Question

如果我从shell中提出android.intent.action.PHONE_STATE意图，我的工作中的问题是有效但却没有获取电话号码。但主要的问题是，当我拨打手机时，它没有任何效果。当应用关闭时我用其他手机拨打手机有什么问题，为什么不接听这个电话？

这是AndroidManifest.xml

    <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="homework.contactor">

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

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <receiver android:name=".ServiceReceiver">
            <intent-filter>
                <action android:name="android.intent.action.PHONE_STATE" />
            </intent-filter>
        </receiver>
    </application>

</manifest>

以下是接收者代码：

package homework.contactor;

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

class MyPhoneStateListener extends PhoneStateListener {

    public static Boolean phoneRinging = false;

    public void onCallStateChanged(int state, String incomingNumber) {

        switch (state) {
            case TelephonyManager.CALL_STATE_IDLE:
                Log.d("DEBUG", "IDLE");
                phoneRinging = false;
                break;
            case TelephonyManager.CALL_STATE_OFFHOOK:
                Log.d("DEBUG", "OFFHOOK");
                phoneRinging = false;
                break;
            case TelephonyManager.CALL_STATE_RINGING:
                Log.d("DEBUG", "RINGING");
                phoneRinging = true;

                break;
        }
    }
}

public class ServiceReceiver extends BroadcastReceiver {
    TelephonyManager telephony;

    public void onReceive(Context context, Intent intent) {
        MyPhoneStateListener phoneListener = new MyPhoneStateListener();
        telephony = (TelephonyManager) context
                .getSystemService(Context.TELEPHONY_SERVICE);
        telephony.listen(phoneListener, PhoneStateListener.LISTEN_CALL_STATE);
    }

    public void onDestroy() {
        telephony.listen(null, PhoneStateListener.LISTEN_NONE);
    }

}

检查此代码，它对我有用

public class ServiceReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(final Context context, Intent intent) {
        TelephonyManager telephony = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
        telephony.listen(new PhoneStateListener() {
            @Override
            public void onCallStateChanged(int state, String incomingNumber) {
                super.onCallStateChanged(state, incomingNumber);
                Toast.makeText(MainActivity.this, "" + incomingNumber, Toast.LENGTH_SHORT).show();
            }
        }, PhoneStateListener.LISTEN_CALL_STATE);
    }
}

Android Phone_State没有收到来电
