安卓.content.res.Resources$NotFoundException : Resource ID #0x0

Question

我正在按照步骤从 Linkedin 获取数据。但是我收到错误:

04-25 15:19:09.516 3078-3078/app.plusconnect.com.linkedindummy E/AndroidRuntime:致命异常:main android.content.res.Resources$NotFoundException: 资源 ID #0x0

public class MainActivity extends ActionBarActivity {

//declaration
SocialAuthAdapter adapter;
Button linkedin_button;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    adapter = new SocialAuthAdapter(new ResponseListener());

    linkedin_button = (Button)findViewById(R.id.SubmitButton);
    linkedin_button.setBackgroundResource(R.mipmap.linkedin);

    linkedin_button.setOnClickListener(new View.OnClickListener()
    {
        public void onClick(View v)
        {
            adapter.authorize(MainActivity.this, Provider.LINKEDIN);
        }
    });

}

public class ResponseListener implements DialogListener {

    @Override
    public void onComplete(Bundle bundle) {

        adapter.getUserProfileAsync(new ProfileDataListener());
    }

    @Override
    public void onError(SocialAuthError socialAuthError) {
    }

    @Override
    public void onCancel() {
    }

    @Override
    public void onBack() {
    }
}

public class ProfileDataListener implements SocialAuthListener<Profile> {

    @Override
    public void onExecute(String s, Profile profile) {
        Log.d("Custom-UI", "Receiving Data");
        Profile profileMap = profile;
        Log.d("Custom-UI",  "Validate ID         = " + profileMap.getValidatedId());
        Log.d("Custom-UI",  "First Name          = " + profileMap.getFirstName());
        Log.d("Custom-UI",  "Last Name           = " + profileMap.getLastName());
        Log.d("Custom-UI",  "Email               = " + profileMap.getEmail());
        Log.d("Custom-UI",  "Country                  = " + profileMap.getCountry());
        Log.d("Custom-UI",  "Language                 = " + profileMap.getLanguage());
        Log.d("Custom-UI",  "Location                 = " + profileMap.getLocation());
        Log.d("Custom-UI", "Profile Image URL  = " + profileMap.getProfileImageURL());

    }

    @Override
    public void onError(SocialAuthError socialAuthError) {
    }
}

}

这是布局文件

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"

    android:padding="20dp"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true"
    android:text="Test Connect application like to fetch Profile details from LinkedIn Account."/>

<!-- Submit button -->
<Button
    android:id="@+id/SubmitButton"
    android:layout_width="200dp"
    android:layout_height="40dp"
    android:layout_marginBottom="20dp"

    android:text="Fetch from LinkedIn"
    android:textColor="@android:color/white"

    android:layout_centerHorizontal="true"/>

问题出在哪里？有人可以帮忙吗？

Answer 1

SocialAuth 需要在 drawable 文件夹中为您要集成的每个服务提供一个图像。

您可能没有这些图片，SocialAuth 在尝试加载图片时崩溃。要解决此问题，只需将您要使用的每项服务的图像(例如 linkedin.png、twitter.png、facebook.png)放入 drawable 文件夹。
