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:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<include layout="@layout/layout_main_top" />
<android.support.v4.view.ViewPager
android:id="@+id/vp_mainvp"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1">
</android.support.v4.view.ViewPager>
<TextView
android:layout_width="match_parent"
android:layout_height="0.5dp"
android:background="#737373" />
<TextView
android:layout_width="match_parent"
android:layout_height="0.7dp"
android:background="#101010" />
<include layout="@layout/layout_main_bottom" />
</LinearLayout>
|
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;
/**

*/
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;
}
}

此Fragment对应的xml文件：

现在回到MainActivity中：

package activity;
import ...
public class MainActivity extends FragmentActivity {
private ViewPager mViewPager;
private MyFragmentPagerAdapter mAdapter;
private List<Fragment> 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<Fragment>();
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);
}
}

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<Fragment> fragList;
private List<String> tabList;
public MyFragmentPagerAdapter(FragmentManager fm, List<Fragment> 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();
}
}
|
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：

最后加入的onActivityResult是对应如下情况，如果在某个Fragment中对应进去了其他的Activity时，返回以后导航栏是没有之前的显示的，所以如下就要返回原来的显示。
