这是布局我的主要活动：
an this is the layout of my Mainactivity :
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
style="@style/HeaderBar"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?actionBarSize"
android:theme="@style/ActionBarThemeOverlay"
app:popupTheme="@style/ActionBarPopupThemeOverlay"
app:titleTextAppearance="@style/ActionBar.TitleText"/>
<android.support.design.widget.TabLayout
android:id="@+id/sliding_tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabSelectedTextColor="@color/tabSelectedTextColor"
app:tabTextColor="@color/tabTextColor"
app:tabIndicatorColor="@color/tabIndicatorColor"
app:tabGravity="fill"
app:tabMode="fixed"/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="@+id/view_pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
<android.support.design.widget.FloatingActionButton
android:id="@+id/fab_add"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="@dimen/fab_margin"
android:src="@drawable/fab_ic_add"
app:backgroundTint="@color/fab_normal"
app:layout_anchor="@+id/container"
app:layout_anchorGravity="bottom|right|end"
app:elevation="4dp"/>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/background_title"
android:layout_gravity="bottom|center"
android:layout_marginBottom="6dp"/>
</android.support.design.widget.CoordinatorLayout>
这是我的垃圾邮件屏幕代码：
and this is my spash screen code:
public class SplashscreenActivity extends Activity {
/** Splash screen duration time in milliseconds */
private static final int DELAY = 1000;
@Override
protected void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splashscreen);
// Jump to MainActivity after DELAY milliseconds
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
final Intent intent = new Intent(SplashscreenActivity.this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
intent.putExtra(MainActivity.OPENED_FROM_LAUNCHER, true);
startActivity(intent);
finish();
}
}, DELAY);
}
@Override
public void onBackPressed() {
// do nothing. Protect from exiting the application when splash screen is shown
}
}
这是我的初始屏幕的布局：
and this is layout of my splash screen :
<merge xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".SplashscreenActivity" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginBottom="70dp"
android:scaleType="center"
android:src="@drawable/nordic_logo" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/background_title"
android:layout_gravity="bottom|center"
android:layout_marginBottom="6dp"/>
有人可以告诉我如何解决这个问题？
can anyone tell me how to solve this issue?
推荐答案
这开始发生在支持设计库v.23.2.0
This started to happened in support design library v.23.2.0
compile 'com.android.support:design:23.2.0'
我知道这是从v23.2.0开始的，因为我的应用之前（版本23.1.2）运行良好，并在更新后开始出现相同的故障。
I know this started with v23.2.0 because my app was working fine before (v.23.1.2) and started to present same failure after update.
错误很简单：
您的一个视图固定在其父协调器布局上。但是，从23.2.0版开始，这不再允许。
One of your views is anchored to its parent Coordinator Layout. However, starting at v.23.2.0, this is no longer allowed.
我认为错误出在您的FAB中：
I think the error is in your FAB:
<android.support.design.widget.FloatingActionButton
android:id="@+id/fab_add"
...
app:layout_anchor="@+id/container"
... />
我相信 id /容器是一个父级CoordinatorLayout
I believe that id/container is a parent CoordinatorLayout
修复
正确的方法是更改 layout_anchor 并使用其他视图作为锚点（父布局或固定在屏幕底部的任何其他视图）。
Right way is change the layout_anchor and use another view as anchor (parent Layout or any other view which is fixed to bottom of the screen).
