Question

您好我在我的活动中创建了一个标签布局。这是主要的 .xml 文件：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    android:id="@+id/main_layout"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.xxxxxx.eventmanager.EventDetailsActivity">

    <android.support.design.widget.AppBarLayout
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        android:id="@+id/toolbarContainer"
        android:theme="@style/AppTheme.AppBarOverlay">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_alignParentTop="true"
            android:background="?attr/colorPrimary"
            android:elevation="6dp"
            android:minHeight="?attr/actionBarSize"
            app:popupTheme="@style/AppTheme.PopupOverlay" />

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

    <android.support.design.widget.TabLayout
        android:id="@+id/tab_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/toolbarContainer"
        android:background="?attr/colorPrimary"
        android:elevation="6dp"
        android:minHeight="?attr/actionBarSize"
        app:tabTextColor="@color/colorLight"
        app:tabSelectedTextColor="@color/colorAccent"
        android:textAlignment=""
        android:theme="@style/AppTheme"/>

    <android.support.v4.view.ViewPager
        android:id="@+id/pager"
        android:layout_width="match_parent"
        android:layout_height="fill_parent"
        android:layout_below="@id/tab_layout"/>

</RelativeLayout>

这是我的 .java 类：

package com.xxxxxx.eventmanager;

import android.graphics.drawable.Drawable;
import android.support.design.widget.TabLayout;
import android.support.v13.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;

import com.xxxxxx.eventmanager.adapters.EventPagerAdapter;

public class EventDetailsActivity extends AppCompatActivity  {

    /**
     * The {@link android.support.v4.view.PagerAdapter} that will provide
     * fragments for each of the sections. We use a
     * {@link FragmentPagerAdapter} derivative, which will keep every
     * loaded fragment in memory. If this becomes too memory intensive, it
     * may be best to switch to a
     * {@link android.support.v13.app.FragmentStatePagerAdapter}.
     *
     * private SectionsPagerAdapter mSectionsPagerAdapter;
     *
     */

    private Toolbar toolbar;

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

        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);
        tabLayout.addTab(tabLayout.newTab().setText("Details").setIcon(R.mipmap.ic_details));
        tabLayout.addTab(tabLayout.newTab().setText("Sales").setIcon(R.mipmap.ic_sales));
        tabLayout.addTab(tabLayout.newTab().setText("Purchases").setIcon(R.mipmap.ic_purchase));
        tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);

        final ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
        final EventPagerAdapter adapter = new EventPagerAdapter
                (getSupportFragmentManager(), tabLayout.getTabCount());
        viewPager.setAdapter(adapter);
        viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
        tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
            @Override
            public void onTabSelected(TabLayout.Tab tab) {
                viewPager.setCurrentItem(tab.getPosition());
            }

            @Override
            public void onTabUnselected(TabLayout.Tab tab) {

            }

            @Override
            public void onTabReselected(TabLayout.Tab tab) {

            }
        });

    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_event_details, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }

}

现在，标签显示如下：

但是现在我希望图标显示在文本的左侧而不是文本的顶部。

@Tjerkw给出的答案是好的，只是它没有遍历整个标签。我想正确的解决方案应该是这个

for (int i = 0; i < tabLayout.getTabCount(); i++ ) {
     yourlinearlayout = (LinearLayout) LayoutInflater.from(getContext()).inflate(R.layout.title_text, null);
     tab_text = (TextView) yourlinearlayout.findViewById(R.id.tabContent);
            tab_text.setText("  " + tab_titles[i]);
     tab_text.setCompoundDrawablesWithIntrinsicBounds(tabicons[i], 0, 0, 0);
        tabLayout.getTabAt(i).setCustomView(tab_text);}

，代表R.layout.title_text的布局资源.xml将为

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
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/white"
    android:gravity="center"/>

最后，tabicons[i]和tab tab_titles[i]只是包含各自内容的String数组。我知道这个问题很老，但我最近遇到了这个问题，我确信其他人可能还需要这个

Answer 2

TabLayout还支持自定义视图而不是TabView。

1.创建标签项目布局。主要思想是我们应该使用指定ID 对于ImageView @android：id / icon 和TextView @android：id / text1

<强> R.layout.custom_tab_item

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@color/color_app_background"
    android:gravity="center"
    android:orientation="horizontal">

    <ImageView
        android:id="@android:id/icon"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:src="@drawable/appoinments_" />

    <com.app.barber.views.CustomTextView
        android:id="@android:id/text1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:gravity="center"
        android:paddingBottom="@dimen/_8sdp"
        android:paddingLeft="@dimen/_5sdp"
        android:paddingTop="@dimen/_8sdp"
        android:text="@string/title_appointments"
        android:textColor="@color/color_white"
        android:textSize="@dimen/_12ssp" />
</LinearLayout>

<强> 2。和TabLayout xml文件

 <android.support.design.widget.TabLayout
      xmlns:app="http://schemas.android.com/apk/res-auto"
      android:id="@+id/tab_layout"
      android:layout_width="match_parent"
      android:layout_height="?attr/actionBarSize"
      android:background="?attr/colorPrimary"
      app:tabMaxWidth="0dp"
      app:tabGravity="fill"
      app:tabMode="fixed"
      android:theme="@style/vocabularyTheme.ActionBar" />

第3。使用自定义视图创建tabLayout，并删除底部边距，默认设置为8dp

mTabLayout = (TabLayout) findViewById(R.id.tab_layout);     
mTabLayout.addTab(createTab(text1,icon1));
mTabLayout.addTab(createTab(text2,icon2));

private TabLayout.Tab createTab(String text, Drawable icon){
    TabLayout.Tab tab = mTabLayout.newTab().setText(text).setIcon(icon).setCustomView(R.layout.custom_tab_item);

    // remove imageView bottom margin
    if (tab.getCustomView() != null){
        ImageView imageView = (ImageView) tab.getCustomView().findViewById(android.R.id.icon);
        ViewGroup.MarginLayoutParams lp = ((ViewGroup.MarginLayoutParams) imageView.getLayoutParams());
        lp.bottomMargin = 0;
        imageView.requestLayout();
    }

    return tab;
}

预期结果。

Answer 3

我有你们想要的确切解决方案。

<android.support.design.widget.TabLayout
    android:id="@+id/tabLayout"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:textAlignment="textStart"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:tabInlineLabel="true"
    app:tabPaddingStart="@dimen/default_10dp">

使用下面的属性可以达到期望的结果。

app：tabInlineLabel =“ true”

Answer 4

只需将此行添加到XML的TabLayout中

app:tabInlineLabel="true"

Answer 5

使用自定义视图：

TextView newTab = (TextView) LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
newTab.setText("tab1"); //tab label txt
newTab.setCompoundDrawablesWithIntrinsicBounds(your_drawable_icon_here, 0, 0, 0);
tabLayout.getTabAt(tab_index_here_).setCustomView(newTab);

Answer 6

您必须在ActionMenuView内引入Toolbar。

从Google Official docs “ActionMenuView是一系列菜单选项的视图。它提供了几个顶级选项作为操作按钮，同时将剩余选项作为溢出菜单中的项目溢出这允许应用程序以特定或重复内容的形式呈现动作包。“

例如，

<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/tToolbar"
    android:layout_height="?attr/actionBarSize"
    android:layout_width="match_parent"
    android:background="?attr/colorPrimary"
    android:gravity="center_vertical|start"
    app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light">

    <android.support.v7.widget.ActionMenuView
        android:id="@+id/amvMenu"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"/>
</android.support.v7.widget.Toolbar>

关于你的活动，

Toolbar t = (Toolbar) findViewById(R.id.tToolbar);
    amvMenu = (ActionMenuView) t.findViewById(R.id.amvMenu);
    amvMenu.setOnMenuItemClickListener(new ActionMenuView.OnMenuItemClickListener() {
      @Override
      public boolean onMenuItemClick(MenuItem menuItem) {
        return onOptionsItemSelected(menuItem);
      }
    });

将选项卡布局中的图标对齐到左侧
