I have the following situation:
I have two activities (Main Activity and ProductCard Activity)
Main Activity has a RecyclerView with items in it.
( User can add items manually. For example he add 3 items)
User click on some item and go to the ProductCard Activity
In the ProductCard Activity user click on the button (moneyOk_readylist) and go to the Main Activity
But when User do last step, RecyclerView become blank (empty).
I know that it is connected with states, but doesn't understand how.
Can anyone help me?

but here i get an error to the line delegate1.setSupportActionBar(toolbar)
It can be two differents things :
You've imported android.widget.Toolbar instead of android.support.v7.widget.Toolbar
Your Activity has to extends AppCompatActivity if you want to use setSupportActionBar(toolbar)
If you extends AppCompatActivity you have to use Theme.AppCompat.Light.NoActionBar

#Skizo here everything works fine and extends Activity...
public class EnterDataActivity extends Activity implements AppCompatCallback {
private AppCompatDelegate delegate;
EditText editTextPersonName;
/**

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

//call the onCreate() of the AppCompatDelegate

//use the delegate to inflate the layout
delegate.setContentView(R.layout.enter_data);
editTextPersonName = (EditText) findViewById(R.id.et_person_name);
Toolbar toolbar= (Toolbar) findViewById(R.id.mytoolbar2);
delegate.setSupportActionBar(toolbar);

}

I did solved my issue , I had to include my toolbar layout in my activity layout... Thank you everyone for interest in solving my issue!!

Android App Keeps Crashing When Attempting to Start New Activity

Unfortunately I have been banging my head against the wall for quite some time trying to figure out why the app crashes every time I press the "Display" button. As you can see an intent is called when the button is pressed, which should subsequently "change" to the GraphicDisplay Activity. Any help is appreciated.

I think I see your problem. You call inside display ClickListener:
String colorSchemeVal = popupMenu.toString();
but you never initialize "popupMenu", unless you hit "colorScheme".

Two activities sending data to each other

Two activities are sending data to each other.
The first activity has a custom list view. The second has one text view and three buttons to increase and decrease a value.
When I click on the first activity, the second activity opens. The second activity increases the text view value and clicked the button. Data goes to the first activity. Same process again.
My problem is that the total value is not displayed in the first activity.
How can i show all increase and decrease values from the second activity in the first activity?

Collect the data from second activity and put into below intent .Then you will receive first activity.
Intent myIntent = new Intent(secondActivity.this, firstActivity.class);
myIntent.putExtra("COUNTSTRING", CountString); //add data

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
}
