禁用半透明状态栏后的DrawerLayout神器答案

【问题标题】：DrawerLayout artifact after disable translucent status bar禁用半透明状态栏后的DrawerLayout神器
【发布时间】：2016-07-22 09:48:54
【问题描述】：

先开启半透明状态栏

getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);       
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);

需要动态禁用后

getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);

禁用后显示奇怪的工件（半透明线），就像图片上的一样

UPDgithub上的示例项目

【解决方案1】：

经过研究，我找到了解决方案并编写了自定义类

public class DrawableLayoutFullScreen extends DrawerLayout {

    public DrawableLayoutFullScreen(Context context) {
        this(context,null);
    }

    public DrawableLayoutFullScreen(Context context, AttributeSet attrs) {
        super(context, attrs);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            setOnApplyWindowInsetsListener((v, insets) -> {
                final DrawableLayoutFullScreen drawerLayout = (DrawableLayoutFullScreen) v;
                drawerLayout.setWillNotDraw(insets.getSystemWindowInsetTop() <= 0 && getBackground() == null);
                drawerLayout.requestLayout();
                return insets.consumeSystemWindowInsets();
            });
        }
    }

    @Override
    public void setFitsSystemWindows(boolean fitSystemWindows) {
        if (fitSystemWindows) {
            setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
        } else {
            setSystemUiVisibility(0);
        }
        super.setFitsSystemWindows(fitSystemWindows);
    }
}

当调用setFitsSystemWindows(true)DrawableLayoutFullScreen 填充窗口并在状态栏上方绘制。之后需要为子视图设置填充和边距
