Within the ActionBar, I am trying to left align the logo and also display the Activity title. I'm finding it difficult to left align the logo.... and also display the logo and the title together.
My Activity is extending AppCompatActivity. I am using the styles.xml to provide the theme to the app. In the styles.xml theme, I have the following:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="actionBarStyle">#style/ActionBarLogoTheme</item>
</style>
Which calls the following:
<style name="ActionBarLogoTheme" parent="#style/Widget.AppCompat.Light.ActionBar.Solid.Inverse">
<item name="logo">#drawable/logo</item>
<item name="displayOptions">useLogo|showHome|showTitle</item>>
<item name="android:layout_gravity">left</item>
<item name="android:gravity">left</item>
</style>
In the above, the 'gravity' and 'layout_gravity' don't seem to take affect, and also the 'showTitle' display option doesn't seem to take affect also. Would anyone be able to help. The following illustrates what it currently looks like, and what I would like it to look like.
Thank you all.
If you want to use an ActionBar you can use:
<style name="ActionBar" parent="Widget.AppCompat.Light.ActionBar.Solid.Inverse">
<item name="displayOptions">showHome|useLogo|showTitle</item>
<item name="logo">#drawable/....</item>
</style>
You can also it programmatically:
getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setDisplayUseLogoEnabled(true);
getSupportActionBar().setLogo(R.drawable....);
getSupportActionBar().setTitle("Title");
But you can also use a Toolbar:
Toolbar toolbar = findViewById(R.id.toolbar);
toolbar.setNavigationIcon(R.drawable.ic_menu_camera);
setSupportActionBar(toolbar);

In Android, is there any way to give an ActionMode the same appearance as the normal Toolbar? Currently my ActionMode looks different to the Toolbar in that the background is slightly brighter (at least using Theme.AppCompat.NoActionBar), the MenuItems are fully black/white (depending on the theme) instead of colorControlNormal (which I set them to) and most annoyingly, there is an underline under the ActionMode that I can't seem to get rid of. Instead, I'm trying to make the ActionMode indistinguishable from the Toolbar.
The Toolbar (also what the ActionMode is meant to look like):
What the ActionMode currently looks like:
Any help would be highly appreciated!
For changing the background color of ActionMode & Remove the bottom line. You can use actionModeStyle where you can set background to your desired color.
For changing the icon color you can set colorControlNormal inside the actionBarTheme.
So your theme would look like this:
<style name="Theme.AppTheme" parent="Theme.MaterialComponents.DayNight.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<!--add this-->
<item name="actionModeStyle">#style/ActionModeStyle</item>
<item name="actionBarTheme">#style/MyActionBarTheme</item>
</style>
<style name="MyActionBarTheme" parent="ThemeOverlay.AppCompat.Dark.ActionBar">
//replace with your own desired color
<item name="colorControlNormal">#a00</item>
</style>
<style name="ActionModeStyle" parent="#style/Widget.AppCompat.ActionMode">
//replace with your own desired color
<item name="background">#color/colorPrimary</item>
<item name="titleTextStyle">#style/ActionModeTitleTextStyle</item>
</style>
<style name="ActionModeTitleTextStyle" parent="#style/TextAppearance.AppCompat.Widget.ActionMode.Title">
//replace with your own desired color
<item name="android:textColor">#a00</item>
</style>
I'm trying to use app:collapsedTitleTextAppearance for my title while collaping toolbar layout is collapsed and showing toolbar only.
this is my problem:
I have used app:collapsedTitleTextAppearance and this is the style:
<style name="about_title">
<item name="android:paddingRight">100dp</item>
<item name="android:layout_marginRight">10dp</item>
</style>
How can I fix this?
I am trying to add an actionbar similar to soundclouds. I am following the instructions on how to customize the action bar on the android developer website. The error seems to be that the action bar is already being supplied but I am trying to create another one.
java.lang.IllegalStateException: This Activity already has an action bar supplied by the window decor. Do not request Window.FEATURE_SUPPORT_ACTION_BAR and set windowActionBar to false in your theme to use a Toolbar instead.
Here is onCreate():
Toolbar toolbar = (Toolbar) findViewById(R.id.main_toolbar);
setSupportActionBar(toolbar);
addBirthdayFragment();
Here is the layout file:
<?xml version="1.0" encoding="utf-8"?>
<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"
xmlns:app="http://schemas.android.com/apk/res-auto"
tools:context=".view.MainActivity">
<android.support.v7.widget.Toolbar
android:id="#+id/main_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:elevation="4dp"
android:theme="#style/ThemeOverlay.AppCompat.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"/>
</RelativeLayout>
I have tried to just remove the xml code and java code for the toolbar, in the layout and onCreate respectively, however this is not working; the same error still persists. It must be something to do with the theme I am using, but I do not know what exactly. It confuses me because the theme is the default one so I did not expect this.
Here is my theme:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
Side question:
I am trying to achieve the look of the soundcloud action bar, which appears to be tabbed. Is this the way I should go if I want this result, or is there some other widget that is used for tabbed action bars?
Thank you for the help.
Android is complaining because you never told it that you will use a Toolbar instead of the Android-provided ActionBar. To let Android know about this, you need to add these to your style:
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
If you'd like to use the Android ActionBar sometimes and a Toolbar of yours some other time, you can add the above two lines to a new style extending your AppTheme, and using that on AndroidManifest.xml:
<!-- Use this one in the Manifest when you want to use the native ActionBar -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- your styling here -->
</style>
<!-- Use this one when you want to implement your own Toolbar -->
<style name="AppTheme.NoActionBar" parent="AppTheme">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
Your code is:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
The line parent="Theme.AppCompat.Light.DarkActionBar" says dark action bar. you need to change it to NoActionBar.
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
I have been wrestling with trying to get my PreferenceFragment to have the same Material-based theme and styling (via AppCompat) as the rest of my application. The PreferenceFragment that I am using to manage all of my application settings is shown below:
As you can see from the screenshot above, I was able to customize the PreferenceFragment by using colorAccent, colorPrimary, and a few other attributes. My theme for the PreferenceFragment is as follows:
<style
name="settingsTheme"
parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimary">#color/blue_grey_500</item>
<item name="colorAccent">#color/blue_grey_500</item>
<item name="android:textColor">#color/black_text_alt</item>
<item name="android:textColorSecondary">#color/black_secondary_text</item>
</style>
However, despite my best efforts, I am unable to apply themes to the individual elements within my PreferenceFragment, such as ListPreference and EditTextPreference; all of the preferences still retain the standard AppCompat theme:
I found an 2 year old post that discusses this issue, albeit with no real solution: How to apply theme to <PreferenceScreen> elements of a <PreferenceCategory>
I am wondering if anyone has been able to successfully apply themes to the preferences since AppComat V21 has been released. If not, are there any viable workarounds that can be used to apply custom themes to individual preferences?
UPDATE: I made a library to battle the issue (uses AppCompat r22): https://github.com/consp1racy/android-support-preference
The ListPreference extends DialogPreference which uses this piece of code to create the dialog:
mBuilder = new AlertDialog.Builder(context)
.setTitle(mDialogTitle)
.setIcon(mDialogIcon)
.setPositiveButton(mPositiveButtonText, this)
.setNegativeButton(mNegativeButtonText, this);
As you can see the AlertDialog.Builder constructor is not supplied with the second optional int theme parameter. That means the dialog will be themed by whatever your activity's theme has in its android:alertDialogTheme attribute.
Now you have to create a custom theme for your dialog which derives from Theme.AppCompat.Dialog like so:
<style name="Theme.YourApp.Dialog.Alert" parent="Theme.AppCompat.Light.Dialog">
<item name="android:windowBackground">#android:color/transparent</item>
<item name="android:windowContentOverlay">#null</item>
<item name="android:windowMinWidthMajor">#android:dimen/dialog_min_width_major</item>
<item name="android:windowMinWidthMinor">#android:dimen/dialog_min_width_minor</item>
<item name="colorAccent">#color/accent_yourapp</item>
<item name="colorPrimary">#color/primary_yourapp</item>
<item name="colorPrimaryDark">#color/primary_dark_yourapp</item>
</style>
Problem 1: The above solution will not work for RingtonePreference because it does not extend ListPreference but calls a ringtone chooser intent, so it's always themed according to system. Check out this answer:
RingtonePreference Theme So we can mark this as solved.
Problem 2: The AppCompat dialogs lack title. And so far I haven't found a way to fix this. True that I am not looking hard enough. Let's ignore the title absence as a minor issue.
Problem 3: The radio button drawables are not mutated so the graphics are inconsistent between passive and active (colored) state - all are colored (not just the one you!re pressing) or all are grey. Now this is really annoying
Problems 2 & 3 forced me to take another route - my dialog theme looks like this on API 14+
<style name="Theme.MyApp.Dialog.Alert" parent="android:Theme.DeviceDefault.Light.Dialog.MinWidth">
<item name="android:windowBackground">#android:color/transparent</item>
<item name="android:windowContentOverlay">#null</item>
</style>
and like this on API 21+
<style name="Theme.YourApp.Dialog.Alert" parent="android:Theme.DeviceDefault.Light.Dialog.MinWidth">
<item name="android:colorPrimary">#color/primary_yourapp</item>
<item name="android:colorPrimaryDark">#color/primary_dark_yourapp</item>
<item name="android:colorAccent">#color/accent_yourapp</item>
</style>
These values have been experimentally gained by crawling through the platform's source files and well tested.
The point is that the only reliable solution seems to be using the device default dialog theme. The only choice before Lollipop is a light or dark variant. On Lollipop this will work as intended and requested.
EDIT: Since appcompat-v7-r21.1.0 you can use AppCompatDialog which is material themed variant of native AlertDialog.
You can use provided AlertDialog.Builder (not to be confused with its native counterpart) for creating its instances.
DialogPreference uses android.app.AlertDialog.Builder directly so it would be impossible to switch the displayed dialog to the material design one for all API levels (which requires using android.support.v7.widget.AlertDialog.Builder).
I believe the only option for now is to extend and override dialog creation logic in DialogPreference or its subclasses (and use reflection to work around private accessors if required). Check out this reddit thread and an example AppCompatListPreference made by the author of that thread.
Taking cues from the answers already given I set in the manifest a custom theme for Settings activity because it is necessary to remove the border background around the Dialog that appear, using a transparent background this only for API <21:
AndroidManifest.xml
<application
android:name=".MyApplication"
...
android:theme="#style/AppTheme">
...
<activity
android:name=".ui.SettingsActivity"
...
android:theme="#style/AppTheme.Settings">
</activity>
</application>
values/style.xml
<!-- Application theme -->
<style name="AppTheme" parent="AppTheme.Base">
<!-- All customizations that are NOT specific to a particular API-level can go here. -->
</style>
<style name="AppTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">
...
<item name="android:alertDialogTheme">#style/AppTheme.AlertDialog</item>
</style>
<!-- Must be different because of transparent background -->
<style name="AppTheme.Settings" parent="AppTheme.Base">
<item name="android:alertDialogTheme">#style/AppTheme.SettingsAlertDialog</item>
</style>
<style name="AppTheme.AlertDialog" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="android:windowMinWidthMajor">#android:dimen/dialog_min_width_major</item>
<item name="android:windowMinWidthMinor">#android:dimen/dialog_min_width_minor</item>
<item name="android:windowContentOverlay">#null</item>
<item name="colorAccent">#color/accent_light</item>
<item name="colorControlActivated">#color/accent_light</item>
<item name="colorControlHighlight">#color/primary_highlight</item>
</style>
<style name="AppTheme.SettingsAlertDialog" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="android:windowMinWidthMajor">#android:dimen/dialog_min_width_major</item>
<item name="android:windowMinWidthMinor">#android:dimen/dialog_min_width_minor</item>
<item name="android:windowBackground">#android:color/transparent</item>
<item name="android:windowContentOverlay">#null</item>
<item name="colorAccent">#color/accent_light</item>
<item name="colorControlActivated">#color/accent_light</item>
<item name="colorControlHighlight">#color/primary_highlight</item>
</style>
finally for values-v21/style.xml the normal dialog, if you don't put this in v21 dialogs will be transparent.
<style name="AppTheme.Settings" parent="AppTheme.Base">
<item name="android:alertDialogTheme">#style/AppTheme.AlertDialog</item>
</style>
Actually I've the problem to set the colors directly from the Theme attributes: ?android:colorAccent instead of my fixed color #color/accent_light.
You should check out this Gist about how different components use the theme color attributes. You might need to add the following attributes to your theme to get the effect you want:
<item name="colorControlNormal">#color/x_color</item>
<item name="colorControlActivated">#color/y_color</item>
<item name="colorControlHighlight">#color/z_color</item>
I'm having trouble with android app.
I try to make my action bar transparent (like google maps or google play music) but instead of becoming transparent it becomes white.
Here is my custom theme:
<!-- the theme applied to the application or activity -->
<style name="CustomActionBarTheme" parent="#android:style/Theme.Holo.Light.DarkActionBar">
<item name="android:actionBarStyle">#style/MyActionBar</item>
<item name="android:windowActionBarOverlay">true</item>
</style>
<!-- ActionBar styles -->
<style name="MyActionBar" parent="#android:style/Widget.Holo.Light.ActionBar.Solid.Inverse">
<item name="android:titleTextStyle">#style/MyActionBarTitleText</item>
<item name="android:background">#android:color/transparent</item>
<item name="android:logo">#android:color/transparent</item>
</style>
<!-- ActionBar title text -->
<style name="MyActionBarTitleText" parent="#android:style/TextAppearance.Holo.Widget.ActionBar.Title">
<item name="android:textColor">#FFFFFF</item>
</style>
Has anyone got any ideas why is that happening ?
EDIT 1:
I forgot to mention that I'm using fragments. So I have only one activity with Navigation Drawer and a fragment inside. The fragment itself contains a listview.
Thank you all in advance !
You can try the answer in this thread: Transparent Actionbar: custom tabcolor
getWindow().requestFeature(Window.FEATURE_ACTION_BAR_OVERLAY);
ActionBar actionBar = getActionBar();
actionBar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#330000ff")));
actionBar.setStackedBackgroundDrawable(new ColorDrawable(Color.parseColor("#550000ff")));
The one changes the color of the ActionBar and the other the color of the tabs attached to it.
If you want to make it completely transperant then your first number of the color should be 00: #00123456, because the colors are in the (Alpha, Red, Green, Blue) schema.
