Im creating a RecyclerView using jdbc connection and mysql database. Inside the RecyclerView I am uploading data from my database into one TextView and three radioButtons . Everything works just fine, but my problem is that it only shows the first RadioButton and there is nothing in the second and third one.
Here is my java code :
public class GererVoteInvite extends AppCompatActivity {
private ArrayList<VoteItem> itemArrayList; //List items Array
private MyAppAdapter myAppAdapter; //Array Adapter
private RecyclerView recyclerView; //RecyclerView
private RecyclerView.LayoutManager mLayoutManager;
private boolean success = false; // boolean
private static final String DB_URL = "jdbc:mysql://10.0.2.2/mvoting_db_1.0.0.0";
// private static final String DB_URL = "jdbc:mysql://172.16.24.25/mvoting_db_1.0.0.0"; //"jdbc:mysql://DATABASE_IP/DATABASE_NAME";
private static final String USER = "mootaz";
private static final String PASS = "mootaz";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_gerer_vote_invite);
recyclerView = (RecyclerView) findViewById(R.id.recyclerView); //REcyclerview Declaration
recyclerView.setHasFixedSize(true);
// use a linear layout manager
mLayoutManager = new LinearLayoutManager(this);
recyclerView.setLayoutManager(mLayoutManager);
itemArrayList = new ArrayList<VoteItem>(); // Arraylist Initialization
// Calling Async Task
SyncData orderData = new SyncData();
orderData.execute("");
}
// Async Task has three overrided methods,
private class SyncData extends AsyncTask<String, String, String> {
String msg = "Internet/DB_Credentials/Windows_FireWall_TurnOn Error, See Android Monitor in the bottom For details!";
ProgressDialog progress;
//Starts the progress dailog
#Override
protected void onPreExecute() {
progress = ProgressDialog.show(GererVoteInvite.this, "Synchronising",
"RecyclerView Loading! Please Wait...", true);
}
// Connect to the database, write query and add items to array list
#Override
protected String doInBackground(String... strings) {
try {
Class.forName("com.mysql.jdbc.Driver");
Connection conn = DriverManager.getConnection(DB_URL, USER, PASS); //Connection Object
if (conn == null) {
success = false;
} else {
// Change below query according to your own database.
String query = "SELECT lib_probleme , lib_solution_1 , lib_solution_2 , lib_solution_3 FROM reunion JOIN probleme JOIN solution WHERE reunion.id_reunion=probleme.id_reunion and probleme.id_probleme=solution.id_probleme ;";
Statement stmt = conn.createStatement();
java.sql.ResultSet rs = stmt.executeQuery(query);
// if resultset not null, I add items to itemArraylist using class created
if (rs != null) {
while (rs.next()) {
try {
itemArrayList.add(new VoteItem(rs.getString("lib_probleme"), rs.getString("lib_solution_1"), rs.getString("lib_solution_2"), rs.getString("lib_solution_3")));
} catch (Exception ex) {

}
}

}
}
} catch (Exception e) {

Writer writer = new StringWriter();
e.printStackTrace(new PrintWriter(writer));
msg = writer.toString();
success = false;
}
return msg;
}
// disimissing progress dialoge, showing error and setting up my gridview
#Override
protected void onPostExecute(String msg) {
progress.dismiss();
Toast.makeText(GererVoteInvite.this, msg + "", Toast.LENGTH_LONG).show();
if (success == false) {
} else {
try {
myAppAdapter = new MyAppAdapter(itemArrayList, GererVoteInvite.this);
recyclerView.setAdapter(myAppAdapter);
} catch (Exception ex) {
}
}
}
}
public class MyAppAdapter extends RecyclerView.Adapter<MyAppAdapter.ViewHolder> {
private List<VoteItem> values;
public Context context;
public class ViewHolder extends RecyclerView.ViewHolder {
public TextView txtProbleme;
public RadioGroup group;
public RadioButton txtSol1;
public RadioButton txtSol2;
public RadioButton txtSol3;
public View layout;
public ViewHolder(View v) {
super(v);
layout = v;
group = (RadioGroup) v.findViewById(R.id.radio_group);
txtProbleme = (TextView) v.findViewById(R.id.tv_probleme);
txtSol1 = (RadioButton) v.findViewById(R.id.rb_1);
txtSol2 = (RadioButton) v.findViewById(R.id.rb_2);
txtSol3 = (RadioButton) v.findViewById(R.id.rb_3);
}
}
// Constructor
public MyAppAdapter(List<VoteItem> myDataset, Context context) {
values = myDataset;
this.context = context;
}
// Create new views (invoked by the layout manager) and inflates
#Override
public MyAppAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
// create a new view
LayoutInflater inflater = LayoutInflater.from(parent.getContext());
View v = inflater.inflate(R.layout.vote_view, parent, false);
ViewHolder vh = new ViewHolder(v);
return vh;
}
// Binding items to the view
#Override
public void onBindViewHolder(ViewHolder holder, final int position) {
final VoteItem voteItem = values.get(position);
holder.txtProbleme.setText(voteItem.getProbleme());
holder.group.setTag(position);
holder.txtSol1.setText(voteItem.getSol1());
holder.txtSol2.setText(voteItem.getSol2());
holder.txtSol3.setText(voteItem.getSol3());
}
// get item count returns the list item count
#Override
public int getItemCount() {
return values.size();
}
}
}
And here is my layout.xml that containt the item for the RecyclerView

I have a SQLite database and want to search Items thorugh DB and then showing the items on recyclerView. Everything looking fine but recyclerView not showing the pictures, But somehow It shows the Strings
Normally pictures I saved inside the SQLite as BLOB should be displayed on the left.
Here is SearchFragment (Where I make the search and start recyclerView to display items)
public class SearchFragment extends Fragment {
Button searchbutton;
EditText editText;
View v;
Cursor cursor;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
v = inflater.inflate(R.layout.fragment_search, container, false);
addListenerOnButton(v);
return v;
}
private void addListenerOnButton(View v) {
searchbutton = v.findViewById(R.id.searchfragment_button);
editText = v.findViewById(R.id.searchfragment_edittext);
searchbutton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String keystring = editText.getText().toString();
if(keystring.isEmpty())
Toast.makeText(getContext(),R.string.empty_search ,Toast.LENGTH_LONG).show();
else
new FoodQuery().execute(keystring);
}
});
}
//Place I start the search on background
private class FoodQuery extends AsyncTask<String, Void, Void>{
#Override
protected Void doInBackground(String [] keys) {
String name_col;
DietAppDatabaseHelper daDBHelper;
SQLiteDatabase daDB;
daDBHelper = new DietAppDatabaseHelper(getContext());
try {
daDB = daDBHelper.getReadableDatabase();
if (Locale.getDefault().getLanguage() == "tr")
name_col = "name_tr";
else
name_col = "name_eng";
String query = "SELECT * FROM food_data WHERE " //Query here
+ name_col + " LIKE ?" ;
cursor = daDB.rawQuery(query, new String[]{"%" + keys[0] + "%"});
viewResults(name_col);
daDB.close();
} catch (SQLiteException e){
Log.d("SearchFragment", "doInBackground: " + e);
}
return null;
}
}
private void viewResults(String lang) {
int name_col = -1; //For language issues not important
if(lang == "name_tr")
name_col = 1;
else if(lang == "name_eng")
name_col = 2;
ArrayList<String> tmpnames = new ArrayList<>(); //I put pictures to byte[] and names to String Arraylist here
ArrayList<byte[]> tmppictures = new ArrayList<>();
if(cursor.moveToFirst()){
tmpnames.add(cursor.getString(name_col));
tmppictures.add(cursor.getBlob(5));
while(cursor.moveToNext()){
tmpnames.add(cursor.getString(name_col));
tmppictures.add(cursor.getBlob(5));
}
}
else {
Looper.prepare();
Toast.makeText(getContext(), R.string.no_food_found, Toast.LENGTH_LONG).show(); //To prevent empty search
}
getActivity().runOnUiThread(new Runnable() {
#Override
public void run() {
RecyclerView recyclerView = v.findViewById(R.id.recycler_view);
SearchResultAdapter adapter = new SearchResultAdapter(getContext(), tmppictures, tmpnames);
recyclerView.setLayoutManager(new LinearLayoutManager(getContext(), LinearLayoutManager.VERTICAL, false));
recyclerView.setAdapter(adapter);
}
});
}
}

Here is the adapter
public class SearchResultAdapter extends RecyclerView.Adapter<SearchResultAdapter.ViewHolder>{
private ArrayList<byte[]> foodimages;
private ArrayList<String> foodnames;
private Context context;
public SearchResultAdapter(Context context, ArrayList<byte[]> foodimages, ArrayList<String> foodnames) {
this.foodimages = new ArrayList<>(foodimages);
this.foodnames = new ArrayList<>(foodnames);
this.context = context;
}
#NonNull
#Override
public ViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.search_result_item, parent, false);
ViewHolder holder = new ViewHolder(view);
return holder;
}
#Override
public void onBindViewHolder(#NonNull ViewHolder holder, int position) {
holder.foodname.setText(foodnames.get(position));
holder.foodimage.setImageBitmap(BitmapFactory.decodeByteArray(foodimages.get(position), 0, foodimages.size()));
}
#Override
public int getItemCount() {
return foodnames.size();
}
public class ViewHolder extends RecyclerView.ViewHolder{
ImageView foodimage;
TextView foodname;
RelativeLayout parentLayout;
public ViewHolder(#NonNull View itemView) {
super(itemView);
foodimage = itemView.findViewById(R.id.food_seacrh_image);
foodname = itemView.findViewById(R.id.food_search_name);
parentLayout = itemView.findViewById(R.id.search_item);
}
}
}
Lastly, the layout of my item to use in recyclerView
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="15dp"
android:id="#+id/search_item">
<ImageView
android:id="#+id/food_seacrh_image"
android:layout_width="100dp"
android:layout_height="100dp"
/>
<TextView
android:id="#+id/food_search_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/food_seacrh_image"
android:textColor="#FFFFFF"
android:layout_centerVertical="true"
android:layout_marginLeft="30dp"
android:textSize="17sp"
android:layout_toEndOf="#+id/food_seacrh_image"
android:layout_marginStart="30dp" />
It seems like the problem could be the line:
holder.foodimage.setImageBitmap(BitmapFactory.decodeByteArray(foodimages.get(position), 0, foodimages.size()));
Should probably be:
holder.foodimage.setImageBitmap(BitmapFactory.decodeByteArray(foodimages.get(position), 0, foodimages.get(position).size));
The third param on decodeByteArray should be the length (in bytes) of the image, you are passing in the actual number of images.
i've had a problem, when i've tried to view this below fragment showing "skipping layout". Can any one help me out how to solve this problem please.
I'm getting this "No adapter attached; skipping layout." when i CLICK any imageview on ThirdFragment UI ayout, not when the images display in Thirdfragment UI layout.

Try setting the setting the RecyclerView with an empty Adapter before you execute your AsyncTask.
View rootView= inflater.inflate(R.layout.fragment_third, container, false);
recyclerView = (RecyclerView) rootView.findViewById(R.id.recyclerView);
-->recyclerView.setAdapter(new RecyclerViewAdapter(getActivity(), new ArrayList<>(), null);
new JSONTask().execute(url, this);
Then create a method in the RecyclerViewAapter to load the the populated List<JsonURLFullModel> from the AsyncTask's onPostExecute.
public void loadJson(List<JsonURLFullModel> jsonList){
mValues = jsonList;
notifyDataSetChanged();
}
If that doesn't work trying loading on the Ui thread from Asynctask using runOnUiThread
runOnUiThread(new Runnable() {
#Override
public void run() {
adapter.loadJson(...)
}
});
Edit 1 Adding loadJson to your RecyclerViewAapter.class
#Override
public int getItemCount() {
return mValues.size();
}
public void loadJson(List<JsonURLFullModel> jsonList){
mValues = jsonList;
notifyDataSetChanged();
}
//Below interface implimentation can be found in ThirdFragment
// you can write below interface separetly or in you can write in this class like below
public interface ItemListener {
void onItemClick(int mPosition, List<JsonURLFullModel> mValues);
}
Call the method in your PostExecute
#Override
protected void onPostExecute(ThirdFragModel result) {
super.onPostExecute(result);
//jsonfull.setText(result);
//dialog.dismiss(); // closing dialog, before the content load in ListView(i.e until application lodading it will run, then dialog closes)
getActivity().runOnUiThread(new Runnable() {
#Override
public void run() {
adapter.loadJson(result.getMovieModelList());
}
});
}
Also add your the Layout manager for the RecyclerView in onCreateView
View rootView= inflater.inflate(R.layout.fragment_third, container, false);
recyclerView = (RecyclerView) rootView.findViewById(R.id.recyclerView);
-->recyclerView.setAdapter(new RecyclerViewAdapter(getActivity(), new ArrayList<>(), null);
layoutManager = new AutoFitGridLayoutManager(getActivity(), 500);
recyclerView.setLayoutManager(layoutManager);
I have an activity where items are coming from database , and i want set icons for the same. I tried listview but heard about recyclerview , but I cant seem to find the solution as to how can I load it. kindly help

initialize this in your activity;

You need to create custom RecylerView adapter
Step 1: gradle:
dependencies {
...
compile "com.android.support:recyclerview-v7:23.0.1"
}
Step 2: layout/activity_name.xml
<android.support.v7.widget.RecyclerView
android:id="#+id/my_recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical" />
Step 3: Create Custom Adapter
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
private ArrayList<String> mDataset;
// Provide a reference to the views for each data item
// Complex data items may need more than one view per item, and
// you provide access to all the views for a data item in a view holder
public class ViewHolder extends RecyclerView.ViewHolder {
// each data item is just a string in this case
public TextView txtHeader;
public TextView txtFooter;
public ViewHolder(View v) {
super(v);
txtHeader = (TextView) v.findViewById(R.id.firstLine);
txtFooter = (TextView) v.findViewById(R.id.secondLine);
}
}
public MyAdapter(ArrayList<String> myDataset) {
mDataset = myDataset;
}
// Create new views (invoked by the layout manager)
#Override
public MyAdapter.ViewHolder onCreateViewHolder(ViewGroup parent,
int viewType) {
// create a new view
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.rowlayout, parent, false);
// set the view's size, margins, paddings and layout parameters
ViewHolder vh = new ViewHolder(v);
return vh;
}
// Replace the contents of a view (invoked by the layout manager)
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
// - get element from your dataset at this position
// - replace the contents of the view with that element
final String name = mDataset.get(position);
holder.txtHeader.setText(mDataset.get(position));
holder.txtHeader.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
remove(name);
}
});
holder.txtFooter.setText("Footer: " + mDataset.get(position));
}
// Return the size of your dataset (invoked by the layout manager)
#Override
public int getItemCount() {
return mDataset.size();
}
}
Step 4: In your activity.java
setContentView(R.layout.my_activity);
mRecyclerView = (RecyclerView) findViewById(R.id.my_recycler_view);
// use this setting to improve performance if you know that changes
// in content do not change the layout size of the RecyclerView
mRecyclerView.setHasFixedSize(true);
// use a linear layout manager
mLayoutManager = new LinearLayoutManager(this);
mRecyclerView.setLayoutManager(mLayoutManager);
// specify an adapter (see also next example)
mAdapter = new MyAdapter(myDataset);
mRecyclerView.setAdapter(mAdapter);
Am developing a chat application.I have done them using smack library.Everything works fine,even the users also can chat with each other but am unable set the incoming messages to the right side of the ListView .

What i got so far is this
What am expecting is My Message(out going) to the right of the ListView And outgoing to the left of the screen.
Please Do suggest.
You can achieve this with using android:gravity and android:layout_gravity attributes in LinearLayout.
Please Refer Android Listview for chat application.
Use different layouts for textview inside list view. Every time the list view populates with a new entry (message), compare the current users Auth by the sender's Auth by using user.getEmail().
If they match, set layout gravity of aforementioned textview to right, else left.
I have a custom listView with three textViews. The data comes from a class with three ArrayLists, two of which are strings and the last one is an Integer. I have no problems populating and adding items to the list as I saw that when I displayed the ArrayList values on logCat via log.d, all three ArrayLists had their respectful items.
It seems to me that there is something wrong with the way I display data.
Here are the files:
list_row_layout.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:text="variant" />
<TextView
android:id="#+id/quantity"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:text="quantity" />
<TextView
android:id="#+id/unit"

android:layout_alignParentTop="true"
android:layout_marginRight="221dp"
android:layout_toLeftOf="#+id/quantity"
android:text="unit" />

Here is the part in my activity_order_form.xml that has the listView element.

When I execute a Log.d statement to display the contents of my ArrayLists, it shows that my quantityArray has elements [0, 1, 2, 3, 4, 5, 6, 7, 9].
I know I can just convert quantityArray to an ArrayList from an ArayList, but I don't want to do that.
I think there's something wrong with my CustomListAdapter.
Any thoughts?
There is no where that you actually set the view, as in, it doesn't do anything, if convertView is null, you can't call any methods of it, convertView, if its is not null, will be ViewHolder in your context, what you need to do is have an object which is extending some type of view, instantiate it, give it methods to set the values, things like that.
For example here is what I use in an adapter that displays simple messages:
public class MessageView extends RelativeLayout {
private TextView mBody;
private String mBodyString = "";
private boolean mDrawn = false;
private boolean mLocal = false;
public MessageView(Context context) {
super(context);
this.drawView();
}
public MessageView(Context context, String body) {
super(context);
mBodyString = body;
this.drawView();
}
public MessageView(Context context, String body, boolean local) {
super(context);
mBodyString = body;
mLocal = local;
this.drawView();
}
private void drawView() {
if (mDrawn)
return;
mDrawn = true;
this.removeAllViews();
LayoutInflater li = (LayoutInflater) this.getContext()
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.ALIGN_PARENT_TOP);
if(mLocal){
this.addView(li.inflate(R.layout.list_item_message_device, this, false),
params);
}else{
this.addView(li.inflate(R.layout.list_item_message_remote, this, false),
params);
}
mBody = (TextView) this.findViewById(R.id.tMessage);
mBody.setText(mBodyString);
}
public void setLocal(){
this.setLocal(true);
}
public void setLocal(boolean local){
mLocal = local;
mDrawn = false;
this.drawView();
}
public void setMessage(String body){
mBodyString = body;
mBody.setText(mBodyString);
}
}
I got it.
I changed
holder.quantityView.setText(String.valueOf(listData.get(position).getQuantityRow()));
to
holder.quantityView.setText(String.valueOf(listData.get(position).getQuantityArray().get(position)));
