FragmentTabHost实现底部导航栏

第一步：布局文件activity_main.xml

第二步：新建布局文件tab_item_view.xml

    



第三步：添加选中与未选中的样式

在drawable新建selector.xml文件

选中状态，新建isselector.xml

未选中状态，新建unselector.xml

第四步：新建fragment_1.xml文件需要几个新建几个

第五步：新建类文件继承Fragment（android.support.v4.app）需要几个新建几个

public class FragmentPage1 extends Fragment {
    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {
        return inflater.inflate(R.layout.fragment_1,null);
    }

    @Override
    public void onActivityCreated(@Nullable Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);

    }
}

第六步：MainActivity中代码

public class MainActivity extends AppCompatActivity {
    private FrameLayout frameLayout;
    private LayoutInflater layoutInflater;
    private FragmentTabHost tabHost;
    private Context context;
    private Class fragmentArray[] = {FragmentPage1.class,FragmentPage2.class,FragmentPage3.class,FragmentPage4.class,FragmentPage5.class};
    private String textViewArray[] = {"直播","动画片","电影","音乐","我的"};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        context = this;
        layoutInflater = LayoutInflater.from(context);
        tabHost = findViewById(R.id.tabHost);
        tabHost.setup(context,getSupportFragmentManager(),R.id.realtabcontent);
        for(int i = 0;i
