从PreferenceActivity访问主UI布局组件

时间：2013-11-18 20:04:45

标签： android preferences

在我的PreferenceActivity中，我有：

public class SettingsActivity extends PreferenceActivity implements
    SharedPreferences.OnSharedPreferenceChangeListener {
SharedPreferences sp;
private final String TAG = getClass().getSimpleName();
private SimpleFacebook mSimpleFacebook;
ProgressDialog  progressBar;
Context ctx;
RelativeLayout connection;
SlidingUpPanelLayout slider;


protected void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    ctx = this;
    addPreferencesFromResource(R.xml.preferences);
    Preference button = (Preference)findPreference("logoutButton");

    Context context = getBaseContext();
    LayoutInflater lif = (LayoutInflater) getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    connection = (RelativeLayout) lif.inflate(R.id.conexion, null);

    }
}

我需要夸大布局的参考，以便我可以消失一个元素。 当我选择整个布局（R.layout.activity_main）时，我收到错误：

android.view.InflateException: Binary XML file line #12: Error inflating class fragment

（在activity_main中，我有一个显示地图的片段）

当我尝试仅对布局（连接）的一个组件进行充气时，我收到错误：

 android.content.res.Resources$NotFoundException: Resource ID #0x7f060007 type #0x12 is not valid

我该怎么办？

编辑： 案例1：

RelativeLayout layout = (RelativeLayout)lif.inflate(R.layout.activity_main, null);

我需要夸大布局的引用，这样我才能消失元素。

您不能以这种方式隐藏主要活动中的元素。您的设置活动应该更改设置，就是这样。这取决于处理自己观点的主要活动。在onResume()中，您可以检查设置并在适当的时候隐藏它。

答案 1 :(得分：1)

首先，您的布局和错误java.lang.ClassNotFoundException: android.view.fragment表示您的活动必须从FragmentActivity延伸，否则您无法通过<fragment>来填充布局
