将图标+文本添加到TabLayout

Question

我正在制作一个包含三个标签的屏幕我试图在标签中添加一个带有我的文字的图标，我希望图像位于文本的上方，它们之间应该有一些空格 这是我的代码。

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;
}}

Answer 1

尝试这种方式，这正是您所寻找的

http://www.androidhive.info/2015/09/android-material-design-working-with-tabs/

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
    };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        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]);
        tabLayout.getTabAt(2).setIcon(tabIcons[2]);
    }

    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<>();
        private final List<String> mFragmentTitleList = new ArrayList<>();

        public ViewPagerAdapter(FragmentManager manager) {
            super(manager);
        }

        @Override
        public Fragment getItem(int position) {
            return mFragmentList.get(position);
        }

        @Override
        public int getCount() {
            return mFragmentList.size();
        }

        public void addFrag(Fragment fragment, String title) {
            mFragmentList.add(fragment);
            mFragmentTitleList.add(title);
        }

        @Override
        public CharSequence getPageTitle(int position) {
            return mFragmentTitleList.get(position);
        }
    }
}

首先创建一个布局xml文件，该文件具有所需的选项卡结构 例如，文本顶部的简单图标。像这样：

1。在layout文件夹＆gt;中创建导航标签布局xml： nav_tab.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/nav_tab"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:gravity="center_horizontal">

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="@dimen/nav_icon"
        android:scaleType="centerInside"
        android:id="@+id/nav_icon"
        android:layout_marginBottom="@dimen/tiny_padding"/>

    <TextView
        android:id="@+id/nav_label"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:fontFamily="@string/font_fontFamily_medium"
        android:shadowColor="@android:color/black"
        android:textColor="@color/dark_grey"
        android:textSize="@dimen/nav_tab_label_font_size"
        tools:text="@string/nav_home" />

</LinearLayout>

将您的布局和ID设置为膨胀，并在给父布局充气后再提供ImageView和TextView ID以供稍后参考。

2。在drawable文件夹中定义图标，在strings.xml文件

中标记

并按照您希望图标显示的数组中的资源ID引用它们：

private int[] navIcons = {
        R.drawable.ico_home,
        R.drawable.ico_search,
        R.drawable.ico_notification,
        R.drawable.ico_profile
};
private int[] navLabels = {
        R.string.nav_home,
        R.string.nav_search,
        R.string.nav_notifications,
        R.string.nav_profile
};
// another resouces array for active state for the icon
private int[] navIconsActive = {
        R.drawable.ico_home_red,
        R.drawable.ico_search_red,
        R.drawable.ico_notification_red,
        R.drawable.ico_profile_red
};

3。使用TabLayout：

设置ViewerPager

TabLayout navigation = (TabLayout) findViewById(R.id.navigation);
navigation.setupWithViewPager(mainView/* the viewer pager object*/);

现在定制部分：

// loop through all navigation tabs
for (int i = 0; i < navigation.getTabCount(); i++) {
    // inflate the Parent LinearLayout Container for the tab
    // from the layout nav_tab.xml file that we created 'R.layout.nav_tab
    LinearLayout tab = (LinearLayout) LayoutInflater.from(this).inflate(R.layout.nav_tab, null);

    // get child TextView and ImageView from this layout for the icon and label
    TextView tab_label = (TextView) tab.findViewById(R.id.nav_label);
    ImageView tab_icon = (ImageView) tab.findViewById(R.id.nav_icon);

    // set the label text by getting the actual string value by its id
    // by getting the actual resource value `getResources().getString(string_id)`
    tab_label.setText(getResources().getString(navLabels[i]));

    // set the home to be active at first
    if(i == 0) {
        tab_label.setTextColor(getResources().getColor(R.color.efent_color));
        tab_icon.setImageResource(navIconsActive[i]);
    } else {
        tab_icon.setImageResource(navIcons[i]);
    }

    // finally publish this custom view to navigation tab
    navigation.getTabAt(i).setCustomView(tab);
}

设置活动状态的最终触摸，并在选中选项卡时更改图标和文本颜色：

如果您想在图块布局中将图标和文字放在一行中，则必须按照以下方式制作自定义布局。

<强> custom_tab_heading.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"
    android:gravity="center">
    <TextView
        android:id="@+id/tabContent"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:textAlignment="center"
        android:textColor="@android:color/black"
        android:gravity="center"/>
</LinearLayout>

在您的Java端，您可以在下面写下代码，将图像和标题放到标签中。

val tabTitles = arrayListOf<String>("  Text Jokes","  Funny Images")
val tabIcons = arrayListOf<Int>(R.drawable.text_jokes,R.drawable.image_jokes)


val tabLinearLayout = LayoutInflater.from(context).inflate(R.layout.custom_tab_heading, null) as LinearLayout
val tabContent = tabLinearLayout.findViewById<View>(R.id.tabContent) as TextView
tabContent.text = tabTitles.get(0)
tabContent.setCompoundDrawablesWithIntrinsicBounds(tabIcons[0], 0, 0, 0)
myTabLayout.getTabAt(0)!!.setCustomView(tabContent)

val tabLinearLayout1 = LayoutInflater.from(context).inflate(R.layout.custom_tab_heading, null) as LinearLayout
val tabContent1 = tabLinearLayout1.findViewById<View>(R.id.tabContent) as TextView
tabContent1.text = tabTitles.get(1)
tabContent1.setCompoundDrawablesWithIntrinsicBounds(tabIcons[1], 0, 0, 0)
var l = tabLinearLayout1.layoutParams
myTabLayout.getTabAt(1)!!.setCustomView(tabContent1)

注意： - 在tabTitles数组中，请注意我在文本（<space>Title 1）之前给出了空格，因为它会在图像和标题之间留出空格。

很抱歉我在这里提供kotlin代码，但您可以轻松将其转换为java。如果有人有问题，请在这个答案中发表评论，我会尽力帮助他们。
