The PagerTitleStrip is overflowing. I am not able to see all the title at a time. Not able to make out what i am missing here. I have attached the screenshots.
Also how do i add material UI theme to these tabs. which library is required and how to i apply the theme for the tab or for the entire application
My adapter code
public class MyAdapter extends FragmentPagerAdapter
{
int totalFragments = 3;
public MyAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
return MyFragment.newInstance(position);
}
#Override
public int getCount() {
return totalFragments;
}
#Override
public CharSequence getPageTitle(int position) {
switch (position) {
case 0:
return "Tab One";
case 1:
return "Tab Two";
case 2:
return "Tab Three";
}
return null;
}
}

First, where you have used fill_parent, replace those with match_parent, since filling is deprecated.
Second, the common settings for ViewPager size are
android:layout_width="match_parent"
android:layout_height="0px"
and possibly
android:layout_weight="1"
After these, for your PagerTitleStrip, try
android:layout_width="wrap_content"
Third, The material way of designing tabbed vies is with TabLayout, which Google has some tutorials and examples for.

EDIT: Oh sry i'm using another lib:

When you want to display only selected tab and other will hide then set your PagerTabStrip as bellow.
<android.support.v4.view.PagerTabStrip
android:id="#+id/pager_header"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="top"
android:paddingBottom="4dp"
android:paddingTop="4dp"
app:tabMode="scrollable"
app:tabTextColor="#000000"
app:tabSelectedTextColor="#ff0000"
app:tabIndicatorColor="#ff0000"/>
app:tabTextColor="" is your normal tab text color.
app:tabSelectedTextColor="" is color of your selected tab.
app:tabIndicatorColor="" is your selected tab indicatore color.
So use as per your requirement. For detail that how to use tab layout then check this tutorial.
I have a viewPager that has 6 pages and in each page there is a PullToRefreshGridView.
I found that I have to click twice to triggered the click event or scroll the GridView.
The first click didn't triggered the click event.
These 6 pages have the same situation.
Please can someone help me to debug and tell me what am I doing wrong here.
This is my code:
viewPager = (ViewPager)findViewById(R.id.viewPager);
adapterViewPager = new MyPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(adapterViewPager);
viewPager.setCurrentItem(0);
viewPager.addOnPageChangeListener(this);
viewPager.setOffscreenPageLimit(0);
and MyPagerAdapter is:
public static class MyPagerAdapter extends FragmentStatePagerAdapter {
private static int NUM_ITEMS = 6;
public MyPagerAdapter(FragmentManager fragmentManager) {
super(fragmentManager);
}
#Override
public void destroyItem(View collection, int position, Object o) {
Log.d("DESTROY", "destroying view at position " + position);
View view = (View) o;
((ViewPager) collection).removeView(view);
view = null;
}
// Returns total number of pages
#Override
public int getCount() {
return NUM_ITEMS;
}
// Returns the fragment to display for that page
#Override
public Fragment getItem(int position) {
switch (position)
{
case 0:
return TypeZero.newInstance("", "Page # 1");
case 1:
return TypeOne.newInstance("", "Page # 2");
case 2:
return TypeTwo.newInstance("", "Page # 3");
case 3:
return TypeThree.newInstance("", "Page # 4");
case 4:
return TypeFour.newInstance("", "Page # 5");
case 5:
return TypeFive.newInstance("", "Page # 6");
default:
return null;
}
}
// Returns the page title for the top indicator
#Override
public CharSequence getPageTitle(int position) {
switch(position)
{
case 0:
return "Zero";
case 1:
return "One";
case 2:

viewPager.invalidate();
viewPager.requestLayout();
I found that I add
main_layout.setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
at every activity of gridview inside the viewPager.
This one cause the focus false.
I referred this Pager Sliding Tab Strip.I am getting the output as it is.
But my only problem is I didn't know how to add the button for categories tab,Textview for Home tab,Edittext for Top Paid tab.
There I seen only two layout :

public CharSequence getPageTitle(int position) {
return TITLES[position];
}
#Override
public int getCount() {
return TITLES.length;
}
return SuperAwesomeCardFragment.newInstance(position);
}
}
If I add a button in activity_main.xml. It just add the button not only in Category tab.But, it added the button in all tabs.
I need to add the button in category tab.Then I have to add the edit text in Home tab.is it possible to do this in Pager Sliding Tab Strip.
Edit: There was no xml layout separately for category tab and home tab.That's why I am getting confused with this.
you should add the button on Category Tab fragment layout, not activity_main layout
The user #Calvinfly suggested me,so I can found out the answer.To be more Clear:
In my MainActivity.java inside MyPagerAdapter I set the position like this
#Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return new Category();
case 1:
return new Home();
case 2:
return new TopPaid();
}
return SuperAwesomeCardFragment.newInstance(position);
}
I am in the process of creating my first app and learning java for the first time as well, and am stuck on creating tabs on the toolbar..
I took a look at this post. However I was still confused on how to properly implement them. Should I be downloading the SlidingTabsColors file, and then adding it as a dependency in gradle.build?
In this section: fragment_sample.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:layout_width="match_parent"
android:layout_height="wrap_content" >

android:layout_height="wrap_content" />

android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="0px"
android:layout_weight="1"
android:background="#android:color/white" />
</LinearLayout>
I can not add com.example.android.common.view.SlidingTabLayout to the layout.
Thank you
Try this
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

<com.example.android.common.view.SlidingTabLayout
android:id="#+id/sliding_tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="0px"
android:layout_weight="1"
android:background="#android:color/white" />
</LinearLayout>
For a better implementation try:
add this to your gradle dependences
compile 'com.astuetz:pagerslidingtabstrip:1.0.1'
Then instead of the SlidingTabLayout use
<com.astuetz.PagerSlidingTabStrip
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="48dip" />
In your activity where you want to call the ViewPager You have to
// Initialize the ViewPager and set an adapter
ViewPager pager = (ViewPager) findViewById(R.id.viewpager);
pager.setAdapter(new YourCustomAdapter(getSupportFragmentManager()));
// Bind the tabs to the ViewPager
PagerSlidingTabStrip tabs = (PagerSlidingTabStrip) findViewById(R.id.tabs);
tabs.setViewPager(pager);
You might want to implement your adapter like this:
public class YourCustomAdapter extends FragmentStatePagerAdapter {
private String[] titles = { "Item 1", "Item 2", "Item 3" };
public YourCustomAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
switch(position){
case 0:{
return new YourFragment();
}
case 1:{
return new YourFragment();
}
case 2:{
return new YourFragment();
}
}
return null;
}
#Override
public int getCount() {
return titles.length;
}
#Override
public CharSequence getPageTitle(int position) {
return titles[position];
}
}
Hope it helps!!!
Hi i have to implement ViewPager in my app. here i have to load ImageAdapter that extends PagerAdapter and i successfully see all the images into viewpager.
Now, i want to display viewpager title as my image counter.
Layout.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/gallery_detail_layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#color/black" >
<android.support.v4.view.ViewPager
android:id="#+id/view_pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/rel_ig" >
</android.support.v4.view.ViewPager>
</RelativeLayout>
Please some one give me information how i want to do that!
First need to add android.support.v4.view.PagerTabStrip into your Layout.xml file like:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/gallery_detail_layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#color/black" >
<android.support.v4.view.ViewPager
android:id="#+id/view_pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/rel_ig" >
<android.support.v4.view.PagerTabStrip
android:id="#+id/pts_main"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</android.support.v4.view.ViewPager>
</RelativeLayout>
Now, override CharSequence getPageTitle(int position) method int you Adapter like:
public class ImageAdapter extends PagerAdapter {
............
#Override
public CharSequence getPageTitle(int position) {
return (position + 1);
}
...........
}
And implement into your PagerTabStrip like: you can customized PagerTabStrip options
PagerTabStrip strip = (PagerTabStrip)view.findViewById(R.id.pts_main);
strip.setDrawFullUnderline(false);
strip.setTabIndicatorColor(Color.DKGRAY);
strip.setBackgroundColor(Color.GRAY);
strip.setNonPrimaryAlpha(0.5f);
strip.setTextSpacing(25);
strip.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 16);
Try This :-
add a PagerTitleStrip in activity_main.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<android.support.v4.view.ViewPager
android:id="#+android:id/viewpager"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<android.support.v4.view.PagerTitleStrip
android:id="#+id/pgrStrp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="top" />
</android.support.v4.view.ViewPager>
</LinearLayout>
Then in PageAdapter.java add the following method:
#Override
public CharSequence getPageTitle(int position) {
return "Title Here";
}
