public class BroadcastExaple extends Activity {
TextView textOut;
TelephonyManager telephonyManager;
PhoneStateListener listener;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
try {
super.onCreate(savedInstanceState);
// Get the UI
textOut = new TextView(this);
textOut.setText("DEmoBroadCast");
setContentView(textOut);
// Get the telephony manager
telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
// Register the listener wit the telephony manager
telephonyManager.listen(listener,PhoneStateListener.LISTEN_CALL_STATE);
// Create a new PhoneStateListener
listener = new PhoneStateListener() {
@Override
public void onCallStateChanged(int state, String incomingNumber) {
Log.d("DEBUG", "Phone listener....");
String stateString = "N/A";
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
stateString = "Idle";
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
stateString = "Off Hook";
break;
case TelephonyManager.CALL_STATE_RINGING:
stateString = "Ringing";
break;
}
textOut.append(String.format("\nonCallStateChanged: %s",
stateString));
}
};
} catch (Exception e) {
}
}
}

最佳答案
监听器在使用后创建。
