关于PreferenceActivity的使用和一些问题的解决(自定义Title和取值)

标签：preferenceactivity   自定义title   

android的Setting往往用PreferenceActivity来写的

我们在建立layout文件:

<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<PreferenceCategory android:title="常规设置" android:key="set_local">
	<CheckBoxPreference
            android:key="new_message_notify"
            android:title="新消息通知"
            android:defaultValue="true"
            android:summary="收到新消息时是否需要通知" />

        <RingtonePreference
            android:layout="?android:attr/preferenceLayoutChild"
            android:dependency="new_message_notify"
            android:key="account_ringtone"
            android:title="铃声"
            android:ringtoneType="notification"
            android:defaultValue="content://settings/system/notification_sound" />

        <CheckBoxPreference
            android:layout="?android:attr/preferenceLayoutChild"
            android:dependency="new_message_notify"
            android:key="account_vibrate"
            android:defaultValue="false"
            android:title="振动"/>
</PreferenceCategory>
<PreferenceCategory android:title="个人设置" android:key="personal_local">
	<Preference android:key="clear_cache"
		android:summary="点击将清理应用程序的缓存" android:title="清除缓存" defaultValue="false">
	</Preference>
	<CheckBoxPreference android:key="save_setting"
		android:summary="下次开启记住个人设置" android:title="保存个人设置" android:defaultValue="true">
	</CheckBoxPreference>
	
	<EditTextPreference
	    android:key="edit_text"
	    android:title="Edit" android:summary="EditTextPreference"
	></EditTextPreference>
	
	<SwitchPreference
	    android:key="switch" android:summary="SwitchPreference"
	></SwitchPreference>
	
	<ListPreference
	    android:key="list" android:summary="ListPreference" android:entries="@array/entry" android:entryValues="@array/entry_value" android:title="ListTitle"
	></ListPreference>
	
	<MultiSelectListPreference 
	    android:summary="MultiSelectListPreference" android:key="mutiSelect" android:entries="@array/entry" android:entryValues="@array/entry_value" android:title="mutiTitle"
	    />
</PreferenceCategory>
</PreferenceScreen>

public class Settings extends PreferenceActivity {


	@Override
	protected void onCreate(Bundle savedInstanceState) {
		//这个是给Settings加自定义Title
		final boolean isCustom = requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
		super.onCreate(savedInstanceState);
		if(isCustom){
			getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.title_list);
		}
		TextView title_text = (TextView)findViewById(R.id.title_text);
		title_text.setText("Settings");
		Button back = (Button)findViewById(R.id.back);
		back.setVisibility(View.VISIBLE);
		back.setOnClickListener(new View.OnClickListener() {
			
			@Override
			public void onClick(View v) {
				finish();
				
			}
		});
		
		addPreferencesFromResource(R.xml.seting_preferences);

	}

}

    <style name="AppTheme" parent="AppBaseTheme">  
  
        <!-- All customizations that are NOT specific to a particular API-level can go here. -->  
        <!-- 避免重复设置标题 -->  
        <item name="android:windowActionBar">false</item>  
        <!-- 设置标题栏宽度 -->  
        <item name="android:windowTitleSize">60dp</item>   //titlebar的高度
        <!-- <item name="android:windowTitleBackgroundStyle">@style/CustomWindowTitleBackground</item> -->  
    </style>

SharedPreferences shp = PreferenceManager.getDefaultSharedPreferences(this);
		String s = shp.getString("list", null);  //这个是取ListPreference
		TextView listData = (TextView)findViewById(R.id.listData);
		listData.setText(s);
		
		HashSet set = (HashSet) shp.getStringSet("mutiSelect", null); //这个是取MultiSelectListPreference的值
		Iterator<String> it = set.iterator();
		String content = "";
		while(it.hasNext()) {
			content += it.next()+",";
		}
		TextView muti_select_data = (TextView)findViewById(R.id.muti_select_data);
		muti_select_data.setText(content);
