How to adjust space between Icon and Title in NavigationView?

How to adjust this ? I am trying to make a navigation drawer in my app,I managed to add horizontal lines between items, but I want to adjust space between the icon and the title.

The best approach is to use a RecyclerView inside NavigationDrawer. You can always customize a recyclerView item (i.e. providing gaps between different elements).

another way to implement this,,
use navigation bar like this
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="end"
app:headerLayout="#layout/drawer_header"
android:background="#00fdfdfd"
app:itemIconTint="#android:color/white"
app:itemTextColor="#android:color/white">
<LinearLayout
android:animateLayoutChanges="true"
android:layout_marginTop="45dp"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="#+id/pull_navBar"
android:layout_width="35dp"
android:layout_height="match_parent">
<ImageView
android:layout_marginTop="105dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_double_arrow_left"/>
</LinearLayout>
<LinearLayout
android:background="#color/grey"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:padding="2dp"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:weightSum="2">
<TextView
android:textColor="#android:color/holo_blue_light"
android:text="Date"
android:textSize="16dp"
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="wrap_content" />
<TextView
android:textColor="#android:color/holo_blue_light"
android:text="Session Name"
android:layout_weight="1"
android:textSize="16dp"
android:layout_width="0dp"
android:layout_height="wrap_content" />
</LinearLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/rec_sessionList"
android:layout_width="match_parent"
android:layout_height="fill_parent"/>
</LinearLayout>
</LinearLayout>
</android.support.design.widget.NavigationView>
you can put any root layout inside the navigation and achive any view

Add this code in style.xml
<style name="NavStyle" parent="Base.TextAppearance.AppCompat">
<item name="android:textSize">14sp</item>
<item name="android:textStyle">bold</item>
<item name="android:textColor">#color/candidate_title</item>
<item name="android:padding">0dip</item>
</style>
and set app:itemIconPadding="#dimen/activity_margin_10dp"
app:itemTextAppearance="#style/NavStyle"in NavigationView

How to remove padding i have set the style but its not working

Following the codes:
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.your_dialog_content);
dialog.getWindow().setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT);

can you try set layouts without style class in xml file?
<?xml version="1.0" encoding="utf-8"?>

Centering the Text in the Toolbar is against Android design standards. I think this is why you are having issues accomplishing this. I would not try to adjust your text alignment, which will insure your app fits within the Android ecosystem.
Check this link for details on Toolbar design standards: http://www.google.com/design/spec/layout/structure.html#structure-toolbars
I am not answering how you WOULD do what you are asking, but suggesting that you DON'T do it in the first place (use the standard format, and this will be easier for you).

try this code...
Toolbar's parent is viewgroup. So u cannot design like that. I used FrameLayout to place items.
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="#color/primary">
<ImageButton
android:id="#+id/show_list_actualites"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_launcher"
android:adjustViewBounds="true"
android:layout_toLeftOf="#+id/loupe"
android:layout_marginLeft="20dp"

How to change text color of a custom view list item for menu drawer when selected - DrawerLayout

I am a new android developer. In my app I have a drawer using DrawerLayout of android:
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout

<ListView
android:id="#+id/left_drawer"

android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:background="#drawable/menu"/>
</android.support.v4.widget.DrawerLayout>
and this is my custom layout for list items:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"

android:background="?android:attr/activatedBackgroundIndicator"
Anyone can help please?
