android 沉浸式之改变小米魅族状态栏颜色

这个是基于SystemBarTintManager更改的

增加一个方法:用于更改MIUIV6系统上的状态栏字体颜色 ,目前我仅仅只发现MIUIV6上可以更改,在android5.0上以及其它4.4以上系统没有发现可以更改字体颜色的代码

核心代码:

    public void setStatusBarDarkMode(boolean darkmode, Activity activity) {  if (sIsMiuiV6) {  Class<? extends Window> clazz = activity.getWindow().getClass();  try {  int darkModeFlag = 0;  Class<?> layoutParams = Class.forName("android.view.MiuiWindowManager$LayoutParams");  Field field = layoutParams.getField("EXTRA_FLAG_STATUS_BAR_DARK_MODE");  darkModeFlag = field.getInt(layoutParams);  Method extraFlagField = clazz.getMethod("setExtraFlags", int.class, int.class);  extraFlagField.invoke(activity.getWindow(), darkmode ? darkModeFlag : 0, darkModeFlag);  } catch (Exception e) {  e.printStackTrace();  }  }  }

用法:

    public void initSystemBar(){  if (VERSION.SDK_INT >= VERSION_CODES.KITKAT) {  getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);  getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);  getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);  fwRootLayout.setFitsSystemWindows(true);//需要把根布局设置为这个属性 子布局则不会占用状态栏位置  fwRootLayout.setClipToPadding(true);//需要把根布局设置为这个属性 子布局则不会占用状态栏位置  }  tintManager = new SystemBarTintManager(this);// 创建状态栏的管理实例  tintManager.setStatusBarTintEnabled(true);// 激活状态栏设置  tintManager.setNavigationBarTintEnabled(true);// 激活导航栏设置  tintManager.setStatusBarTintColor(getResources().getColor(R.color.blue500));//设置状态栏颜色  tintManager.setStatusBarDarkMode(false, this);//false 状态栏字体颜色是白色 true 颜色是黑色  }
