intent service not populating screen

intent service not populating screen - android

I have it set up so that when the user hits "clock in" it starts the intentservice, the intent service then updates the ui, the only problem is its not working.... here is my code for the main activity page :
package com.famousmods.payme;

public class PayTracker extends Activity {
private ResponseReceiver receiver;
private static double Reserve;
private static int Reserve1;
public static double money;
public static double counter;
private static int go;
private static int countdown;
public static int convert;
public static double HW;
public static double OTW;
public static double HPD;
#Override

// register reciver
IntentFilter filter = new IntentFilter(ResponseReceiver.ACTION_RESP);
filter.addCategory(Intent.CATEGORY_DEFAULT);
receiver = new ResponseReceiver();
registerReceiver(receiver, filter);
// Receive messages from options page
double pHW, pOTW, pHPD;
Intent intent = getIntent();
pHW = intent.getDoubleExtra(Options.MESSAGE_HW, 0);
pOTW = intent.getDoubleExtra(Options.MESSAGE_OTW, 0);
pHPD = intent.getDoubleExtra(Options.MESSAGE_HPD, 0);
if(pHW != 0){
HW = pHW;
OTW = pOTW;
HPD = pHPD;
}
// Color buttons
Button buttonc = (Button) findViewById(R.id.clockin);
buttonc.getBackground().setColorFilter(0xFF00FF00, PorterDuff.Mode.MULTIPLY);

final Button b = (Button) findViewById(R.id.clockout);
b.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_pay_tracker, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {

return true;
};
return super.onOptionsItemSelected(item);
}
public void sendMessage(View view) {
//Start IntentService
Intent msgIntent = new Intent(this, SimpleIntentService.class);
msgIntent.putExtra(SimpleIntentService.PARAM_IN_HW, HW);
msgIntent.putExtra(SimpleIntentService.PARAM_IN_OTW, OTW);
msgIntent.putExtra(SimpleIntentService.PARAM_IN_HPD, HPD);
startService(msgIntent);//}
}
public class ResponseReceiver extends BroadcastReceiver {
public static final String ACTION_RESP = "com.famousmods.payme.action.MESSAGE_PROCESSED";
#Override
public void onReceive(Context context, Intent intent) {
// Update UI, new "message" processed by SimpleIntentService
final TextView t1 = (TextView) findViewById(R.id.yourpay);
t1.setTextColor(Color.parseColor("#008000"));
final TextView t2 = (TextView) findViewById(R.id.payper);
String end = intent.getStringExtra(SimpleIntentService.PARAM_OUT_END);

t2.setText(result);
t1.setText(end);
}
}
#Override
public void onDestroy() {
this.unregisterReceiver(receiver);
super.onDestroy();
}
}
And Here is my intent service page, its set up so that swhen the intent starts it starts a timer that every 20ms should send the new intent back to the activity page, here is the code:

public static String end;
public static String result;
private static double Reserve;
private static int Reserve1;
public static double money;
public static double counter;
private static int go;
private static int countdown;
public static int convert;
public SimpleIntentService() {
super("SimpleIntentService");
}
#Override

// recieve from paytracker
double HW = intent.getDoubleExtra(PARAM_IN_HW, 1);

// Calculate pay per second

Accessing another activity's method

I have a medicine_activity class
package com.example.shubhmgajra.medikit;
import android.content.Intent;
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ListView;
import android.widget.Toast;
public class Medicine_Activity extends AppCompatActivity implements View.OnClickListener {
private static final String TAG = "Medicine_Activity";
private Button btnAdd;
private ListView listMeds;
private AppDatabase db;
private ArrayAdapter<MedicineRecord> arrayAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_medicine);
btnAdd = findViewById(R.id.btnAdd);
btnAdd.setOnClickListener(this);
listMeds = findViewById(R.id.listMeds);
listMeds.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
MedicineRecord medicineRecord = db.medicineRecordDao().findMedicineById(id + 1);
Intent intent = new Intent(getApplicationContext(), MedicineInputActivity.class);
startActivity(intent);
MedicineInputActivity.getInstance().update(medicineRecord, true);
}
});
db = AppDatabase.getInstance(getApplicationContext());
FeedAdapter feedAdapter = new FeedAdapter(Medicine_Activity.this, R.layout.list_record, db.medicineRecordDao().loadAllRecords());
listMeds.setAdapter(feedAdapter);
}
#Override
protected void onResume() {
super.onResume();
}
#Override
public void onClick(View v) {
Intent intent = new Intent(this, MedicineInputActivity.class);
startActivity(intent);
}
}
In this i am trying to call update() method of another activity namely MedicineInputActivity
package com.example.shubhmgajra.medikit;
import android.content.Intent;
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TimePicker;
import android.widget.Toast;
public class MedicineInputActivity extends AppCompatActivity implements View.OnClickListener {
private static final String TAG = "MedicineInputActivity";
static EditText dosage;
static EditText medName;
static TimePicker timePicker;
static Button btnSave;
Button btnInc;
Button btnDec;
private AppDatabase db;
private static MedicineInputActivity instance;
boolean isEdit;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_medicine_input);
isEdit = false;
instance = this;
dosage = findViewById(R.id.dosage);
dosage.setShowSoftInputOnFocus(false);
dosage.setCursorVisible(false);
medName = findViewById(R.id.medName);
timePicker = findViewById(R.id.simpleTimePicker);
btnInc = findViewById(R.id.btnInc);
btnDec = findViewById(R.id.btnDec);
btnInc.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String val = dosage.getText().toString();
int tempVal = Integer.parseInt(val);
tempVal++;
dosage.setText("" + tempVal);
}
});
btnDec.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String val = dosage.getText().toString();
int tempVal = Integer.parseInt(val);
if (tempVal > 0) {
tempVal--;
}
dosage.setText("" + tempVal);
}
});
btnSave = findViewById(R.id.btnSave);
btnSave.setOnClickListener(this);
db = AppDatabase.getInstance(getApplicationContext());
}
#Override
public void onClick(View v) {
String name = medName.getText().toString();
int min = timePicker.getMinute();
int hour = timePicker.getHour();
String val = dosage.getText().toString();
int dose = Integer.parseInt(val);
MedicineRecord medicineRecord = new MedicineRecord(name, dose, min, hour);
if (validate(name)) {
if (isEdit) {
db.medicineRecordDao().updateRecord(medicineRecord);
} else {
db.medicineRecordDao().insertRecord(medicineRecord);
}
Intent intent = new Intent(this, Medicine_Activity.class);
startActivity(intent);
} else {
Toast toast = Toast.makeText(getApplicationContext(), "Medicine name cannot be empty", Toast.LENGTH_SHORT);
toast.show();
}
}
private boolean validate(String name) {
if (name.length() == 0) {
return false;
} else {
return true;
}
}
public static MedicineInputActivity getInstance() {
return instance;
}
public void update(MedicineRecord medicineRecord, boolean isEdit) {
this.isEdit = isEdit;
dosage.setText(medicineRecord.getDosage());
medName.setText(medicineRecord.getMedName());
timePicker.setHour(medicineRecord.getHour());
timePicker.setMinute(medicineRecord.getMinute());
}
}
What i am trying to achieve is when the user taps the list item, the input activity is loaded and the user can update the record. I wasnt able to find an elegant solution other than making an update method in MedicineInputActivity and then getting an instance of MedicineInputActivity in Medicine_Activity and calling update.
I am getting errors like "Attempt to invoke virtual method 'void com.example.shubhmgajra.medikit.MedicineInputActivity.update() on a null object reference".

You can return data from second activity to the first activity when user is done updating the record. You should start second activity by calling startActivityForResult() instead of startActivity() in the first activity. You should also override onActivityResult() in the first activity. You can read more here.
UPDATE:
I think you want to send selected medicine details from Medicine_Activity to MedicineInputActivity. In that case, you can send selected medicine object by binding it to the intent as follows:
public class Medicine_Activity ... {
#Override
protected void onCreate(Bundle savedInstanceState) {
...
listMeds.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
MedicineRecord medicineRecord = db.medicineRecordDao().findMedicineById(id + 1);
Intent intent = new Intent(getApplicationContext(), MedicineInputActivity.class);
intent.putExtra("selectedMedicine", medicineRecord);
startActivity(intent);
MedicineInputActivity.getInstance().update(medicineRecord, true);
}
});
...
}
}
Then on MedicineInputActivity, you should be doing this:
public class MedicineInputActivity ... {
MedicineRecord selectedMedicineRecord;
#Override
protected void onCreate(Bundle savedInstanceState) {
...
selectedMedicineRecord = (MedicineRecord) getIntent().getParcelableExtra("selectedMedicine");
...
}
}
To be able to do this, your MedicineRecord class should implement Parcelable interface.

Activity doesnt mantain connection to its service after minimalising it

I have a problem with an activity after minimalising. Everything is going ok when i start an activity and press start button.

You aren't creating a connection to the service. You're only starting it, not binding it. So there's no connection to maintain.
It looks like you're trying to do quasi-binding via actions. Don't do that, properly bind the service and avoid a whole raft of problems like this.

Send a Obj Class from Service to Activity

i download this example from the net and i want modify to sent a Obj student from a service to activity already run.
This is the code, the communication from service to activity it's work fine, but the object arrived empty.

Many thanks!!!

May be the problem is you send from Service:
intent.putExtra("studente", student);
and want to receive in Activity:
Student student = (Student) getIntent().getParcelableExtra("student");
student - studentE
Make keys the same and try again, please
Hope it helps
UPD: The problem is in your Activity updateUI method:
private void updateUI(Intent intent) {
// String counter = intent.getStringExtra("studente");
Student student = (Student) getIntent().getParcelableExtra("student");
Log.d(TAG, "Ricevuto");
if (student != null) {
TextView txtCounter = (TextView) findViewById(R.id.txtCounter);
txtCounter.setText(student.mSAge);
} else {
Log.d(TAG, "Sudente Vuoto");
}
}
You use getIntent() but you should use intent provided in method params updateUI(Intent intent).
So, please, change this line:
Student student = getIntent().getParcelableExtra("student");
to
Student student = intent.getParcelableExtra("student");
and try again
