我可以在 Android Studio 中看到 LoginButton 类，所以它有点工作

I can see the LoginButton class in Android Studio, so it kind of works

这是我的 build.gradle 依赖项

Here's my build.gradle dependencies

dependencies {

aspects 'org.robobinding:robobinding:0.8.9'
compile 'org.springframework.android:spring-android-rest-template:2.0.0.M1'
compile 'com.android.support:appcompat-v7:21.0.3'
compile 'com.android.support:support-v4:21.0.3'
compile 'com.android.support:support-v13:21.0.3'

compile 'com.android.support:recyclerview-v7:21.0.3'
compile 'com.fasterxml.jackson.core:jackson-databind:2.3.2'
compile 'com.jakewharton:butterknife:6.1.0'
compile 'com.facebook.android:facebook-android-sdk:4.0.1'
compile 'me.alexrs:recyclerview-renderers:1.0.3'
compile 'com.google.android.gms:play-services:6.5.87'
}

这是我的布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:facebook="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center_horizontal"
    android:orientation="vertical"
    android:padding="20dp" >

    <com.facebook.widget.LoginButton
        android:id="@+id/connectWithFbButton"
        style="@style/com_facebook_loginview_default_style"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:layout_gravity="center_horizontal"
        android:text="  connect_with_facebook"/>
</LinearLayout>

以及我活动的相关部分

@Override
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        FacebookSdk.sdkInitialize(getApplicationContext());


        callbackManager = CallbackManager.Factory.create();


        setContentView(R.layout.activity_main);

        // Set a Toolbar to replace the ActionBar.
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        // Find our drawer view
        dlDrawer = (FragmentNavigationDrawer) findViewById(R.id.drawer_layout);
        // Setup drawer view
        dlDrawer.setupDrawerConfiguration((ListView) findViewById(R.id.lvDrawer), toolbar,
                R.layout.drawer_nav_item, R.id.flContent);
        // Add nav items
        dlDrawer.addNavItem("Home", "First Fragment", ClassifiedsFragment.class);
        dlDrawer.addNavItem("Favourites", "Favourites", ClassifiedsFragment.class);
        dlDrawer.addNavItem("My Items", "Items", ClassifiedsFragment.class);
        dlDrawer.addNavItem("Settings", "Settings", ClassifiedsFragment.class);


        //dlDrawer.addNavItem("Second", "Second Fragment", SecondFragment.class);
        //dlDrawer.addNavItem("Third", "Third Fragment", ThirdFragment.class);
        // Select default
        if (savedInstanceState == null) {
            dlDrawer.selectDrawerItem(0);
        }
    }

推荐答案

在 facebook sdk 4.0.1 中，LoginButton 类不在 com.facebook.widget 包内.它位于 com.facebook.login.widget 包内.所以你的 xml 声明应该是这样的:

In facebook sdk 4.0.1, LoginButton class is not inside com.facebook.widget package. It is inside com.facebook.login.widget package. So your xml declaration should look like this:

  <com.facebook.login.widget.LoginButton
    android:id="@+id/connectWithFbButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerInParent="true"
    android:layout_gravity="center_horizontal"
    android:text="  connect_with_facebook" />
