android sim卡插拔广播,Android监听SIM卡插拔的方式

监听SIM卡是否可用

import android.app.Service;

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

import android.telephony.TelephonyManager;

* 监听sim状态改变的广播，返回sim卡的状态，有效或者无效。

* 双卡中只要有一张卡的状态有效即返回状态为有效，两张卡都无效则返回无效。

public class SimStateReceive extends BroadcastReceiver {

private final static String ACTION_SIM_STATE_CHANGED = "android.intent.action.SIM_STATE_CHANGED";

private final static int SIM_VALID = 0;

private final static int SIM_INVALID = 1;

private int simState = SIM_INVALID;

public int getSimState() {

return simState;

}

@Override

public void onReceive(Context context, Intent intent) {

System.out.println("sim state changed");

if (intent.getAction().equals(ACTION_SIM_STATE_CHANGED)) {

TelephonyManager tm = (TelephonyManager)context.getSystemService(Service.TELEPHONY_SERVICE);

int state = tm.getSimState();

switch (state) {

case TelephonyManager.SIM_STATE_READY :

simState = SIM_VALID;

break;

case TelephonyManager.SIM_STATE_UNKNOWN :

case TelephonyManager.SIM_STATE_ABSENT :

case TelephonyManager.SIM_STATE_PIN_REQUIRED :

case TelephonyManager.SIM_STATE_PUK_REQUIRED :

case TelephonyManager.SIM_STATE_NETWORK_LOCKED :

default:

simState = SIM_INVALID;

break;

}

双SIM卡，监听状态

SIM卡状态改变的action是android.intent.action.SIM_STATE_CHANGED，需要在Manifest.xml进行注册。

@Override

public void onReceive(Context context, Intent intent) {

super.onReceive(context, intent);

final String action = intent.getAction();

Log.i(TAG,"++++++Action:"+action);

if("android.intent.action.SIM_STATE_CHANGED".equals(action)){

Log.d(TAG,"###############start");

setSimInfoByChange(context,intent);

}

private void setSimInfoByChange(Context context,Intent intent){

//subid 卡ID

int subId = intent.getIntExtra(PhoneConstants.SUBSCRIPTION_KEY, SubscriptionManager.INVALID_SUBSCRIPTION_ID);

//soltId 卡槽ID 0：卡槽一 1：卡槽二

int soltId = intent.getIntExtra("slot",SOLTID);

Log.d(TAG, " #######subId:"+subId);

Bundle mBundle = intent.getExtras();//从中可以看到intent的发送过来的数据

Log.d(TAG, " #######mBundle:"+mBundle.toString());

String stateExtra = intent.getStringExtra(IccCardConstants.INTENT_KEY_ICC_STATE);

if (stateExtra!=null) {

if (stateExtra.equals("ABSENT")) { //卡拔出状态

SIM_STATE = 1;

SimInfo = context.getString(R.string.cell_broadcast_widget_no_sim_card, "No SIM Cards");

} else if (stateExtra.equals("READY") || //卡正常状态即可以读出卡信息

stateExtra.equals("IMSI") ||

stateExtra.equals("LOADED") ){

SIM_STATE = 0;

}else if(stateExtra.equals("LOCKED") || //卡被锁状态

stateExtra.equals("NOT_READY") ||

stateExtra.equals("PIN")||

stateExtra.equals("PUK")){

SIM_STATE = 2;

SimInfo = context.getString(R.string.cell_broadcast_widget_no_service,"No Services");

}

Log.d(TAG, " #######stateExtra:"+stateExtra+"+++++SimInfo:"+SimInfo);

Log.d(TAG, " #######soltId:"+soltId);

}

通过这个intent可以找到相应的SIM及卡槽信息，同时

String stateExtra = intent.getStringExtra(IccCardConstants.INTENT_KEY_ICC_STATE);

这个方法可以获取SIM卡改变的状态情况，在icccardconstants的API中可以发现有这些状态:

com.android.Internal.telephony.IccCard

type

name

value

protected static final int

EVENT_ICC_LOCKED_OR_ABSENT

protected static final int

EVENT_ICC_READY

protected static final int

EVENT_RADIO_OFF_OR_NOT_AVALIABLE
