Android+json+php+mysql realizes user feedback function

I believe that every project will have user feedback suggestions and other functions, the implementation of a lot of methods, the following is my way to achieve, for everyone to communicate. First look at the concrete interface, three fields. Name, the mailbox is optional, can be empty, the suggestion cannot be empty. If you need, you can leave a message for me.

The following is a layout code that uses a <include layout= "@layout/uphead" > is to introduce another layout file into this layout.

<?xml version= "1.0" encoding= "Utf-8"?> <linearlayout xmlns:android= "http://schemas.android.com/apk/res/" Android "Android:layout_width=" Match_parent "android:layout_height=" match_parent "android:orientation=" Vertica L "android:background=" @color/bg_gray "> <include layout=" @layout/uphead "/> <!--Name Lab El--> <textview android:layout_width= "fill_parent" android:layout_height= "Wrap_content" Android : text= "name (optional)" android:paddingleft= "10dip" android:paddingright= "10dip" android:textcolor= "@color
