详细说明：
下面是安卓开发仿微信界面的代码。 分为3步，第一步是界面的编写，第二步是导航界面，第三步是右上角菜单栏。 开始第一步前先预览一下效果。 第一步，界面。 界面的思路是利用ViewPager+Fragment实现，所以activity_main.xml中添加一个ViewPager。顶部和底部include的顶部栏和底部栏后面再说。 MainActivity的界面activity_main.xml: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 当然，要用到ViewPager+Fragment就要建立Fragment，如图我建了三个Fragment，这个可以根据需要自己创建。 这三个Fragment很类似，这里写出一个，其他以此类推。 package activity; import android.os.Bundle; import android.support.v4.app.Fragment; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import com.chase.cn.money_of_my.R; /** * Created by Chase on 2017/2/6. */ public class Fragment_tab01 extends Fragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View tab01 = inflater.inflate(R.layout.fragment_tab01_home,container,false); return tab01; } } 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 此Fragment对应的xml文件： 1 2 3 4 5 6 7 现在回到MainActivity中： package activity; import ... public class MainActivity extends FragmentActivity { private ViewPager mViewPager; private MyFragmentPagerAdapter mAdapter; private List fragmentList; //保存界面的view @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); StatusBarUtil.setWindowStatusBarColor(this, R.color.colorTitleGray); initViews(); initDatas(); } /** * 数据初始化 */ private void initDatas() { //fragment数据源 fragmentList = new ArrayList(); fragmentList.add(new Fragment_tab01()); fragmentList.add(new Fragment_tab02()); fragmentList.add(new Fragment_tab03()); mAdapter = new MyFragmentPagerAdapter(getSupportFragmentManager(), fragmentList); mViewPager.setAdapter(mAdapter); } /** * 初始化控件 */ private void initViews() { mViewPager = (ViewPager) findViewById(R.id.vp_mainvp); } } 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 需要编写一个ViewPager的Adapter： package utils; import android.support.v4.app.Fragment; import android.support.v4.app.FragmentManager; import android.support.v4.app.FragmentPagerAdapter; import java.util.List; /** * Created by Chase on 2017/2/6. */ public class MyFragmentPagerAdapter extends FragmentPagerAdapter { private List fragList; private List tabList; public MyFragmentPagerAdapter(FragmentManager fm, List fragList) { super(fm); this.fragList = fragList; } @Override public CharSequence getPageTitle(int position) { return tabList.get(position); } @Override public Fragment getItem(int position) { return fragList.get(position); } @Override public int getCount() { return fragList.size(); } } 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 现在三个Fragment已经添加到了MainActivity中，滑动ViewPager切换Fragment，同时底部的导航栏也会切换，在为ViewPager添加监听以前，先说说底部导航栏。 第二步，底部导航。 这个的切换其实就是切换准备好的png图片和改变文字的颜色。 下面是刚才导入的底部导航栏xml文件： 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 继续回到对应的MainActivity：并加入了按两次回退键退出程序。 package activity;
