底部菜单实现(三)fragmentTabHost和fragment

一.FragmentTabHost的好处

在于可以更加灵活的设置按钮的样式.和轻易的与frgment切换进行绑定.节省了代码量

二.布局文件

主布局

<LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical"tools:context="com.example.tabhost.MainActivity"><FrameLayout    android:id="@+id/tabContent"    android:layout_width="match_parent"    android:layout_height="0dp"    android:layout_weight="1"></FrameLayout><android.support.v4.app.FragmentTabHost    android:id="@+id/tab"    android:layout_width="match_parent"    android:layout_height="wrap_content"></android.support.v4.app.FragmentTabHost></LinearLayout>    

tab标签的布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"          android:layout_width="wrap_content"          android:layout_height="wrap_content"          android:orientation="vertical"><TextView    android:id="@+id/tv"    android:layout_width="wrap_content"    android:layout_height="wrap_content"/><ImageView    android:id="@+id/iv"    android:layout_width="wrap_content"    android:layout_height="wrap_content"/></LinearLayout>   

三.代码

public class MainActivity extends AppCompatActivity {@Bind(R.id.framlayout)FrameLayout mFramlayout;@Bind(R.id.btn1)Button mBtn1;@Bind(R.id.btn2)Button mBtn2;@Bind(R.id.btn3)Button mBtn3;@Bind(R.id.radio_group)RadioGroup mRadioGroup;@Overrideprotected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_main);    ButterKnife.bind(this);    iniView();    iniEvent();}private void iniEvent() {    mRadioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {        @Override        public void onCheckedChanged(RadioGroup group, int checkedId) {            FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();            BaseFragment fragment = null;            switch (checkedId) {                case R.id.btn1:                    fragment = FragmentFractory.getInstance().getBaseFragment(0);                    break;                case R.id.btn2:                    fragment = FragmentFractory.getInstance().getBaseFragment(1);                    break;                case R.id.btn3:                    fragment = FragmentFractory.getInstance().getBaseFragment(2);                    break;            }            transaction.replace(R.id.framlayout, fragment).commit();        }    });}private void iniView() {    getSupportFragmentManager().            beginTransaction().            replace(R.id.framlayout, FragmentFractory.getInstance().getBaseFragment(0))            .commit();}

}

代码:

public class MainActivity extends AppCompatActivity {    private Class []clazz={Fragment1.class,Fragment2.class,Fragment3.class,Fragment4.class};    private FrameLayout mContainer;    private FragmentTabHost mTabHost;    String []tag={"one","two","three","four"};    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        mContainer = (FrameLayout) findViewById(R.id.container);        mTabHost = (FragmentTabHost) findViewById(R.id.tab);        iniTab();    }    private void iniTab() {        //初始化tabHOST标签        mTabHost.setup(this,getSupportFragmentManager(),R.id.container);        //给每一个标签关联frgemnt        for (int i = 0; i <tag.length ; i++) {            //给每一个标签添加标记            TabHost.TabSpec tabSpec = mTabHost.newTabSpec(tag[i]);            //拿到每一个标签的布局文件         View view =getView(i);            //关联标签的布局            tabSpec.setIndicator(view);            //把标签添加到FragmnetTabhost            mTabHost.addTab(tabSpec,clazz[i],null);        }    }    private View getView(int i) {        TextView text=new TextView(this);        switch (i) {            case 0:                text.setText("首页");                 break;            case 1:                text.setText("发现");                 break;            case 2:                text.setText("购物");                 break;            case 3:                text.setText("我的");                 break;        }        return text;    }}

布局文件

<LinearLayout    xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    tools:context="com.example.administrator.recovertabfragmenthost.MainActivity">    <FrameLayout        android:id="@+id/container"        android:layout_width="match_parent"        android:layout_height="0dp"        android:layout_weight="1"></FrameLayout>    <android.support.v4.app.FragmentTabHost        android:id="@+id/tab"        android:layout_width="match_parent"        android:layout_height="wrap_content"></android.support.v4.app.FragmentTabHost></LinearLayout>
