In my app i have each activity with drawer, but when i set drawer in my Preference activity, my activity working fine, but drawer not appear.
这是我的代码.
public class SettingActivity extends PreferenceActivity implements NavigationView.OnNavigationItemSelectedListener {
private AppCompatDelegate mDelegate;
private NavigationView mDrawer;
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mDrawerToggle;
@Override
public void onCreate(Bundle savedInstanceState) {
getDelegate().installViewFactory();
getDelegate().onCreate(savedInstanceState);
getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
super.onCreate(savedInstanceState);
if(savedInstanceState == null){
android.app.Fragment infoFragment = new MyPreferenceFragment();
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.add(R.id.fragment_container, infoFragment);
ft.commit();
}
}
public static class MyPreferenceFragment extends PreferenceFragment {
private AppSettings settings;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.pref);
Preference ringtonePrefs = findPreference("ringPref");
ringtonePrefs.setOnPreferenceChangeListener(new Preference.OnPreferenceChangeListener() {
@Override
public boolean onPreferenceChange(Preference preference, Object newValue) {
preference.setSummary(String.valueOf(newValue));
return true;
}
});
Preference mapTypePrefs = findPreference("mapPref");
mapTypePrefs.setOnPreferenceChangeListener(new Preference.OnPreferenceChangeListener() {
@Override
public boolean onPreferenceChange(Preference preference, Object newValue) {
preference.setSummary(String.valueOf(newValue));
return true;
}
});
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
settings = AppSettings.getSettings(getActivity());
Preference ringtonPrefs = findPreference("ringPref");
ringtonPrefs.setSummary(settings.getRingtone());
Preference maptypePrefs = findPreference("mapPref");
maptypePrefs.setSummary(settings.getMapType());
}
@Override
public void onPause() {
super.onPause();
getPreferenceScreen().getSharedPreferences().unregisterOnSharedPreferenceChangeListener(sharedPrefsChangeListener);
}
@Override
public void onResume() {
super.onResume();
getPreferenceScreen().getSharedPreferences().registerOnSharedPreferenceChangeListener(sharedPrefsChangeListener);
}
private final SharedPreferences.OnSharedPreferenceChangeListener sharedPrefsChangeListener = new SharedPreferences.OnSharedPreferenceChangeListener() {
@Override
public void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key) {
settings.load();
}
};
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == android.R.id.home) {
finish();
return true;
}
return false;

@Override

startActivity(intent);
return true;
}
if (item.getItemId() == R.id.navigation_item_3) {

mDrawerLayout.closeDrawer(GravityCompat.START);
Intent i = new Intent(this, SettingActivity.class);
startActivity(i);
return true;
}
mDrawerLayout.closeDrawers();
return true;
}
}
这是我的navigation_view.xml
this is my navigation_view.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/drawer_layoutS"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="@+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent"></FrameLayout>
<android.support.design.widget.NavigationView
android:id="@+id/mNavDrawerS"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:itemIconTint="@color/ColorAccent"
app:itemTextColor="@color/TextColor.DarkGray"
app:headerLayout="@layout/drawer_header"
app:menu="@menu/menu_drawer"/>
</android.support.v4.widget.DrawerLayout>
请告诉我我在这里缺少什么..或告诉我其他方法.
please tell me what i m missing here.. or tell me any other way to do it.
推荐答案
在活动的最低层级布局(默认情况下为content_main)中，添加一个名为fragment_container的FrameLayout.将宽度和高度设置为match_parent.这里的技巧是按照以下步骤创建您的片段:
In your activity's lowest hiearchical layout (content_main by default), add a FrameLayout named fragment_container. Set width and height to match_parent. Trick here is to create your fragment as this:
getFragmentManager()
.beginTransaction()
.replace(R.id.fragment_container, new MyFragment())
.commit();
因此，您基本上不需要在屏幕上添加片段，只需用片段替换预定义的布局即可.这样可以避免有关抽屉和工具栏的问题.如果没有，请告诉我，以便我进一步调查.
So you basically don't add a fragment to the screen, you just replace a pre-defined layout with a fragment. This prevents the issues regarding the drawer and toolbar. If not, let me know so I can investigate further.
