java首选项片段布局上的片段重叠
我已经能够使用PreferenceFragment实现一个设置页面。在我导航到另一个页面之前,它显示得很好。设置页面仍然显示在其他页面的顶部,我不知道如何完全替换它
这张图片就是我的意思的一个例子。我已经通过导航抽屉从设置页面导航到主页。我想我在replace()
方法中遗漏了一些东西,但我不知道是什么
帐户设置。java
public class AccountSettings extends PreferenceFragment {
Activity mActivity;
private static final String ARG_SECTION_NUMBER = "section_number";
public static AccountSettings newInstance(int sectionNumber) {
AccountSettings fragment = new AccountSettings();
Bundle args = new Bundle();
args.putInt(ARG_SECTION_NUMBER, sectionNumber);
fragment.setArguments(args);
return fragment;
}
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.settings);
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
getView().setBackgroundColor(Color.WHITE);
getView().setClickable(true);
}
@Override
public void onAttach(Activity activity) {
super.onAttach(activity);
mActivity = activity;
}
@Override
public void onDestroy() {
super.onDestroy();
}
@Override
public void onDetach() {
super.onDetach();
}
public void restoreActionBar() {
ActionBar actionBar = ((AppCompatActivity)getActivity()).getSupportActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_STANDARD);
actionBar.setDisplayShowTitleEnabled(true);
actionBar.setTitle("Account Settings");
}
public AccountSettings() {
}
}
主页。java(导航抽屉)
public void onNavigationDrawerItemSelected(int position) {
// update the main content by replacing fragments
FragmentManager fragmentManager = getSupportFragmentManager();
if (position == 0) {
fragmentManager.beginTransaction()
.replace(R.id.container, PlaceholderFragment.newInstance(1))
.commit();
} else if (position == 1) {
fragmentManager.beginTransaction()
.replace(R.id.container, Search.newInstance(2))
.commit();
}
else if (position == 2) {
fragmentManager.beginTransaction()
.replace(R.id.container, Favourites.newInstance(3))
.commit();
}
else if (position == 3) {
fragmentManager.beginTransaction()
.replace(R.id.container, History.newInstance(4))
.commit();
}
else if (position == 4) {
getFragmentManager().beginTransaction()
.replace(R.id.container, AccountSettings.newInstance(5))
.commit();
}
}
设置。xml
<PreferenceScreen xmlns:安卓="http://schemas.安卓.com/apk/res/安卓"

活动主页。xml

在fragments'
oncreateView
方法中添加这一行在膨胀碎片的视图之前。这对我有帮助
