我目前正在将我的应用转换为Fragments，并遇到了许多问题。我希望能够在你的帮助下解决所有这些问题，并在我解决转换的某个部分后编辑我的帖子。
第一个问题： AlertDialogs。当用户单击某个按钮（稍后可能是ListView项）时，会向他们显示AlertDialog以选择他们想要查看的帐户。我这是为Facebook和Twitter做的。但是，双重构造让我感到困惑，而ListDialog似乎以不同的方式加载其内容。
所以，我的活动代码：
package bas.sie.Antonius;
import android.app.AlertDialog;
import android.app.Dialog;
import android.content.DialogInterface;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.support.v4.app.DialogFragment;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import com.actionbarsherlock.app.SherlockFragment;
public class External extends SherlockFragment implements OnClickListener {
Button mBtnOuderPortaal;
Button mBtnTeletop;
Button mBtnWebmail;
Button mBtnInfobord;
Button mBtnTwitter;
Button mBtnFacebook;
Button mBtnYouTube;
String URLhome;
String Title;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mBtnOuderPortaal = (Button) getActivity().findViewById(
R.id.btnOuderPortaal);
mBtnOuderPortaal.setOnClickListener(this);
mBtnTeletop = (Button) getActivity().findViewById(R.id.btnTeletop);
mBtnTeletop.setOnClickListener(this);
mBtnWebmail = (Button) getActivity().findViewById(R.id.btnWebmail);
mBtnWebmail.setOnClickListener(this);
mBtnInfobord = (Button) getActivity().findViewById(R.id.btnInfobord);
mBtnInfobord.setOnClickListener(this);
mBtnTwitter = (Button) getActivity().findViewById(R.id.btnTwitter);
mBtnTwitter.setOnClickListener(this);
mBtnFacebook = (Button) getActivity().findViewById(R.id.btnFacebook);
mBtnFacebook.setOnClickListener(this);
mBtnYouTube = (Button) getActivity().findViewById(R.id.btnYouTube);
mBtnYouTube.setOnClickListener(this);
}

错误发生在：
- .create();在第一个对话框中显示
Syntax error on token "create", Identifier expected after this token
Syntax error, insert ";" to complete MethodDeclaration
Syntax error, insert ";" to complete ReturnStatement
Syntax error, insert ")" to complete MethodInvocation
Syntax error, insert "}" to complete ClassBody
MyAlertDialogFragment中的 - showDialog();，表示MyAlertDialogFragment无法解析。
- 初始化第二个对话框：
Syntax error on token ".", delete this token
The method setItems(CharSequence[], new DialogInterface.OnClickListener(){}) is undefined for the type External.MyFBAlertDialogFragment.MyAlertDialogFragment
Type mismatch: cannot convert from AlertDialog.Builder to Dialog
然后在builder上创建第二个对话框：builder cannot be resolved。这个显然是合法的，但我没有解决方案。
它还抱怨资源目录名无效。
我刚刚解决的最后一个问题：）。
我正在使用ABS，但这是ABS中的一个标签。这意味着它需要是一个片段，但不显示ActionBar。
答案 0 :(得分：0)
您有多个语法错误。那是什么
此令牌后预期的标识符
装置
你应该将你的片段移动到那些更容易维护的类文件。
我可以发现一个错误我认为但是在浏览器中很难：
default:
return;
}
}
getDialog.create();
)
}
应该是：
default:
return;
}
}
getDialog.create();
}
);
}
（是的，一个分号丢失）
答案 1 :(得分：0)
您发布了活动的代码，但您的约定是继承自 SherlockFragment 而不是 SherlockFragmentActivity 。
您可以查看Fragment vs FragmentActivity。
答案 2 :(得分：0)
感谢大家尝试提供帮助，但它已经解决了一段时间。
但是，这里发布的代码很多，所以如果有人想知道：给我发消息，我会尽力帮助你！
