java - Android xml和Java : Get text from Edit Text,找不到符号错误

Question

我正在尝试从我的 Android 应用程序的 EditText 元素中获取 getText() 。这是我用来声明编辑文本的 Java I 代码:

public class LogFragment extends Fragment {

    private AlertDialog mDialog;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View logView = inflater.inflate(R.layout.log_form, container, false);
        final EditText raceName = (EditText) findViewById(R.id.EditTextName);
        // Handle buttons here...
        View logButton = logView.findViewById(R.id.ButtonLogRace);
        logButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
                builder.setMessage(R.string.logged_text);
                builder.setCancelable(false);
                builder.setPositiveButton(R.string.ok_label,
                        new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialogInterface, int i) {
                                // develop georeferencing, shared preferences saving, automatic calculations and a results window

                            }
                        });
                mDialog = builder.show();
            }
        });
        return logView;
}

这是使用 xml 构建的 EditText:

<EditText
android:id="@+id/EditTextName"
android:layout_height="wrap_content"
android:hint="@string/racename"
android:inputType="textPersonName"
android:layout_width="fill_parent"
android:textSize="8pt">
</EditText>

为什么我会收到此错误:

error: cannot find symbol method findViewById(int)

Answer 1

试试这个

    final EditText raceName = (EditText) logView .findViewById(R.id.EditTextName);
