    什么是p2p

    P2P金融又叫P2P信贷

    P2P:person to person / Peer to Peer;
    

    信贷:信用贷款

    P2P金融指个人与个人间的小额借贷交易,一般需要借助电子商务专业网络平台帮助借贷双方确立借贷关系并完成相关交易手续。

    电子商务网络平台指什么?

    指的就是经营P2P金融业务的公司开发的线上移动APP、网站、pc端软件。通过这些平台帮助借贷双方确定借贷关系并完成相关交易手续。(对于我们Android开发,我们需要关注的就是移动端App软件的P2P金融平台)

    2. 服务器

    服务器部署在本地Tomcat访问地址:

    http://localhost/P2PInvest/
    

    具体资源访问地址应该设置成相应的Ip和端口号

    3. Android 客户端

    UI基本框架

    image

    01-主界面activity_main.xml的设置

    <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout 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"
                  android:background="#ffffff"
                  android:orientation="vertical"
                  >

                style="@style/MainButtonStyle"
                android:drawableTop="@drawable/assets_button_selector"
                android:textColor="@drawable/buttom_assets_text_selector"
                android:text="我的资产" />
    
            <RadioButton
                android:id="@+id/rb_more"

            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            android:layout_centerHorizontal="true"
            android:layout_marginBottom="100dp"
            android:orientation="horizontal">
    
            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="当前版本:"
                android:textColor="@color/white"

                android:textColor="@color/white"
                android:textSize="15sp" />
    
        </LinearLayout>
    
    </RelativeLayout>
    

    设置为全屏显示

    方式一:动态编码的方式:
    // 去掉窗口标题
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    // 隐藏顶部的状态栏
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
    setContentView();
    方式二:
    android:theme="@android:style/Theme.Black.NoTitleBar"
    android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen"
     
    方式三
    <style name="AppTheme" parent="AppBaseTheme">
    <item name="android:windowNoTitle">true</item><!-- 没有标题 -->
