android - PhoneStateListener在三星GT-S7562上不起作用

我正在三星GT-S7562（双SIM-4.0）上测试phoneStateListener，然后state总是返回0，传入号码总是返回空。虽然它在我的另一个设备三星GT-S5570（单SIM-2.2）上运行良好。这是我的密码。

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.util.Log;
import android.widget.Toast;

public class IncomingCall extends BroadcastReceiver {
    Context pcontext;

    public void onReceive(Context context, Intent intent) {
        pcontext = context;

        try {
            TelephonyManager tmgr = (TelephonyManager) context
                    .getSystemService(Context.TELEPHONY_SERVICE);

            MyPhoneStateListener PhoneListener = new MyPhoneStateListener();

            tmgr.listen(PhoneListener, PhoneStateListener.LISTEN_CALL_STATE);

        } catch (Exception e) {
            Log.e("Phone Receive Error", " " + e);
        }

    }

    private class MyPhoneStateListener extends PhoneStateListener {
        public void onCallStateChanged(int state, String incomingNumber) {
            switch (state) {
            case TelephonyManager.CALL_STATE_IDLE:
                Toast.makeText(
                        pcontext,
                        "CALL_STATE_IDLE.\nIncomming Number : "
                                + incomingNumber, Toast.LENGTH_SHORT).show();
                break;
            case TelephonyManager.CALL_STATE_OFFHOOK:
                Toast.makeText(
                        pcontext,
                        "CALL_STATE_OFFHOOK.\nIncomming Number : "
                                + incomingNumber, Toast.LENGTH_SHORT).show();
                break;
            case TelephonyManager.CALL_STATE_RINGING:
                Toast.makeText(
                        pcontext,
                        "CALL_STATE_RINGING.\nIncomming Number : "
                                + incomingNumber, Toast.LENGTH_SHORT).show();
                break;
            default: {
                Toast.makeText(pcontext,
                        "Default.\nIncomming Number : " + incomingNumber,
                        Toast.LENGTH_SHORT).show();
            }
            }
        }
    }
}

在menifest文件中还添加了permission。

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

<receiver android:name="com.example.caller.ServiceReceiver" >
            <intent-filter>
                <action android:name="android.intent.action.PHONE_STATE" />
            </intent-filter>
        </receiver>

最佳答案

PhoneStateListener不能在很多设备上工作，特别是在华为和中兴。
你可以试试这个：

public class PhoneStateReceiver extends BroadcastReceiver {
private static final String TAG = PhoneStateReceiver.class.getSimpleName();
private static String incoming_number = null;

@Override
public void onReceive(Context context, Intent intent) {
    if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)) {
        String phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);    // outgoing call
        Log.i(TAG, "call OUT:" + phoneNumber);
    } else {
        TelephonyManager tm = (TelephonyManager) context.getSystemService(Service.TELEPHONY_SERVICE);

        switch (tm.getCallState()) {
        case TelephonyManager.CALL_STATE_RINGING:  // incoming call
            incomingFlag = true;
            incoming_number = intent.getStringExtra("incoming_number");
            LogUtils.d(TAG, "RINGING :" + incoming_number);
            break;
        case TelephonyManager.CALL_STATE_OFFHOOK:
            if (incomingFlag) {
                LogUtils.d(TAG, "incoming ACCEPT :" + incoming_number);
            }
            break;

        case TelephonyManager.CALL_STATE_IDLE:
            if (incomingFlag) {     // hang up

                LogUtils.d(TAG, "incoming IDLE, number:" + incoming_number);
            }
            break;
        }
    }
}

显示：

<receiver android:name=".receiver.PhoneStateReceiver" android:exported="false" >
        <intent-filter>
            <action android:name="android.intent.action.PHONE_STATE" />
        </intent-filter>
    </receiver>

但我不确定这个广播是否一直有效。我同时使用这两种方式。它工作得很好。祝你好运。
