设置状态栏颜色

if (Build.VERSION.SDK_INT>21){getWindow().setStatusBarColor(getResources().getColor(R.color.mainc));}

方法2

<color name="colorPrimary">#3F51B5</color>

//取消标题

requestWindowFeature(Window.FEATURE_NO_TITLE);

//隐藏状态栏——全屏模式

1、方法1

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,

WindowManager.LayoutParams.FLAG_FULLSCREEN);

2、方法2

if (Build.VERSION.SDK_INT >= 19) {View decorView = getWindow().getDecorView();decorView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION| View.SYSTEM_UI_FLAG_FULLSCREEN| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);}

设置状态栏背景色，沉浸模式

if (Build.VERSION.SDK_INT >= 21) {View decorView = getWindow().getDecorView();int option = View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN| View.SYSTEM_UI_FLAG_LAYOUT_STABLE;decorView.setSystemUiVisibility(option);getWindow().setNavigationBarColor(Color.TRANSPARENT);getWindow().setStatusBarColor(Color.TRANSPARENT);}

设置状态栏字体色

getWindow().setNavigationBarColor(Color.TRANSPARENT);//底部软键盘背景色getWindow().setStatusBarColor(Color.TRANSPARENT);//状态栏背景色

getWindow().getDecorView().setSystemUiVisibility( View.SYSTEM_UI_FLAG_VISIBLE);//白色

// getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);//黑色
