Question

您好我在主片段中使用了带有fragmnets的viewPager。＆＃xA;我正在尝试从图库或摄像头获取图像到位图，但是在选择照片和startActivityForResult后它没有捕获到onActivityResult ...

＆＃xA;＆＃xA;

这里是我如何调用startActivityForResult：

＆＃xA;＆＃xA;

  private void setAvatarDialog（）{＆＃xA; final CharSequence [] options = {“从画廊中选择”，“拍照”};＆＃xA;＆＃xA; String title = getString（R.string.alertDialog_editProfile_updateAvatar_title）;＆＃xA; String negative = getString（R.string.alertDialog_editProfile_updateAvatar_negative）;＆＃xA;＆＃xA; AlertDialog.Builder builder = new AlertDialog.Builder（getActivity（））;＆＃xA; builder.setTitle（标题）;＆＃XA; builder.setItems（options，new DialogInterface.OnClickListener（）{＆＃xA; @Override＆＃xA; public void onClick（DialogInterface dialog，int which which）{＆＃xA; if（options [which] .equals（options [0] ））{＆＃xA; mIntent = new Intent（Intent.ACTION_PICK，MediaStore.Images.Media.EXTERNAL_CONTENT_URI）;＆＃xA; mIntent.setType（“image / *”）;＆＃xA; startActivityForResult（Intent.createChooser（ mIntent，“选择文件”），SELECT_FILE）;＆＃xA;} else if（options [which] .equals（options [1]））{＆＃xA; mIntent = new Intent（MediaStore.ACTION_IMAGE_CAPTURE）;＆＃xA ; startActivityForResult（mIntent，REQUEST_CAMERA）;＆＃xA;}＆＃xA; dialog.dismiss（）;＆＃xA;}＆＃xA;}）;＆＃xA; builder.setNegativeButton（否定，新的DialogInterface.OnClickListener（）{＆＃xA; @Override＆＃xA; public void onClick（DialogInterface对话框，int which which）{＆＃xA; dialog.dismiss（）;＆＃xA;}＆＃ xA;}）;＆＃xA; builder.show（）;＆＃XA; }＆＃xA;

＆＃xA;＆＃xA;

这是我的onActivityResult：

＆＃xA;＆＃xA;

  @ Override＆ #xA; public void onActivityResult（int requestCode，int resultCode，Intent data）{＆＃xA; super.onActivityResult（requestCode，resultCode，data）;＆＃xA; if（resultCode == Activity.RESULT_OK）{＆＃xA; if（requestCode == REQUEST_CAMERA）{＆＃xA; resultCamera（数据）;＆＃XA; } else if（requestCode == SELECT_FILE）{＆＃xA; resultGallery（数据）;＆＃XA; }＆＃XA; }＆＃XA; ＆＃xA;

＆＃xA;＆＃xA;

请问任何想法？

Answer 1

当我的ParentFragment包含一个包含3个不同片段（子节点）的ViewPager并且其中一个子片段启动了一个活动时，这个解决方案对我有用。

您可以在getParentFragment().startActivityForResult

的孩子中打开活动

一旦该活动完成，它将在ParentFragment中调用onActivityResult，其中我覆盖该方法以调用3个孩子中的每一个onActivityResult

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    for (Fragment fragment : getChildFragmentManager().getFragments()) {
        fragment.onActivityResult(requestCode, resultCode, data);
    }
}

Answer 2

您需要确保为结果启动的活动也会返回结果。例如，在图片捕获Activity中，Activity结束，包括

    Intent intent = new Intent();
    //intent.putExtra
    intent.putExtra(getString(R.string.MY_RESULT_CODE), data);
    setResult(RESULT_OK, intent);
    finish(); //Ends the current activity. 
    //After this, onActivityResult of the activity that started this one will be called

所有表明它是一个问题，当ViewPager中的片段时，我有同样的问题。

Answer 4

这对我有用。

// Parent Fragment
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    getTargetFragment().onActivityResult(requestCode, resultCode, data);
}

// In Child Fragment
public void pick() {
        Intent intent = new Intent();
        intent.setType("image/*");
        intent.setAction(Intent.ACTION_GET_CONTENT);

        // Note followings two lines.
        getParentFragment().startActivityForResult(Intent.createChooser(intent, "Select"), 1);
        getParentFragment().setTargetFragment(this,1);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        Log.d("DEBUG","ONE1");
        if (requestCode == PICK_IMAGE_REQUEST && resultCode == Activity.RESULT_OK && data != null && data.getData() != null) {
            Log.d("DEBUG","TWO");
            Uri uri = data.getData();
            try {
                Log.d("DEBUG","THREE");
                Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContext().getContentResolver(), uri);
                // Log.d(TAG, String.valueOf(bitmap));
                Log.d("DEBUG","FOUR");
                ImageView imageView = (ImageView) yourLayoutView.findViewById(R.id.yourImageView);
                Log.d("DEBUG","FIVE");
                imageView.setImageBitmap(bitmap);
                Log.d("DEBUG", "SIX");
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
}

onActivityResult不从viewPager片段调用
