设置界面设计

如何获得用户名的值呢：

// 获得配置参数：用户名
  final String userName = PreferenceManager.getDefaultSharedPreferences(
    this).getString("user_name", null);

 AndoridManifest.xml

<activity android:name=".view.setting.SetView" >
            <intent-filter >
                <action android:name="android.intent.action.VIEW" />

                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>

 

通过菜单调用：

// 菜单-----------------------------------------------------------

	public boolean onCreateOptionsMenu(Menu menu) {
		menu.add(0, 1, 0, "设置").setIcon(android.R.drawable.ic_menu_preferences);
		return super.onCreateOptionsMenu(menu);
	}

	public boolean onOptionsItemSelected(MenuItem item) {
		switch (item.getItemId()) {
		// 设置
		case 1:
			SetView.launch(this);
			break;

		default:

		}
		return super.onOptionsItemSelected(item);
	}

 设置页面：

package com.lilin.mediaplay.view.setting;

import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.preference.PreferenceActivity;

import com.lilin.mediaplay.R;

/**
 * 设置界面
 * 
 * @author lilin
 * @date 2011-12-13 上午12:06:03
 * @ClassName: SettingsActivity
 */
public class SetView extends PreferenceActivity {

	public static void launch(Context c) {
		Intent intent = new Intent(c, SetView.class);
		c.startActivity(intent);
	}

	public void onCreate(Bundle savedInstanceState) {
		// requestWindowFeature(Window.FEATURE_NO_TITLE);
		super.onCreate(savedInstanceState);
		addPreferencesFromResource(R.xml.preferences);
		setContentView(R.layout.setview);
		setTitle("系统设置");
	}

}

 布局文件：

一个是preferences

<?xml version="1.0" encoding="utf-8"?>
	<!-- 系统设置界面 -->
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">

	<PreferenceCategory android:title="常用设置"
		android:summary="Application settings">
		<!-- 编辑框 -->
		<EditTextPreference 
		    android:key="user_name"
			android:defaultValue="@null" 
			android:title="用户名" 
			android:summary="请设置您的个人用户名" />
		<ListPreference 
			android:key="download_format"
			android:title="下载格式" 
			android:summary="请设置音频下载格式" 
			android:entries="@array/audio_format"
			android:entryValues="@array/audio_format_values" />
			
		<CheckBoxPreference 
			android:key="wifi_only"
			android:defaultValue="false" 
			android:title="WIFI设置" 
			android:summary="只有WIFI模式下才联网" />
		<CheckBoxPreference 
			android:key="roaming_protection"
			android:defaultValue="true" 
			android:title="Roaming Protection"
			android:summary="Disable listening abroad" />

	</PreferenceCategory>

	<PreferenceCategory android:title="其他设置"
		android:summary="Interaction with outside applications">

		<CheckBoxPreference android:key="lastfm_scrobble"
