Pass data from activity with retrofit

i'm create recycler view to display data, after that I want to pass
position of the data to the another activity, but when I use the loge for check if position is pass or not I can't found the position in logcat.
In MainActivity I add static list for Recipe model and I create method to return this list:
public class MainActivity extends AppCompatActivity {
private RecyclerView recyclerView;
private ProgressBar progressBar;
private LinearLayoutManager mLayoutManager;
private ArrayList<Model> list;
private RecyclerViewAdapter adapter;
private static List<Recipe>mListrecipe;
String url = "https://d17h27t6h515a5.cloudfront.net/";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
progressBar = (ProgressBar) findViewById(R.id.progressbar);
mLayoutManager = new LinearLayoutManager(MainActivity.this, LinearLayoutManager.VERTICAL, false);
recyclerView.setLayoutManager(mLayoutManager);
/// create a list--
list = new ArrayList<>();
/// get the list from json file
getRetrofitArray();
adapter = new RecyclerViewAdapter( list, MainActivity.this);
// set adapter to recyclerview
recyclerView.setAdapter(adapter);
}
public void getRetrofitArray(){
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(url)
.addConverterFactory(GsonConverterFactory.create())
.build();
RetrofitArrayAPI service = retrofit.create(RetrofitArrayAPI.class);
Call<List<Recipe>> call = service.getRecipeDetails();
call.enqueue(new Callback<List<Recipe>>() {
#Override
public void onResponse(Call<List<Recipe>> call, Response<List<Recipe>> response) {
Log.e("main ", " retrofit response "+ response.body().toString());
mListrecipe=response.body();
for (int i=0; i<response.body().size();i++){
Log.e("main ", " name "+ response.body().get(i).getName() + " serving "+
response.body().get(i).getServings());
list.add( new Model( Model.IMAGE_TYPE,response.body(), response.body().get(i).getName() ,
" Serving " +response.body().get(i).getServings() ) );
}
adapter.notifyDataSetChanged();
}
#Override
public void onFailure(Call<List<Recipe>> call, Throwable t) {
Log.e("main ", " retrofit error "+ t.toString());
}
});
}
public static List<Recipe>getList(){
return mListrecipe;
}
}
I add putExtra with key value to pass position
public class RecyclerViewAdapter extends RecyclerView.Adapter {
private ArrayList<Model> dataset;
private Context mContext;
public RecyclerViewAdapter(ArrayList<Model> mlist, Context context) {
this.dataset = mlist;
this.mContext = context;
}
public static class ImageTypeViewHolder extends RecyclerView.ViewHolder{
ImageView imageView;
TextView title, subtitle;
public ImageTypeViewHolder(View itemView) {
super(itemView);
this.title = (TextView) itemView.findViewById(R.id.title);
this.subtitle = (TextView) itemView.findViewById(R.id.subtitle);
this.imageView=(ImageView)itemView.findViewById(R.id.imageview);
}
}
#Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from( parent.getContext()).inflate(R.layout.itemlist, parent, false);
return new ImageTypeViewHolder(view) ;
}
#Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, final int position) {
Model object = dataset.get(position);
( (ImageTypeViewHolder) holder).title.setText( object.title );
( (ImageTypeViewHolder) holder).subtitle.setText( object.subtitle );
/// dataset.get(position)
( (ImageTypeViewHolder) holder).title.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent=new Intent(mContext,SelectReceipe.class);
intent.putExtra("itempostion",position);
mContext.startActivity(intent);
}
});
( (ImageTypeViewHolder) holder).subtitle.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent=new Intent(mContext,SelectReceipe.class);
intent.putExtra("itempostion",position);
mContext.startActivity(intent);
}
});
( (ImageTypeViewHolder) holder).imageView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent=new Intent(mContext,SelectReceipe.class);
intent.putExtra("itempostion",position);
mContext.startActivity(intent);
}
});
}
#Override
public int getItemCount() {
return dataset.size() ;
}
}
this is 2 activity I pass position but i can't find value in logcat
public class SelectReceipe extends AppCompatActivity {
List<Recipe>sListRecipe;
public int itempostion;
private String TAG;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.selectreceipe);
sListRecipe=MainActivity.getList();
Intent i =getIntent();
itempostion= i.getExtras().getInt("itempostion");
Log.e(TAG,"itempostion"+String.valueOf(itempostion)+"valou"+sListRecipe.get(itempostion).getName().toString());
}

You are probably not getting the list because you are using the getter from a different Activity.Instead, you can pass your list via Intent, but for that, you should implement your class as Parcelable or Serializable .Here is a nice post for that How can I make my custom objects Parcelable? And one thing if you are bound to load and temporarily save a list so that you can use anywhere in App then you can use setter and getter in Android Application class.Here is a nice post for that Using the Android Application class to persist data

Sending a Notification by an AlarmManager

I want every minute to push a notifaction and a tried this:
https://stackoverflow.com/a/8801990
But the problem is, that the alarm doesn't run.
I tried to set Logs but I can't see them...
Now I've started a new project and here are my files, maybe one import is wrong, but I don't know...:
MainActivity.java
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//startService(new Intent(this, YourService.class));
Log.e("MainActivity", "onCreate");
}
}
Alarm.java
import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.PowerManager;
import android.util.Log;
import android.widget.Toast;
public class Alarm extends BroadcastReceiver{
#Override
public void onReceive(Context context, Intent intent)
{
PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "");
wl.acquire();
// Put here YOUR code.
Log.e("Alarm", "onReceive");
Toast.makeText(context, "Alarm !!!!!!!!!!", Toast.LENGTH_LONG).show(); // For example
wl.release();
}
public void setAlarm(Context context)
{
Log.e("Alarm", "setAlarm");
AlarmManager am =( AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
Intent i = new Intent(context, Alarm.class);
PendingIntent pi = PendingIntent.getBroadcast(context, 0, i, 0);
// Changed to 1 minute
am.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), 1000 * 60 * 1, pi); // Millisec * Second * Minute
}
public void cancelAlarm(Context context)
{
Intent intent = new Intent(context, Alarm.class);
PendingIntent sender = PendingIntent.getBroadcast(context, 0, intent, 0);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
alarmManager.cancel(sender);
}
}
YourService.java
import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.os.IBinder;
import android.util.Log;
public class YourService extends Service
{
Alarm alarm = new Alarm();
public void onCreate()
{
Log.e("Service", "onCreate");
super.onCreate();
}
#Override
public int onStartCommand(Intent intent, int flags, int startId)
{
Log.e("Service", "onStartCommand");
alarm.setAlarm(this);
return START_STICKY;
}
#Override
public void onStart(Intent intent, int startId)
{
alarm.setAlarm(this);
}
#Override
public IBinder onBind(Intent intent)
{
return null;
}
}
It's the same code like in the link, i just only changed the time to one minute...
Here is my Manifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<!--AutoStart Receiver -->
<receiver android:name="com.example.alarm.alarmmanagertest.AutoStart">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"></action>
</intent-filter>
</receiver>
<!-- Receiver and Permisson added -->
<receiver android:process=":remote" android:name="com.example.alarm.alarmmanagertest.Alarm"></receiver>
<uses-permission android:name="android.permission.WAKE_LOCK"></uses-permission>
<!-- Added my Service -->
<service
android:name=".YourService"
android:enabled="true"
android:process=":your_service" >
</service>
</application>
There is nothing in the Android Monitor like "E/Alarm: onReceive" and for example the toast also doesn't start.
To be honest I tried everything, also tried this here: http://it-ride.blogspot.de/2010/10/android-implementing-notification.html
Could someone help me please and is it the right way to push a notification?
Using API 16 now...

You can see, that there is something from the AlarmManager, but I think it's from an other App. Should I unstill my other Apps where I tried to work with the AlarmManager and restart my device?

Your <receiver> block in the manifest for the Alarm broadcast receiver is incorrect. The name attribute needs the FQN of the class or the shorthand ".Alarm", assuming that the class is part of the package declared at the top of the manifest file.

So guys I tried this one and it finally worked!

Some tips:
in <receiver android:name=""> write the whole name
don't forget the uses-permission
start a new project, insert this code and try to unterstand how it works
after that you can put in your project

Android Studio database

Hi everyone I am new in Java programming and in the android studio environment and I need your help.
I am building an application that demands storing records of appointments into a database. I have created navigation between the activity's and I have also create a class named DBhandler which is about create update and delete records so far so good but the moment I add the following part of code in the activity that is about to create a new row in the database:
DBHandler db = new DBHandler(this);
db.NewApointment(new Apointments(23123,text2,text3,text4,text5));
Intent sendIntent = new Intent(Create_Apointment.this, Records.class);
startActivity(sendIntent);
The application for some reason stops working. I did research for my problem but I did not found anything similar to my problem, could it be a bug of android studio or am I missing something? I will show you my whole code just make to easier to you
This is my main activity
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void CreateApo(View view)
{
Intent i = new Intent(MainActivity.this, Create_Apointment.class);
startActivity(i);
}
public void Edit_Apointment(View v)
{
Intent intent = new Intent(MainActivity.this, Records.class);
startActivity(intent);
}
}
This is the activity which is used to store a new appointment
public class Create_Apointment extends AppCompatActivity {
EditText editText=(EditText) findViewById(R.id.editText);
EditText editText2=(EditText) findViewById(R.id.editText2);
EditText editText3=(EditText) findViewById(R.id.editText3);
EditText editText4=(EditText) findViewById(R.id.editText4);
String text2= editText.getText().toString();
String text3= editText2.getText().toString();
String text4= editText3.getText().toString();
String text5= editText4.getText().toString();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_create__apointment);
}
public void back(View view)
{
Intent i = new Intent(Create_Apointment.this, MainActivity.class);
startActivity(i);
}
public void Create(View view)
{
DBHandler db = new DBHandler(this);
db.NewApointment(new Apointments(23123,text2,text3,text4,text5));
Intent sendIntent = new Intent(Create_Apointment.this, Katagrafes.class);
startActivity(sendIntent);
}
}
The following code is for the management of the database
public class DBHandler extends SQLiteOpenHelper {
private static final int DATABASE_VERSION=1;
//DATABASE NAME
private static final String DATABASE_NAME="APOINTMENTINFO";
private static final String APOINTMENT_TABLE="APOINTMENTS";
//Column NAMES
private static final String KEY_ID="id";
private static final String KEY_NAME="Name";
private static final String KEY_ADDRESS="Address";
private static final String KEY_PLACE="Place";
private static final String KEY_WRA="WRA";
public DBHandler(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
#Override
public void onCreate(SQLiteDatabase db)
{
String Create_APOINTMENTS_TABLE= "CREATE TABLE"+ APOINTMENT_TABLE + "(" + KEY_ID +"INTERGER PRIMARY KEY,"+ KEY_NAME + "TEXT," +KEY_ADDRESS + "TEXT," + KEY_PLACE+"TEXT,"+ KEY_WRA+"TEXT" + ")";
db.execSQL(Create_APOINTMENTS_TABLE);
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldversion, int newversion)
{
db.execSQL("DROP TABLE IF EXISTS " + APOINTMENT_TABLE );
onCreate(db);
}
//add-insert new apointment
public void NewApointment(Apointments apointments)
{
SQLiteDatabase db = this.getWritableDatabase();
ContentValues values= new ContentValues();
values.put(KEY_NAME, apointments.getName()); //ONOMA RADEVOY
values.put(KEY_ADDRESS, apointments.getAddress());// adress
values.put(KEY_PLACE, apointments.getPlace());//meros
values.put(KEY_WRA, apointments.getWraRad());//wra
db.insert(APOINTMENT_TABLE, null ,values);
db.close();
}

}
Also I have create a class named "appointments" to refer an appointment as an object in my application.
public class Apointments {
private int id;
private String Name;
private String Address;
private String Place;
private String WraRad;
public Apointments(int id, String Name, String Address, String Place, String WraRad )
{

this.Place=Place;
this.WraRad=WraRad;
}
public void setId(int id) {
this.id = id;
}
public void setName(String Name) {
this.Name=Name;
}
public void setAddress(String Address) {
this.Address=Address;
}
public void setPlace(String Place) {
this.Place=Place;
}
public void setWraRad(String WraRad) {
this.WraRad=WraRad;
}
public int getId()

How to check if checkbox was checked?

I am creating a quiz app for androids. I have 3 fragments and 3 checkboxes on first two of them. On the last fragment there is a button which when pressed opens an activity called "End". I need that on the "End" activity a result would appear of how many correct answers one have chosen.
Firstly, I've tried to check if it's working with only the first fragment, but I got stuck. The app closes when I press the button.
End.java:
package bandymas.viewpagerexample;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.TextView;
public class End extends ActionBarActivity {
private CheckBox checkBox1, checkBox2, checkBox3;
private Button button;
TextView newresult = (TextView)findViewById(R.id.textView1);
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_end);
getSupportActionBar().hide();
addListenerOnButton();
}
private void addListenerOnButton() {
checkBox1 = (CheckBox) findViewById(R.id.checkBox1);
checkBox2 = (CheckBox) findViewById(R.id.checkBox2);
checkBox3 = (CheckBox) findViewById(R.id.checkBox3);
button = (Button) findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
//Run when button is clicked
#Override
public void onClick(View v) {
StringBuffer result = new StringBuffer();
result.append("CheckBox1 : ").append(checkBox1.isChecked());
result.append("\nCheckbox2 : ").append(checkBox2.isChecked());
result.append("\nCheckBox3 :").append(checkBox3.isChecked());
newresult.setText("My Awesome Text");
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_naujas_baigimas, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}

Android App crashes when Initializing Bluetooth Adapter

I'm developing an Android app but as I am a newbie so can't figure out the solution to the problem. My application crashes when I install it on my Phone (Android 4.3) while it runs fine on the emulator. Though, I know that it crashes when I initialize my Bluetooth Adapter mBluetoothAdapter, but dont know the solution.
public class MainActivity extends ActionBarActivity {
protected static final int REQUEST_ENABLE_BT = 1;
Button btnConnect;
int seekVal;
SeekBar seek ;
TextView editText1;
BluetoothAdapter mBluetoothAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btnConnect = (Button)findViewById(R.id.btnConnect);
editText1 = (TextView)findViewById(R.id.editText1);
seekVal = 0;
seek = (SeekBar)findViewById(R.id.seekBar1);
editText1.setText(String.valueOf(0));
// Crashes when Bluetooth Adapter is initialized
mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
// App runs when the above line is commented out
try{
if (mBluetoothAdapter == null) {
Toast.makeText(getApplicationContext(), "Your device does not support bluetooth device. Sorry but the application will exit now!", Toast.LENGTH_SHORT).show();
btnConnect.setEnabled(false);
}
else
{
if (mBluetoothAdapter.isEnabled()) {
btnConnect.setEnabled(false);
}
}
}
catch(Exception ex)
{
}
btnConnect.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
}
}

Basically the problem was of insufficient user permission in the Manifest
https://stackoverflow.com/a/11469502/1584140 helped me to use try catch for getting the actual error.
Finally I solved my issue by setting up the permissions like this.
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.BLUETOOTH" />
