How to exec something when changing tabs ? Like a method or something is there any easy way ? I have searched for it but I have found something called TabHost can anyone explain me that too ?
Here is my tab code :
ublic class Testes extends AppCompatActivity {
private SectionsPagerAdapter mSectionsPagerAdapter;
private ViewPager mViewPager;
private DatePickerDialog.OnDateSetListener hourSetListener;
private DatePickerDialog.OnDateSetListener dateSetListener;
private Button date_button;
private Button hora_picker;
private TextView date_text;
private TextView hora_text;
private Caldroid_fragment cf;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_testes);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
// Create the adapter that will return a fragment for each of the three
// primary sections of the activity.
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
// Set up the ViewPager with the sections adapter.
mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
cf = new Caldroid_fragment();
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(mViewPager);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_testes, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()){
case go_to_fazer_media:{
if (item.isChecked())
item.setChecked(false);
else{
Intent i = new Intent(Testes.this,Formas.class);
startActivity(i);
return true;
}
}
case definicoes:{
if (item.isChecked())
item.setChecked(false);
else{
return true;
}
}
}
return super.onOptionsItemSelected(item);
}
public class SectionsPagerAdapter extends FragmentPagerAdapter {
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
switch(position){
case 0:
Tab1tests tab1 = new Tab1tests();
return tab1;
case 1:
Tab2calendar tab2 = new Tab2calendar();
return tab2;
default:
return null;
}
}
#Override
public int getCount() {
// Show 3 total pages.
return 2;
}
#Override
public CharSequence getPageTitle(int position) {
switch (position) {
case 0:
return "Adicionar Testes";
case 1:
return "Mapa de Testes";
}
return null;
}
}
EDIT:

If you are using TabLayout, use OnTabSelectedListener.
tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener(){
#Override
public void onTabSelected(TabLayout.Tab tab){
int position = tab.getPosition();
// Execute here based on position
switch(position){
case 0 :
break;
case 2 :
addToCalendar();
break;
}
});
Tab position starts at 0 and not 1.

Hello in my project I am to play a song when I click on a button and this button is is a fragment layout but I don't now if I need to put the code in the fragment or in the MainActivity. So here I put it in the fragment and the "protected" of the protected void is underline in red same for the "(this, resId)". Can someone help thanks a lot.
here is my fragment.java

I am using a tablayout to build my application but the tab indicator is not working when I slide within the tabs. Can anyone help me?I have tried adding the addOnTabSelectedListener but that did not work either.

if(mapFragment != null){
mapFragment.onRequestPermissionsResult(requestCode,permissions,grantResults);
}
}
else{
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
}
remove this:
tabLayout.addOnTabSelectedListener(new TabLayout.ViewPagerOnTabSelectedListener(viewPager));
And add:
tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
#Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager.setCurrentItem(tab.getPosition());
}
#Override
public void onTabUnselected(TabLayout.Tab tab) {
}
#Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
Also u should call tabLayout.setupWithViewPager(viewPager); after u set up the viewpager
viewPager = (ViewPager)findViewById(R.id.view_pager);
pagerAdapter = new PagerAdapter(getSupportFragmentManager(), MainActivity.this);
viewPager.setAdapter(pagerAdapter);
tabLayout.setupWithViewPager(viewPager);
My application was first created with the Tabbed Activity template given by Android studio. I have 5 tabs within that activity. Each of these tabs has a button that I can get to go to a new activity that I have created. I cannot, however get a button on the new activity to go back to the tab I first clicked the button on.

The button that I would like to add functionality to is on the activity_create_event.xml and I need it to take the user back to the Main Activity in the 4th tab.
Thanks for the help!!!
I have a tablayout, viewpager with 4 fragments.
I added bottombar in my MainActivity so it was showing all fragments.
I just want bottombar only in first fragment.
How to hide bottombar for other 3 fragments?
This is MainActivity:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//setHasOptionsMenu(true);
bottombar = BottomBar.attach(MainActivity.this,savedInstanceState);
bottombar.setItemsFromMenu(R.menu.bottom_bar_menu, new OnMenuTabSelectedListener() {
#Override
public void onMenuItemSelected(int itemId) {
switch (itemId) {
case R.id.about_us:
About_Us about_us = new About_Us();
Intent intent = new Intent(MainActivity.this,About_Us.class);
startActivity(intent);
break;
case R.id.contact_us:
SquareFragment squareFragment = new SquareFragment();
getSupportFragmentManager().beginTransaction().replace(R.id.frame,squareFragment).commit();
//squareFragment.updateColor(Color.parseColor(colors[1]));
break;
//Toast.makeText(MainActivity.this,"selected contact_us",Toast.LENGTH_SHORT).show();
case R.id.donate_us:
donate_us_Fragment donate_us_fragment = new donate_us_Fragment();
getSupportFragmentManager().beginTransaction().replace(R.id.frame,donate_us_fragment).commit();
//Toast.makeText(MainActivity.this,"selected donate_us",Toast.LENGTH_SHORT).show();
break;
}
}
});
bottombar.setActiveTabColor("#C2185B");
//Initializing the tablayout
tabLayout = (TabLayout) findViewById(R.id.tabLayout);
//Adding the tabs using addTab() method
tabLayout.addTab(tabLayout.newTab().setText("Home").setIcon(R.drawable.home_selector));
tabLayout.addTab(tabLayout.newTab().setText("News").setIcon(R.drawable.news_selector));
tabLayout.addTab(tabLayout.newTab().setText("Videos").setIcon(R.drawable.video_selector));
tabLayout.addTab(tabLayout.newTab().setText("PodCasts").setIcon(R.drawable.podcast_selector));
tabLayout.addTab(tabLayout.newTab().setText("More").setIcon(R.drawable.more_selector));
tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
//tabLayout.setupWithViewPager(viewPager);
//Initializing viewPager
viewPager = (ViewPager) findViewById(R.id.pager);
//Creating our pager adapter
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager(), tabLayout.getTabCount());
//Adding adapter to pager
viewPager.setAdapter(adapter);
viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.setOnTabSelectedListener(new TabLayout.ViewPagerOnTabSelectedListener(viewPager) {
#Override
public void onTabSelected(TabLayout.Tab tab) {
super.onTabSelected(tab);
}
}
This is ViewPagerAdapter:
public class ViewPagerAdapter extends FragmentStatePagerAdapter {
//integer to count number of tabs
int tabCount;
BottomBar bottombar;
//Constructor to the class
public ViewPagerAdapter(FragmentManager fm, int tabCount) {
super(fm);
//Initializing tab count
this.tabCount = tabCount;
}
//Overriding method getItem
#Override
public Fragment getItem(int position) {
//Returning the current tabs
switch (position) {
case 0:
return new Home_Fragment();
case 1:
News_Fragment news_fragment = new News_Fragment();
bottombar.hide();
return news_fragment;
case 2:
Video_Fragment video_fragment = new Video_Fragment();
return video_fragment;
case 3:
return new PodCasts_Fragment();
case 4:
return new More_Fragment();
}
return null;
}
//Overriden method getCount to get the number of tabs
#Override
public int getCount() {
return tabCount;
}
See this image below:
try this:
public void onTabSelected(TabLayout.Tab tab) {
if(tab.getPosition == 0 )
bottomBar.hide();
super.onTabSelected(tab);
}
And remove the
bottomBar.hide();
from the getItem() in the fragment.
this is correct code
viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.setOnTabSelectedListener(new TabLayout.ViewPagerOnTabSelectedListener(viewPager) {
#Override
public void onTabSelected(TabLayout.Tab tab) {
if(tab.getPosition() == 0){
bottombar.show();
}else
if(tab.getPosition() == 1){
bottombar.hide();
}else
if(tab.getPosition() == 2){
bottombar.hide();
}else
if(tab.getPosition() == 3){
bottombar.hide();
}
super.onTabSelected(tab);
}
#Override
public void onTabUnselected(TabLayout.Tab tab) {
super.onTabUnselected(tab);
//tab.getIcon().setAlpha(127);
}
});
}
}
I am developing an app which have a single activity and several fragments.
The first fragment contains a viewpager which have 3-4 fragments extra. I can switch from one fragment to another easily and the viewpager works fine, but when i am going back from one fragment to the first(not in viewpager), the viewpager is not loading all fragments. Below is the code:
