在选项卡自定义布局中,我将其父元素设置为match_parent并设置其背景颜色。当我运行它时,会显示包含元素 imageview 和 textview 的自定义布局。我希望这个自定义布局将填充选项卡,选项卡之间没有任何空格。在此处检查输出:选项卡截图

private void setupTabLayout(ViewPager viewPager, ViewPagerAdapter viewPagerAdapter) {
    TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);
    tabLayout.setupWithViewPager(viewPager);

    int length = tabLayout.getTabCount();
    for (int i = 0; i < length; i++) {
        tabLayout.getTabAt(i).setCustomView(viewPagerAdapter.getTabView(i));
    }
}

tab_layout.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/layout"
    android:background="@color/grey_accent">

    <ImageView
        android:layout_gravity="center"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/icon"
        android:src="@drawable/ic_action_home"
        android:layout_marginBottom="19dp"
        android:layout_above="@+id/title"
        android:layout_centerHorizontal="true" />

    <TextView
        android:layout_gravity="center"
        android:textColor="@color/white"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Home"
        android:id="@+id/title"
        android:layout_marginBottom="259dp"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true" />
</RelativeLayout>

ViewPagerAdapter:

public View getTabView(int position) {
    View view = LayoutInflater.from(this.context).inflate(R.layout.tab_layout, null);
    TextView title = (TextView) view.findViewById(R.id.title);
    ImageView icon = (ImageView) view.findViewById(R.id.icon);
    ViewGroup layout = (ViewGroup) view.findViewById(R.id.layout);

    layout.setBackgroundResource(this.mColorList.get(position));
    icon.setImageResource(this.mIconList.get(position));
    title.setText(this.getPageTitle(position));

    return view;
}

尝试这个

<android.support.design.widget.TabLayout
    app:tabPaddingStart="-1dp"
    app:tabPaddingEnd="-1dp"/>

我在这里找到了

您可以使用材料设计选项卡布局,然后为所有选项卡提供自定义视图。如需完整参考,请访问:自定义 Tablayout 示例

所有选项卡的自定义视图可以是这样的:

<?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:gravity="center"
    android:orientation="vertical">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:id="@+id/ll"
        android:orientation="horizontal"
        android:layout_weight="1"
        android:gravity="center">

        <ImageView
            android:layout_width="30dp"
            android:layout_height="30dp"
            android:src="@mipmap/ic_launcher"/>
        <TextView
            android:id="@+id/tvtab1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="ONE"
            android:textColor="@color/colorAccent"
            android:textSize="14sp"
            android:textStyle="bold" />
    </LinearLayout>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:id="@+id/ll2"
        android:orientation="vertical"
        android:gravity="center">
        <ImageView
            android:layout_width="30dp"
            android:layout_height="30dp"
            android:src="@mipmap/ic_launcher"/>

        <TextView
            android:id="@+id/tvtab2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="TWO"
            android:textColor="#26e9dc"
            android:textSize="14sp"
            android:textStyle="bold" />
    </LinearLayout>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:id="@+id/ll3"
        android:orientation="vertical"
        android:gravity="center">

        <TextView
            android:id="@+id/tvtab3"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="THREE"
            android:textColor="#d8ea2b"
            android:textSize="14sp"
            android:textStyle="bold" />
        <ImageView
            android:layout_width="30dp"
            android:layout_height="30dp"
            android:src="@mipmap/ic_launcher"/>
    </LinearLayout>
</LinearLayout>

活动 xml 文件的代码 (activity_main.xml)

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

        <android.support.design.widget.TabLayout
            android:id="@+id/tabs"
            android:layout_width="match_parent"

        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior" />

</android.support.design.widget.CoordinatorLayout>

MainActivity.java的最后代码

添加多个选项卡

第 1 步:为 customtabs 添加 xml 布局代码

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentBottom="true">
<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:layout_scrollFlags="scroll|enterAlways"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

    <android.support.design.widget.TabLayout
        android:id="@+id/tabs"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:tabMode="scrollable"
        android:background="@color/white"
        app:tabGravity="center" />

</android.support.design.widget.AppBarLayout>


<android.support.v4.view.ViewPager
    android:id="@+id/viewpager"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    android:layout_marginBottom="50dp"/>

第 2 步:标签活动的 Java 代码

public class BookingsTabs extends AppCompatActivity {
    String url, smobile, snames, semail, sid, stoken, responseServer;
    String id, token, did, stsid, processresponse, type, cancelresponse;
    TextView tv1;
    Button cretedeal;
    ViewbookingsAdapter adapter;
    ViewbookingsAdapter2 adapter2;
    LinearLayout order;
    private Tracker mTracker;
    ProgressDialog pDialog;
    ListView listview;
    private Toolbar toolbar;
    private TabLayout tabLayout;
    private ViewPager viewPager;
    AnalyticsApplication application1;
    SessionManagement session;

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

        toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        if (toolbar != null) {
            setSupportActionBar(toolbar);
            ActionBar actionBar = getSupportActionBar();
            actionBar.setDisplayHomeAsUpEnabled(true);
            actionBar.setDisplayShowHomeEnabled(true);
            actionBar.setDisplayShowTitleEnabled(true);
            actionBar.setDisplayUseLogoEnabled(false);
            actionBar.setHomeButtonEnabled(true);
        }

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
            getWindow().setStatusBarColor(getResources().getColor(R.color.colorPrimaryDark));
        }
        viewPager = (ViewPager) findViewById(R.id.viewpager);
        setupViewPager(viewPager);
        int defaultValue = 0;
        int page = getIntent().getIntExtra("TAB", defaultValue);
        viewPager.setCurrentItem(page);
        application1 = (AnalyticsApplication) getApplication();
        mTracker = application1.getDefaultTracker();
        tabLayout = (TabLayout) findViewById(R.id.tabs);
        tabLayout.setupWithViewPager(viewPager);
        tabLayout.setSelectedTabIndicatorColor(getResources().getColor(R.color.accentColor));
        tabLayout.setTabTextColors(ContextCompat.getColorStateList(this, R.color.aquablue));

        tabLayout.getTabAt(0).setCustomView(R.layout.aquablue);
        tabLayout.getTabAt(1).setCustomView(R.layout.orangeprocess);
        tabLayout.getTabAt(2).setCustomView(R.layout.shipping);
        tabLayout.getTabAt(3).setCustomView(R.layout.deliver);
        tabLayout.getTabAt(4).setCustomView(R.layout.completedtxt);
        tabLayout.getTabAt(5).setCustomView(R.layout.cancelled);

        callAsynchronousTask();
        viewPager.setCurrentItem(0);
    }

    private void setupViewPager(ViewPager viewPager) {
        ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
        adapter.addFrag(new OrderplacedFragment(), "Order Placed");
        adapter.addFrag(new ProcessingFragment(), "Processing");
        adapter.addFrag(new ShippingFragment(), "Shipping");
        adapter.addFrag(new DeliveredFragment(), "Delivered");
        adapter.addFrag(new CompletedFragment(), "Completed");
        adapter.addFrag(new CancelledFragment(), "Cancelled");
        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) {
            if (position == 0) {

            }
            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);
        }
    }
}

第 3 步:我在下面添加了一个与其他选项卡相同的选项卡的示例选项卡代码片段

获取 xml 代码任何列表视图或一些数据

public class OrderplacedFragment extends Fragment {
    View mMainView;
    String url, smobile, snames, semail, sid, stoken, responseServer;
    Context context;
    ViewbookingsAdapter adapter;
    ViewbookingsAdapter2 adapter2;
    ListView listview;
    LinearLayout tv1;
    TextView create;
    ArrayList<HashMap<String, String>> processlist, hatfilterslist;
    SessionManagement session;
    private SwipeRefreshLayout mSwipeRefreshLayout = null;

    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        mMainView = inflater.inflate(R.layout.listview_orderbookings, container, false);

        listview = (ListView) mMainView.findViewById(R.id.listview);

        pDialog = new ProgressDialog(getActivity());
        pDialog.setMessage("Loading...");
        pDialog.setMax(5);
        Intent j = getActivity().getIntent();
        coupon_code = j.getStringExtra("code");
        create = (TextView) mMainView.findViewById(R.id.dealslist);
        tv1 = (LinearLayout) mMainView.findViewById(R.id.no_deals_linear);
        create = (TextView) mMainView.findViewById(R.id.dealslist);
        create.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                Intent i = new Intent(getActivity(), MyDealsActivity.class);
                startActivity(i);

            }
        });
        tv1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                Intent i = new Intent(getActivity(), MyDealsActivity.class);
                startActivity(i);
            }
        });

        return mMainView;
    }
}

在此选项卡中,我们也可以添加计数。如果您对此有任何疑问,请咨询我

当您使用 时inflate(R.layout.tab_layout, null),您是在说根本没有父母View根据此专业提示,这会导致所有layout_属性都被丢弃。

相反,您应该传入TabLayoutand false(即,不要自动附加View):这样可以确保属性不会被忽略。

public View getTabView(TabLayout tabLayout, int position) {
    View view = LayoutInflater.from(this.context)
        .inflate(R.layout.tab_layout, tabLayout, false);
    TextView title = (TextView) view.findViewById(R.id.title);
    ImageView icon = (ImageView) view.findViewById(R.id.icon);
    ViewGroup layout = (ViewGroup) view.findViewById(R.id.layout);

    layout.setBackgroundResource(this.mColorList.get(position));
    icon.setImageResource(this.mIconList.get(position));
    title.setText(this.getPageTitle(position));

    return view;
}
