TabLayout的选项卡之间的分隔线以编程方式LinearLayout.SHOW_DIVIDER_MIDDLE [英] Divider between Tabs of TabLayout Programatically LinearLayout.SHOW_DIVIDER_MIDDLE
问题描述
我尝试在制表符之间添加分隔符,而不使用任何自定义布局.我已经使用以下方法以编程方式对其进行了尝试:
I've tried adding the divider between tabs, without using any custom layout. I have tried it programmatically using the following method:
public static void addTabsDividers(TabLayout tabLayout, @ColorRes int divColorRes,int divWidthDP,int divHeightDP){
View root = tabLayout.getChildAt(0);
if (root instanceof LinearLayout) {
((LinearLayout) root).setShowDividers(LinearLayout.SHOW_DIVIDER_MIDDLE);
GradientDrawable drawable = new GradientDrawable();
drawable.setColor(tabLayout.getContext().getResources().getColor(divColorRes));
drawable.setSize(divWidthDP, divHeightDP);
// ((LinearLayout) root).setDividerPadding(10);
((LinearLayout) root).setDividerDrawable(drawable);
}
}
,但这会在标签的左侧添加额外的空间:
but this adds extra space in left side of tabs:
请注意标签左侧的奇怪空白,我想删除它!
Notice the strange white space on left side of tabs, I want to remove that !!

推荐答案
我在您使用的同一问题上看到您,并且您使用的解决方案与我相同,并且我遇到了同样的问题!但是我发现为分隔线使用自定义可绘制对象100%解决了该问题,现在我在两个选项卡的中间只有一个分隔线.这是我正在使用的可绘制对象:
I saw you on the same question I was using and you are using the same solution as me and I have the same issue! But I found out using a custom drawable for the divider 100% solved the problem and now I only have a divider in the middle of my two tabs. This is the drawable I was using:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<size android:width="1dp" />
<solid android:color="@android:color/white" />
</shape>
</item>
<item
android:bottom="16dp"
android:top="12dp">
<shape android:shape="rectangle">
<solid android:color="@color/color_gray" />
<size android:width="1dp" />
</shape>
</item>
让我知道这是否对您有用.
let me know if this works for you.
public class MyTabLayout extends TabLayout {
public MyTabLayout(Context context) {
super(context);
}
public MyTabLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}
public MyTabLayout(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
/**
* Adds vertical dividers between tabs
*/
public void addTabDivider() {
LinearLayout linearLayout = (LinearLayout)getChildAt(0);
linearLayout
.setShowDividers(LinearLayout.SHOW_DIVIDER_MIDDLE);
Drawable drawable = MyApp.getInstance().getDrawable(R.drawable.tab_divider);
linearLayout.setDividerDrawable(drawable);
}
