改变状态栏的颜色：

需要满足2个条件才有效。

1 API>=21，即Android5.0，
2 parent必须是AppCompat

方法一：通过Style来改变状态栏的颜色

通过设置Style.xml中的colorPrimaryDark属性来改变状态栏的颜色。

<!-- Base application theme. --><style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">    <!-- Customize your theme here. -->    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>    <item name="android:statusBarColor">@color/statusBarColor</item>    <item name="colorPrimary">@color/colorPrimary</item></style>

其他：

 <item name="android:textColorPrimary">@color/textColorPrimary</item> <item name="colorAccent">@color/colorAccent</item> <item name="android:windowBackground">@color/windowBackground</item> <item name="android:textColor">@color/textColor</item>

见下图：
这里写图片描述

Style中的属性含义 statusBarColor 状态栏背景色 colorPrimaryDark 状态栏背景色(若statusBarColor也存在，则以statusBarColor为主) colorPrimary 状态栏下面的Bar:ActionBar的背景色 colorAccent android:windowBackground 窗口背景色 textColorPrimary EditText的字体 textColor TextView的字体颜色

不一样的地方：

textColorPrimary显示的是EditText的字体颜色

方法二：状态栏将显示为纯净的颜色，没有渐变效果

/** * Created by ${cqc} on 2016/9/24. * 设置导航栏颜色 */public class StatusBarUtil {    //Activity    public static void setSattusBarColor(Activity activity,int colorResId){        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP){            Window window = activity.getWindow();            window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);            window.setStatusBarColor(activity.getResources().getColor(colorResId));            //设置底部导航栏颜色            window.setNavigationBarColor(activity.getResources().getColor(colorResId));        }    }    //Dialog    public static void setSattusBarColor(Dialog dialog, int colorResId){        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP){            Window window = dialog.getWindow();            window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);            window.setStatusBarColor(dialog.getContext().getResources().getColor(colorResId));            //设置底部导航栏颜色            window.setNavigationBarColor(dialog.getContext().getResources().getColor(colorResId));        }    }}

StatusBarDemo

隐藏状态栏

参考：
带你走进沉浸式状态栏

//隐藏状态栏View decorView = getWindow().getDecorView();//第一种   //decorView.setSystemUiVisibility(View.INVISIBLE);//gone无效，invisible有效//第二种decorView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN);

沉浸式

效果图

2种实现方式

同时隐藏顶部状态栏和底部导航栏

View decorView = getWindow().getDecorView();int uiOptions = decorView.getSystemUiVisibility();uiOptions ^= View.SYSTEM_UI_FLAG_HIDE_NAVIGATION;uiOptions ^= View.SYSTEM_UI_FLAG_FULLSCREEN;uiOptions ^= View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;decorView.setSystemUiVisibility(uiOptions);

或者

//隐藏状态栏和导航栏decorView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);//显示状态栏和导航栏decorView.setSystemUiVisibility(View.VISIBLE);

怎么判断沉浸式开启了没有

true：已经关闭；false：已经开启

boolean isImmersiveModeEnabled = ((uiOptions | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY) == uiOptions);if (isImmersiveModeEnabled) {    Log.i(TAG, "Turning immersive mode mode off. ");} else {    Log.i(TAG, "Turning immersive mode mode on.");}
