要实现自动获取短信验证码功能,你可以使用以下步骤:
1. 在AndroidManifest.xml文件中添加以下权限:
<uses-permission android:name="android.permission.RECEIVE_SMS" /><uses-permission android:name="android.permission.READ_SMS" />
2. 创建一个BroadcastReceiver类来接收短信:
public class SMSReceiver extends BroadcastReceiver {private static final String SMS_RECEIVED = "android.provider.Telephony.SMS_RECEIVED";
@Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(SMS_RECEIVED)) {
Bundle bundle = intent.getExtras();
if (bundle != null) {
Object[] pdus = (Object[]) bundle.get("pdus");
if (pdus != null) {
for (Object pdu : pdus) {
SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) pdu);
String messageBody = smsMessage.getMessageBody();
// 在这里处理短信内容
}
}
}
}
}
}
3. 在你的Activity中注册SMSReceiver:
private SMSReceiver smsReceiver;@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
smsReceiver = new SMSReceiver();
IntentFilter intentFilter = new IntentFilter("android.provider.Telephony.SMS_RECEIVED");
registerReceiver(smsReceiver, intentFilter);
}
@Override
protected void onDestroy() {
super.onDestroy();
unregisterReceiver(smsReceiver);
}
这样,当你的应用在前台运行时,SMSReceiver将会自动接收到短信并在onReceive方法中处理短信内容。你可以根据自己的需求对短信内容进行解析,获取验证码等操作。请注意,由于Android 4.4及以上版本对SMS_RECEIVED广播进行了限制,只有用户选择你的应用作为默认短信应用时,才能收到短信。
