpPersonalUserStep4 signUpStep4 = new SignUpPersonalUserStep4(profil); 
      FragmentTransaction transaction = manager.beginTransaction(); 
      transaction.addToBackStack(""); 
      transaction.setCustomAnimations(R.anim.toastox_sheet_show, R.anim.toastox_sheet_hide); 
      transaction.replace(R.id.signUpForFragment, signUpStep4); 
      transaction.commit(); 


     } 
    }); 

    return view; 
} 

@Override 
public void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 
    try { 
     // When an Image is picked 
     if (requestCode == RESULT_LOAD_PHOTO && resultCode == RESULT_OK 
       && null != data) { 
      Uri selectedImage = data.getData(); 
      String[] filePathColumn = {MediaStore.Images.Media.DATA}; 
      // Get the cursor 
      Cursor cursor = getActivity().getContentResolver().query(selectedImage, 
        filePathColumn, null, null, null); 
      // Move to first row 
      cursor.moveToFirst(); 
      int columnIndex = cursor.getColumnIndex(filePathColumn[0]); 
      ImageDecodableString = cursor.getString(columnIndex); 
      cursor.close(); 
      Log.d("nizar",ImageDecodableString); 
      signUpPhoto.setImageBitmap(BitmapFactory 
        .decodeFile(ImageDecodableString)); 
      // ImageDecodableString = Base64.encodeToString(ImageDecodableString.getBytes(), Base64.DEFAULT); 
      profil.setImage(ImageDecodableString); 

     } 
    } catch (Exception e) { 
     Toast.makeText(getActivity(), "Something went wrong", Toast.LENGTH_LONG) 
       .show(); 
    } 


}}

我想說的是，數據不是空的。
請讓我知道你在想什麼
非常感謝！

Android操作系統版本的三星A7？ – Aryan

Android版本6.0.1 –

請在下面檢查我的答案？ – Aryan

試試這個代碼：

private void requestPermission() { 
     if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) { 
      requestPermissions(new String[]{android.Manifest.permission.WRITE_EXTERNAL_STORAGE}, REQUEST_WRITE_PERMISSION); 
     } else { 
      Intent intent = new Intent(); 
      intent = new Intent(Intent.ACTION_PICK, 
      android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); 
      startActivityForResult(intent, PICK_IMAGE_REQUEST); 
     } 
    }

這對我有用 Uri Selected_Image_Uri = data.getData（）; ImageView imageView =（ImageView）findViewById（R.id.loadedimg）; imageView.setImageURI（Selected_Image_Uri）; 謝謝 –

如果問題解決了。然後接受我的答案。 –

我覺得Build.VERSION.SDK_INT> = Build.VERSION_CODES.M不是Build.VERSION_CODES.N – Aryan

如果您的目標是Android SDK> = 23，您需要在用戶運行時獲得權限（如果用戶擁有Android OS Marshmallow或更高版本）。

問題看起來類似http://stackoverflow.com/questions/42133758/file-listfiles-returns-null-when-it-shouldnt/42133977#42133977 – Aryan

這對我工作Uri Selected_Image_Uri = data.getData（）; ImageView imageView =（ImageView）findViewById（R.id.loadedimg）; imageView.setImageURI（Selected_Image_Uri）;謝謝 –

你的Android目標SDK是什麼？ – Aryan

這帶來了文件的應用程序。爲了讓用戶使用起來也有可能被安裝任何應用程序畫廊：

Intent getIntent = new Intent(Intent.ACTION_GET_CONTENT); 
    getIntent.setType("image/*"); 
    Intent pickIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); 
    pickIntent.setType("image/*"); 
    Intent chooserIntent = Intent.createChooser(getIntent, "Select Image"); 
    chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, new Intent[]{pickIntent}); 
    startActivityForResult(chooserIntent, PICK_IMAGE);
