Android volley singleton and custom gridview adapter

Android volley singleton and custom gridview adapter - java

I am using a custom gridview adapter to show images with volley singleton. But when I run it it returns the onErrorResponse. It looks like the adapter is not even set properly, is it something with where i set the adapter? I have tried setting it in onCreate but same error.
The adapter class looked fine so I think the problem is in MainActivity.
MainActivity.java:
public class MainActivity extends AppCompatActivity {
private final int THUMBNAIL_SIZE = 250;
private final String KEY = "IMAGE";
ArrayList<Bitmap> bitmaps = new ArrayList<Bitmap>();
private static final String URLS[] = {
"http://10.0.2.2/Android%20A4_1/germany.png",
"http://10.0.2.2/Android%20A4_1/indonesia.png",
"http://10.0.2.2/Android%20A4_1/japan.png",
"http://10.0.2.2/Android%20A4_1/sarawak.png",

"http://10.0.2.2/Android%20A4_1/switzerland.png",
};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
for(int i = 0; i<URLS.length; i++) {
LoadingImages(URLS[i]);
}
}
private void LoadingImages(String url) {
ImageLoader imageLoader = MySingleton.getInstance(getApplicationContext()).getImageLoader();
imageLoader.get(url, new ImageLoader.ImageListener() {
#Override
public void onResponse(ImageLoader.ImageContainer response, boolean isImmediate) {
Bitmap image = response.getBitmap();
Bitmap thumbnail = ThumbnailUtils.extractThumbnail(image, THUMBNAIL_SIZE, THUMBNAIL_SIZE);
bitmaps.add(thumbnail);
GridView gridView = (GridView)findViewById(R.id.grid_layout);
final ImageAdapter imageAdapter = new ImageAdapter(MainActivity.this, bitmaps);
gridView.setAdapter(imageAdapter);
gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
Intent intent = new Intent(getApplicationContext(), Main2Activity.class);

}
});
}

onClick for images in ViewPager

I've a image slider made with the help of ViewPager. I want to show different toast messages when clicked in different images loaded by ViewPager, how can i do that?
this my activity where image slider is shown:
public class MainActivity extends AppCompatActivity{
public static final String MAIN = "OTHER";
private static ViewPager mPager;
private static int currentPage = 0;
private static final Integer[] XMEN=
{R.drawable.benz2, R.drawable.benz2,
R.drawable.benz2};
private ArrayList<Integer> XMENArray = new ArrayList<Integer>();
#Override
protected void onCreate(...);
init();
}
private void init() {
for(int i=0;i<XMEN.length;i++)
XMENArray.add(XMEN[i]);
mPager = (ViewPager) findViewById(R.id.pager);
mPager.setAdapter(new com.example.nepali_test.MyAdapter(MainActivity.this,XMENArray));
CircleIndicator indicator = (CircleIndicator) findViewById(R.id.indicator);
indicator.setViewPager(mPager);
final Handler handler = new Handler();
final Runnable Update = new Runnable() {
public void run() {
if (currentPage == XMEN.length) {
currentPage = 0;
}
mPager.setCurrentItem(currentPage++, true);
}
};
Timer swipeTimer = new Timer();
swipeTimer.schedule(new TimerTask() {
#Override
public void run() {
handler.post(Update);
}
}, 3000, 3000);
}
and this is the adapter of the viewpager:
public class MyAdapter extends PagerAdapter {
private ArrayList<Integer> images;
private LayoutInflater inflater;
private Context context;
public MyAdapter(Context context, ArrayList<Integer> images) {
this.context = context;
this.images=images;
inflater = LayoutInflater.from(context);
}
#Override
public void destroyItem(ViewGroup container, int position, Object object) {
container.removeView((View) object);
}
#Override
public int getCount() {
return images.size();
}
#Override
public Object instantiateItem(ViewGroup view, int position) {
View myImageLayout = inflater.inflate(R.layout.slide, view, false);
ImageView myImage = (ImageView) myImageLayout
.findViewById(R.id.image);
myImage.setImageResource(images.get(position));
view.addView(myImageLayout, 0);
return myImageLayout;
}
#Override
public boolean isViewFromObject(View view, Object object) {
return view.equals(object);
}
}
I tried to make by adding
if (currentPage==1){
Toast.makeText(this, "page 1", Toast.LENGTH_SHORT).show();
}
in init() but it didn't work.

From what i could understand you need to display the toast when clicking on the image in each page of a ViewPager in which case an easy way is to add an onClickListener to your ImageView inside your adapter's instantiateItem method. So you should change/replace your method with this:
#NonNull
#Override
public Object instantiateItem(#NonNull final ViewGroup view, final int position) {
View myImageLayout = inflater.inflate(R.layout.slide, view, false);
ImageView myImage = (ImageView) myImageLayout
.findViewById(R.id.image);
myImage.setImageResource(images.get(position));
myImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(context.getApplicationContext(), "page "+position, Toast.LENGTH_SHORT).show();
}
});
view.addView(myImageLayout, 0);
return myImageLayout;
}

Try this:
#Override
public Object instantiateItem(View collection, final int pos) { //have to make final so we can see it inside of onClick()
LayoutInflater inflater = (LayoutInflater) collection.getContext()
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View page = inflater.inflate(R.layout.YOUR_PAGE, null);
page.setOnClickListener(new OnClickListener(){
public void onClick(View v){
//this will log the page number that was click
Log.i("TAG", "This page was clicked: " + pos);
}
});
((ViewPager) collection).addView(page, 0);
return page;
}
Hope this will work!

Make Image click interface in adapter class
public class MyAdapter extends PagerAdapter {
private ArrayList<Integer> images;
private LayoutInflater inflater;
private Context context;
MyClassImage myClassImage;
public interface MyClassImage{
void imageClick(String id);
}
public ViewPagerAdapter(Context context, ArrayList<Integer> images,MyClassImage myClassImage) {
this.context = context;
this.images=images;
this.myClassImage=myClassImage;
inflater = LayoutInflater.from(context);
}
#Override
public void destroyItem(ViewGroup container, int position, Object object) {
container.removeView((View) object);
}
#Override
public int getCount() {
return images.size();
}
#Override
public Object instantiateItem(ViewGroup view, int position) {
View myImageLayout = inflater.inflate(R.layout.z_slide_pager_item, view, false);
ImageView myImage = (ImageView) myImageLayout.findViewById(R.id.image);
myImage.setImageResource(images.get(position));
view.addView(myImageLayout, 0);
final int id=images.get(position);
final String imgId=String.valueOf(id);
myImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
myClassImage.imageClick(imgId);
}
});
return myImageLayout;
}
#Override
public boolean isViewFromObject(View view, Object object) {
return view.equals(object);
}
}
and implement it on your MainActivity class
public class MainActivity extends AppCompatActivity implements MyAdapter.MyClassImage {
public static final String MAIN = "OTHER";
private static ViewPager mPager;
private static int currentPage = 0;
private static final Integer[] XMEN= {R.drawable.benz2, R.drawable.benz2, R.drawable.benz2};
private ArrayList<Integer> XMENArray = new ArrayList<Integer>();
#Override
protected void onCreate(...);
init();
}
private void init() {
for(int i=0;i<XMEN.length;i++)
XMENArray.add(XMEN[i]);
mPager = (ViewPager) findViewById(R.id.pager);
mPager.setAdapter(new com.example.nepali_test.MyAdapter(MainActivity.this,XMENArray,this));
CircleIndicator indicator = (CircleIndicator) findViewById(R.id.indicator);
indicator.setViewPager(mPager);
final Handler handler = new Handler();
final Runnable Update = new Runnable() {
public void run() {
if (currentPage == XMEN.length) {
currentPage = 0;
}
mPager.setCurrentItem(currentPage++, true);
}
};
Timer swipeTimer = new Timer();
swipeTimer.schedule(new TimerTask() {
#Override
public void run() {
handler.post(Update);
}
}, 3000, 3000);
}
#Override
public void imageClick(String id) {
Toast.makeText(this, "page "+id, Toast.LENGTH_SHORT).show();
}
Hope it will be helpful to you.
Thanks.

How can I get a variable from RecyclerView Adapter passed to MainActivity?

I was just playing around with some code, learning new things, when I ran into this problem... I'm trying to pass a variable from my RecylcerViewAdapter to a method in MainActivity, but I just can't seem to accomplish it.
I tried a lot of different thing with interfaces and casting, but nothing did the trick. Since I'm fairly new to all of this, maybe I'm making a trivial mistake somewhere?
My Interface:
public interface AdapterCallback {
void onMethodCallback(int id);
}
This is my adapter class:
public class PostAdapter extends RecyclerView.Adapter<PostAdapter.ViewHolder> {
private List<Post> postList;
private Context context;
private AdapterCallback listener;
public PostAdapter() {
}
public PostAdapter(List<Post> postList, Context context) {
this.postList = postList;
this.context = context;
}
public void setListener(AdapterCallback listener) {
this.listener = listener;
}
#NonNull
#Override
public ViewHolder onCreateViewHolder(#NonNull ViewGroup viewGroup, int i) {
View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.recycler_layout, viewGroup, false);
return new ViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull final ViewHolder viewHolder, final int position) {
viewHolder.tvTitle.setText(postList.get(position).getTitle());
viewHolder.tvBody.setText(new StringBuilder(postList.get(position).getBody().substring(0, 20)).append("..."));
viewHolder.tvId.setText(String.valueOf(postList.get(position).getUserId()));
viewHolder.parentLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int id = postList.get(position).getId();
if (listener != null) {
listener.onMethodCallback(id);
}
}
});
}
#Override
public int getItemCount() {
return postList.size();
}
public class ViewHolder extends RecyclerView.ViewHolder {
TextView tvTitle;
TextView tvBody;
TextView tvId;
LinearLayout parentLayout;
public ViewHolder(View itemView) {
super(itemView);
tvTitle = itemView.findViewById(R.id.tvTitle);
tvBody = itemView.findViewById(R.id.tvBody);
tvId = itemView.findViewById(R.id.tvId);
parentLayout = itemView.findViewById(R.id.parentLayout);
}
}
}
And my MainActivity:
public class MainActivity extends AppCompatActivity {
public static final String TAG = "MainActivityLog";
private CompositeDisposable disposable = new CompositeDisposable();
#BindView(R.id.rvPosts)
RecyclerView rvPosts;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ButterKnife.bind(this);
rvPosts.setHasFixedSize(true);
rvPosts.setLayoutManager(new LinearLayoutManager(this));
populateList();
logItems();
}
private void populateList() {
MainViewModel viewModel = ViewModelProviders.of(MainActivity.this).get(MainViewModel.class);
viewModel.makeQuery().observe(MainActivity.this, new Observer<List<Post>>() {
#Override
public void onChanged(#Nullable List<Post> posts) {
PostAdapter adapter = new PostAdapter(posts, getApplicationContext());
rvPosts.setAdapter(adapter);
}
});
}
public void logItems() {
PostAdapter adapter = new PostAdapter();
adapter.setListener(new AdapterCallback() {
#Override
public void onMethodCallback(int id) {
MainViewModel viewModel = ViewModelProviders.of(MainActivity.this).get(MainViewModel.class);
viewModel.makeSingleQuery(id).observe(MainActivity.this, new Observer<Post>() {
#Override
public void onChanged(#Nullable final Post post) {
Log.d(TAG, "onChanged: data response");
Log.d(TAG, "onChanged: " + post);
}
});
}
});
}
#Override
protected void onDestroy() {
super.onDestroy();
disposable.clear();
}
}
The populateList() method works just fine, but the logItems() method is the problem.
So when i click on a view in RecyclerView I expect the log to output the title, description and ID of the post that was clicked. nut nothing happens...
So, any help would be appreciated.

Make adapter global variable i.e. a field. Use the same object to set every properties.
private PostAdapter adapter;
Replace your logItems method with this:
public void logItems() {
adapter.setListener(new AdapterCallback() {
#Override
public void onMethodCallback(int id) {
MainViewModel viewModel = ViewModelProviders.of(MainActivity.this).get(MainViewModel.class);
viewModel.makeSingleQuery(id).observe(MainActivity.this, new Observer<Post>() {
#Override
public void onChanged(#Nullable final Post post) {
Log.d(TAG, "onChanged: data response");
Log.d(TAG, "onChanged: " + post);
}
});
}
});
}
And populateList with this:
private void populateList() {
MainViewModel viewModel = ViewModelProviders.of(MainActivity.this).get(MainViewModel.class);
viewModel.makeQuery().observe(MainActivity.this, new Observer<List<Post>>() {
#Override
public void onChanged(#Nullable List<Post> posts) {
adapter = new PostAdapter(posts, getApplicationContext());
rvPosts.setAdapter(adapter);
logItems();
}
});
}
And don't call logItems() from onCreate

This is how I implement with my ListAdapters:
public class FeedbackListAdapter extends RecyclerView.Adapter<FeedbackListAdapter.ViewHolder> {
private final ArrayList<Feedback> feedbacks;
private View.OnClickListener onItemClickListener;
private View.OnLongClickListener onItemLongClickListener;
private final Context context;
public FeedbackListAdapter(ArrayList<Feedback> feedbacks, Context context) {
this.feedbacks = feedbacks;
this.context = context;
}
public void setItemClickListener(View.OnClickListener onItemClickListener) {
this.onItemClickListener = onItemClickListener;
}
public void setOnItemLongClickListener(View.OnLongClickListener onItemLongClickListener){
this.onItemLongClickListener = onItemLongClickListener;
}
public class ViewHolder extends RecyclerView.ViewHolder{
final TextView feedback, created, updated;
final LinearLayout mainLayout;
ViewHolder(View iv) {
super(iv);
/*
* Associate layout elements to Java declarations
* */
mainLayout = iv.findViewById(R.id.main_layout);
feedback = iv.findViewById(R.id.feedback);
created = iv.findViewById(R.id.created_string);
updated = iv.findViewById(R.id.updated_string);
}
}
#Override
public int getItemCount() {
return feedbacks.size();
}
#Override
#NonNull
public FeedbackListAdapter.ViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.fragment_feedback_table_row, parent, false);
return new FeedbackListAdapter.ViewHolder(view);
}
#Override
public void onBindViewHolder(final #NonNull FeedbackListAdapter.ViewHolder holder, final int position) {
/*
* Bind data to layout
* */
try{
Feedback feedback = feedbacks.get(position);
holder.feedback.setText(feedback.getContent());
holder.created.setText(feedback.getCreated());
holder.updated.setText(feedback.getUpdated());
holder.mainLayout.setOnClickListener(this.onItemClickListener);
holder.mainLayout.setOnLongClickListener(this.onItemLongClickListener);
holder.mainLayout.setTag(feedback.getDbID());
TypedValue outValue = new TypedValue();
context.getTheme().resolveAttribute(android.R.attr.selectableItemBackground, outValue, true);
holder.mainLayout.setBackgroundResource(outValue.resourceId);
}catch(IndexOutOfBoundsException e){
e.printStackTrace();
}
}
}

In onPopulateList you create an adaptor:
PostAdapter adapter = new PostAdapter(posts, getApplicationContext());
rvPosts.setAdapter(adapter);
However in public void logItems() { you used a different adapter
PostAdapter adapter = new PostAdapter();
adapter.setListener(new AdapterCallback() {
#Override
public void onMethodCallback(int id) {
...
}
});
Therefore the list is being populated with 1 adapter, but you are setting the listener on an unused second adapter.
The fix is to use the same adapter for both. If you make the adapater a field, and don't create a new one inside of logItems, but just set your listener it should work.
i.e.
// as a field in your class
private PostAdapter adapter;
then
// in `populateList()`
adapter = new PostAdapter(posts, getApplicationContext());
rvPosts.setAdapter(adapter);
and
// in `logItems()`
adapter.setListener(new AdapterCallback() {
#Override
public void onMethodCallback(int id) {
...
}
});

In Adapter
public class CustomerListAdapter extends RecyclerView.Adapter<CustomerListAdapter.OrderItemViewHolder> {
private Context mCtx;
ProgressDialog progressDialog;
//we are storing all the products in a list
private List<CustomerModel> customeritemList;
public CustomerListAdapter(Context mCtx, List<CustomerModel> orderitemList) {
this.mCtx = mCtx;
this.customeritemList = orderitemList;
progressDialog = new ProgressDialog(mCtx);
}

}
#Override

try {
//holder.textViewPINo.setText("PINo \n"+Integer.toString( order.getPINo()));

holder.c_contact.setText(customer.getMobile());
holder.i_name.setText(customer.getInteriorName());
holder.i_contact.setText(customer.getInteriorMobile());

} catch (Exception E) {
E.printStackTrace();
}
}
#Override

return customeritemList.size();

Android volley gridview onclick item index doesnt start with 0

I am using a custom gridview adapter to show images with volley singleton. The gridview showing the images are fine, its just that when I click the FIRST image it crashes instantly.
I have tried using URLS[i-6] but it doesnt return the right thing. There are 6 images, somehow the index of the first image is 6 thus causing the out of bound exception. I tried changing bits here and there that might cause the index starting at 6 but no result at all..
The error:
java.lang.ArrayIndexOutOfBoundsException: length=6; index=6
at com.example.user.assignmentfourtwo.MainActivity$1$1.onItemClick(MainActivity.java:80)
Which is this line:
Toast.makeText(MainActivity.this, URLS[i].toString(), Toast.LENGTH_LONG).show();

To load SD card images in grid view, please make few changes in loadImageSamples method of ModelOverviewFragmentController.java. Currently, the images are picked from snpe folder inside internal storage of the device and are populated on Grid View. To get all the images from the gallery, create AsyncTask class to load images from the Gallery to the Grid View with the help of Content Provider.
Please use this link https://stackoverflow.com/a/10877404 for code reference to load images on grid view.
Hope this helps!
Thank You

Search an data listview using edittext

I'm creating a Movie Catalog app using themoviedb API. How can I implement search using EditText?
I have a list view that contains the movie info.
App screenshot:
Now I want to use the EditText to find another movie, and the list view updated. How do I do that?

And your activity set EditText Listener to this..!
editText.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
#Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
#Override
public void afterTextChanged(Editable editable) {
adapter.getFilter().filter(charSequence.toString());
}
});
i hope it's helpful to you ..!

Implement addTextChangedListener() on your search EditText and as the text changes filter your list data and update MovieAdapter with filtered data.
