发生了什么事?无法从片段中选取图片库图片

我想从图库中选择一张照片,然后将该照片设置为我的ImageButton的图像。这应该是非常简单的,但不知何故,我搞砸了。这就是我如何想:我在其中设置我的标签,我的ImageButton的片段:

@Override 
public void onActivityCreated(@Nullable Bundle savedInstanceState) { 
    super.onActivityCreated(savedInstanceState); 

    TabHost host = (TabHost)getView().findViewById(R.id.tabHost); 
    host.setup(); 

    //Tab 1 
    TabHost.TabSpec spec = host.newTabSpec("Foto"); 
    spec.setContent(R.id.tab1); 
    spec.setIndicator("Foto"); 
    host.addTab(spec); 

    //Tab 2 
    spec = host.newTabSpec("Sentimento"); 
    spec.setContent(R.id.tab2); 
    spec.setIndicator("sentimento"); 
    host.addTab(spec); 

    //Tab 3 
    spec = host.newTabSpec("Medição"); 
    spec.setContent(R.id.tab3); 
    spec.setIndicator("Medição"); 
    host.addTab(spec); 

    cancelBtn = (ImageButton)getView().findViewById(R.id.cancel_post_btn); 
    saveBtn = (ImageButton)getView().findViewById(R.id.save_post_btn); 
    insertPostText = (EditText)getView().findViewById(R.id.insert_post_text); 

    postImageBtn = (ImageButton)getView().findViewById(R.id.post_img_btn); 
    postImageBtn.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      Intent galleryIntent = new Intent(Intent.ACTION_GET_CONTENT); 
      galleryIntent.setType("image/*"); 
      startActivityForResult(galleryIntent, GALLERY_REQUEST); 
     } 
    }); 
} 

这是我onActivityResult方法与我的日志:

@Override 
public void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 
    Log.d("---------", "activity result"); 
    if (requestCode == GALLERY_REQUEST && requestCode == getActivity().RESULT_OK){ 
     Log.d("-----------", "result ok"); 
     Uri imageUri = data.getData(); 
     postImageBtn.setImageURI(imageUri); 
    } else { 
     Log.d("-----------", "result not ok"); 
     Log.d("----------", String.valueOf(requestCode)); 
     Log.d("----------", String.valueOf(RESULT_OK)); 
    } 
} 

这些都是我的日志结果:

03-07 14:23:50.767 30717-30717/? D/---------: activity result 
03-07 14:23:50.767 30717-30717/? D/-----------: result not ok 
03-07 14:23:50.767 30717-30717/? D/----------: 1 
03-07 14:23:50.767 30717-30717/? D/----------: -1 

最后,这是我的Android清单:

<uses-permission android:name="android.permission.CAMERA" /> 
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> 

你们有什么想法,为什么会发生这种情况?

不画廊开放?应用程序崩溃? – tahsinRupam

是的,画廊打开,不,应用程序不会崩溃。我无法设法更新我的ImageButton,但我认为这是因为我的RESULT_OK等于-1 – Rob

这让我感到很惭愧,但我仍然需要张贴以防万一有人达到这个问题的答案。我应该是比较

getActivity().RESULT_OK 

resultCode 

,所以这是它是如何工作现在:

@Override 
public void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 
Log.d("---------", "activity result"); 
if (requestCode == GALLERY_REQUEST && resultCode == getActivity().RESULT_OK){ 
    Log.d("-----------", "result ok"); 
    Uri imageUri = data.getData(); 
    postImageBtn.setImageURI(imageUri); 
} else { 
    Log.d("-----------", "result not ok"); 
    Log.d("----------", String.valueOf(requestCode)); 
    Log.d("----------", String.valueOf(RESULT_OK)); 
} 
}

试着改变你的画廊意图是:

Intent pickPhoto = new Intent(Intent.ACTION_PICK, 
       android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); 
     if (isAdded() && pickPhoto.resolveActivity(getActivity().getPackageManager()) != null) 
      startActivityForResult(pickPhoto, requestCode); 

它采用了ContentProvider风格机甲
