Я хочу использовать метод onActivityResult в Adapter, но после поиска по переполнению стека я обнаружил, что должен создать интерфейс для onActivityResult, но я не знаю, как это сделать, и обработать метод onActivityResult для работы в соответствии с моими потребностями.
Вот мой класс адаптера.
public class PosterAdapter extends RecyclerView.Adapter<PosterAdapter.PosterViewHolder> {
private static final String TAG = "resPoster";
private ArrayList<Poster> posterArrayList;
private Context context;
public PosterAdapter(ArrayList<Poster> posterArrayList, Context context) {
this.posterArrayList = posterArrayList;
this.context = context;
}
@NonNull
@Override
public PosterViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
View itemView = LayoutInflater.from(viewGroup.getContext())
.inflate(R.layout.sending_image_layout, viewGroup, false);
return new PosterViewHolder(itemView);
}
@Override
public void onBindViewHolder(@NonNull PosterViewHolder posterViewHolder, int i) {
posterViewHolder.imageViewDownload.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
posterViewHolder.relativeLayoutImage.setDrawingCacheEnabled(true);
Bitmap bitmap = Bitmap.createBitmap(posterViewHolder.relativeLayoutImage.getDrawingCache());
posterViewHolder.relativeLayoutImage.setDrawingCacheEnabled(false);
FileOutputStream outStream = null;
File sdCard = Environment.getExternalStorageDirectory();
File dir = new File(sdCard.getAbsolutePath() + "/providers");
dir.mkdirs();
String fileName = String.format("%d.jpg", System.currentTimeMillis());
Log.d(TAG,"filename: " + fileName);
File outFile = new File(dir, fileName);
Log.d(TAG,"outFile: " + outFile);
try {
outStream = new FileOutputStream(outFile);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outStream);
outStream.flush();
outStream.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
});
posterViewHolder.imageViewEdit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent i = new Intent();
i.setType("image/*");
i.setAction(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
// startActivityForResult(i, 0);
((Activity) context).startActivityForResult(Intent.createChooser(i, "CHOOSING INTENT"), 0);
}
});
}
@Override
public int getItemCount() {
return posterArrayList.size();
}
public class PosterViewHolder extends RecyclerView.ViewHolder {
RelativeLayout relativeLayoutImage;
ImageView imageViewBg, imageViewEdit, imageViewDownload, imageViewShare;
CircleImageView imageViewProfie;
public PosterViewHolder(@NonNull View posterView) {
super(posterView);
relativeLayoutImage = posterView.findViewById(R.id.image_relative);
imageViewBg = posterView.findViewById(R.id.image_bg);
imageViewProfie = posterView.findViewById(R.id.image_profile_moving);
imageViewEdit = posterView.findViewById(R.id.edit_image);
imageViewDownload = posterView.findViewById(R.id.download_image);
imageViewShare = posterView.findViewById(R.id.share_image);
}
}
}
и я хочу использовать этот класс
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == 0) {
final Uri selectedUri = data.getData();
if (selectedUri != null) {
startCrop(selectedUri);
} else {
Toast.makeText(context, "Cannot retrieve selected Image", Toast.LENGTH_SHORT).show();
}
} else if (requestCode == UCrop.REQUEST_CROP) {
handleCropResult(data);
}
}
if (resultCode == UCrop.RESULT_ERROR) {
handleCropError(data);
}
}
Пожалуйста, помогите мне обработать этот метод в интерфейсе.
Спасибо.
** ОБНОВЛЕНИЕ: **
Вот мой код активности, чтобы лучше понять мой вопрос.
RequestQueue requestQueue;
private ArrayList<Poster> posterArrayList = new ArrayList<>();
private RecyclerView recyclerView;
private PosterAdapter posterAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sending_image);
requestQueue = Volley.newRequestQueue(this);
recyclerView = findViewById(R.id.recycler_poster);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false));
getAllPoster();
}
private void getAllPoster() {
HashMap<String, String> params = new HashMap<String, String>();
params.put("poster_id", "1");
Log.d(TAG + "pp", String.valueOf(params));
String Url = Constants.Base_URL + "poster/";
JsonObjectRequest request = new JsonObjectRequest(Url, new JSONObject(params),
response -> {
Log.d("responsePending", String.valueOf(response));
try {
String statusResponseObject = response.getString("status");
String msgObject = response.getString("msg");
if (statusResponseObject.equals("200")){
JSONArray jsonArray = response.getJSONArray("response");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject pendingFragResponse = jsonArray.getJSONObject(i);
String posterObject = pendingFragResponse.getString("poster");
String positionObject = pendingFragResponse.getString("position");
String sizeObject = pendingFragResponse.getString("size");
String txt_positionObject = pendingFragResponse.getString("txt_position");
String titleObject = pendingFragResponse.getString("title");
String descriptionObject = pendingFragResponse.getString("description");
//
posterArrayList.add(new Poster(posterObject, positionObject,
sizeObject, txt_positionObject,
titleObject, descriptionObject));
posterAdapter = new PosterAdapter( posterArrayList, SendingImageActivity.this);
recyclerView.setAdapter(posterAdapter);
// wp10ProgressBar.hideProgressBar();
// wp10ProgressBar.setVisibility(View.GONE);
}
posterAdapter.notifyDataSetChanged();
// wp10ProgressBar.hideProgressBar();
}else {
// wp10ProgressBar.hideProgressBar();
// wp10ProgressBar.setVisibility(View.GONE);
Toast.makeText(SendingImageActivity.this, msgObject, Toast.LENGTH_SHORT).show();
}
} catch (JSONException e) {
e.printStackTrace();
Toast.makeText(this, "Server didn't response, Try after some time", Toast.LENGTH_LONG).show();
}
}, error -> {
error.printStackTrace();
Log.d(TAG + "error", String.valueOf(error.getMessage()));
Toast.makeText(this, "Server didn't response, Try after some time", Toast.LENGTH_LONG).show();
});
requestQueue.add(request);
}
}
} catch (JSONException e) {
