Android：无法解析简单的facebook onLoginListener

我正在使用简单的facebook库，我有以下代码：

import com.sromku.simple.fb.listeners.OnLoginListener;
import com.sromku.simple.fb.Permission;
import com.sromku.simple.fb.SimpleFacebook;
import com.sromku.simple.fb.SimpleFacebookConfiguration;



 public class MainActivity extends Activity {



private SimpleFacebook mSimpleFacebook;

private Button mButtonLogin;

@Override
public void onResume()
{
    super.onResume();
    mSimpleFacebook = SimpleFacebook.getInstance(this);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
    mSimpleFacebook.onActivityResult(this, requestCode, resultCode, data); 
    super.onActivityResult(requestCode, resultCode, data);
} 

// login listener
OnLoginListener onLoginListener = new SimpleFacebook.OnLoginListener()
{

    @Override
    public void onFail(String reason)
    {
        Log.w(TAG, reason);
    }

    @Override
    public void onException(Throwable throwable)
    {
        Log.e(TAG, "Bad thing happened", throwable);
    }

    @Override
    public void onThinking()
    {
        // show progress bar or something to the user while login is happening
        Log.i(TAG, "In progress");
    }

    @Override
    public void onLogin()
    {
        // change the state of the button or do whatever you want
        Log.i(TAG, "Logged in");
    }

    @Override
    public void onNotAcceptingPermissions()
    {
        Log.w(TAG, "User didn't accept read permissions");
    }

};

我在OnLoginListener中发现一个错误，它说“SimpleFacebook.OnLoginListener无法解决”，我导入了OnLoginListener，所以我不明白它为什么不工作？

为什么要编写

新的SimpleFacebook.OnLoginListener（）

？类

SimpleFacebook

不包含

OnLoginListener

您已经导入了

com.sromku.simple.fb.listeners.OnLoginListener

，这就是创建侦听器的原因：

OnLoginListener onLoginListener = new OnLoginListener()
{
 ...
}

你需要实现这个

 OnLoginListener onLoginListener = new OnLoginListener() {
    @Override
    public void onLogin() {
        // change the state of the button or do whatever you want
        Log.i("", "Logged in");
    }

    @Override
    public void onNotAcceptingPermissions(Permission.Type type) {
        // user didn't accept READ or WRITE permission
        Log.w("", String.format("You didn't accept %s permissions", type.name()));
    }

    @Override
    public void onException(Throwable throwable) {

    }

    @Override
    public void onFail(String reason) {

    }

    @Override
    public void onThinking() {

    }
