How to change Toolbar home icon color

问题

I am using a android.support.v7.widget.Toolbar and learned from this post how to change the color of the hamburger icon to white, but the up/back arrow remains a dark color when I call

setDisplayHomeAsUpEnabled(true);

How can I make the arrow white as well?

Here is what my toolbar looks like when I call setDisplayHomeAsUpEnabled():

$\"enter$

...and here is the relevant portion of my styles.xml file:

<style name=\"AppTheme\" parent=\"Theme.AppCompat.NoActionBar\">
    <item name=\"colorPrimary\">@color/primary</item>
    <item name=\"colorPrimaryDark\">#194C5F</item>
    <item name=\"colorAccent\">@color/accent</item>
    <item name=\"drawerArrowStyle\">@style/WhiteDrawerIconStyle</item>
</style>

    <style name=\"WhiteDrawerIconStyle\" parent=\"Widget.AppCompat.DrawerArrowToggle\">
        <item name=\"spinBars\">true</item>
        <item name=\"color\">@android:color/white</item>
    </style>

I solved it by editing styles.xml:

<style name="ToolbarColoredBackArrow" parent="AppTheme">
    <item name="android:textColorSecondary">INSERT_COLOR_HERE</item>
</style>

...then referencing the style in the Toolbar definition in the activity:

<LinearLayout
    android:id="@+id/main_parent_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <android.support.v7.widget.Toolbar
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/toolbar"
        app:theme="@style/ToolbarColoredBackArrow"
        app:popupTheme="@style/AppTheme"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:minHeight="?attr/actionBarSize"
        android:background="?attr/colorPrimary"/>

Here is what you are looking for. But this also changes the color of radioButton etc. So you might want to use a theme for it.

<item name="colorControlNormal">@color/colorControlNormal</item>

回答3:

I solved it programmatically using this code:

final Drawable upArrow = getResources().getDrawable(R.drawable.abc_ic_ab_back_mtrl_am_alpha);
upArrow.setColorFilter(Color.parseColor("#FFFFFF"), PorterDuff.Mode.SRC_ATOP);
getSupportActionBar().setHomeAsUpIndicator(upArrow);

Revision 1:

Starting from API 23 (Marshmallow) the drawable resource abc_ic_ab_back_mtrl_am_alpha is changed to abc_ic_ab_back_material.

This answer maybe too late, but here is how I do it. Styling the toolbar will do the trick. Create toolbar.xml with following code.

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar 
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:local="http://schemas.android.com/apk/res-auto"
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:layout_alignParentTop="true"
android:layout_gravity="bottom"
local:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
local:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

and in the styles.xml

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

<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
    <item name="windowNoTitle">true</item>
    <item name="windowActionBar">false</item>
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
</style>

Finally, include the toolbar inside layout

<include
        android:id="@+id/toolbar"
        layout="@layout/toolbar" />

   <!-- ToolBar -->
    <style name="ToolBarTheme.ToolBarStyle"    parent="ThemeOverlay.AppCompat.Dark.ActionBar">
        <item name="android:textColorPrimary">@android:color/white</item>
        <item name="android:textColor">@color/white</item>
        <item name="android:textColorPrimaryInverse">@color/white</item>
    </style>

Too late to post, this worked for me to change the color of the back button

Change your Toolbar Theme to ThemeOverlay.AppCompat.Dark

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/navigation"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@color/colorPrimary"
    android:orientation="vertical"
    app:theme="@style/ThemeOverlay.AppCompat.Dark">

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

and set it in activty

mToolbar = (Toolbar) findViewById(R.id.navigation);
setSupportActionBar(mToolbar);

回答7:

Well there is a more easy way to do this

drawerToggle = new ActionBarDrawerToggle(this, drawer, toolbar, R.string.open_drawer, R.string.close_drawer);
arrow = drawerToggle.getDrawerArrowDrawable();

And then

arrow.setColor(getResources().getColor(R.color.blue);

回答8:

This code works for me:

public static Drawable changeBackArrowColor(Context context, int color) {
    String resName;
    int res;

    resName = Build.VERSION.SDK_INT >= 23 ? "abc_ic_ab_back_material" : "abc_ic_ab_back_mtrl_am_alpha";
    res = context.getResources().getIdentifier(resName, "drawable", context.getPackageName());

    final Drawable upArrow = context.getResources().getDrawable(res);
    upArrow.setColorFilter(color, PorterDuff.Mode.SRC_ATOP);

    return upArrow;
}

...

getSupportActionBar().setHomeAsUpIndicator(changeBackArrowColor(this, Color.rgb(50, 50, 50)));               
supportInvalidateOptionsMenu();

Also, if you want to change the toolbar text color:

Spannable spannableString = new SpannableString(t);
spannableString.setSpan(new ForegroundColorSpan(Color.rgb(50, 50, 50)), 0, t.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
toolbar.setText(spannableString);

Working from API 19 through 25.

回答9:

Instead of style changes, just put these two lines of code to your activity.

getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeAsUpIndicator(R.drawable.arrowleft);

回答10:

Instead of using older drawable id "abc_ic_ab_back_material", use the new one abc_ic_ab_back_material in every api version. I have tested it in 19, 21, 27 and working fine with below code and configuration.

minSdkVersion = 17
targetSdkVersion = 26

compileSdkVersion = 27

public static Drawable changeBackArrowColor(Context context, int color) {
int res;
res = context.getResources().getIdentifier("abc_ic_ab_back_material", "drawable", context.getPackageName());
if (res == 0)
    return null;
final Drawable upArrow = ContextCompat.getDrawable(context, res);
upArrow.setColorFilter(ContextCompat.getColor(context, color), PorterDuff.Mode.SRC_ATOP);

return upArrow;

}
