how to remove left margin of Android Toolbar?

Question

I'm trying to use toolbar for my project. Here is the code I am using:

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:layout_alignParentTop="true"
    android:background="?attr/colorPrimary"
    android:contentInsetLeft="0dp"
    android:elevation="@dimen/margin_padding_8dp"
    android:contentInsetStart="0dp">

    <RelativeLayout
        android:id="@+id/rlToolbar"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <TextView
            android:id="@+id/tvTitle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"
            android:paddingRight="@dimen/margin_padding_16dp"
            android:text="AppBar"
            android:textAppearance="@style/TextAppearance.AppCompat"
            android:textColor="@color/white"
            android:textSize="@dimen/text_size_20sp" />

    </RelativeLayout>

I want to remove left margin, Here I set android:contentInsetLeft="0dp" and android:contentInsetStart="0dp" but it's not working..Please help me !

Concatenate

change to use app:contentInsetLeft="0dp" and app:contentInsetStart="0dp". add xmlns:app="schemas.android.com/apk/res-auto" to most parent view xml – Univocal

@Univocal thanks for the answer .. works like a charm .. – Inchoate

This is not left margin, Its Toolbar inner side space so we call toolbar left padding and you can remove left padding. Remove Space – Pervasive

possible duplicates @Concatenate – Diao

Answer 1

replace your xml with below xml

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:layout_alignParentTop="true"
    android:background="?attr/colorPrimary"
    android:elevation="@dimen/margin_padding_8dp"
    android:contentInsetStart="0dp" 
    android:contentInsetLeft="0dp"
    android:contentInsetRight="0dp"
    android:contentInsetEnd="0dp"
    app:contentInsetLeft="0dp"
    app:contentInsetStart="0dp"
    app:contentInsetRight="0dp"
    app:contentInsetEnd="0dp">

<RelativeLayout
    android:id="@+id/rlToolbar"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:id="@+id/tvTitle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:paddingRight="@dimen/margin_padding_16dp"
        android:text="AppBar"
        android:textAppearance="@style/TextAppearance.AppCompat"
        android:textColor="@color/white"
        android:textSize="@dimen/text_size_20sp" />

</RelativeLayout>

With navigationIcon, add app:contentInsetStartWithNavigation="0dp" – Stav

Answer 2

Use app:contentInsetStart="0dp" to remove that left space.

Answer 3

See the below code and here I added app:contentInsetStart="0dp". You need to add that to your code because before API 21 (i.e. Lollipop) you need to add that line.

<android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="64dp"
            android:background="@color/colorPrimary"
            android:minHeight="?attr/actionBarSize"
            android:contentInsetStart="0dp"
            app:contentInsetStart="0dp"
            >
 </android.support.v7.widget.Toolbar>

Answer 6

This works for me...

<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app2="http://schemas.android.com/apk/res-auto"
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:background="@color/colorPrimary"
    app2:contentInsetStart="0dp"/>

Ivanivana

you have to emphasize the xmlns part on the toolbar, it seems when you auto add it, it adds to the top most parent, and that doesnt work – Sheave

Answer 7
