在Android上以编程方式获取来电号码 [英] Get incoming call number programmatically on android

问题描述

我正在尝试使用android studio上的广播接收器获取来电信息.以下是我尝试过的方法:

I am trying to get incoming call info using broadcast receivers on android studio. following are the methods i tried:

<receiver android:name=".receivers.IncomingCalls">
            <intent-filter>
                <action android:name="android.intent.action.PHONE_STATE" />
            </intent-filter>
        </receiver>

我尝试了此接收者的意图:

On this receiver's intent i tried:

方法一:

incnumber=intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);

方法二:

final String state1 = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
        telephony.listen(new PhoneStateListener(){
            @Override
            public void onCallStateChanged(int state, final String incomingNumber) {
                super.onCallStateChanged(state, incomingNumber);
                incnumber=incomingNumber;
            }
        },PhoneStateListener.LISTEN_CALL_STATE);

方法三:

incnumber=intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);

这三种方法都返回空的incnumber.

All the three methods return empty incnumber.

顺便说一句，我正在android pie上运行此项目，请帮帮我.

By the way, I am running this project on android pie, Please help me out.

推荐答案

尝试这种方式...权限

Try this way... permission

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

让广播接收者说ServiceReceiver在清单中分配其动作.

Make a Broadcast receiver say ServiceReceiver assign its action in Manifest.

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

ServiceReceiver.Java

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);
            System.out.println("incomingNumber : "+incomingNumber);
        }
    },PhoneStateListener.LISTEN_CALL_STATE);
}

}
