從圖庫返回后，未在Fragment中調用onActivityResult

Question

在我的片段中，我從畫廊中選擇照片

在Manifest.xml中

   <uses-permission android:name="android.permission.CAMERA"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_GPS"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.CALL_PHONE"/>
<uses-permission android:name="android.permission.GET_TASKS"/>
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

在此之前，我的應用程序顯示權限對話框。 我按允許

public class EditProfileFragment extends androidx.fragment.app.Fragment {
 private void choosePhotoFromGallery() {
        Intent photoPickerIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
        photoPickerIntent.setType("image/*");
        startActivityForResult(photoPickerIntent, SELECT_PHOTO);
}

但是方法

 @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (BuildConfig.DEBUG)
            Log.d(TAG, "onActivityResult_requestCode = " + requestCode + ", resultCode = " + resultCode + ", data = "
                    + AndroidUtil.intent2String(data));

返回我的應用后無法調用 Fragment

不打印文本： onActivityResult_requestCode

但是方法Activity中的 onActivityResult（int requestCode，int resultCode，Intent data）調用。 但是我需要分段調用此方法。

在這里請求權限對話框：

  private boolean checkAndRequestPermissions() {
        int writeExternalStorage = ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.WRITE_EXTERNAL_STORAGE);
        int readExternalStorage = ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.READ_EXTERNAL_STORAGE);
        int camera = ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.CAMERA);
        List<String> listPermissionsNeeded = new ArrayList<>();
        if (writeExternalStorage != PackageManager.PERMISSION_GRANTED) {
            listPermissionsNeeded.add(Manifest.permission.WRITE_EXTERNAL_STORAGE);
        }
        if (readExternalStorage != PackageManager.PERMISSION_GRANTED) {
            listPermissionsNeeded.add(Manifest.permission.READ_EXTERNAL_STORAGE);
        }
        if (camera != PackageManager.PERMISSION_GRANTED) {
            listPermissionsNeeded.add(Manifest.permission.CAMERA);
        }
        if (BuildConfig.DEBUG)
            Log.d(TAG, "checkAndRequestPermissions_listPermissionsNeeded(" + listPermissionsNeeded.size() + ")");
        if (!listPermissionsNeeded.isEmpty()) {
            if (BuildConfig.DEBUG)
                Log.d(TAG, "checkAndRequestPermissions_REQUEST_WRITE_EXTERNAL_STORAGE_REQ_CODE");
            ActivityCompat.requestPermissions(getActivity(), listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()])
                    , WRITE_EXTERNAL_STORAGE_REQ_CODE);
            return false;
        }
        return true;
    }

Answer 1

將其放在活動結果中的活動中

   Fragment fragment = getSupportFragmentManager().findFragmentById(R.id.frameLayout);
        fragment.onActivityResult(requestCode, resultCode, data);

它要做的是將片段的片段稱為onActivityResult。 這樣片段中就會有選擇數據

內部片段開始活動以獲取結果

getActivity().startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);

現在處於活動狀態

   @Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        Fragment fragment = getSupportFragmentManager().findFragmentById(R.id.frameLayout);
        fragment.onActivityResult(requestCode, resultCode, data);
    }

內部片段

 @Override
    public void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        //  super.onActivityResult(requestCode, resultCode, data);
        Log.d(TAG, "Activit Result");
        if (resultCode == -1) {
        }
}

希望會有所幫助

Answer 2

由於您是從片段呼叫，因此請嘗試此

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    Fragment fragment = getSupportFragmentManager().findFragmentById(R.id.your_tag);
    fragment.onActivityResult(requestCode, resultCode, data);
}
