沉浸式状态栏是根据很多朋友的文章总结出来的，看的太多所以找不到出处了，十分抱歉，现在只是把这些代码从我的项目中拿出来做个记录。

Android5.0之后，状态栏颜色可直接设置
Android4.4至5.0，根据Activity找到android.R.content，在其中添加一个View(高度为statusbarHeight)

在super.onCreate(savedInstanceState)后加入此代码if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {    Window window = getWindow();    //需要设置这个 flag 才能调用 setStatusBarColor 来设置状态栏颜色    window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);    // 设置状态栏颜色    window.setStatusBarColor(getResources().getColor(R.color.state_bar_default));    ViewGroup mContentView = (ViewGroup) findViewById(Window.ID_ANDROID_CONTENT);    View mChildView = mContentView.getChildAt(0);    if (mChildView != null) {        //注意不是设置 ContentView 的 FitsSystemWindows, 而是设置 ContentView 的第一个子 View . 预留出系统 View 的空间.        ViewCompat.setFitsSystemWindows(mChildView, false);    }} else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT && Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {    Window window = getWindow();    window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);    ViewGroup mContentView = (ViewGroup) findViewById(Window.ID_ANDROID_CONTENT);    ViewGroup mContentParent = (ViewGroup) mContentView.getParent();    View statusBarView = mContentParent.getChildAt(0);    if (statusBarView != null && statusBarView.getLayoutParams() != null && statusBarView.getLayoutParams().height == getStatusHeight()) {        //避免重复调用时多次添加View        statusBarView.setBackgroundColor(getResources().getColor(R.color.state_bar_default));        return;    }    //创建一个假的 View, 并添加到 ContentParent    statusBarView = new View(this);    ViewGroup.LayoutParams lp = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, getStatusHeight());    statusBarView.setBackgroundColor(getResources().getColor(R.color.state_bar_default));    mContentParent.addView(statusBarView, 0, lp);    //ChildView 不预留空间    View mChildView = mContentParent.getChildAt(0);    if (mChildView != null) {        ViewCompat.setFitsSystemWindows(mChildView, false);    }}获取状态栏高度    private int getStatusHeight() {        int statusHeight = 0;        Rect localRect = new Rect();        getWindow().getDecorView().getWindowVisibleDisplayFrame(localRect);        statusHeight = localRect.top;        if (statusHeight == 0) {            Class<?> localClass;            try {                localClass = Class.forName("com.android.internal.R$dimen");                Object localObject = localClass.newInstance();                int i5 = Integer.parseInt(localClass.getField("status_bar_height").get(localObject).toString());                statusHeight = getResources().getDimensionPixelSize(i5);            } catch (Exception e) {                e.printStackTrace();            }        }        return statusHeight;    }
