Get variables from one activity to another

I work simple android app for sending sms. I have 2 activities. One is main for sending 2 different messages with 2 different content but messages send to same number. On secund activity i have 3 fields: one is for input number to send messages, and other two are for message content. When I click save button app save user input and go back to main activity. And here start my problem. How can i send users input for number to send messages and messages content to main activity to send sms with saved user input? I am totally beginner with android developing so please help! Here is my MainActivity.java:
package com.example.davor.light;
import android.content.Intent; import
android.support.v7.app.ActionBarActivity; import android.os.Bundle;
import android.telephony.SmsManager; import
android.telephony.SmsMessage; import android.view.Menu; import
android.view.MenuItem; import android.view.View; import
android.widget.Button; import android.widget.ImageView; import
android.widget.TextView; import android.widget.Toast;
public class MainActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// GUMBI INFORMACIJE
Button ukljuci = (Button) findViewById(R.id.ukljuci);
Button iskljuci = (Button) findViewById(R.id.iskljuci);
Button postavke = (Button) findViewById(R.id.postavke);
final ImageView slika = (ImageView) findViewById(R.id.slika);
// INFORMACIJA O PORUCI
final String broj = "097";
final String ukljuciPoruka = "Uključi";
final String iskljuciPoruka = "Isključi";
// KLIK NA GUMB ISKLJUČI
iskljuci.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
try {
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(broj, null, iskljuciPoruka, null, null);
Toast.makeText(getApplicationContext(), "Isključeno! poslano na broj " + broj, Toast.LENGTH_LONG).show();
slika.setImageResource(R.drawable.off);
} catch (Exception e) {
Toast.makeText(getApplicationContext(),"Nemoguće isključiti!",Toast.LENGTH_LONG).show();
}
}
});
postavke.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent PostavkeActivity = new Intent(MainActivity.this,
Postavke.class);
startActivity(PostavkeActivity);
}
});
}
#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_main, 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);
} }
And here is code for my second activity from witch I want to pull users input to MainActivity:

}

}
private void gumbZaPovratak(){

You can use startActivityForResult()
You can refer this link:
http://hmkcode.com/android-startactivityforresult/

In Activity1
Intent myIntent = new Intent(this,Activity2.class);
myIntent.putExtra("var", variable_to_pass);
startActivity(myIntent);
In Activity2
Bundle extras = getIntent().getExtras();
if (extras != null) {
intentExtra = extras.getString("var"); // retrieving variable
}

You can add data to an intent like this :
String messageContent = (EditText) findViewById(yourMessageContentId).getText().toString();
String messageNumber = (EditText) findViewById(yourMessageNumberId).getText().toString();
intent.putExtra("com.example.davor.light.MESSAGE_CONTENT", messageContent);
intent.putExtra("com.example.davor.light.MESSAGE_NUMBER", messageNumber);
And then get it on the MainActivity :
Intent intent = getIntent();
String messageNumber = intent.getStringExtra("com.example.davor.light.MESSAGE_NUMBER");
String messageContent = intent.getStringExtra("com.example.davor.light.MESSAGE_CONTENT");

you can send information from one activity to other activity like bellow
Intent postavkeActivity = new Intent(MainActivity.this,
Postavke.class);
Bundle bundle=new Bundle();
bundle.putString(|"messageKey1", "message content1");
bundle.putString(|"messageKey2", "message content2");
postavkeActivity.putExtras(bundle);
startActivity(PostavkeActivity);
in main activity get bundle data like bellow
Bundle b=getIntent.getExtras();
String smsContent=b.getString("messageKey1");

I can't make a button appear (possibly issue with static referencing)

I want to make a button appear in the MenuActivity layout but the deciding if statement is in the CapitalReceiver class. I've tried adding 'static' to various variables but it didn't work. Please help!

//IDButton.setVisibility(View.VISIBLE);//
}
else if(capital == "NO"){
//status = "Status: Application Denied";//
}
}
}
}

Just glancing over your code, a possible solution (and perhaps not the best) would be to make the ID Button variable global. You would then instantiate it in the onCreate whilst still allowing it to be manipulated in other classes in this MenuActivity.
I hope this helps.

Intent not passing correct information

Im using intents to pass the noteId from my database to a different activity for displaying the information it was working and i went to work on another part of the project and now it seems to only pass one value and from playing about i have found that seems to be whatever is the next highest object on the ListView. Sorry if this is badly worded, Im not very good at explaining these things

Thanks in advance been searching around and debugging for hours with no luck.

Hi I think the problem is that you use the findViewById() method inappropriately in your onItemClick listener.
You should use:
tvNoteId = (TextView)view.findViewById(R.id.NoteId);
Notice that I call the findViewById method on the view given by the onItemClick method because you want to find the view with the id NoteId from the pressed item and not from the entire's activity content view.. the way you do it will search in the content view of your activity for the first id equal with NoteId ...

I think your note get deleted on the moment edit is clicked from the options menu.
At the end of case R.id.action_Editnote nothing is returned nor break is called so case R.id.action_Delnote will be executed as well. This is where you delete the note from your database.

In your switch, put a break:
switch (item.getItemId())
{
case R.id.action_Editnote:
tvNoteId = (TextView)findViewById(R.id.NoteId);
String NoteValue = tvNoteId.getText().toString();
Intent intent = new Intent(getApplication(),EditNote.class);
intent.putExtra("noteId", NoteValue);
startActivity(intent);
break;
case R.id.action_DelNote:
Intent intent1 = getIntent();
String NoteId = intent1.getStringExtra("noteId");
dbTools.deleteNote(NoteId);
Intent i = new Intent(getApplication(),MyNotes.class);
startActivity(i);
finish();
break;
}

Sensor Reading keeps increasing even after closing app, Android

I have make this app which calculates Linear Acceleration of device of all dimension, combines it, and calculates net acceleration. Top five acceleration values are stored in Shared Preference key-value pairs.
The problem is when I close the app and reopen it, I find the values increased to a much higher level. I don't seem to catch the point in the code from where it is happening.
Please Help me out.

Reusing Action Bar in all activities of application

I have created a MenuActivity which is having an Action Bar and an Split Action Bar. I want to use this actionbar and splitactionbar view for all activities in my application. I am a newbie to android so can somebody guide me stepwise about this.
Also I am trying to put the search icon on actionbar which is right now appearing on SplitActionBar. I have four icons on SplitActionBar and i want to show search icon on the actionbar not on the SplitActionBar. The search icon is a SearchView item which when clicked expands on ActionBar, which is very untidy. I want it to appear on rightmost position in the ActionBar and expand on the same when clicked.
This is MenuACtivity.java:

Create BaseActivity which implements action bar.
And all your activities must inherit BaseActivity (not Activity)
public class BaseActiivity extends Activity{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// action bar implementation
}
}
public class MainActivity extends BaseAcivity{
//your code
}
