无法从片段中选择图库图像

Unable to pick gallery image from Fragment

怎么了?

我正在尝试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。这应该是非常直截了当的,但不知何故我把它搞砸了。这就是我正在尝试的方式:我有一个片段,我在其中设置了我的选项卡和我的 ImageButton:

@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);
        }
    });
}

这是我的 onActivityResult 方法和我的日志:

@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" />

你们知道为什么会这样吗?

尝试将您的画廊意图更改为:

 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);

使用 ContentProvider 风格的机械

这让我感到很惭愧,但我仍然需要 post 回答,以防有人遇到这个问题。我应该比较

getActivity().RESULT_OK

resultCode

现在是这样工作的:

@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));
}
}
