将图标+文本添加到 TabLayout [英] Add Icons+Text to TabLayout

问题描述

我正在一个包含三个标签的屏幕上工作这是我的代码.

公共类 HomeScreen 扩展了 AppCompatActivity实现 NavigationView.OnNavigationItemSelectedListener {私人工具栏工具栏；私有 ViewPager 寻呼机；私有 ViewPagerAdapter 适配器；私人 SlidingTabLayout 选项卡；private CharSequence Titles[] = {"News", "Most Views", "Chart"};int Numboftabs = 3;@覆盖protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_home_screen);工具栏工具栏 = (工具栏) findViewById(R.id.toolbar);setSupportActionBar(工具栏);DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);ActionBarDrawerToggle 切换 = 新的 ActionBarDrawerToggle(这个，抽屉，工具栏，R.string.navigation_drawer_open，R.string.navigation_drawer_close)；drawer.setDrawerListener(toggle);切换.syncState();NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);navigationView.setNavigationItemSelectedListener(this);//马哈茂德代码添加//getSupportActionBar().setDisplayHomeAsUpEnabled(true);//getSupportActionBar().setIcon(R.drawable.ic_launcher);//创建 ViewPagerAdapter 并传递片段管理器、标题//选择选项卡和选项卡数量.适配器 = 新的 ViewPagerAdapter(getSupportFragmentManager(), Titles,Numboftabs);//分配 ViewPager 视图并设置适配器pager = (ViewPager) findViewById(R.id.pager);pager.setAdapter(适配器)；//分配滑动选项卡布局视图tabs = (SlidingTabLayout) findViewById(R.id.tabs);tabs.setDistributeEvenly(true);tabs.setViewPager(pager);}@覆盖公共无效 onBackPressed() {DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);如果 (drawer.isDrawerOpen(GravityCompat.START)) {drawer.closeDrawer(GravityCompat.START);} 别的 {super.onBackPressed();}}}

ViewPagerAdapter

public class ViewPagerAdapter extends FragmentStatePagerAdapter {字符序列标题[];int NumbOfTabs;公共 ViewPagerAdapter(FragmentManager fm, CharSequence mTitles[],int mNumbOfTabsumb) {超级(调频)；this.Titles = mTitles;this.NumbOfTabs = mNumbOfTabsumb;}//此方法返回 View Pager 中每个位置的片段@覆盖公共片段 getItem(int position) {开关(位置){案例0:返回新的 Tap1();情况1:返回新的 Tap2();案例2:返回新的 Tap3();}返回空；}//此方法返回选项卡条中选项卡的标题@覆盖公共 CharSequence getPageTitle(int position) {返回标题[位置];}//此方法返回选项卡条的选项卡数@覆盖公共 int getCount() {返回NumbOfTabs；}}

解决方案

试试这个，这正是你要找的

I am working on a screen which contains Three tabs I am trying to add an icon with My text in tabs and i want the image to be upper the text and there should be some space between them it is my code.

public class HomeScreen extends AppCompatActivity
    implements NavigationView.OnNavigationItemSelectedListener {

private Toolbar toolbar;
private ViewPager pager;
private ViewPagerAdapter adapter;
private SlidingTabLayout tabs;
private CharSequence Titles[] = {"News", "Most Views", "Chart"};
int Numboftabs = 3;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_home_screen);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
            this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
    drawer.setDrawerListener(toggle);
    toggle.syncState();

    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);

    //MAhmoud Code Addtion
    // getSupportActionBar().setDisplayHomeAsUpEnabled(true);
   // getSupportActionBar().setIcon(R.drawable.ic_launcher);

    // Creating The ViewPagerAdapter and Passing Fragment Manager, Titles
    // fot the Tabs and Number Of Tabs.
    adapter = new ViewPagerAdapter(getSupportFragmentManager(), Titles,
            Numboftabs);

    // Assigning ViewPager View and setting the adapter
    pager = (ViewPager) findViewById(R.id.pager);
    pager.setAdapter(adapter);

    // Assiging the Sliding Tab Layout View
    tabs = (SlidingTabLayout) findViewById(R.id.tabs);
    tabs.setDistributeEvenly(true);
    tabs.setViewPager(pager);

}

@Override
public void onBackPressed() {
    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    if (drawer.isDrawerOpen(GravityCompat.START)) {
        drawer.closeDrawer(GravityCompat.START);
    } else {
        super.onBackPressed();
    }
}}

ViewPagerAdapter

public class ViewPagerAdapter extends FragmentStatePagerAdapter {

CharSequence Titles[];
int NumbOfTabs;

public ViewPagerAdapter(FragmentManager fm, CharSequence mTitles[],
        int mNumbOfTabsumb) {
    super(fm);
    this.Titles = mTitles;
    this.NumbOfTabs = mNumbOfTabsumb;
}
// This method return the fragment for the every position in the View Pager
@Override
public Fragment getItem(int position) {
    switch (position) {
    case 0:
        return new Tap1();

    case 1:
        return new Tap2();
    case 2:
        return new Tap3();
    }
    return null;
}
// This method return the titles for the Tabs in the Tab Strip
@Override
public CharSequence getPageTitle(int position) {
    return Titles[position];
}
// This method return the Number of tabs for the tabs Strip
@Override
public int getCount() {
    return NumbOfTabs;
}}

public class MainActivity extends AppCompatActivity {

    private Toolbar toolbar;
    private TabLayout tabLayout;
    private ViewPager viewPager;
    private int[] tabIcons = {
            R.drawable.ic_tab_favourite,
            R.drawable.ic_tab_call,
            R.drawable.ic_tab_contacts

        toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);

        viewPager = (ViewPager) findViewById(R.id.viewpager);
        setupViewPager(viewPager);

        tabLayout = (TabLayout) findViewById(R.id.tabs);
        tabLayout.setupWithViewPager(viewPager);
        setupTabIcons();
    }

    private void setupTabIcons() {
        tabLayout.getTabAt(0).setIcon(tabIcons[0]);
        tabLayout.getTabAt(1).setIcon(tabIcons[1]);

    private void setupViewPager(ViewPager viewPager) {
        ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
        adapter.addFrag(new OneFragment(), "ONE");
        adapter.addFrag(new TwoFragment(), "TWO");
        adapter.addFrag(new ThreeFragment(), "THREE");
        viewPager.setAdapter(adapter);
    }

    class ViewPagerAdapter extends FragmentPagerAdapter {
        private final List<Fragment> mFragmentList = new ArrayList<>();
