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
