使用android.support.design.widget.CoordinatorLayout出现空白快问题

实现沉浸式状态栏和隐藏效果后在CoordinatorLayout 22以前没什么问题，只是体验没有23的好，在升级到23后底部出现了一块空白，只要一滑动就出现，后来根据相关资料总算解决了  先看看布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:fitsSystemWindows="true">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="@android:color/white"
android:layout_gravity="center"
/>
<android.support.design.widget.CoordinatorLayout
android:id="@+id/root_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">

<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="true"
android:orientation="vertical"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

<LinearLayout
android:id="@+id/scroll_toolbar_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:orientation="vertical"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light">

//此次去掉相关的代码
</LinearLayout>

<android.support.design.widget.TabLayout
android:id="@+id/my_attention_and_follow_indicator"
android:layout_width="match_parent"
android:layout_height="54dp"
android:background="@color/white"/>
</android.support.design.widget.AppBarLayout>

<android.support.v4.view.ViewPager
android:id="@+id/my_atten_and_follow_viewpager"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
</android.suppor

这里只要设置toolbar和rootlayot的高度就行

//处理底部的黑块
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
getWindow().setStatusBarColor(getResources().getColor(android.R.color.transparent));
}
}

int statusBarHeight = SysUtil.getStatusBarHeight(this);
if (statusBarHeight > 0) {
int sunHeight = statusBarHeight + Utils.dip2px(this, 27);

ViewGroup.LayoutParams layoutParams = mToolbar.getLayoutParams();
layoutParams.height = sunHeight;
mToolbar.setLayoutParams(layoutParams);

View rootLayout = findViewById(R.id.root_layout);
rootLayout.setPadding(0, -statusBarHeight * 2, 0, 0);

}

这里设置是要在状态栏的基础上再加上标题栏的高度

int sunHeight = statusBarHeight + Utils.dip2px(this, 27);

设置好标题栏后再设置android.support.design.widget.CoordinatorLayout的pading值即可
