struts2單個文件上傳的兩種完成方法

平日來講Android手機沒有未接來電的監聽器，假如要完成對未接來電的處置，則須要本身編寫法式來完成。本文所述法式實例即為Android完成斷定手機未接來電及處置辦法。重要分為四個步調來停止：

1、編寫CallListener,處置手機狀況變革監聽,當狀況轉變時停止處置：

package rbase.app.smshelpmate.call.listener;
import java.text.MessageFormat;
import rbase.app.smshelpmate.Config;
import rbase.app.smshelpmate.R;
import rbase.app.smshelpmate.call.enums.CallStateEnum;
import rbase.app.smshelpmate.forward.ForwardManager;
import rbase.app.smshelpmate.forward.enums.ForwardType;
import rbase.app.smshelpmate.forward.vo.ForwardParam;
import android.content.Context;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.util.Log;

public class CallListener extends PhoneStateListener {
private static final String TAG = "sms";
private static int lastetState = TelephonyManager.CALL_STATE_IDLE; //最初的狀況
private Context context;
public CallListener(Context context) {
super();
this.context = context;
}
public void onCallStateChanged(int state, String incomingNumber) {
Log.v(TAG, "CallListener call state changed : " + incomingNumber);
String m = null;
// 假如以後狀況為余暇,前次狀況為響鈴中的話,則以為是未接來電
if(lastetState == TelephonyManager.CALL_STATE_RINGING
&& state == TelephonyManager.CALL_STATE_IDLE){
sendSmgWhenMissedCall(incomingNumber);
}
//最初轉變以後值
lastetState = state;
}
private void sendSmgWhenMissedCall(String incomingNumber) {
//未接來電處置(發短信,發email等)
}
}

2、編寫CallReceiver，注冊來電播送吸收器：

package rbase.app.smshelpmate.call.service;
import rbase.app.smshelpmate.Const;
import rbase.app.smshelpmate.call.listener.CallListener;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.util.Log;
public class CallReceiver extends BroadcastReceiver{
public void onReceive(Context context, Intent intent) {
Log.i("sms", "CallReceiver Start...");
TelephonyManager telephony = (TelephonyManager) context
.getSystemService(Context.TELEPHONY_SERVICE);
CallListener customPhoneListener = new CallListener(context);
telephony.listen(customPhoneListener,
PhoneStateListener.LISTEN_CALL_STATE);
Bundle bundle = intent.getExtras();
String phoneNr = bundle.getString("incoming_number");
Log.i("sms", "CallReceiver Phone Number : " + phoneNr);
}
}

3、在AndroidManifest.xml中的application節點下注冊德律風狀況轉變的播送吸收：

<manifest ...>
<application ...>
<receiver android:name=".call.service.CallReceiver">
<intent-filter android:priority="100">
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
</receiver>
</application>
</manifest>

4、在AndroidManifest.xml中添加讀取手機狀況的權限：

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

經由過程以上的步調,當手機有未接來電時 sendSmgWhenMissedCall 該辦法就會觸發,便可以停止響應的處置。
