我正在创建一个应用程序，我在其中使用带有导航抽屉的首选项片段我的问题是我创建了导航抽屉，并且我在其中添加了一些菜单项，我想在其中加载首选项片段作为应用程序加载时的第一个元素。它就像我不显示的那样。当我更改选项时，即当我更改抽屉菜单选项（如第二个元素）时，抽屉菜单第一个视图中的第二个元素不会替换，它与第一个元素重叠
我的导航抽屉xml如下
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.koteswara.wise.NavigationDrawerMainActivity" >
<FrameLayout
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<LinearLayout
android:id="@+id/drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:orientation="vertical"
android:layout_gravity="start" >
<ListView
android:id="@+id/drawer_list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/white"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"
android:dividerHeight="0dp"
tools:context="com.koteswara.wise.NavigationDrawerFragment" />
</LinearLayout>
</android.support.v4.widget.DrawerLayout>
我的偏好片段是这样的
public class AutoAnswerPreferenceActivity extends PreferenceFragment implements OnSharedPreferenceChangeListener {
private AutoAnswerNotifier mNotifier;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.preference);
mNotifier = new AutoAnswerNotifier(getActivity());
mNotifier.updateNotification();
SharedPreferences sharedPreferences = getPreferenceManager().getSharedPreferences();
sharedPreferences.registerOnSharedPreferenceChangeListener(this);
}
@Override
public void onDestroy() {
getPreferenceManager().getSharedPreferences().unregisterOnSharedPreferenceChangeListener(this);
super.onDestroy();
}
@Override
public void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key) {
if (key.equals("enabled")) {
mNotifier.updateNotification();
}
}
}
我正在添加以加载 PreferenceFragment 的片段类是
public class AutoAnswarFragment extends Fragment {
@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
getActivity().getFragmentManager().beginTransaction().replace(R.id.container, new AutoAnswerPreferenceActivity()) .commit();
}
显示片段方法所在的导航抽屉类
protected void showFragment(int position) {
// TODO Auto-generated method stub
Fragment fragment = null;
switch (position) {
case 0:
fragment = new AutoAnswarFragment();
break;
case 1:
fragment = new Tab2();
break;
case 2:
// fragment = new BhajanaFragment();
break;
}
if (fragment != null) {
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.container, fragment).commit();
// update selected item and title, then close the drawer
// mDrawerList.setItemChecked(position, true);
// mDrawerList.setSelection(position);
mTitle = mDrawer_title[position];
// mDrawerLayout.closeDrawer(mDrawerList);
} else {
// error in creating fragment
// Log.e("MainActivity", "Error in creating fragment");
}
}
}
如果我将调用除下面的偏好片段以外的片段，它会起作用，请帮助我
public class Tab1 extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
View v =inflater.inflate(R.layout.tab_1,container,false);
return v;
}
}
我正在努力清除它的解决方案，请任何人解决它，请告诉我解决方案。我将非常感谢，请帮助我
