Change navigation bar color, Android - java

How can I change the color/transparency of the Navigation Bar from black to a generic color in pre-Lollipop devices (e.g. the color of the status bar or of the action bar)?
Can I do it using AppCompat or is it only possible for SDK 21?

You can set the attribute navigationBarColor in an AppCompat theme, or android:navigationBarColor in a native v21 theme.
<style name="AppTheme" parent="#style/Theme.AppCompat.Light">
...
<item name="navigationBarColor">#123456</item>
</style>
https://developer.android.com/training/material/theme.html#StatusBar
Note that this does not work on Pre-Lollipop devices, since this feature needs to be supported by the system, which is not the case on Android 4.4 or older.

Another programmatically way:
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.setStatusBarColor(getResources().getColor(R.color.DarkOrange));
window.setNavigationBarColor(getResources().getColor(R.color.red));
Further, to change your status bar color, add the following line:
window.setStatusBarColor(getResources().getColor(R.color.green));

style-v21
<resources>
<style name="Theme.DesignDemo" parent="Base.Theme.DesignDemo">
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:windowTranslucentNavigation">true</item>//translucent
<item name="android:statusBarColor">#android:color/transparent</item>
<item name="android:navigationBarColor">#android:color/transparent</item>
</style>

Applying AppCompat theme to individual preferences in a PreferenceFragment

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>

Remove ActionBar shadow on Android L (API 21)

i'm tring to remove the ActionBar Shadow in Android L. On API 14 this code works
<style name="AppBaseTheme" parent="Theme.AppCompat.Light"/>
<style name="AppTheme" parent="AppBaseTheme">
<item name="android:windowContentOverlay">#null</item>
</style>
But if i put the same code into /values-v21 not works. Any idea on how can i solve? Thanks.
On Android 5.0, Action Bars use an elevation to provide the shadow. You can remove the elevation programmatically via getSupportActionBar().setElevation(0)

Android Dialog Shadow

I work with android and I used android-styled-dialogs project for custom dialogs
I have custom theme
<style name="DialogStyleDark.Custom">
<item name="dialogBackground">#color/tt_gray_2</item>
<item name="titleTextColor">#color/tt_light_blue</item>
<item name="titleSeparatorColor">#color/sdl_button_separator_dark</item>
<item name="messageTextColor">#color/sdl_message_text_dark</item>
<item name="buttonTextColor">#color/sdl_button_text_dark</item>
<item name="buttonSeparatorColor">#color/sdl_button_separator_dark</item>
<item name="buttonBackgroundColorNormal">#color/sdl_button_normal_dark</item>
<item name="buttonBackgroundColorPressed">#color/tt_gray_1</item>
<item name="buttonBackgroundColorFocused">#color/tt_gray_1</item>
</style>
dialog seems like this
I want to it has shadow as android native dialogs
Can anybody help me?
Since I did much research in how to customize and recolor the default holo dialogs I can tell you that this is done with drawables. So just create some nice png files with shadows and use them as background.
Here you can find the orginal xml file which is used by alert holo themed dialogs.

Action bar transparency

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.

Customize according to what you want. See the parent style #android:style/Widget.Holo.Light.ActionBar
<style name="Theme.Styled" parent="#android:style/Theme.Holo.Light">
<item name="android:actionBarStyle">#style/Widget.Styled.ActionBar</item>
</style>
<style name="Widget.Styled.ActionBar"
parent="#android:style/Widget.Holo.Light.ActionBar">
<item name="android:background">#drawable/ab_custom_solid_styled</item>
<item name="android:backgroundStacked"
