styles文件修改

新建一个values-v23文件夹，建立styles.xml，然后建一个同名的theme

    <style name="Theme.In.NoActionBar" parent="@android:style/Theme.DeviceDefault.Light.NoActionBar">
        <item name="android:windowActionBar">false</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:statusBarColor">@android:color/transparent</item>
        <item name="android:windowLightStatusBar">true</item>
        <item name="android:windowTranslucentStatus">true</item>
    </style>

基类BaseActivity修改

1.获取状态栏高度

    public static int getStatusBarHeight(Context context) {
        Class<?> c = null;
        Object obj = null;
        Field field = null;
        int x = 0, statusBarHeight = 0;
        try {
            c = Class.forName("com.android.internal.R$dimen");
            obj = c.newInstance();
            field = c.getField("status_bar_height");
            x = Integer.parseInt(field.get(obj).toString());
            statusBarHeight = context.getResources().getDimensionPixelSize(x);
        } catch (Exception e1) {
            e1.printStackTrace();
        }
        return statusBarHeight;
    }

2.添加对于顶部栏的marginTop属性

        if (Build.VERSION.SDK_INT >= 23){
            View decorView = getWindow().getDecorView();
            View contentView = decorView.findViewById(android.R.id.content);
            LinearLayout.LayoutParams layoutParams = (LinearLayout.LayoutParams) contentView.getLayoutParams();
            layoutParams.topMargin = DisplayUtil.getStatusBarHeight(this);
            contentView.setLayoutParams(layoutParams);
        }

特殊场景兼容

代码动态修改状态栏颜色
设置状态栏字体黑色

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

设置状态栏字体白色

  getActivitySafely().getWindow().getDecorView().setSystemUiVisibility(0);
