我在项目中设置了(PreferenceScreen)的问题。
如何更改(标题)和(摘要)文本的颜色。
用不同的方法尝试几个小时后没有运气,我一定是做错了
settings fragment.Java
public class SettingsFragment extends Fragment {
public SettingsFragment() {
// Required empty public constructor
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
getActivity().getFragmentManager().beginTransaction()
.replace(R.id.flContent, new SettingsPreference())
.commit();
}
public static class SettingsPreference extends PreferenceFragment {
public SettingsPreference() {
// Required empty public constructor
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Load the preferences from an XML resource
addPreferencesFromResource(R.xml.settings);
}
}
}

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="match_parent"
android:background="?attr/app_background"
android:clickable="true"

的settings.xml
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<PreferenceCategory
android:key="pref_key_storage_settings"
android:title="First">
<CheckBoxPreference
android:defaultValue="false"
android:key="pref_key_auto_delete"
android:summary="Sub 1 summary"
android:title="Sub 1" />
<Preference
android:dependency="pref_key_auto_delete"
android:key="pref_key_sms_delete_limit"
android:summary="Sub 2 summary"
android:title="Sub 2" />
<Preference
android:dependency="pref_key_auto_delete"
android:key="pref_key_mms_delete_limit"
android:summary="Sub 3 summary"
android:title="Sub 3" />
</PreferenceCategory>
</PreferenceScreen>
我之前通过使用自定义首选项主题并在自定义主题中设置android:textColor
(标题颜色)和android:textColorSecondary
(摘要颜色)来完成此操作。例如,黑色标题和白色摘要:
<style name="AppTheme" parent="Theme.AppCompat.NoActionBar">
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
<item name="preferenceTheme">@style/AppPreferenceTheme</item>
</style>
<!-- Custom Preference Theme -->
<style name="AppPreferenceTheme"
parent="@style/PreferenceThemeOverlay.v14.Material">
<item name="android:textColor">@android:color/black</item>
<item name="android:textColorSecondary">@android:color/white</item>
</style>
您可以将“AppPreferenceTheme”重命名为您喜欢的任何名称。
