Android底部和标签导航栏—TabLayout+Fragment 介绍Google官方在2014年Google I/O上推出了全新的设计语言——Material Design。一并推出了一系列实现Material Design效果的控件库——Android Design Support Library。其中，有TabLayout, NavigationView,Floating labels for editing text,Floating Action But 阅读详情

项目需要，现在需要把主页换成GridView和底部菜单栏组合的形式，但是这和当初设计的有点出入，代码全部使用Activity写的。现在有很多好用的底部菜单栏的控件，但是基本都是嵌套Fragment。后来想到用TabHost嵌套Activity来实现底部菜单栏的功能。接下来，我们开始吧~

效果图：

新建Home页，取名HomeActivity，在这里来组合TabHost和Activity，直接看代码吧：

注释：

HomeActivity ：父Activity

IndexActivity：子Activity

DailyCheckUploadForIndexActivity：子Activity

DailyThingsUploadForIndexActivity：子Activity

TaskMainForIndexActivity：子Activity

SystemSettingForIndexActivity：子Activity

1、

public class HomeActivity extends TabActivity {//如果子Activity中有startActivityForResult,需要继承TabActivity；否则不需要
//用于添加每一个选项卡的id
private String[] tags = {"A_tag", "B_tag", "C_tag", "D_tag", "E_tag"};
//所添加选项卡的文本信息
private String[] titles = {"主页", "上报病害", "上报事项", "工作任务", "系统设置"};
//所添加选项卡的图片信息
private int[] images = {R.drawable.bottom_zhuye_gray, R.drawable.bottom_shangbaobinghai_gray,
R.drawable.bottom_shangbaoshixiang_gray, R.drawable.bottom_gongzuorenwu_gray, R.drawable.bottom_setting_gray};
//用于跳转至不同的Activity
private Intent[] intents = new Intent[5];
TextView tv_1;
TextView tv_2;
TextView tv_3;
TextView tv_4;
TextView tv_5;
ImageView iv_1;
ImageView iv_2;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home_layout);
final TabHost tabHost = getTabHost();
TabWidget tabWidget = getTabWidget();
tabWidget.setBackgroundColor(Color.WHITE);
//坑人，下面LocalActivityManager没必要加，否则和调用getLocalActivityManager().getCurrentActivity()冲突，返回 //值总为空
//初始化activity管理者
// LocalActivityManager manager = new LocalActivityManager(HomeActivity.this, false);
//通过管理者保存当前页面状态
// manager.dispatchCreate(savedInstanceState);
//将管理者类对象添加至TabHost
// tabHost.setup(manager);
tabHost.setup();
init_intent();
for (int i = 0; i < intents.length; i++) {
//加载底部导航栏布局
LayoutInflater inflater = this.getLayoutInflater();
View view = inflater.inflate(R.layout.tab, null);
TextView textView = (TextView) view.findViewById(R.id.tv_item);
ImageView imageView = (ImageView) view.findViewById(R.id.image);
textView.setText(titles[i]);
imageView.setImageResource(images[i]);
//创建选项卡
TabHost.TabSpec spec = tabHost.newTabSpec(tags[i]);
spec.setIndicator(view);
//设置每个页面的内容
spec.setContent(intents[i]);
//将创建的选项卡添加至tabHost上
tabHost.addTab(spec);
}

// tabHost.setCurrentTab(2);

//获取每个子菜单中的控件，用于菜单颜色的改变

//每个页面放置的Activity

public void init_intent() {

//Intent添加 addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)，每次切换底部菜单时会重新加载Activity

Intent intent_0 = new Intent(this, IndexActivity.class);
intent_0.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);//addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)
Intent intent_1 = new Intent(this, DailyCheckUploadForIndexActivity.class);
intent_1.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
Intent intent_2 = new Intent(this, DailyThingsUploadForIndexActivity.class);
intent_2.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
Intent intent_3 = new Intent(this, TaskMainForIndexActivity.class);
intent_3.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
Intent intent_4 = new Intent(this, SystemSettingForIndexActivity.class);
intent_4.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intents[0] = intent_0;
intents[1] = intent_1;
intents[2] = intent_2;
intents[3] = intent_3;
intents[4] = intent_4;
}

//用于解决子Activity中onActivityResult()方法无效的情况
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
//获取当前活动的Activity实例
Activity subActivity = this.getLocalActivityManager().getCurrentActivity();
//判断是否实现返回值接口
if (subActivity instanceof OnTabActivityResultListener) {
//获取返回值实例接口
OnTabActivityResultListener listener = (OnTabActivityResultListener) subActivity;
//转发请求到子Activity
listener.onTabActivityResult(requestCode, resultCode, data);
}
super.onActivityResult(requestCode, resultCode, data);
}

/**
* 启动HomeActivity
*
* @param context 上下文
*/
public static void startActivity(Context context) {
Intent intent = new Intent();
intent.setClass(context, HomeActivity.class);
context.startActivity(intent);
}

}

2、HomeActivity 的布局文件

<?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:fitsSystemWindows="true"
android:orientation="vertical">
<TabHost
android:id="@android:id/tabhost"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" />

<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="@color/gray_pressed" />
<TabWidget
android:id="@android:id/tabs"
android:layout_width="match_parent"
android:layout_height="60dp" />
</LinearLayout>
</TabHost>

</LinearLayout>

3、tab布局

4、如果子Activity中没有startActivityForResult（）和onActivityResult（）方法，到这里就可以实现底部菜单栏了。

5、如果子Activity中有startActivityForResult（），接着往下看：

如果子Activity中startActivityForResult（）调用其他Activity时候遭遇到onActivityResult方法不响应

解决四步法：

a.通过父Activity启动其他Activity;

b.实现父Activity的onActivityResult方法,将该处接收到的请求转发给当前活动的子Activity;

c.自定义一个转发接口用来实现第2步中的转发功能;

d.子Activity中实现第3步接口中的方法用来接收返回信息;

代码：

a.通过父Activity启动其他Activity

getParent().startActivityForResult(new Intent(...), REQUEST_CODE);

b.实现父Activity的onActivityResult方法,将该处接收到的请求转发给当前活动的子Activity

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
//获取当前活动的Activity实例
Activity subActivity = this.getLocalActivityManager().getCurrentActivity();
//判断是否实现返回值接口
if (subActivity instanceof OnTabActivityResultListener) {
//获取返回值实例接口
OnTabActivityResultListener listener = (OnTabActivityResultListener) subActivity;
//转发请求到子Activity
listener.onTabActivityResult(requestCode, resultCode, data);
}
super.onActivityResult(requestCode, resultCode, data);

}

c.自定义一个转发接口用来实现第2步中的转发功能

public interface OnTabActivityResultListener {
public void onTabActivityResult(int requestCode, int resultCode, Intent data);

}

d.子Activity中实现第3步接口中的方法用来接收返回信息

@Override
public void onTabActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_CODE && resultCode == RESULT_OK) {
//实现该处逻辑
}
}

e.子Activity一定要实现implements OnTabActivityResultListener ,重写onTabActivityResult()

public void onTabActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
switch (requestCode) {
case SUB_REQUEST_CODE:
//Sub_History_visit();
break;

default:
break;
}
}
}

6、如果父Activity的onActivityResult（）方法中 getLocalActivityManager().getCurrentActivity()==null，检查父Activity 中是否有对LocalActivityManager 进行操作，有的话，删除或者注释。

到这里TabHost嵌套Activity的底部菜单栏就实现了
