android 实战练习 回归手机卫士 一 主界面布局

学习android一年多了，平常都是看着书，然后做些练习，总觉着学了后面，忘了前面，突然想做一个比较完整一点的项目，

于是不自觉地就想到了做这样一个应用，由于刚接触android没多久，程序肯定会存在或多或少的bug

不过现已大体为准吧，把所有的知识整体地复习和应用一遍也是不错的

以下是效果图

 

今天就先上布局了，相关的业务逻辑后续再说吧

其实这也就是简单的fragment+viewpager的整体布局，然后零零散散地加上一些其他诸如ListView,GridView等布局

1.activity_main.xml主界面

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:id="@+id/spalsh_ui"    android:layout_width="match_parent"    android:layout_height="match_parent"     >    <LinearLayout         android:id="@+id/home_title_layout"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:orientation="horizontal"        android:layout_alignParentTop="true"        android:background="@color/activity_mian_title">        <ImageView             android:id="@+id/activity_main_home_img"            android:layout_width="40dip"            android:layout_height="45dip"            android:src="@drawable/user_default"             android:contentDescription="@string/home_img"/>        <TextView             android:id="@+id/activity_main_title"            android:layout_width="0dip"            android:layout_height="wrap_content"            android:layout_weight="2"            android:text="@string/logo_title"            android:textSize="20sp"            android:gravity="center"            android:layout_gravity="center"            android:textColor="@color/activity_mian_title_text"/>        <ImageButton             android:id="@+id/activity_main_menu"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_weight="0"            android:src="@drawable/main_menu"            android:contentDescription="@string/home_img"/>    </LinearLayout>        <android.support.v4.view.ViewPager        android:id="@+id/activity_main_viewPager"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:layout_below="@id/home_title_layout"        />        <LinearLayout         android:layout_width="match_parent"        android:layout_height="wrap_content"        android:orientation="horizontal"        android:layout_above="@id/activity_main_viewPager"        android:layout_alignParentBottom="true"        android:background="@color/activity_mian_title">        <TextView             android:id="@+id/activity_main_index"            style="@style/activity_bottom_text"            android:drawableTop="@drawable/menu_index"            android:text="@string/activity_index"/>        <TextView             android:id="@+id/activity_main_youhua"            style="@style/activity_bottom_text"            android:drawableTop="@drawable/menu_youhua"            android:text="@string/activity_youhua"/>        <TextView             android:id="@+id/activity_main_manager"            style="@style/activity_bottom_text"            android:drawableTop="@drawable/menu_manager"            android:text="@string/activity_manager"/>        <TextView             android:id="@+id/activity_main_setting"            style="@style/activity_bottom_text"            android:drawableTop="@drawable/menu_setting"            android:text="@string/activity_setting"/>     </LinearLayout></RelativeLayout>

2.activity代码

package cn.edu.gzu.BackPP.activities;import java.io.File;import java.util.ArrayList;import cn.edu.gzu.BackPP.Fragment.IndexFragment;import cn.edu.gzu.BackPP.Fragment.ManagerFragment;import cn.edu.gzu.BackPP.Fragment.SettingFragment;import cn.edu.gzu.BackPP.Fragment.YouhuaFragment;import android.content.Intent;import android.os.Bundle;import android.os.Environment;import android.support.v4.app.Fragment;import android.support.v4.app.FragmentActivity;import android.support.v4.view.ViewPager;import android.support.v4.view.ViewPager.OnPageChangeListener;import android.view.Gravity;import android.view.KeyEvent;import android.view.MotionEvent;import android.view.View;import android.view.View.OnClickListener;import android.view.View.OnTouchListener;import android.widget.TextView;import android.widget.Toast;public class MainActivity extends FragmentActivity implements OnTouchListener{private Fragment indexFragment;// 获取到fragment实例private Fragment youhuaFragment;private Fragment managerFragment;private Fragment settingFragment;private ArrayList<Fragment> myFragments;// 由于存放fragment的集合private ViewPager viewPager;// 让fragment切换并装载的控件private TextView indexSwitcher;// 页面底部的四个切换组件private TextView youhusSwitcher;private TextView managerSwitcher;private TextView settingSwitcher;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);requestWindowFeature(Window.FEATURE_NO_TITLE);setContentView(R.layout.activity_main);// 初始化加载fragmentinitFragment();// 通过id找到组件findViewById();//在外部存储sdcard上建立文件夹以便后续保存文件File fileDir=new File(Environment.getExternalStorageDirectory().getPath()+"/HuiGui/cache");if(!fileDir.exists()){fileDir.mkdirs();}View view = getWindow().getDecorView();view.setOnTouchListener(this);startServices();}/** * 初始化加载fragment */private void initFragment() {myFragments = new ArrayList<Fragment>();indexFragment = new IndexFragment();youhuaFragment = new YouhuaFragment();managerFragment = new ManagerFragment();settingFragment = new SettingFragment();// 将fragment实例添加到集合myFragments.add(indexFragment);myFragments.add(youhuaFragment);myFragments.add(managerFragment);myFragments.add(settingFragment);viewPager = (ViewPager) findViewById(R.id.activity_main_viewPager);viewPager.setAdapter(new MyFragmentAdapter(getSupportFragmentManager(),myFragments));viewPager.setCurrentItem(0);viewPager.setOnPageChangeListener(new OnPageChangeListener() {@Overridepublic void onPageSelected(int arg0) {switch (arg0) {case 0:initTitleBG();indexSwitcher.setBackgroundResource(R.drawable.pressed_bg);break;case 1:initTitleBG();youhusSwitcher.setBackgroundResource(R.drawable.pressed_bg);break;case 2:initTitleBG();managerSwitcher.setBackgroundResource(R.drawable.pressed_bg);break;case 3:initTitleBG();settingSwitcher.setBackgroundResource(R.drawable.pressed_bg);break;}}@Overridepublic void onPageScrolled(int arg0, float arg1, int arg2) {}@Overridepublic void onPageScrollStateChanged(int arg0) {}});};/** * 通过id找到组件 */private void findViewById() {indexSwitcher = (TextView) findViewById(R.id.activity_main_index);youhusSwitcher = (TextView) findViewById(R.id.activity_main_youhua);managerSwitcher = (TextView) findViewById(R.id.activity_main_manager);settingSwitcher = (TextView) findViewById(R.id.activity_main_setting);indexSwitcher.setBackgroundColor(getResources().getColor(R.color.activity_mian_bottom_selected));ViewOnClickListener viewOnClickListener = new ViewOnClickListener();indexSwitcher.setOnClickListener(viewOnClickListener);youhusSwitcher.setOnClickListener(viewOnClickListener);managerSwitcher.setOnClickListener(viewOnClickListener);settingSwitcher.setOnClickListener(viewOnClickListener);}/** * initHomeTitle background rescource */private void initTitleBG() {indexSwitcher.setBackgroundColor(getResources().getColor(R.color.activity_mian_title));youhusSwitcher.setBackgroundColor(getResources().getColor(R.color.activity_mian_title));managerSwitcher.setBackgroundColor(getResources().getColor(R.color.activity_mian_title));settingSwitcher.setBackgroundColor(getResources().getColor(R.color.activity_mian_title));}/** * 组件监听其 */private class ViewOnClickListener implements OnClickListener {@Overridepublic void onClick(View v) {switch (v.getId()) {case R.id.activity_main_index:viewPager.setCurrentItem(0);break;case R.id.activity_main_youhua:viewPager.setCurrentItem(1);break;case R.id.activity_main_manager:viewPager.setCurrentItem(2);break;case R.id.activity_main_setting:viewPager.setCurrentItem(3);break;}}}}

3.建立相应的fragment实例，并加载相应的布局文件，这里只列举其中一页，其他页可相应建立

package cn.edu.gzu.BackPP.Fragment;import cn.edu.gzu.BackPP.Dao.Const;import cn.edu.gzu.BackPP.activities.R;import android.content.Context;import android.os.Bundle;import android.support.v4.app.Fragment;import android.view.LayoutInflater;import android.view.View;import android.view.View.OnClickListener;public class SettingFragment extends Fragment implements OnClickListener {@Overridepublic void onActivityCreated(Bundle savedInstanceState) {super.onActivityCreated(savedInstanceState);}@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {View view = inflater.inflate(R.layout.activity_main_fragment_setting,container, false);return view;}}

4.xml布局（普通布局文件）

5.fragment适配器

package cn.edu.gzu.BackPP.adapter;import java.util.ArrayList;import android.support.v4.app.Fragment;import android.support.v4.app.FragmentManager;import android.support.v4.app.FragmentPagerAdapter;public class MyFragmentAdapter extends FragmentPagerAdapter{private ArrayList<Fragment> myFragments;public MyFragmentAdapter(FragmentManager fm) {super(fm);}public MyFragmentAdapter(FragmentManager fragmentManager,ArrayList<Fragment> myFragments) {super(fragmentManager);this.myFragments=myFragments;}@Overridepublic Fragment getItem(int arg0) {return myFragments.get(arg0);}@Overridepublic int getCount() {return myFragments.size();}@Overridepublic int getItemPosition(Object object) {return super.getItemPosition(object);}}

这样就可以实现能左右滑动的主界面了，效果基本上实现如效果图所示，由于其他三页也都是差不多的布局，有时间的话，后续再贴出来

可能界面不是很漂亮，不过目的也就是为了练习，大部分图片都在网上搜的，没办法了
