android中如何自动获取短信验证码

	/**
	 * 匹配短信中间的6个数字（验证码等）
	 * 
	 * @param patternContent
	 * @return
	 */

		if (TextUtils.isEmpty(patternContent)) {
			return null;
		}
		Pattern p = Pattern.compile(patternCoder);
		Matcher matcher = p.matcher(patternContent);
		if (matcher.find()) {
			return matcher.group();
		}
		return null;
	}
}

 添加权限:

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

 activity_main.xml

<RelativeLayout 
	xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <EditText
        android:id="@+id/et"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:gravity="center_horizontal"
        android:hint="@string/smscontent" />
</RelativeLayout>
