这段代码对我有用。希望对你有帮助

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.TelephonyManager;
import android.util.Log;

public class CallStateReceiver extends BroadcastReceiver {

private final String LOG_TAG = "CallStateReceiver";

public static String prevState = TelephonyManager.EXTRA_STATE_IDLE;

@Override
public void onReceive(Context context, Intent intent) {

    Bundle bundle = intent.getExtras();
    if (bundle == null) {
        return;
    }

    String state = bundle.getString(TelephonyManager.EXTRA_STATE);

    if (state.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_IDLE)
            && !prevState.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_IDLE)) {

        Log.i(this.LOG_TAG, "Call ended"));
    }

    prevState = state;
}
}
