Android实现自动填充验证码

实现步骤:

创建Receiver
静态注册Receiver
监听Activity回调获取验证码
验证码的解析与填充

1.Receiver的创建与回调的创建

public class MyReceiver extends BroadcastReceiver {
    private static final String TAG = "MainActivityInfo";
    public CallBack callBack ;
    public interface  CallBack{
        void setMsg(String s);
    }
    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED")) {
            Log.i(TAG, "onReceive: ");
            StringBuilder builder = new StringBuilder();
            //接收由SMS传过来的数据
            Bundle bundle = intent.getExtras();
            //判断是否由数据
            if (bundle != null) {
                //通过pdus可以接收到的所有短信消息
                Object[] pdus = (Object[]) bundle.get("pdus");
                //构建短信对象array，并依据收到短信长度来构建array的大小
                SmsMessage[] smsMessages = new SmsMessage[pdus.length];
                for (int i = 0; i < smsMessages.length; i++) {
                    smsMessages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
                }
                //将收来的短信合并自定义短信于StringBuild当中
                for (SmsMessage message : smsMessages) {
                    builder.append("短信来源");
                    //获取短信的号码
                    builder.append(message.getDisplayOriginatingAddress());
                    //获取短信的内容
                    builder.append("\n短信内容\n");
                    builder.append(message.getDisplayMessageBody());
                }
                System.out.println(builder.toString());
                callBack = MainActivity.callBack;
                callBack.setMsg(builder.toString());
            }
        }
    }
}

2.静态注册Receiver(注册之后才可以接收到收到的短信)

<receiver android:name=".MyReceiver">
<intent-filter android:priority="800"> //优先级
    <action                             android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>

3.Activity通过回调获取到短信

public class MainActivity extends AppCompatActivity implements MyReceiver.CallBack{
    private TextView tv_content ;
    public static MyReceiver.CallBack callBack ;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        callBack = this;
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        SharedPreferences preferences = getSharedPreferences("Brioal", MODE_WORLD_READABLE);
        SharedPreferences.Editor editor = preferences.edit();
        editor.putString("Desc", "监听收到的短信，可用于自动填写验证码");
        editor.apply();
        FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                startActivity(new Intent(MainActivity.this, SummaryActivity.class));
            }
        });
        tv_content = (TextView) findViewById(R.id.main_tv_content);
    }
    @Override
    public void setMsg(String s) {
       ///短信内容的解析与填充
       ...
    }
