ActionBar选项卡根据屏幕宽度设置动态宽度

我总共有五个标签。这就是我添加它们的方式:

for (int i = 0; i < tabs.length; i++) {

                if (i == 0) {
                    actionBar.addTab(
                            actionBar.newTab()
                                    .setText(null)
                                    .setIcon(R.drawable.activity)
                                    .setTabListener(this));
                } else if (i == 1) {
                    actionBar.addTab(
                            actionBar.newTab()
                                    .setText(null)
                                    .setIcon(R.drawable.group)
                                    .setTabListener(this));
                } else if (i == 2) {
                    actionBar.addTab(
                            actionBar.newTab()
                                    .setText(null)
                                    .setIcon(R.drawable.message)
                                    .setTabListener(this));
                } else if(i == 3){
                    actionBar.addTab(
                            actionBar.newTab()
                                    .setText(null)
                                    .setIcon(R.drawable.notification)
                                    .setTabListener(this));
                }
                else
                {
                    actionBar.addTab(
                            actionBar.newTab()
                                    .setText(null)
                                    .setIcon(R.drawable.hamburger)
                                    .setTabListener(this));
                }  

我尝试了this解决方案,但这会设置标签图标的宽度,而不是标签本身。

以下是我应用的样式:

应用主题

<style name="CustomActionBarTheme" parent="Theme.AppCompat.Light">
        <item name="android:windowActionBarOverlay">true</item>
        <item name="android:actionBarTabStyle">@style/actionBarTabBarStyle</item>
        <item name="android:actionBarStyle">@style/MyActionBar</item>
    </style>  

 <style name="actionBarTabBarStyle" parent="@style/Widget.AppCompat.ActionBar.TabView">
        <item name="android:paddingLeft">1dp</item>
        <item name="android:paddingRight">1dp</item>
        <item name="android:minWidth">10dp</item>
        <item name="android:maxWidth">15dp</item>
        <item name="android:showDividers">none</item>
    </style>  

我也尝试使用 customView 作为标签,但它没有用。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/tabItemLayout"
    android:gravity="center"
    android:layout_width="wrap_content" android:layout_height="match_parent">

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:adjustViewBounds="true"
        android:id="@+id/imageViewTab" />
</LinearLayout>

标签太宽,tabBar正在滑动。如何根据屏幕宽度使标签采用动态宽度而不产生滑动效果。即所有标签应适合屏幕宽度,宽度应相等。

这里有4个标签。 tabBar 是可滚动的,因此第五个标签会在滚动时出现,我不想要。

Tab视图宽度基于内容/ yourImage大小,因此要使标签视图宽度更小,我们必须控制内容/图像大小。您可以将ImageView置于FrameLayout内,例如您的customView可以是:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:id="@+id/tabItemLayout"
   android:gravity="center"
   android:layout_width="wrap_content" android:layout_height="match_parent">

   <FrameLayout
      android:layout_width="48dp"
      android:layout_height="48dp"
      android:layout_centerInParent="true"
      >

    <ImageView
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:adjustViewBounds="true"
      android:layout_gravity="center"
      android:gravity="center"
      android:id="@+id/imageViewTab" />

   </FrameLayout> 

</RelativeLayout>

和标签的自定义样式:

<style name="AppTheme" parent="@style/Theme.AppCompat.Light">

             ... ...
    <item name="actionBarTabStyle">@style/ActionBarTabStyle</item>

</style>

<style name="ActionBarTabStyle" parent="@style/Widget.AppCompat.Base.ActionBar.TabView">
   <item name="android:paddingLeft">0dp</item>
   <item name="android:paddingRight">0dp</item>
   <item name="android:paddingTop">0dp</item>
   <item name="android:paddingBottom">0dp</item>
</style>

当您尝试在适合设备宽度的Actionbar上实现标签时,可以使用PagerSlidingTabStripSlidingTabLayout,这样可以更灵活地实现标签及其相关片段{{1这使得你的Uix更有效率和用户友好的触摸。

我在这里展示如何使用ViewPager

来实现它

使用以下代码更改选项卡的大小并使选项卡适合屏幕宽度。确保您使用的是自定义视图

DisplayMetrics displaymetrics = new DisplayMetrics();
           getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
           int screenWidth = displaymetrics.widthPixels;          
           final View tabView = actionBar.getTabAt(0).getCustomView();
           final View tabContainerView = (View) tabView.getParent();
           final int tabPadding = tabContainerView.getPaddingLeft() + tabContainerView.getPaddingRight();
           final int tabs = actionBar.getTabCount();
           for(int i=0 ; i < tabs ; i++) {
               View tab = actionBar.getTabAt(i).getCustomView();
          LinearLayout tabItemLayout = (LinearLayout) tab.findViewById(R.id.tabItemLayout);
          tabItemLayout.setLayoutParams(new LayoutParams(screenWidth/tabs-tabPadding-1, LayoutParams.WRAP_CONTENT));
          }
