Use onActivityResult in RecyclerViewAdapter

Use onActivityResult in RecyclerViewAdapter - java

I am trying to use onActivityResult in my RecyclerViewAdapter. But I get the error that the 'The method does not override from its superclass'. I tried implementing the interface but onActivityResult never gets called. I have already searched enough on the StackOverflow questions like this one but couldn't find anything helpful.

}
}
}
showImages.java
package com.example.waheed.telegramchat;
import android.content.Intent;
import android.os.Bundle;
import android.os.Environment;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.AdapterView;
import android.widget.GridView;
import com.ImageAdapter;
import java.io.File;
import java.util.ArrayList;
public class showImages extends AppCompatActivity {
ImageAdapter myImageAdapter;
GridView gridView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_show_images);
gridView = (GridView) findViewById(R.id.gridview);
myImageAdapter = new ImageAdapter(this);
gridView.setAdapter(myImageAdapter);
String ExternalStorageDirectoryPath = Environment
.getExternalStorageDirectory()
.getAbsolutePath();
String targetPath = ExternalStorageDirectoryPath + "/Android/data/org.telegram.messenger/cache/";
File targetDirector = new File(targetPath);
final ArrayList<String> imagePaths = new ArrayList<String>();
final File[] files = targetDirector.listFiles();
for (File file : files) {
if (file.getName().toLowerCase().endsWith(".jpg") ||
file.getName().toLowerCase().endsWith(".png")) {
imagePaths.add(file.getAbsolutePath());
myImageAdapter.add(file.getAbsolutePath());
}
}
gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String result = imagePaths.get(position);
Intent returnIntent = new Intent();
returnIntent.putExtra("result", result);
setResult(showImages.RESULT_OK, returnIntent);
finish();
}
});
}
}

The RecyclerView.ViewHolder class does not contain a definition of an onActivityResult method that it can override.
onActivityResult, as far as I understand, only appears as a method of the Activity & Fragment classes.
Move the code
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
Bitmap bitmap;
if (requestCode == 1) {
if (resultCode == showImages.RESULT_OK) {
String result = data.getStringExtra("result");
Toast.makeText(this.context, "Clicked item is " + result, Toast.LENGTH_SHORT).show();
bitmap = BitmapFactory.decodeFile(result);
RecyclerViewHolder.img_profile.setImageBitmap(bitmap);
}
if (resultCode == showImages.RESULT_CANCELED) {
//Write your code if there's no result
}
}
}
to the class that initiated the call to showImages. I noticed that showImages closes when item is clicked.
gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String result = imagePaths.get(position);
Intent returnIntent = new Intent();
returnIntent.putExtra("result", result);
setResult(showImages.RESULT_OK, returnIntent);
finish();
}
});

You have to override onActivityResult in your activity wich contains the recyclerview not in viewholder class

You must implement onActivityResult in your activity class not in RecyclerViewAdapter. This method is used from your activity to retrieve data from other intents/activities that have started from your activity and normally
it has no place inside RecyclerViewAdapter.

you should use onActivityForResult in activity ,and create interface to handle action ,logic - adapter only display view.

IndexOutOfBoundsException when making one Arraylist equal to another

I am trying to filter my RecyclerView using SearchView by following this guide: https://www.geeksforgeeks.org/searchview-in-android-with-recyclerview/
However, I am getting an IndexOutOfBoundsException when making one Arraylist equal to another, which I believe is happening at this portion of the code here:
public void filterList(ArrayList filteredlist) {

book_title = filteredlist;

How to change the rows color in Listview on specific data from Sqlite database

I have custom list view and my data is coming from sqlite database. Now I want to change specific listview item's background color according to the id. First, I check the id if exist in database, then change particular item row background color according to the id.
My problem is that it checks successfully, but when I tried to change background color it changes whole listview background color. Here is picture and code of my data. Then you'll get my point, what actually I want to say you!
My db:
Whole listview color change:

Assuming you store the IDs in private List<String>verseid;, you can use it to check the ID of current ListView item.
The current item position is passed to you in final int position parameter.
So to check and apply color:
Remove
if(CheckIsDataAlreadyInDBorNot("t_asv","id","1001001"))
{
holder.linearLayout.setBackgroundColor(Color.parseColor("#008577"));
}
from if (convertView == null) {
Then add this code right outside that if:
if("1001001".equals(verseid.get(position))) {
//change the color
} else {
//set the color to default
}
Note that due to the way the ListView works (recycling items) you have to set the default color inside else.

favorite Recycler view updates only on relaunching app

I developed a word app that contains English vocabularies and users can add their favorite word by clicking on a floating button. Every time my favorite list has at list one item it is updated but when it's empty it doesn't show anything but when I run app again list updates.
if you need any code let me know to send it .

In your FloatingActionButton onClick method after you save the new item in your database, insert your new item into your recyclerview datasource list and call notifyDatasetChanged() on the adapter.

Choice 1: in onResume() stub of MainActivity, call selectList() and selectFavorite() and then load the PageFragment again so that the new list is loaded properly.
This is the shortest wayout but this approach is very much unoptimized and is not recommended.
Choice 2: You will have to insert the new item in database as well as add it to the List and then call notifyDatasetChanged
In MainActivity within methods selectList() and selectFavorite() after you perform list.add(struct) and favourite.add(struct) respectively, you will have to call notifyDatasetChanged() for the Adapter.
But the problem is your RecyclerView is in the PageFragment whereas you're populating the list in MainActivity.
So move your selectList() and selectFavorite() to PageFragment where you first initialize the RecylerView then, set the Adapter and then populate the list and finally call notifyDatasetChanged() on your adapters.

Returning a class from StartActivityForResult in Android

I started a activity to grab contacts from a list of all the contacts on the phone. Now my issue is how do I return the selected checks correctly from the listview, directly into my Person class. Im not fully understanding the concept of Intents and Activities in general so please bear with me.
Here is how I start the Activity from MainActivity.java
static final int PICK_CONTACT_REQUEST = 1;
public void grabthecontacts(View view) {
Intent intent = new Intent(getApplicationContext(), SelectContactsActivity.class);
startActivityForResult(intent, 1);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1) {
if(resultCode == Activity.RESULT_OK){
String result=data.getStringExtra("result");
}
if (resultCode == Activity.RESULT_CANCELED) {
}
}
}
Here is the class it calls, Select Contacts Activity
package com.example.android.smsapp;
import android.content.Intent;
import android.database.Cursor;
import android.os.Bundle;
import android.app.Activity;
import android.provider.ContactsContract;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.ListView;
import android.widget.TextView;
import java.util.ArrayList;
import java.util.HashSet;
import java.util.Set;
public class SelectContactsActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_select_contacts);
populateListView();
Button SubmitButton = (Button) findViewById(R.id.submitbut);
SubmitButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
registerDoneClick(view);
}
});
}
ArrayList<Person> list = new ArrayList<>();
Set<Person> checkedlist = new HashSet<>();
public void populateListView() {
try {
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
while (phones.moveToNext()) {
String name = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
Person allcontacts = new Person(name, phoneNumber);
list.add(allcontacts);
}
phones.close();
}
catch (Exception e){
e.printStackTrace();
}
ListView listview2 = (ListView) findViewById(R.id.contactlistview);
ArrayAdapter<Person> adapter = new myListAdapter();
listview2.setAdapter(adapter);
listview2.setItemsCanFocus(false);
listview2.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
}
public class myListAdapter extends ArrayAdapter<Person> {
public myListAdapter() {
super(SelectContactsActivity.this, R.layout.da_item, list);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View itemView = convertView;
if (itemView == null) {
itemView = getLayoutInflater().inflate(R.layout.da_item, parent, false);
}
// Find person wot work with
Person currentperson = list.get(position);
// Fill the view
TextView nameboxview = (TextView) itemView.findViewById(R.id.NameView);
nameboxview.setText(currentperson.getName());
TextView numberboxview = (TextView) itemView.findViewById(R.id.NumberView);
numberboxview.setText(currentperson.getPhone());
CheckBox cb = (CheckBox)itemView.findViewById(R.id.checkBox);
cb.setTag(position);
if (cb.isChecked()) {
currentperson.setChecked(true);
}
return itemView;
}
}
public void registerDoneClick(View view) {
for (Person allcontacts : list) {
if(allcontacts.isChecked()) {
Person human = new Person(allcontacts.getName(), allcontacts.getPhone());
}
}
// How do I return human with this activity? or is there another method?
finish();
}
}
Im completely lost on how to return the values I want as a person, so I can simply do
hashsetname.add(human)
Any help even with general formatting is greatly appreciated, or any java tips too. Thank you

Try this,
First make Person class to Serializable,using
public class Person implements Serializable
now set ivalue in intent like this,
Intent returnIntent = new Intent();
returnIntent.putExtra("result", human);
setResult(Activity.RESULT_OK, returnIntent);
finish();
get value from intent in onActivityResult method,
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1) {
if(resultCode == Activity.RESULT_OK){
Person myObject = (Person) data.getParcelableExtra("result");
}
if (resultCode == Activity.RESULT_CANCELED) {
}
}
}

Intent i= new Intent();
i.putExtra("whatever",yourResult);
setResult(Activity.RESULT_OK, i);
finish();

add these two lines before calling finish();
Intent returnIntent = new Intent();
setResult(Activity.RESULT_OK, returnIntent);
finish();

Use onActivityResult in RecyclerViewAdapter - java

You have to override onActivityResult in your activity wich contains the recyclerview not in viewholder class

You must implement onActivityResult in your activity class not in RecyclerViewAdapter. This method is used from your activity to retrieve data from other intents/activities that have started from your activity and normally it has no place inside RecyclerViewAdapter.

you should use onActivityForResult in activity ,and create interface to handle action ,logic - adapter only display view.
