继续N天前的项目
开启服务监听手机来电,查询数据库,显示归属地
详细内容可以参考这篇博文:http://www.cnblogs.com/taoshihan/p/5331232.html
AddressService.java
package com.qingguow.mobilesafe.service; import com.qingguow.mobilesafe.utils.NumberQueryAddressUtil; import android.app.Service; import android.content.Intent; import android.os.IBinder; import android.telephony.PhoneStateListener; import android.telephony.TelephonyManager; import android.widget.Toast; /** * 来电显示 * * @author taoshihan * */ public class AddressService extends Service { private TelephonyManager tm; private MyPhoneStateListener phoneStateListener; @Override public IBinder onBind(Intent arg0) { // TODO Auto-generated method stub return null; } /** * 服务创建 */ @Override public void onCreate() { super.onCreate(); tm = (TelephonyManager) getSystemService(TELEPHONY_SERVICE); phoneStateListener = new MyPhoneStateListener(); tm.listen(phoneStateListener, PhoneStateListener.LISTEN_CALL_STATE); } private class MyPhoneStateListener extends PhoneStateListener { @Override public void onCallStateChanged(int state, String incomingNumber) { super.onCallStateChanged(state, incomingNumber); switch (state) { case TelephonyManager.CALL_STATE_RINGING: String info = NumberQueryAddressUtil .queryAddress(incomingNumber); Toast.makeText(getApplicationContext(), info, 1).show(); break; default: break; } } } /** * 服务销毁 */ @Override public void onDestroy() { // TODO Auto-generated method stub super.onDestroy(); //取消监听 tm.listen(phoneStateListener, PhoneStateListener.LISTEN_NONE); phoneStateListener=null; } }
设置中心,配置是否开启来电归属地显示
直接使用我们之前定义好的组合控件
<com.qingguow.mobilesafe.ui.SettingItemView tsh:title="设置显示号码归属地" tsh:desc_on="设置显示号码归属地已开启" tsh:desc_off="设置显示号码归属地已关闭" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/siv_show_address"> </com.qingguow.mobilesafe.ui.SettingItemView>
获取到SettingItemView对象,我们自定义的控件,设置状态
调用SettingItemView对象的setOnClickListener()方法,设置点击事件,重写onClick方法
调用SettingItemView对象的isChecked()方法,得到当前是否选中
判断状态,调用SettingItemView对象的setChecked()方法,设置状态,参数:布尔值
调用startService()方法,开启监听手机状态的服务,参数:Intent对象,
调用stopService()方法,关闭服务
判断当前服务是否开启,设置控件的默认选中状态
新建一个工具类ServicesUtils.java
定义一个静态方法isServiceRunning(),传入参数:Context上下文,String服务名
调用Context对象的getSystemService()方法,获取ActivityManager对象,参数:Context.ACTIVITY_SERVICE
调用ActivityManager对象的getRunningServices()方法,得到运行的服务List集合,参数:int最大值
for循环List集合,每条是个RunningServiceInfo对象
调用RunningServiceInfo.servie.getClassName(),获取到String服务类名,判断一下如果相等返回true
SettingActivity.java

ServicesUtils.java
