Android项目实战_手机安全卫士splash界面

- 根据代码的类型组织包结构

1. 界面 com.hb.mobilesafe.activities

2. 服务 com.hb.mobilesafe.services

3. 业务逻辑 com.hb.mobilesafe.engine

4. 数据库 com.hb.mobilesafe.db

5. 数据库增删改查 com.hb.mobilesafe.db.dao

6. 工具类 com.hb.mobilesafe.utils

7. 自定义view com.hb.mobilesafe.ui

###3.splash界面的作用

1. 展现产品的logo,提升产品的知名度.

2. 初始化应用程序的数据.

3. 连接服务器,查找可更新的版本,自动更新

4. 用户操作指南

5. 新版本特性提醒

4.布局文件的命名规则

SplashActivity--->activity_spalsh.xml

XxxActivity---> activity_xxx.xml

###5.获取应用程序版本号

//用PackageManager拿到PackageInfo,PackageInfo中的versionName

PackageInfo packinfo = context.getPackageManager().getPackageInfo(

context.getPackageName(), 0);

String version = packinfo.versionName;

###6.源代码版本控制

- 安装VisualSVN Server——SVN服务器,一直下一步即可

- 导入仓库到服务器

1.在Repositories处右键,选择Import Existing Repository

2.选择Copy repository from another location,下一步

3.点击Browse,选择仓库路径,"代码/代码仓库/Repository/mobilesafe",点击下一步

4.点击Import

5.点击Finish,导入完成

- 安装TortoiseSVN——SVN客户端,一直下一步即可

1.在想要检出代码的地方右键,选择SVN Checkout

2.URL of repository处填https://127.0.0.1/svn/mobilesafe/,地址也可以从SVN服务器的mobilesafe处右键选择Copy URL to clipboard拷贝

3.Checkout directory出填写检出代码要放的位置,然后点击OK

4.完成代码的检出

- 将代码更新到指定版本

1.mobilesafe文件夹出右键,选择Update to version

2.点击show log

3.点击左下角的show all

4.选择要更新的版本,点击OK

5.版本更新完成

###7.应用自动更新的逻辑图

![](http://i.imgur.com/EU78wXt.png)

###8.获取服务器版本号

//获取服务器地址

String path = getResources().getString(R.string.url);

URL url = new URL(path);

//创建网络连接

HttpURLConnection conn = (HttpURLConnection) url.openConnection();

conn.setRequestMethod("GET");

conn.setConnectTimeout(5000);

//发出请求,获得返回码

int code = conn.getResponseCode();

if(code ==200){

//获取服务器返回的流并进行解析

InputStream is = conn.getInputStream();

String result = StreamTools.readStream(is);

//转化为json并解析出版本号

JSONObject json = new JSONObject(result);

String serverVersion = json.getString("version");

Log.i(TAG,"服务器版本:"+serverVersion);

}

###9.将流转化为字符串

public static String readStream(InputStream is) throws IOException{

//ByteArrayOutputStream类是在创建它的实例时,程序内部创建一个byte型数组的缓冲区,缓冲区会随着数据的不断写入而自动增长。可使用 toByteArray()和 toString()获取数据

ByteArrayOutputStream baos = new ByteArrayOutputStream();

byte[] buffer = new byte[1024];

int len = -1;

while((len = is.read(buffer))!=-1){

baos.write(buffer, 0, len);

}

is.close();

return baos.toString();

}

###10.弹出对话框

1.使用AlertDialog.Builder

2.设置标题、信息、点击事件等

3.调用show方法显示出来,调用dismiss方法消失

###11.下载apk

1.使用开源框架xUtils

2.使用HttpUtils的download方法,填入三个参数:服务器下载地址,手机中的存储位置、回调事件

3.回调事件中有三个常用的方法:onSuccess下载成功、onFailure下载失败、onLoading更新下载进度

xUtils补充

###12.安装apk

1.调用系统的安装apk的界面,传入对应的参数

2.具体实现方式

Intent intent = new Intent();

intent.setAction("android.intent.action.VIEW");

intent.addCategory("android.intent.category.DEFAULT");

intent.setDataAndType(

Uri.fromFile(fileinfo.result),

"application/vnd.android.package-archive");

startActivity(intent);

###13.应用程序的覆盖安装要满足的条件

1. 两个版本签名一致

2. 两个版本包名一致

###14.跑马灯效果的TextView

1. 系统的TextView不能获取焦点,使用自定义控件

2. 继承TextView控件,重写isFocused方法,直接返回true,让其获取焦点

3. 设置android:ellipsize="marquee"

###15.旋转的弘博logo

1. 使用系统提供的属性动画

2. 具体实现方式

ObjectAnimator oa = ObjectAnimator.ofFloat(iv_home_logo, "rotationY",

45, 90, 135, 180, 225, 270, 315);

oa.setDuration(3000);

oa.setRepeatCount(ObjectAnimator.INFINITE);

oa.setRepeatMode(ObjectAnimator.RESTART);

oa.start();
