Android Phone_状态未接听来电

如果我从shell中给出

android.intent.action.PHONE\u STATE

intent，我工作中的问题是它可以工作，但不能得到电话号码。但主要的问题是，当我打电话给我的手机，它并没有得到任何效果。当应用程序关闭时，我用其他手机呼叫我的手机时有什么问题，为什么不接听此呼叫

这里是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>

检查这个代码，它对我有效

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);
    }
}

谢谢你，拉梅什。这是我现在的工作。但是数字还没有显示。检查权限，如果您使用的是Android 6.0棉花糖，为什么在广播接收器中创建侦听器？

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);
    }
}
