Add toolbar in constraintLayout of a fragment layout

Question

I'm trying to add a toolbar inside a constraint layout but this is the result I'm getting:

As you can see it doesn't fit the whole screen. Here's my xml:

<android.support.constraint.ConstraintLayout 
    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"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        android:theme="@style/ThemeOverlay.AppCompat.ActionBar"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light">

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Fragment title"/>

    </android.support.v7.widget.Toolbar>
</android.support.constraint.ConstraintLayout>

The ConstraintLayout width and length are set to match parent (which should be the screen?) and the toolbar width is set to match the layout width. What am I missing?

toolbar autometically added in fragment if you are added custom view then create custom view file — Mitesh Vanaliya, Nov 17 '18 at 10:44
I think you've provided with the main_activity.xml .. please see the layout file and also post you fragment java file code — Ümañg ßürmån, Nov 17 '18 at 12:11

Try this out by adding these content inside toolbar

android:contentInsetLeft="0dp"
    android:contentInsetStart="0dp"
    app:contentInsetLeft="0dp"
    app:contentInsetStart="0dp"
    android:contentInsetRight="0dp"
    android:contentInsetEnd="0dp"
    app:contentInsetRight="0dp"
    app:contentInsetEnd="0dp"

I got this from Android: remove left margin from actionbar's custom layout. And u can try other solutions in there as well if this is not solve your problem.

try this you have to set the constraintTop to the parent and also make width value match constraints and set start and end constraint to parent,

check the code below

<android.support.constraint.ConstraintLayout
    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"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="0dp"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        android:theme="@style/ThemeOverlay.AppCompat.ActionBar"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light">

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Fragment title" />

    </android.support.v7.widget.Toolbar>
</android.support.constraint.ConstraintLayout>

so if use fragment check if the frame layout or fragment view doesn't have any padding or margin on your activity XML — Ahmed Wahdan, Nov 17 '18 at 11:02

I solved this issue by putting the action bar on the main activity instead of the fragment layout.
