SwitchPreference使用

1，布局

<?xml version="1.0" encoding="utf-8"?> <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"> <PreferenceCategory android:summary="选择想要切换的皮肤" android:title="皮肤切换"> <SwitchPreference android:key="BuildInNightMode" android:summary="应用内换肤" android:title="夜间模式" /> <SwitchPreference android:key="AssetsNightMode" android:summary="插件式换肤" android:title="夜间模式" /> <SwitchPreference android:key="SDCardNightMode" android:summary="指定sdcard路径" android:title="夜间模式" /> </PreferenceCategory> </PreferenceScreen>

2，java

public class SettingsFragment extends PreferenceFragment { public static final String BUILD_IN_NIGHT_MODE_KEY = "BuildInNightMode"; public static final String ASSETS_NIGHT_MODE_KEY = "AssetsNightMode"; public static final String SDCARD_NIGHT_MODE_KEY = "SDCardNightMode"; private SwitchPreference mBuildInNightModePreference; private SwitchPreference mAssetsNightModePreference; private SwitchPreference mSDCardNightModePreference; @Override public void onCreate(@Nullable Bundle savedInstanceState) { super.onCreate(savedInstanceState); addPreferencesFromResource(R.xml.setting_preferences); mBuildInNightModePreference = (SwitchPreference) findPreference(BUILD_IN_NIGHT_MODE_KEY); mBuildInNightModePreference.setOnPreferenceChangeListener(new Preference.OnPreferenceChangeListener() { @Override public boolean onPreferenceChange(Preference preference, Object newValue) { mAssetsNightModePreference.setChecked(false); mSDCardNightModePreference.setChecked(false); boolean boolValue = (boolean) newValue; if (boolValue) { SkinCompatManager.getInstance().loadSkin("night", null, SkinCompatManager.SKIN_LOADER_STRATEGY_BUILD_IN); } else { SkinCompatManager.getInstance().restoreDefaultTheme(); } return true; } }); mAssetsNightModePreference = (SwitchPreference) findPreference(ASSETS_NIGHT_MODE_KEY); mAssetsNightModePreference.setOnPreferenceChangeListener(new Preference.OnPreferenceChangeListener() { @Override public boolean onPreferenceChange(Preference preference, Object newValue) { mBuildInNightModePreference.setChecked(false); mSDCardNightModePreference.setChecked(false); boolean boolValue = (boolean) newValue; if (boolValue) { SkinCompatManager.getInstance().loadSkin("night.skin", null, SkinCompatManager.SKIN_LOADER_STRATEGY_ASSETS); } else { SkinCompatManager.getInstance().restoreDefaultTheme(); } return true; } }); mSDCardNightModePreference = (SwitchPreference) findPreference(SDCARD_NIGHT_MODE_KEY); mSDCardNightModePreference.setOnPreferenceChangeListener(new Preference.OnPreferenceChangeListener() { @Override public boolean onPreferenceChange(Preference preference, Object newValue) { mBuildInNightModePreference.setChecked(false); mAssetsNightModePreference.setChecked(false); boolean boolValue = (boolean) newValue; if (boolValue) { SkinCompatManager.getInstance().loadSkin("night.skin", null, CustomSDCardLoader.SKIN_LOADER_STRATEGY_SDCARD); } else { SkinCompatManager.getInstance().restoreDefaultTheme(); } return true; } }); } }
