java - 如何更改 PreferenceCategory/PreferenceScreen 的文本颜色

Question

这是:

preferences.xml

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

    <PreferenceCategory
        android:key="@string/pref_basicsettings_key"
        android:title="@string/pref_basicsettings_title" >
        <CheckBoxPreference
            android:defaultValue="@string/pref_test1_default"
            android:key="@string/pref_test1_key"
            android:summary="@string/pref_test1_dlg"
            android:title="@string/pref_test1_title" />
        <CheckBoxPreference
            android:defaultValue="@string/pref_test2_default"
            android:key="@string/pref_test2_key"
            android:summary="@string/pref_test2_dlg"
            android:title="@string/pref_test2_title" />
    </PreferenceCategory>
</PreferenceScreen>

BasicSettingsActivity.java

public class BasicSettingsActivity extends PreferenceActivity {

    public static final String TAG = BasicSettingsActivity.class
            .getSimpleName();

    /** Called when the activity is first created. */
    @SuppressWarnings("deprecation")
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        prefs.registerOnSharedPreferenceChangeListener(mSharedPreferenceListener);

        // add preference resource
        addPreferencesFromResource(com.testapp.R.xml.basic_settings);
    }
}

如何更改 PreferenceCategory 中的文本颜色？

Answer 1

我添加了一个新样式:

<style name="PreferenceScreen" parent="Theme.AppCompat">
    <item name="android:textColor">#ffffff</item>
    <item name="android:textColorPrimary">#ffffff</item>
    <item name="colorPrimary">#ff0000</item>
    <item name="colorPrimaryDark">#ff0000</item>
    <item name="colorAccent">#ff0000</item>
    <item name="android:background">#CCCCCC</item>
</style>

并将其包含在 Activity 中:

<activity android:name="com.smartipcamera.owlcam.ui.BasicSettingsActivity"
    android:theme="@style/PreferenceScreen" >
</activity>
