查看無法錨定到父CoordinatorLayout

這不是我的應用程序，這是北歐應用程序，它的源代碼放在github上，我試圖在我的機器上運行soutce。但我一直有這個錯誤：查看無法錨定到父CoordinatorLayout

的，這是我Mainactivity的佈局：

<?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>

，這是我spash屏幕代碼：

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 
    } 

}

，這是佈局我的啓動畫面：

<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"/>

誰能告訴我如何解決這個問題？

這開始支持設計庫v.23.2.0

compile 'com.android.support:design:23.2.0'

我知道這開始v23.2.0，因爲我的應用程序是以前工作的罰款（v.23.1.2），並開始呈現發生更新後同樣失敗。

錯誤很簡單：

的你的意見

一個錨定在其父協調佈局。但是，從v.23.2.0開始，這不再被允許。

我認爲錯誤是在你的FAB：

<android.support.design.widget.FloatingActionButton 
    android:id="@+id/fab_add" 
    ... 
    app:layout_anchor="@+id/container" 
    ... />

我相信id/container是父母CoordinatorLayout

固定

正確的做法是改變layout_anchor和使用其他視圖錨點（父佈局或固定在屏幕底部的任何其他視圖）。

謝謝。問題解決了。 – farzaneh

變化應用程式：layout_anchor，不使用Coodinator

到FAB被錨定，其必須是CoordinatorLayout的後代視圖的視圖。

如果視圖是佈局，FAB一定不能在佈局內，否則錨定重力設置將不起作用。例如：

<android.support.design.widget.CoordinatorLayout 
    android:id="@+id/content_layout" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"> 
    . 
    . 
    . 
    <FrameLayout 
     android:id="@+id/attachment_layout" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" /> 

    <android.support.design.widget.FloatingActionButton 
     android:id="@+id/fab" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_marginEnd="@dimen/fab_margin_end" 
     android:layout_marginTop="@dimen/fab_margin_top" 
     android:scaleType="center" 
     android:src="@drawable/ic_action_save" 
     app:borderWidth="0dp" 
     app:elevation="@dimen/fab_elevation" 
     app:layout_anchor="@id/attachment_layout" 
     app:layout_anchorGravity="top|end" 
     app:rippleColor="@color/accent_highlight" /> 

</android.support.design.widget.CoordinatorLayout>

通過提供解釋如何實現答案的代碼，可以改進答案。 – MikeT

它添加一個名爲'attachment_layout'的子佈局，與'fab'具有相同的等級，所以'fab'可以佈局'attachment_layout' – yanzi1225627

還有另一種方式我的朋友，我在工作室使用設計選項卡今天的教訓。我拖着我的FAB錨定並找出這個代碼 -

<android.support.design.widget.FloatingActionButton 
     android:id="@+id/fab" 
     android:layout_height="wrap_content" 
     android:layout_width="wrap_content" 
     android:layout_margin="@dimen/activity_horizontal_margin" 
     android:src="@drawable/ic_add" 
     android:layout_gravity="center_vertical|center_horizontal" 
     app:layout_anchor="@+id/appBar" 
     app:layout_anchorGravity="bottom|right" />

請注意，這是工作完美，因爲我使用崩潰工具欄。我甚至嘗試設置不同的寬度和它的工作良好。

此外它還支持任何版本的支持庫。礦是25.0.0
