I want to make my top status bar transparent using below code, which make status bar transparent but also make bottom navigation bar transparent.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
Window w = getWindow(); // in Activity's onCreate() for instance
// getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
w.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
// w.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION, WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
// w.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
w.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
}
I want to make bottom navigation bar opaque like below.
I want to make only status bar transparent not bottom navigation bar. So please help me as i am new in android
Although it work nice in kitkat as below i want, but not above kitkat.
It can be done using
<item name="android:navigationBarColor">#color/theme_color</item>
or
window.setNavigationBarColor(#ColorInt int color)
http://developer.android.com/reference/android/view/Window.html#setNavigationBarColor(int)
will work for API level 21+

The following code successfully hides the system's navigation bar from the screen. Users can still swipe up to reveal the navigation bar, which will remain on screen for a few seconds, then disappear again.
Is there a callback to detect when the navigation bar appears and disappears, as the user swipes up, and afterwards, when the navigation bar automatically hides?
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
getWindow().setDecorFitsSystemWindows(false);
if (getWindow().getInsetsController() != null) {
getWindow().getInsetsController().hide(WindowInsets.Type.navigationBars());
getWindow().getInsetsController().setSystemBarsBehavior(WindowInsetsController.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE);
}
} else {
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION |
View.SYSTEM_UI_FLAG_HIDE_NAVIGATION |
View.SYSTEM_UI_FLAG_LAYOUT_STABLE |
View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
);
}
The code below (taken from the docs) seems to detect when the navigation bar is hidden on launch, but not when the user swipes up to reveal it, or when it disappears afterwards.
View decorView = getWindow().getDecorView();
decorView.setOnSystemUiVisibilityChangeListener
(new View.OnSystemUiVisibilityChangeListener() {
#Override
public void onSystemUiVisibilityChange(int visibility) {
// Note that system bars will only be "visible" if none of the
// LOW_PROFILE, HIDE_NAVIGATION, or FULLSCREEN flags are set.
if ((visibility & View.SYSTEM_UI_FLAG_FULLSCREEN) == 0) {
// TODO: The system bars are visible. Make any desired
// adjustments to your UI, such as showing the action bar or
// other navigational controls.
} else {
// TODO: The system bars are NOT visible. Make any desired
// adjustments to your UI, such as hiding the action bar or
// other navigational controls.
}
}
});
Is there a callback to detect when the navigation bar appears and disappears, as the user swipes up, and afterwards, when the navigation bar automatically hides?
You can't detect that, a user's swipe to show the navigation bar or the status bar isn't a part of your app, it's the system responsibility that runs in a different process than your app's.
Actually your app's window isn't affected on that swipe; and hence the bars are laid on top of your activity (without any extra insets) and that is an evidence that it's related to the system window instead. So, any listener within your app's process/window can't help on that.

In guidelines of Android 5.0, the navigation bar seems customizable:
http://www.google.com/design/spec/layout/structure.html#structure-system-bars
How can I change the navigation bar color?
I would like to use a white style.
Screenshots:
Edit: In my resources, I tested the style:
<item name="android:navigationBarColor" tools:targetApi="21">#android:color/white</item>
But the buttons are white. I would like the same renderer as the second image.
Starting from API 27, it is now possible to use the light style of the navigation bar:
<item name="android:navigationBarColor">#android:color/white</item>
<item name="android:windowLightNavigationBar">true</item>
From the documentation:
windowLightNavigationBar
If set, the navigation bar will be drawn such that it is compatible with a light navigation bar background.
For this to take effect, the window must be drawing the system bar
backgrounds with windowDrawsSystemBarBackgrounds and the navigation
bar must not have been requested to be translucent with
windowTranslucentNavigation. Corresponds to setting
SYSTEM_UI_FLAG_LIGHT_NAVIGATION_BAR on the decor view.
Use this in your Activity.
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
getWindow().setNavigationBarColor(getResources().getColor(R.color.green));
}
add this line in your v-21/style
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">#android:color/transparent</item>
<item name="android:navigationBarColor">#android:color/black</item>
</style>
This code changes the navigation bar color according to your screen background color:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
getWindow().setNavigationBarColor(ContextCompat.getColor(this, R.color.any_color));
}
You can also use the light style for the navigation bar:
<item name="android:navigationBarColor">#android:color/white</item>
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
getWindow().setNavigationBarColor(getResources().getColor(R.color.colorWhite));
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LIGHT_NAVIGATION_BAR); //For setting material color into black of the navigation bar
}
Use this one if your app's API level is greater than 23
getWindow().setNavigationBarColor(ContextCompat.getColor(MainActivity.this, R.color.colorWhite));
getWindow().getDecorView().setSystemUiVisibility(SYSTEM_UI_FLAG_LIGHT_NAVIGATION_BAR);
May this code will not work for API level 30. Because " SYSTEM_UI_FLAG_LIGHT_NAVIGATION_BAR" is deprecated in API level 30.
Check this out: https://developer.android.com/reference/android/view/View#SYSTEM_UI_FLAG_LIGHT_NAVIGATION_BAR
the navigation bar is not supposed to be colored
When you customize the navigation and status bars, either make them both transparent or modify only the status bar. The navigation bar should remain black in all other cases.
(source https://developer.android.com/training/material/theme.html )
BUT, you can use this library to achieve what you want :) https://github.com/jgilfelt/SystemBarTint
You can also set light system navigation bar in API 26 programmatically:
View.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LIGHT_NAVIGATION_BAR);
Where View coluld be findViewById(android.R.id.content).
However remember that:
For this to take effect, the window must request FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS but not FLAG_TRANSLUCENT_NAVIGATION.
See documentation.
getWindow().setNavigationBarColor(ContextCompat.getColor(MainActivity.this,R.color.colorPrimary)); //setting bar color
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR); //additional setting items to be black if using white ui
Old question. But at this time we have a direct solution. May be helpful for someone.
public static void setNavigationBarColor(Activity activity, int color, int divColor) {
Window window= activity.getWindow();
window.setNavigationBarColor(color);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
window.setNavigationBarDividerColor(divColor);
}
}

I'm making a custom keyboard for android, full screen, i want to hide the navigation bar and the status bar on Android only when keyboard is shown and then return the same state.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
getWindow().setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS)
}
Use the above given code to hide the status bar from the app. Also, don't forget to apply your keyboard visible condition.
I'm developing a app for a specific tablet running android 4.4.4. Users aren't allowed to close the app. I hoped there was a way to completely hide or disable the navigation bar but I can't seem to find a solution. I've already tried to use the method explained on Using Immersive fullscreen but is doesn't seem to have any effect. Any suggestions?
You can hide the navigation bar using the SYSTEM_UI_FLAG_HIDE_NAVIGATION flag.
Try this code
View decorView = getWindow().getDecorView();
// Hide both the navigation bar and the status bar.
// SYSTEM_UI_FLAG_FULLSCREEN is only available on Android 4.1 and higher, but as
// a general rule, you should design your app to hide the status bar whenever you
// hide the navigation bar.
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
i am new in android programming!
i want a full screen image like Hill Climb Racing (as you can see below)
i try to use
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
but it just disappear action bar and i want to disappear both action bar and android default key bar (home button, back and the another one)
If you are targeting android 4.0 and higher
View decorView = getWindow().getDecorView();
// Hide both the navigation bar and the status bar.
// SYSTEM_UI_FLAG_FULLSCREEN is only available on Android 4.1 and higher, but as
// a general rule, you should design your app to hide the status bar whenever you
// hide the navigation bar.
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
Check this developer site for more detail information
try this in your activity on the manifest
android:theme="#android:style/Theme.NoTitleBar.Fullscreen"
