Android接受驗證碼自動填入功能(源碼+已實現+可用+版本兼容)

實際應用開發中,會經常用到短信驗證的功能,這個時候如果再讓用戶就查看短信.然后再回到界面進行短信的填寫,難免有多少有些不方便,作為開發者.本着用戶至上的原則我們也應該來實現驗證碼的自動填寫功能，還有一個重要的原因是為了防止惡意注冊。今天實現這個功能的方法是用的廣播來實現的

首先在AndroidMainfest.xml中加入所需要的權限：

 

<!-- 短信驗證登陸功能需要添加次權限來自動填充驗證碼，用不到可以去掉 -->
    <uses-permission android:name="android.permission.RECEIVE_SMS" />
    <uses-permission android:name="android.permission.READ_SMS" />

 

首先看一下實現的效果，沒效果說再多都沒用，親眼看到的才知道適不適合自己

 

 

中效果看完接下來就看怎么實現的了，這里使用的廣播為動態注冊，因為這個APP在進程殺死之后就不需要監聽這個廣播了，在Activity的onDestory之后注銷廣播。
