我需要检查 Sim 卡状态并根据其状态执行多项操作。 根据我对BroadcastReceiver的理解，当Sim State改变时，会执行broadcastReceiver的onReceive方法。
这是 BroadcastReceiver 类:
public class SimStateListener extends BroadcastReceiver {
public SimStateListener() {
}
@Override
public void onReceive(Context context, Intent intent) {
// TODO: This method is called when the BroadcastReceiver is receiving
// an Intent broadcast.
// Checks Sim card State
TelephonyManager telephoneMgr = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
int simState = telephoneMgr.getSimState();
switch (simState) {
case TelephonyManager.SIM_STATE_ABSENT:
Log.i("SimStateListener", "Sim State absent");
break;
case TelephonyManager.SIM_STATE_NETWORK_LOCKED:
Log.i("SimStateListener", "Sim State network locked");
break;
case TelephonyManager.SIM_STATE_PIN_REQUIRED:
Log.i("SimStateListener", "Sim State pin required");
break;
case TelephonyManager.SIM_STATE_PUK_REQUIRED:
Log.i("SimStateListener", "Sim State puk required");
break;
case TelephonyManager.SIM_STATE_UNKNOWN:
Log.i("SimStateListener", "Sim State unknown");
break;
case TelephonyManager.SIM_STATE_READY:
Log.i("SimStateListener", "Sim State ready");
String phoneNumber = telephoneMgr.getLine1Number();
Log.i("SimStateListener", phoneNumber);
Toast.makeText(context, phoneNumber, Toast.LENGTH_LONG).show();
if(phoneNumber.equals(myPhoneNumber)){
// do nothing
break;
}
else{
Log.i("SimStateListener", "Sim card is changed");
// do something
break;
}
}
}
}
这是我在 list 中放入的内容:
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<receiver android:name="com.example.trackyourandroid.SimStateListener" android:enabled="true" android:exported="true" >
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
</receiver>
这是我在 LogCat 中得到的内容:

我无法在 LogCat 中打印任何内容，也没有看到任何 Toast 出现。
你能告诉我我做错了什么吗？
最佳答案
你的 Intent 过滤器是错误的，尝试使用这个:
<intent-filter>
<action android:name="android.intent.action.SIM_STATE_CHANGED" />
</intent-filter>
关于android - 发送广播 Intent SIM_STATE_CHANGED 失败，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/20662178/
