Can't change the color of toolbar

Question

Can anyone please, explain me, why my toolbar doesn't change its color even though I created another style like:

<style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">false</item>
</style>

added it in my manifest file like:

<activity
    android:name=".SettingsActivity"
    android:label="@string/title_activity_settings"
    android:parentActivityName=".MainActivity">
    <meta-data
        android:theme="@style/AppTheme.NoActionBar"
        android:name="android.support.PARENT_ACTIVITY"
        android:value="com.com.com.com.MainActivity" />
</activity>

and try to change the toolbar like:

Toolbar toolbar = new Toolbar(this);
toolbar.setBackgroundColor(getResources().getColor(R.color.light_blue));
setSupportActionBar(toolbar);

but still get

This Activity already has an action bar supplied by the window decor. Do not request Window.FEATURE_ACTION_BAR and set windowActionBar to false in your theme to use a Toolbar instead.

I even tried to getSupportActionBar().hide(); but still doesn't work.

XML :

<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:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin"
    tools:context="com.com.com.com.SettingsActivity"
    android:id="@+id/settings_activity">
</RelativeLayout>

Basically, what I want is to keep my global theme and just change toolbar color in one of the activities. That is why I don't create a toolbar inside xml file, I create it programmatically, add background color and want to set it.

This might help you.

here's styles.xml contains custom theme.

<resources>

<style name="AppBaseTheme" parent="Theme.AppCompat.Light"></style>

<style name="AppTheme" parent="AppBaseTheme"></style>

<style name="CustomTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">@color/primary</item>
    <item name="colorPrimaryDark">@color/primary_dark</item>
    <item name="colorAccent">@color/accent</item>
</style>

AndroidManifest.xml contains custom theme for SettingActivity

<activity
    android:name=".SettingActivity"
    android:label="@string/title_activity_setting"
    android:theme="@style/CustomTheme" >
</activity>

Layout file

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/settingRootLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.demo.SettingActivity" >

</RelativeLayout>

finally your Activity file

package com.example.demo;

import android.annotation.SuppressLint;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.ViewGroup;
import android.view.ViewGroup.LayoutParams;
import android.widget.RelativeLayout;

@SuppressLint("NewApi")
public class SettingActivity extends AppCompatActivity {

    private RelativeLayout rootLayout;
    private Toolbar mToolbar;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_setting);
        rootLayout = (RelativeLayout) findViewById(R.id.settingRootLayout);
        mToolbar = new Toolbar(this);
        mToolbar.setLayoutParams(
                new LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
        mToolbar.setBackgroundColor(getResources().getColor(R.color.light_blue));
        mToolbar.setFitsSystemWindows(true);
        rootLayout.addView(mToolbar);
        setSupportActionBar(mToolbar);
    }

}

Hope the below code helps you...

Create the theme in your styles.xml as follow:

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat">
    <item name="android:windowNoTitle">true</item>
    <item name="windowActionBar">false</item>
</style>

Make sure you have this in your gradle dependencies

compile "com.android.support:appcompat-v7:21.0.+"

In your layout xml files add this toolbar tag

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:minHeight="?attr/actionBarSize"
    android:background="#2196F3"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
</android.support.v7.widget.Toolbar>

In your manifest file add the theme you created to the acctivity

<activity
        android:name="com.javatechig.sample.MyActivity"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >

And finally, here is your activity

import android.support.v7.app.ActionBarActivity;
import android.support.v7.widget.Toolbar;

public class MyActivity extends AppCompatActivity{

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_my);

    // Set a toolbar to replace the action bar.
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
}
}

I think you're getting your toolbar in the wrong way. You're probably not extending Toolbar class. Try to get it directly by the id defined in the xml file.

Toolbar toolbar = (Toolbar) findViewById(R.id.myToolbar);

Then you can set it as support and eventually set your color.

Edit: Didn't see you're creating it programmatically. Try to set a simple AppTheme style like

<style name="NoToolbarStyle" parent="Theme.AppCompat.Light">
    <item name="android:windowActionBar">false</item>
    <item name="android:windowNoTitle">true</item>
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>

You need to take off android:theme="@style/AppTheme.NoActionBar" outside the meta-data tag :

  <activity
        android:name=".SettingsActivity"
        android:label="@string/title_activity_settings"
        android:theme="@style/AppTheme.NoActionBar"
        android:parentActivityName=".MainActivity">
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value="net.noorr.menote.menote.MainActivity" />
    </activity>

And in java code:

Toolbar toolbar = (Toolbar) findViewById(R.id.yourToolbarId);
toolbar.setBackgroundColor(getResources().getColor(R.color.light_blue));
setSupportActionBar(toolbar);
