I Have The Image Url's In a List now I want to Set those Url's to ImageView.
I'm new To Android Can Any One Help Me How To Solve This Problem.
Thankful To Them........
Best way to load images from server is
Glide.with(mContext)
.load(imageUrl)
.diskCacheStrategy(DiskCacheStrategy.ALL)
.placeholder(R.drawable.default)
.error(R.drawable.default)
.override(400, 400)
.centerCrop()
.into(imageView);
For more follow this :
https://github.com/bumptech/glide
Best way to achieve this is use picasso library.
Picasso.with(context)
.load(url)
.placeholder(R.drawable.user_placeholder)
.error(R.drawable.user_placeholder_error)
.into(imageView);
for more details
Try this,
URL photoUrl = new URL(imageUrl);
mIcon = BitmapFactory.decodeStream(photoUrl.openConnection() .getInputStream());
imageView.setImageBitmap(mIcon);

I am working on an Android Project to display Github repo details.
I am trying to first select org name for a particular company, like Amazon has orgs on Github like AWS, AMZN, AWSLABS etc.
For this I first create a List of clickable buttons via RecyclerView(which works).
Then when user clicks on a particular org_name, the App does a HTTP request to Github to fetch relevant info and display inside a fragment which uses another RecyclerView(not working RecyclerViewRepoAdapter.java).
This part does not work as onCreateViewHolder or onBindViewHolder is not called (getItemCount is called and returns correct length)
Tried some of the suggestions mentioned like in this link! but it didn't work.
Any help is appreciated!

You are attaching adapter after getting a response from the API
LinearLayoutManager layoutManager = new LinearLayoutManager(getContext());
listAdapter = new RecyclerViewRepoAdapter(getContext(), repositories); // List of Github repos to be display
recyclerView.setLayoutManager(layoutManager);
recyclerView.setAdapter(listAdapter); // Called from here after response from cloud funtion
Move this code in onCreateView
assert getArguments() != null;
View v = inflater.inflate(R.layout.fragment_github, container, false);
recyclerView = v.findViewById(R.id.repo_recycler_view);
LinearLayoutManager layoutManager = new LinearLayoutManager(getContext());
listAdapter = new RecyclerViewRepoAdapter(getContext(), repositories); // List of Github repos to be display
recyclerView.setLayoutManager(layoutManager);
recyclerView.setAdapter(listAdapter); // Called from here after response from cloud funtion
return v;
And after getting a response from Api in AsyncTask onPostExecute() Method add data into list and notify adapter
ParseResponse parseResponse = new ParseResponse(response);
repositories = parseResponse.getRepositories();
listAdapter.notifyDataSetChanged();
I have a custom ListView with a TextView that get data from mysql. What I want to get the content from textview when the item is clicked.
I have tried this,
mList.setOnItemClickListener(new AdapterView.OnItemClickListener() {

String value = mList.getItemAtPosition(position).toString();
Toast.makeText(getBaseContext(), value, Toast.LENGTH_LONG).show();

By using this code you can get the current value of the textview.
mList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
String contactId = ((TextView) view.findViewById(R.id.row_namap)).getText().toString();
Toast.makeText(getBaseContext(), value, Toast.LENGTH_LONG).show();
}
});
one mistake is there,
You already have arraylist in your activity so try this,
mList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
String value = array_list.get(position).getpenyakit_nama();
Toast.makeText(getBaseContext(), value, Toast.LENGTH_LONG).show();
}
});
Do let me know if this works or not
String value = mList.getItemAtPosition(position).toString();
it will be get Penyakit object.
if you want get penyakit_nama value, use below code.
String value = ((Penyakit)mList.getItemAtPosition(position)).getpenyakit_nama();
because generic type of your ArrayAdapter is <Penyakit>, getItemAtPosition() will return Penyakit object
I am new to android development. Here is a picture of my firebase database.
I am showing the name and an image of the movie in my android application in a custom list view.
Here is my ModelClass
public class ModelClass {
String name,imagelink;
public ModelClass() {
}
public ModelClass(String name, String imagelink) {
this.name = name;
this.imagelink = imagelink;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getImagelink() {
return imagelink;
}
public void setImagelink(String imagelink) {
this.imagelink = imagelink;
}
}
Here is my Adapter Class
import android.app.Activity;
import android.support.annotation.LayoutRes;
import android.support.annotation.NonNull;
import android.support.annotation.Nullable;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.TextView;
import com.bumptech.glide.Glide;
import com.google.firebase.database.DatabaseReference;
import com.google.firebase.database.FirebaseDatabase;
import java.util.List;
public class MyAdapter extends ArrayAdapter<ModelClass> {
private Activity context;
private int resource;
private List<ModelClass> listImage;
private DatabaseReference ref = FirebaseDatabase.getInstance().getReference().child("MovieDetails");
public MyAdapter(#NonNull Activity context, #LayoutRes int resource, #NonNull List<ModelClass> objects) {
super(context, resource, objects);
this.context = context;
this.resource = resource;
listImage = objects;
}
#NonNull
#Override
public View getView(int position, #Nullable View convertView, #NonNull ViewGroup parent) {
LayoutInflater inflater = context.getLayoutInflater();
View v = inflater.inflate(resource, null);
TextView tvName = (TextView) v.findViewById(R.id.movie_name_view);
ImageView img = (ImageView) v.findViewById(R.id.movie_image_view);
tvName.setText(listImage.get(position).getName());
Glide.with(context).load(listImage.get(position).getImagelink()).into(img);
return v;
}
public void addElement(ModelClass element) {
listImage.add(element);
}
}
And This is my Activity
import android.app.ProgressDialog;

progressDialog.show();
mDatabaseRef = FirebaseDatabase.getInstance().getReference("MovieDetails");
myAdapter = new MyAdapter(CheckMovieInfoActivity.this, R.layout.customlistview, imgList);
lv.setAdapter(myAdapter);
mDatabaseRef.addValueEventListener(new ValueEventListener() {

myAdapter.addElement(img);
}
myAdapter.notifyDataSetChanged();
}
#Override
public void onCancelled(DatabaseError databaseError) {
progressDialog.dismiss();
}
});
}
}
And this is my Custom List View XML

I want to add a delete button in the custom listview to delete the data and also the image from the database.
I am not getting any errors I just want to add a delete button to delete the data. Thanks in advance.
I did not add spinner on my layout
I did not use addView function
code
Spinner spinner = new Spinner(MainActivity.this);
ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_spinner_dropdown_item, myArray);
spinner.setAdapter(spinnerArrayAdapter);
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener()
{
public void onItemSelected(AdapterView<?> parent, View view, int pos, long id)
{
//this place is never called
}
public void onNothingSelected(AdapterView<?> parent)
{
}
});
I called spinner like this:
spinner.performClick();
After this I click one of my item which in my array and then I expect to fire onItemSelected but it never fires.
the problem is
onitemselected is never called.
thanks in advance
Try this,
1.Create a custom adapter.
2.set click Listener to textview in adapter.(so you can get position in adapter)
3.according to positon do whatever u feel like.
CustomModel.
public class CustomModel {
private String id;
private String description;
public char[] name;
public CustomModel() {
}
public CustomModel(String id, String description) {
this.id = id;
this.description = description;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return description;
}
public void setName(String description) {
this.description = description;
}
}

hope it may help you.
In order to programatically select item from spinner. you need to call
spinner.setSelection(1);
Whereas 1 in the index, you want to select

I can't find any errors or notice something irregular, so why is that happening?
you should extend BaseAdapter and implement abstract methods
#Override
public int getCount() {
return web.size();
}
#Override
public Object getItem(int position) {
return web.get(position);
}
#Override
public long getItemId(int position) {
return 0;
}
also you might change
txtTitle.setText((CharSequence) web.get(position));
to
txtTitle.setText((CharSequence) getItem(position));
now your adapter don't know size of web array
edit:
you can get one inflater in constructor and keep in class, no need to getting inflater each time (little bit better for perfomance)
LayoutInflater inflater = context.getLayoutInflater();
edit 2:
localhost put proper comment - you are removing all Views from RelativeLayout, also ListView, and creating new ListView without adding to Relative. keeping reference will not auto-add View
protected void onPostExecute(Object result) {
layout = (RelativeLayout) getView().findViewById(R.id.blogPage);
layout.removeView(getView().findViewById(R.id.txtLabel);
//assuming you need to remove only txtLabel
CustomList adapter = new CustomList(getActivity(), titles);
list.setAdapter(adapter);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Toast.makeText(getActivity(),
"You Clicked at " + titles.get(position),
Toast.LENGTH_SHORT).show();
}
});
}
