我需要有关偏好的帮助。我需要以编程方式创建它们。我有这个偏好屏幕：

<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" >
    <PreferenceCategory android:title="About" >
        <Preference android:title="Software Version" android:summary="1.3.554" android:key="software"/>
        <Preference android:title="User" android:summary="jnovkovic@itekako.com" android:key="email"/>
        <Preference android:title="Terms and conditions" />
    </PreferenceCategory>
    <PreferenceScreen android:key="log_out" android:layout="@layout/preference_log_out"/>


</PreferenceScreen>

我这样做了：

PreferenceScreen root = getPreferenceManager().createPreferenceScreen(this);
PreferenceCategory about = new PreferenceCategory(this);
        about.setTitle("About");
        root.addPreference(about);

        Preference software = new Preference(this);
        software.setTitle("Software Version");
        software.setKey("software");
        software.setSummary("1.3.554");
        about.addPreference(software);

        Preference user = new Preference(this);
        user.setTitle("User");
        user.setKey("user");
        user.setSummary(preferences.getString("user_email", ""));
        about.addPreference(user);

        Preference terms_and_conditions = new Preference(this);
        terms_and_conditions.setTitle("Terms and conditions");
        terms_and_conditions.setKey("terms_and_conditions");
        about.addPreference(terms_and_conditions);


        RelativeLayout layout = new RelativeLayout(this);
        layout.setId(1100);
        AbsListView.LayoutParams p = new AbsListView.LayoutParams(AbsListView.LayoutParams.MATCH_PARENT, AbsListView.LayoutParams.WRAP_CONTENT);
        layout.setLayoutParams(p);

        TextView log_out_text = new TextView(this);
        RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
        log_out_text.setTextSize(TypedValue.COMPLEX_UNIT_SP, 18);
        log_out_text.setTypeface(null, Typeface.BOLD);
        log_out_text.setGravity(Gravity.CENTER);
        log_out_text.setTextColor(Color.parseColor("#FFFFFF"));
        log_out_text.setBackgroundDrawable(log_out_drawable);
        log_out_text.setLayoutParams(params);
        layout.addView(log_out_text);

        Preference log_out = new Preference(this);
        log_out.setLayoutResource(1100);
        root.addPreference(log_out);

        setPreferenceScreen(root);

问题出在上面的第三行......有人可以帮助我吗？？？？

您正在尝试做的事情：以编程方式创建资源。你不能这样做。Android 资源是在编译过程中创建的。（基本上 xml 文件由 SDK 处理/编译，这就是创建资源的方式）。

您可以尝试的是：

  • 创建自定义public class MyPreference extends Preference
  • 覆盖onCreateView(ViewGroup parent)以返回您需要的布局。

并像这样使用这个类：

    Preference log_out = new MyPreference(this);
    root.addPreference(log_out);

这是一个简短的示例（假设您正在扩展 PreferenceActivity）：

  public void onCreate(Bundle savedInstanceState)
  {
  super.onCreate(savedInstanceState);
  PreferenceScreen screen = getPreferenceManager().createPreferenceScreen(this);

  PreferenceCategory category = new PreferenceCategory(this);
  category.setTitle("category name");

  screen.addPreference(category);

  CheckBoxPreference checkBoxPref = new CheckBoxPreference(this);
  checkBoxPref.setTitle("title");
  checkBoxPref.setSummary("summary");
  checkBoxPref.setChecked(true);

  category.addPreference(checkBoxPref);
  setPreferenceScreen(screen);
  }
