Onclick in fragment, FATAL EXCEPTION. Shared preferences to a fragment

Basic info
I am using the Settings Activity and navigation menu : and i have button to display the data (which is the number) from the settings to a textview. It's a sms app
Problem
I have the textview in context_main (The first screen when you start the app) But i would really like to have the textview in my fragment and when i press the button "the onlick" will display the value from settings.
The Button is in the fragment. and when i click the button it works^^ for the context_main se below code.
public void displayData(View view){
SharedPreferences prefs =PreferenceManager.getDefaultSharedPreferences(this);
String restoredText = prefs.getString("example_text", "");
radertst.setText(restoredText);
}
But when i press a button to send a sms and i linked it with the textfield for where the number is but then i get this.

if you look at

String mymsgaoff = aoffTxt.getText().toString();
String theNumber = numTxt.getText().toString();
sendMsg(theNumber, mymsgaoff);
}
The numTxt is where i want the value to be loaded and it's in the first layout xml not context_main. So for some reason it wont be loaded there. Imgur image

If I'm understanding you correctly, R.id.raderanumtxt is in the MainActivity's layout file and not FirstFragment's.
That means that it won't be found in the onCreateView() method of FirstFragment the way you're accessing it. The view object there is the layout you just loaded:
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.first_layout, container, false);
nyanumtxt = (TextView)view.findViewById(R.id.raderanumtxt); // <- this assignment won't work
...
}
You're also inflating R.layout.first_layout twice, which is unnecessary.
To get access to a View in the Activity, you can do something like this:
View view = getActivity().findViewById(R.id.viewid);
EDIT:
Without seeing your layouts, I can't be sure, but try and replace:
nyanumtxt = (TextView)view.findViewById(R.id.raderanumtxt);
... with:
nyanumtxt = (TextView) getActivity().findViewById(R.id.raderanumtxt);
That way you're looking for R.id.raderanumtxt in the entire Activity layout. This will only work if the Activity is available and the layout has already been added, so to be safer I'd move this assignment to onViewCreated() instead of onCreateView().

Android Actionbar shows no items

I'm new to android and have this problem for while: No item appear on action bar, as you can see in the image below:
Here is my menu_main.xml:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context="com.myappshop.myapp.MainActivity">
<item
android:id="#+id/action_favorite"
android:icon="#drawable/share_icon"
android:title="#string/share"
app:showAsAction="always"/>
<item
android:id="#+id/action_settings"
android:orderInCategory="100"
android:title="#string/action_settings"
app:showAsAction="ifRoom" />
</menu>
And the MainActivity.java:
public class MainActivity extends AppCompatActivity {
private static final String TAG = MainActivity.class.getSimpleName();
EditText mEditTextWord;
EditText mEditTextDefinition;
DictionaryDatabase mDB;
ListView mListView;
#Override
protected void onCreate(Bundle savedInstanceState) {

You have to inflate your menu.xml before you can call its menu items. Add this before onOptionsItemSelected()
#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;
}
Sorry about that. I also noticed that you didn't declare your toolbar in your activitys' onCreate(). You would have to declare your toolbar before placing menu items on it. Add this to your activity's onCreate method.
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
Also, make sure you include your toolbar/appbar layout in your main layout for this activity.

why my splash screen is so long

I'm trying to implement a splash screen on my app. After the loading of the splash screen, I have two issues.
If the user is connected, an activity is started. If not, an other is started.
But, with my implementation, when the user is connected, the splash screen is very long (8 or 9 sec), but I don't know why.
That is my first class which check if the user is connected, and it load some shared preferences? So maybe it's that?
public class AnnaActivity extends AppCompatActivity {
public PrefManager pref;
private AllRequest req;
private static final String REQUEST_TAG = "MainActivity";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.pref = new PrefManager(getApplicationContext());
boolean isco = pref.getIsConnect();
if (isco) {
Log.e("SPLASH", "IsConnected");
Intent loginActivity = new Intent(this, NavigationDrawerActivity.class);
startActivity(loginActivity);
finish();
} else {
Log.e("SPLASH", "launch login activity");
Intent loginActivity = new Intent(this, MainActivity.class);
startActivity(loginActivity);
finish();
}
}
}
that is my splash drawable
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#color/colorPrimaryDark"/>
<item android:bottom="8dp"
android:top="8dp"
android:left="8dp"
android:right="8dp">
<bitmap android:gravity="center"

How to save image from one activity to another

So i start on one screen that is for building an image. my build mode
When i click on stencil i go into a new activity that looks like this stencil picker
While in my stencil picker i have an onclick method for the pictures using a switch case. what i need to do is remember what image i clicked on and apply that image to the previous page. I need to also be able to save the images that are added to the build mode so they can stack ontop of each other (but that is a secondary problem).
here is my code for the build page
public class BuildMode extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener, AdapterView.OnItemSelectedListener {
private Button mStencilButton;
//private Button mColorButton;
private Button mUndoButton;
private Button mRedoButton;
private Spinner mColorSpinner;
private ImageView mImageView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_build_mode);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
//bit map to get stencil selected and place into build mode
// Bundle extras = getIntent().getExtras();
// byte[] byteArray = extras.getByteArray("picture");
// Bitmap bmp = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);
// ImageView image = (ImageView) findViewById(R.id.egg_image);
// image.setImageBitmap(bmp);
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);

and my code for the stencil page

public void useStencil(View view) {
// Intent intent = new Intent(this, BuildMode.class);
switch (view.getId()) {
case R.id.stencil_image_1:
// intent.putExtra("picture", byteArray);
// startActivity(intent);
break;

break;
case R.id.stencil_image_13:
break;
case R.id.stencil_image_14:
break;
}
}
private void imageClicked()
{
}
}

I would try this:
When you click on the stencil option, you need a way to know the position clicked by the user
Perhaps, you can easily create a variable to set when a stencil is clicked then pass that as an Extra to your previous activity
Once you are in the other activity, keep a simple integer array of your image drawables.
Finally, get the corresponding image from using the index you received through the intent. That should work!
I hope this helps!

ToolBar's Menu item is not clickable

I am having cart icon on ToolBar.When I try to click,it didn't show any action for a long time.After keep on clicking it, Toast message that I set is enabled or the app is crashed.
Please help me to fix it.
My Code is:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
badgeLayout = (RelativeLayout) menu.findItem(R.id.badge).getActionView();
mCounter = (TextView) badgeLayout.findViewById(R.id.counter);
badgeLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(context, "Cart is Working", Toast.LENGTH_SHORT).show();
Intent next = new Intent(context, ProductActivity.class);
startActivity(next);
}
});
return true;
}

The issue may already be closed, but I found possible cause:
if you used Relative Layout in your .xml file, neighboring elements can cover your toolbar.
So, your toolbar must be in top of views in your .xml file.
It's working for me.

You should go with OnOptionsItemSelected()
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case R.id.badge:
Toast.makeText(context, "Cart is Working", Toast.LENGTH_SHORT).show();
Intent next = new Intent(context, ProductActivity.class);
startActivity(next);
return true;
default:
return super.onOptionsItemSelected(item);
}
}
For more information check this link: http://developer.android.com/guide/topics/ui/menus.html

May be the problem is you are not calling super.onOptionsItemSelected(item) when badge is clicked. Change your method as follows :-
#Override
public boolean onOptionsItemSelected(MenuItem item) {
super.onOptionsItemSelected(item)
switch (item.getItemId()) {
case R.id.action_search:
break;
case R.id.badge:
Toast.makeText(context, "Cart is Working", Toast.LENGTH_SHORT).show();
/* Intent next = new Intent(context, ProductActivity.class);
startActivity(next);*/
break;
default:
break;
}
return true;
}
