Android选项卡布局不占用自定义视图的全宽 [英] Android Tab Layout not taking up full width with custom view

问题描述

未删除的Android TabLayout tabPaddingTop和tabPaddingBottom

请同时参考上述问题.

自从我将设计库更新为"23.2.0"以来，Tab布局就一团糟.

下面的图片是我的标签页布局.

Xml部分:-

<android.support.design.widget.TabLayout
    android:id="@+id/sliding_tabs"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:tabIndicatorColor="@android:color/white"
    app:tabIndicatorHeight="@dimen/dp2"
    app:tabMode="fixed"
    app:tabSelectedTextColor="@android:color/white"
    app:tabTextAppearance="@style/MyCustomTabTextAppearance" />

样式xml:-

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/color_156084</item>
</style>

<style name="MyCustomTabTextAppearance" parent="TextAppearance.Design.Tab">
    <item name="android:textSize">@dimen/sp14</item>
    <item name="android:textColor">@android:color/white</item>
    <item name="textAllCaps">false</item>
</style>

我已经将padding设置为-1dp，甚至没有填满tabGravity，但没有任何效果.

此代码以前可以在早期版本中运行，但是现在如果我对其进行降级，则会在TintManager上收到找不到类定义的错误.

解决方案

设置不同的值或布局参数无效，因此，在将选项卡添加到选项卡布局后，我得到的唯一解决方案是添加以下内容，

final ViewGroup test = (ViewGroup)(tabs.getChildAt(0));//tabs is your Tablayout
int tabLen = test.getChildCount();

for (int i = 0; i < tabLen; i++) {
            View v = test.getChildAt(i);
            v.setPadding(0, 0, 0, 0);
        }

Android TabLayout tabPaddingTop and tabPaddingBottom not being removed

Please refer to the above issue as well.

Even since i updated my design library to "23.2.0", Tab layout is all messed up.

The below image is my Tab Layout.

Xml Part :-

<android.support.design.widget.TabLayout
    android:id="@+id/sliding_tabs"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:tabIndicatorColor="@android:color/white"
    app:tabIndicatorHeight="@dimen/dp2"
    app:tabMode="fixed"
    app:tabSelectedTextColor="@android:color/white"
    app:tabTextAppearance="@style/MyCustomTabTextAppearance" />

styles xml :-

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/color_156084</item>
</style>

<style name="MyCustomTabTextAppearance" parent="TextAppearance.Design.Tab">
    <item name="android:textSize">@dimen/sp14</item>
    <item name="android:textColor">@android:color/white</item>
    <item name="textAllCaps">false</item>
</style>

I have set padding to -1dp and even did tabGravity to fill but nothing is working.

This code used to work in earlier versions but now if i am downgrading it, i am getting a no class def found error on TintManager.

解决方案

Setting different values or layout params did not work, so the only solution I got was to add the following, after you add the tabs to your tab layout,

final ViewGroup test = (ViewGroup)(tabs.getChildAt(0));//tabs is your Tablayout
int tabLen = test.getChildCount();

for (int i = 0; i < tabLen; i++) {
            View v = test.getChildAt(i);
            v.setPadding(0, 0, 0, 0);
        }
