Syntax error on tokens, ConstructorHeaderName expected instead & Syntax error on token "(", < expected
提问by user2528574
I'm getting two errors stating Syntax error on tokens, ConstructorHeaderName expected instead & Syntax error on token "(", < expected
我收到两个错误，说明令牌上的语法错误，ConstructorHeaderName 预期而不是令牌“（”，< 预期的语法错误

在线上：
mTM.listen(callListener, PhoneStateListener.LISTEN_CALL_STATE);
...any suggestions?
...有什么建议？
public class DataCountService extends Service {
String text = "USR;1";
String ERROR = Constants.PREFS_NAME;
private Timer timer = new Timer();
private long period;
private long delay_interval;
EndCallListener callListener = new EndCallListener();
TelephonyManager mTM = (TelephonyManager)this.getSystemService(Context.TELEPHONY_SERVICE);
mTM.listen(callListener, PhoneStateListener.LISTEN_CALL_STATE);
private class EndCallListener extends PhoneStateListener {
@Override
public void onCallStateChanged(int state, String incomingNumber) {
if(TelephonyManager.CALL_STATE_RINGING == state) {
// Log.i(LOG_TAG, "RINGING, number: " + incomingNumber);
}
if(TelephonyManager.CALL_STATE_OFFHOOK == state) {
//wait for phone to go offhook (probably set a boolean flag) so you know your app initiated the call.
// Log.i(LOG_TAG, "OFFHOOK");
}
if(TelephonyManager.CALL_STATE_IDLE == state) {
//when this state occurs, and your flag is set, restart your app
// Log.i(LOG_TAG, "IDLE");
}
}
}

The line
线
mTM.listen(callListener, PhoneStateListener.LISTEN_CALL_STATE);
mTM.listen(callListener, PhoneStateListener.LISTEN_CALL_STATE);
is not included in any method. You should put this in the constructor(which seems like what you want) or a regular method.
不包含在任何方法中。你应该把它放在构造函数（这看起来像你想要的）或常规方法中。

mTM.listen(callListener, PhoneStateListener.LISTEN_CALL_STATE);
Should be inside a method, not directly inside class. Refer this questionfor example implementation.
应该在方法内部，而不是直接在类内部。请参阅此问题以获取示例实现。
