Android 沉浸式statusbar （5.0以上无阴影，statusbar背景全透明）

1. android :fitsSystemWindows= "true"

只能配置在Activity，使自定义布局能占据statusbar

2.如果是继承了AppCompatActivity

在manifests设置

android:theme="@style/Theme.AppCompat.Light.NoActionBar">

3.如果希望状态栏没有阴影，背景颜色自定义在Activity中加：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
    setTranslucentStatus(true);
}


if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    Window window = getWindow();
    window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS
            | WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
    window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
            | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
    window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
    window.setStatusBarColor(Color.parseColor("#4cb86a"));
    window.setNavigationBarColor(Color.TRANSPARENT);
} else {
    SystemBarTintManager tintManager = new SystemBarTintManager(this);
    tintManager.setStatusBarTintEnabled(true);
    tintManager.setStatusBarTintResource(R.color.colorPrimary);//通知栏所需颜色*/
}

@TargetApi(19)
private void setTranslucentStatus(boolean on) {
    Window win = getWindow();
    WindowManager.LayoutParams winParams = win.getAttributes();
    final int bits = WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS;
    if (on) {
        winParams.flags |= bits;
    } else {
        winParams.flags &= ~bits;
    }
    win.setAttributes(winParams);
}

4.如果希望状态栏没有阴影，像qq空间 动态 页面，状态栏 直接 是 一张背景图片在Activity中加：

必须去掉布局的android:fitsSystemWindows="true"

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
    setTranslucentStatus(true);
}

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    Window window = getWindow();
    window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS
            | WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
    window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
            | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
    window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
    window.setStatusBarColor(Color.TRANSPARENT);
    window.setNavigationBarColor(Color.TRANSPARENT);
}else {
    SystemBarTintManager tintManager = new SystemBarTintManager(this);
    tintManager.setStatusBarTintEnabled(true);
    tintManager.setStatusBarTintColor(Color.TRANSPARENT);
}
