Android系统防火墙开发一(2)主界面实现

正如上面的一篇开篇所看到的一样,应用程序的主界面上部分有自定义控件圆形构成,下面是通过详细分析原理实现。
如所示:

上半部分是一个自定义控件,下面部分使用的是九宫格格式的内容,整个布局通过FrameLayout布局构成。
下面来简单介绍一下原理吧!
首先看一下布局代码:
activity_test.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:android_custom="http://schemas.android.com/apk/res/com.example.afhq"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/white" >

    <include
        android:id="@+id/titleId"
        layout="@layout/titlebar" />

    <RelativeLayout
        android:id="@+id/relativeLayout1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_below="@id/titleId"
        android:background="#2bc0ac"
        android:gravity="clip_horizontal" >

        <com.example.afhq.widget.RoundProgressBar
            android:id="@+id/roundProgressBar2"
            android:layout_width="180dip"
            android:layout_height="180dip"
            android:layout_alignParentTop="true"
            android:layout_centerHorizontal="true"
            android:background="#2bc0ac"
            android_custom:roundColor="@android:color/white"
            android_custom:roundProgressColor="@color/battery_view_text_light"
            android_custom:roundWidth="6dip"
            android_custom:textColor="@android:color/white"
            android_custom:textSize="25sp" />
    RelativeLayout>

    <TextView
        android:id="@+id/textView1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_below="@id/relativeLayout1"
        android:layout_centerHorizontal="true"
        android:background="#2bc0ac"
        android:gravity="center"
        android:text="上次体检时间:20:20"
        android:textColor="@color/black" />
 <RelativeLayout
      android:id="@+id/re_button1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="#2bc0ac"
        android:layout_below="@id/textView1"
        android:gravity="clip_horizontal" >
    <Button
        android:id="@+id/button1"
        style="@style/logout_edit_text"
        android:layout_width="match_parent"
        android:layout_height="40dip"
         android:layout_marginLeft="100dip"
        android:layout_marginRight="100dip"
        android:text="一键体检" />
RelativeLayout>
    

    <FrameLayout
        android:id="@+id/activity_test_frag"
        android:layout_width="fill_parent"
        android:layout_height="match_parent"
        android:layout_below="@id/re_button1" >
    FrameLayout>

RelativeLayout>

如上代码可以看出首页布局代码,关于FrameLayout 实现切换布局的原理:
在代码中可以看出:FrameLayout 就是讲不通的页面放到一个容器中,实现切换;下面项目的需要设计,当然关于FrameLayout 原理实现我觉得要去看看源码和基础教程了。
下面看MainActivity.java 实现主界面的构建功能

public class MainActivity extends FragmentActivity {
    private RoundProgressBar mRoundProgressBar5;
    private int progress = 0;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_test);
        ImageView im =(ImageView) findViewById(R.id.titleBarRightImage_setting);
        im.setVisibility(View.VISIBLE);
        //设置界面
        im.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent=new Intent();
                intent.setClass(getApplicationContext(), SettingCenterActivity.class);
                startActivity(intent);
            }
        });

        mRoundProgressBar5 = (RoundProgressBar) findViewById(R.id.roundProgressBar2);
        mRoundProgressBar5.setDefaultStr("一键体检");
        mRoundProgressBar5.setLogoStr("");
        mRoundProgressBar5.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                 startScanningListFragment();
                new Thread(new Runnable() {

                    @Override
                    public void run() {
                        while(progress <= 100){
                            progress += 3;
                            System.out.println(progress);
                            mRoundProgressBar5.setProgress(progress);
                            try {
                                Thread.sleep(1000);
                            } catch (InterruptedException e) {
                                e.printStackTrace();
                            }
                        }
                    }
                }).start();
                Date date=  new Date();
                SimpleDateFormat s=new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
                String da=s.format(date);
                ((TextView)findViewById(R.id.textView1)).setText(da);
            }
        });
        ((Button)findViewById(R.id.button1)).setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                ((Button)findViewById(R.id.button1)).setText("正在体检");
                new Thread(new Runnable() {
                    @Override
                    public void run() {
                        while(progress <= 100){
                            progress += 3;
                            System.out.println(progress);       
                            mRoundProgressBar5.setProgress(progress);
                            try {
                                Thread.sleep(1000);
                            } catch (InterruptedException e) {
                                e.printStackTrace();
                            }
                        }
                    }
                }).start();
            }
        });

        HomeFragment homeFragment=new HomeFragment();
        getSupportFragmentManager()
        .beginTransaction()
        .replace(R.id.activity_test_frag, homeFragment, "").commit();


    }

    public void startScanningListFragment(){
           ScanningListFragment scanningListFragment=new ScanningListFragment();
           getSupportFragmentManager().beginTransaction().
           replace(R.id.activity_test_frag, scanningListFragment).commit();
       }

    /**
     * 
     */
    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {

        if(keyCode==KeyEvent.KEYCODE_BACK){
            return super.onKeyDown(keyCode, event);
        }

        return super.onKeyDown(keyCode, event);
    }
}

当然,每一个fragment的类可以有很多共同的操作,将这共同的操作方法方放在一个举出的base里面,
BaseFragment.java

package com.example.afhq.base;

import android.app.Activity;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public abstract class BaseFragment extends Fragment {
    public View        view;
    public Activity    context;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        context=getActivity();
    }

    @Override
    //设置当前界面view
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        view=initView();
        return view;
    }

    //填充 数据的操作
    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        initData();
    }

    //数据填充UI的方法
    public abstract void initData();

    //预设UI
    public abstract View initView() ;
}

每一个fragment都要继承basefragment,然后实现抽象方法。
主页下面的九宫格就是通过这种形式,实现一个HomeFragment.java的

package com.example.afhq.fragment;

import android.content.Intent;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.LinearLayout;
import android.widget.Toast;

import com.example.afhq.R;
import com.example.afhq.activity.AntiVirusActivity;
import com.example.afhq.activity.LockAppActivity;
import com.example.afhq.activity.MessageInterceptActivity;
import com.example.afhq.activity.RublishcleanActivity;
import com.example.afhq.activity.TasksActivity;
import com.example.afhq.activity.TrafficManagerActivity;
import com.example.afhq.base.BaseFragment;
import com.lidroid.xutils.ViewUtils;
import com.lidroid.xutils.view.annotation.ViewInject;

public class HomeFragment extends BaseFragment {
    @ViewInject(R.id.fragment_main_trojan)
    private LinearLayout fragment_main_trojan;//木马查杀
    @ViewInject(R.id.messagee_linearlayout)//短信拦截
    private LinearLayout messagee_linearlayout;
    @ViewInject(R.id.traffice_manager)
    private LinearLayout traffice_manager;//流量监控
    @ViewInject(R.id.ll_rubbish)
    private LinearLayout ll_rubbish;
    @ViewInject(R.id.task_insert_layer)//软件管理
    private LinearLayout task_insert_layer;
    @ViewInject(R.id.main_layout_applock)
    private LinearLayout main_layout_applock;

    @Override
    public void initData() {
        fragment_main_trojan.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent =new Intent();
                intent.setClass(getActivity(), AntiVirusActivity.class);
                startActivity(intent);
            }
        });
        messagee_linearlayout.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                Intent intent =new Intent();
                intent.setClass(getActivity(), MessageInterceptActivity.class);
                startActivity(intent);
            }
        });
        //流量监控
        traffice_manager.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
//              TrafficManagerActivity 
                Intent intent=new Intent();
                intent.setClass(context, TrafficManagerActivity.class);
                startActivity(intent);

            }
        });
        /**
         * 
         */
        ll_rubbish.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                Intent intent=new Intent();
                intent.setClass(context, RublishcleanActivity.class);
                startActivity(intent);              
            }
        });


        task_insert_layer.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                Intent intent=new Intent();
                intent.setClass(context, TasksActivity.class);
                startActivity(intent);                      
            }
        });

        main_layout_applock.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                Intent intent=new Intent();
                intent.setClass(context, LockAppActivity.class);
                startActivity(intent);                  
            }
        });


    }
    @Override
    public View initView() {
        view= View.inflate(getActivity(), R.layout.fragment_main, null);
        ViewUtils.inject(this,view);
        return view;
    }

}

说到这,上面的布局代码就是这么多,下面就是关于核心的业务需求了,在图上我们可以看出,当点击上面的一键体检的时候,我们需要获取扫描数据,扫描垃圾,扫描卸载残留,扫描大文件,扫描非官方文件,通过定时器实现扫描,下面就是关于扫描的具体代码。

package com.example.afhq.engine;

import java.io.File;
import java.util.ArrayList;
import java.util.List;

import android.content.Context;
import android.content.pm.ApplicationInfo;
import android.content.pm.PackageInfo;
import android.content.pm.PackageManager;
import android.graphics.drawable.Drawable;

import com.example.afhq.domain.AppInfo;

public class AppInfoParser {
    /**
     * 获取手机里面的所有的应用程序
     * @param context 上下文
     * @return
     */
    public static List getAppInfos(Context context){
        //得到一个java保证的 包管理器。
        PackageManager pm = context.getPackageManager();
        List packInfos = pm.getInstalledPackages(0);
        List appinfos = new ArrayList();
        for(PackageInfo packInfo:packInfos){

            String packname = packInfo.packageName;
            appinfo.setPackname(packname);

            appinfo.setIcon(icon);
            String appname = packInfo.applicationInfo.loadLabel(pm).toString();

                //系统应用
                appinfo.setUserApp(false);
            }else{
                //用户应用
                appinfo.setUserApp(true);
            }
            appinfos.add(appinfo);
            appinfo = null;
        }
        return appinfos;
    }

        List appinfos = new ArrayList();
        for(PackageInfo packInfo:packInfos){
            AppInfo appinfo = new AppInfo();
            String packname = packInfo.packageName;
            appinfo.setPackname(packname);
            Drawable icon = packInfo.applicationInfo.loadIcon(pm);
            appinfo.setIcon(icon);
            String appname = packInfo.applicationInfo.loadLabel(pm).toString();
            appinfo.setName(appname);
            //应用程序apk包的路径
            String apkpath = packInfo.applicationInfo.sourceDir;
            appinfo.setApkpath(apkpath);
            File file = new File(apkpath);
            long appSize = file.length();

            }else{
                appinfos.add(appinfo);
                //用户应用
                appinfo.setUserApp(true);
            }
            appinfo = null;
        }
        return appinfos;
    }

}

以上就是简单的介绍一下关于扫描的,主要内容还是在代码中,需要小伙伴们自己去研究一下代码。
