Android app takes only a part of screen - java

My app for some reason takes just a part of screen.
Simple onCreate method:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_main);
}
Slightly more complicated layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/content_layout" >
<LinearLayout
android:id="#+id/mainLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin" >
<LinearLayout
android:id="#+id/func_layout"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="2"
android:background="#drawable/border_right"
android:orientation="vertical"
android:paddingLeft="#dimen/function_layout_padding"
android:paddingRight="#dimen/function_layout_padding" >
</LinearLayout>
<RelativeLayout
android:id="#+id/graph_layout"
android:layout_width="0dp"
android:layout_height="match_parent"
android:background="#FFF"
android:alpha="1.0"
android:layout_weight="5">
</RelativeLayout>
</LinearLayout>
</RelativeLayout>
And I got this:
I can't see what the trouble is. Thought that there is emulator problem but on real devices it looks the same.

Okay so try this :
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
You do not need that below because it will create this kind of windows.
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);

Thanks to #SunitKumarGupta #AnkitBansal and #Maxouille.
The problem was in Theme.
What it was:
<style name="Theme.Transparent" parent="AppBaseTheme">
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowBackground">#android:color/transparent</item>
<item name="android:windowContentOverlay">#null</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowIsFloating">false</item>
<item name="android:backgroundDimEnabled">false</item>
Problem item here is windowIsFloating. Removing it solved the issue.

What am I missing? Also why would it show up in the preview in android studio and not show when the app runs? Anyhelp is greatly appreciated
Yor forgot add setContentView(R.layout.activity_main); in your MainActivity
public class MainActivity extends AppCompatActivity {
public static final String EXTRA_MESSAGE = "com.example.myfirstapp.MESSAGE";

I want the navigation view to be only visible when the hamburger icon in the toolbar is clicked. Every tutorial I followed did the same things with me, however mine doesn't show inside the toolbar.
Pass toolbar instance during initiation of ActionBarDrawerToggle
actionBarDrawerToggle = new ActionBarDrawerToggle(this,drawerLayout, toolbar, R.string.open,R.string.close);

getSupportActionBar().setDisplayHomeAsUpEnabled(true); throws NullPointerException

First of all, I know this question has been asked before, I've spent an hour looking through other solutions, mostly from - getActionBar() returns null , and none have worked so another pair of eyes might be able to do something.
NavigationDrawer class which other classes inherit from:
public class NavigationDrawer extends AppCompatActivity {
String[] mDrawerTitles;
DrawerLayout mDrawerLayout;
ListView mDrawerList;
ActionBarDrawerToggle mDrawerToggle;
String activityTitle;
#Override
protected void onCreate(Bundle savedInstanceState) {
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
super.onCreate(savedInstanceState);
setContentView(R.layout.navigation_drawer_layout);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
mDrawerTitles = getResources().getStringArray(R.array.drawer_array);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.left_drawer);
activityTitle = getTitle().toString();
getSupportActionBar().setDisplayHomeAsUpEnabled(true); //here is where the error is thrown
getSupportActionBar().setHomeButtonEnabled(true);
addDrawerItems();
navDrawerSetup();
}

In NavigationDrawer activity you are performing setContentView(R.layout.navigation_drawer_layout), and in navigation_drawer_layout there is no any Toolbar, which leads to an exception.
Doing the following in you NavigationDrawer.class
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); //This is null
setSupportActionBar(toolbar);
You are setting Activity toolbar to null, because there is no view in your R.layout.activity_main with R.id.toolbar ID. So when you try to set toolbar after the code above, you are trying to set a property in a null object, that produces a null pointer exception.
Remove the two lines above in your activity or declare a Toolbar view with R.id.toolbar ID on your R.layout.activity_main layout file. Doing that you will solve the problem.

Not getting Custom Toolbar Title

I tried various solution to get toolbar title but none of them worked. like using and others. What went wrong with my code. can you advice. I m getting menu and their options but Title of toolbar no luck.
getSupportActionBar().setDisplayShowTitleEnabled(true);
getSupportActionBar().setTitle("Hello");

You can set title to toolbar for reference no need to get toolbar of support.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.setTitle("Hello");
setSupportActionBar(toolbar);
