Question

我尝试将PreferenceFragmentCompat加载到FrameLayout。但是当我尝试用SettingsFragment替换片段时，应用程序就会死掉。我从Logcat得到的一切都是：＆＃34;发送信号。 PID：16947 SIG：9＆＃34;

如何将SettingsFragment放置到FrameLayout？

public class SettingsFragment extends PreferenceFragmentCompat {

    @Override
    public void onCreatePreferences(Bundle bundle, String s) {
        setPreferencesFromResource(R.xml.fragment_settings, s);
    }
}

fragment_settings.xml：

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_height="match_parent"
    android:layout_width="match_parent">

    <PreferenceCategory
        android:title="HTTP Requests">

        <PreferenceCategory
            android:title="Zustand abfragen">

            <EditTextPreference
                android:key="state_request_url"
                android:title="URL"
                android:summary="Test"
                android:dialogTitle="Test" />

        </PreferenceCategory>

        <PreferenceCategory
            android:title="Zustand ändern">

            <EditTextPreference
                android:key="state_change_url"
                android:title="URL"
                android:summary="Test"
                android:dialogTitle="Test" />

        </PreferenceCategory>

    </PreferenceCategory>

</PreferenceScreen>

我如何加载片段：

FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();

transaction.replace(R.id.fragment_container, new SettingsFragment());
transaction.addToBackStack(null);

transaction.commit();
