crysis21 / pagertabindicator Goto Github PK

I need to change tab text on page selection change, so for that i need listener to set updated text on page change. I don't know how to implement this using PagerTabIndicator.
Previously I was using com.astuetz.PagerSlidingTabStrip but since Its giving problem in Android studio 3.0 so I switched to com.hold1:pagertabindicator:1.0.2.
In PagerSlidingTabStrip there is listener called setOnPageChangeListener which having 3 methods by using them I am able to change tab text dynamically on page change. but now i need to implement same by using com.hold1:pagertabindicator:1.0.2.

Without me having to dig through two codebases, is there a quick and dirty comparison between the properties between PagerSlidingTabStrip and PagerTabIndicator?

I'm trying to sort out pstsTabBackgroundResIds for example, and I can't quite get my tab collection to go across the entire bottom of the view.

Basically, I'm seeing if I can switch from this layout fragment:

<com.astuetz.PagerSlidingTabStrip
        android:id="@+id/bottombar"
        android:layout_width="match_parent"
        android:layout_height="60dp"
        app:pstsDividerPadding="0dp"
        app:pstsIndicatorHeight="60dp"
        app:pstsIndicatorColor="@color/text_grey_500"
        app:pstsShouldExpand="true"
        app:pstsTabBackgroundResIds="@array/setting_tab_backgrounds"
        app:pstsTextAllCaps="false" />

How can i change font type or font family on tab text?

For some reason I'm unable to sync my Gradle with this implementation. is there anything special I need to know or understand when importing this into my android studio project? I have maven central and many other libraries, but for some reason yours 'fails to resolve'.

implementation 'com.hold1:pagertabindicator:1.0.7'

I need to change the only selected tab text color with remaining tab text should be same color

The tab text is cutting not displaying properly. Similar feature available on pagerslidingtabstrip (should_expand) which is working as expected. Please fix it. This is library is very useful for me. Other than pagerslidingtabstrip library isn't working after upgrading sdk.
Alternatively can you add text typeface function?

When i tried to run application Its giving me following error; but When I run application in debug mode its runs perfectly.

Following is way i implement PagerTabsIndicator;
In xml;

<com.hold1.pagertabsindicator.PagerTabsIndicator
        android:id="@+id/transactionTabs"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:layout_alignParentBottom="true"
        android:background="#FBE9E9EC"
        app:tab_indicator="bottom_bar"
        app:tab_indicator_bg_color="#FBE9E9EC"
        app:tab_lock_expanded="true"
        app:tab_divider_color="@color/colorPrimary"
        app:tab_indicator_color="@color/drawerBgColor"
        app:tab_indicator_height="80dp"
        />

In Activity;

tabPagerAdapter = new TransactionTabPagerAdapter(getSupportFragmentManager(),userTransactionResDTO,this);
mPager.setAdapter(tabPagerAdapter);
mTabStrip.setViewPager(mPager);

To change Tab text color dynamically I used;

if (position==0) {
mTabStrip.setTextColor(getResources().getColor(R.color.colorPrimary));
 } else {
mTabStrip.setTextColor(Color.BLACK);
}

In gradle;
compile 'com.hold1:pagertabindicator:1.0.5'

Hello, thanks for this lib, it is really nice, i found an issue, please have a look

to reproduce

1. create 2 tabs as usual
2. clear all the fragments list in the adapter
3. call notifyDataSetChanged()
4. add back the tabs in step 1
5. call notifyDataSetChanged() will throw an exception inside PagerTabsIndicator at below

if(this.targetPosition == -1) { this.scrollToChild(position, (int)(positionOffset * (float)this.tabsContainer.getChildAt(position).getWidth())); }

BTW, i found that the fragement will be resued unless I use FragmentStatePagerAdapter to be the base class of my adaption and with below also

public int getItemPosition(Object object) { return POSITION_NONE; }
