You can have a FragmentPagerAdapter to manager fragments and set this adapter into viewPager to slide fragments when you click on tabs or swipe to change tabs.
FragmentPagerAdapter:
public class TabLayoutViewPagerAdapter extends FragmentPagerAdapter {
private final int PAGE_COUNT = 3;
private final String[] mTabsTitle = {"Fragment A", "Fragment B, "Fragment C"};
private Context context;
private int[] mTabsIcons = {
R.drawable.a,
R.drawable.b,
R.drawable.c};
public TabLayoutViewPagerAdapter(FragmentManager fm, Context context) {
super(fm);
this.context = context;
}
public View getTabView(int position) {
View view = LayoutInflater.from(context).inflate(R.layout.custom_tab, null);
TextView title = (TextView) view.findViewById(R.id.title);
title.setText(mTabsTitle[position]);
title.setSingleLine(true);
ImageView icon = (ImageView) view.findViewById(R.id.icon);
icon.setImageResource(mTabsIcons[position]);
return view;
}
#Override
public Fragment getItem(int pos) {
switch (pos) {
case 0:
return new FragmentA();
case 1:
return new FragmentB();
case 2:
return new FragmentC();
}
return null;
}
#Override
public int getCount() {
return PAGE_COUNT;
}
#Override
public CharSequence getPageTitle(int position) {
return mTabsTitle[position];
}}
How you use it:
ViewPager viewPager = (ViewPager) findViewById(R.id.viewPager);
TabLayoutViewPagerAdapter pagerAdapter = new TabLayoutViewPagerAdapter(getSupportFragmentManager(), this);
if (viewPager != null) {
viewPager.setAdapter(pagerAdapter);
}
You need a TabLayout:
mTabLayout = (TabLayout) findViewById(R.id.tabLayout);
if (mTabLayout != null) {
mTabLayout.setupWithViewPager(viewPager);
//populate your tabs
for (int i = 0; i < mTabLayout.getTabCount(); i++) {
TabLayout.Tab tab = mTabLayout.getTabAt(i);
if (tab != null)
tab.setCustomView(pagerAdapter.getTabView(i));
}
TabLayout.Tab tab = mTabLayout.getTabAt(0);
if (tab != null && tab.getCustomView() != null) {
tab.getCustomView().setSelected(true);
}
}
How to select a page:
private void selectPage(int pageIndex) {
mTabLayout.setScrollPosition(pageIndex, 0f, true);
viewPager.setCurrentItem(pageIndex);
}
Do not forget to create your customTab.xml.
Best regards.

In Fragment A's onClick() method, try this :
TabActivity tabs = (TabActivity) getParent();
tabs.getTabHost().setCurrentTab(2);

creating a fragment hit counter

I have a really basic app that has three fragments - fragments a,b and c, each of these fragments contains a piece of text that reads "I have been visited " + tallyVariable + " this many times".
I'm not entirely sure this is the correct way of doing it as I am new to app development and fairly new to the java language, but have attempted to give it a go.
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.app.FragmentStatePagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
public class MainActivity extends FragmentActivity {
//tally variables
public int numSwipes = 0;
public int numSwipes2 = 0;
public int numSwipes3 = 0;
ViewPager viewPager = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
viewPager = (ViewPager)findViewById(R.id.pager);
FragmentManager fragmentManager = getSupportFragmentManager();
viewPager.setAdapter(new MyAdapter(fragmentManager));
}
}
class MyAdapter extends FragmentStatePagerAdapter{
// reference to MainActivity and variables
MainActivity mainActivity = new MainActivity();
int fragNumSwipes = mainActivity.numSwipes;
int fragNumSwipes2 = mainActivity.numSwipes2;
int fragNumSwipes3 = mainActivity.numSwipes3;
public MyAdapter(FragmentManager fm) {
super(fm);
}
//#Override
public Fragment getItem(int i) {
Fragment fragment = null;
if(i==0)
{
fragment = new FragmentA();
fragNumSwipes++;
}
if(i==1)
{
fragment = new FragmentB();
fragNumSwipes2++;
}
if(i==2)
{
fragment = new FragmentC();
fragNumSwipes3++;
}
return fragment;
}
#Override
public int getCount() {
return 3;
}
public CharSequence getPageTitle(int position){
if(position==0)
{
return "tab 1";
}
if(position==1)
{
return "tab 2";
}
if(position==2)
{
return "tab 3";
}
return null;
}
}
below is the code for one of the fragments (code for the rest of the fragments is identical).
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
public class FragmentA extends Fragment {
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_a,container,false);
}
// MyAdapter adapterVariables = new MyAdapter();
}
I have commented out the above variable declaration "adapterVariables", but when it is active, it will not let me create a reference to the MyAdapter class where the tally variables now exist? what am I missing, I think it expects something between the parenthesis?

MainActivity mainActivity = new MainActivity(); this does not create a reference to your MainActivity! The same goes for your fragments code. You are creating new instances of your classes. You can pass references in your constructors. But for your idea, you won't need this. Below, you can find a corrected version, if you have questions about it, feel free to ask!
public class MainActivity extends FragmentActivity {
//tally variables
private int numSwipes = 0;
private int numSwipes2 = 0;
private int numSwipes3 = 0;
ViewPager viewPager = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
viewPager = (ViewPager)findViewById(R.id.pager);
FragmentManager fragmentManager = getSupportFragmentManager();
viewPager.setAdapter(new MyAdapter(fragmentManager));
//instead of increasing the number in the adapter, add a listener, since this is a better place to do it.
viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
#Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
}
#Override
public void onPageSelected(int position) {
switch(position){
case 0:
numSwipes++;
break;
case 1:
numSwipes2++;
break;
case 2:
numSwipes3++;
break;
}
}
#Override
public void onPageScrollStateChanged(int state) {
}
});
}
}
class MyAdapter extends FragmentStatePagerAdapter {
public MyAdapter(FragmentManager fm) {
super(fm);
}
#Override
public int getCount() {
return 3;
}
public CharSequence getPageTitle(int position){
if(position==0)
{
return "tab 1";
}
if(position==1)
{
return "tab 2";
}
if(position==2)
{
return "tab 3";
}
return null;
}
}

How to add Tabhost in Navigation Drawer

Camera opening on two different tabs

I am fairly new to developing Android applications. I am trying to create an application that allows you to save a picture in the "Pictures" folder named Property_Picture.jpg using the last (camera) tab. However, both the last two tabs are opening the camera, and the picture is also not being saved once you take a picture. Any help would be greatly appreciated. Thank you!

Where to place MediaPlayer in a fragment?

I would like to make my sound file play automatically when I arrive at a new fragment (by swiping). Right now, the sound doesn't play. Is there perhaps a fundamental difference between
public void OnAttach(Activity Fragment1){
and
public void OnAttach(Fragment Fragment1){
Thanks for any help. Code:
package com.example.test21;
import java.util.Locale;
import android.app.ActionBar;
import android.app.FragmentTransaction;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;

mViewPager.setAdapter(mSectionsPagerAdapter);
mViewPager
.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {

}
});
for (int i = 0; i < mSectionsPagerAdapter.getCount(); i++) {

MediaPlayer need a context to instantiate. You are passing in a Fragment. You can create it at onAttach
http://developer.android.com/reference/android/app/Fragment.html#onAttach(android.app.Activity)
http://developer.android.com/guide/components/fragments.html#EventCallbacks

You put it in method onCreateView() if you want play sound when you start new fragment.

Media Player creation needs context but fragment don't have the context
For creating Media Player in a fragment you need to use getActivity() for getting the context
Example:
// creating media player in a fragment
happyBirthdaySong = MediaPlayer.create(getActivity(), R.raw.happy_birthday_female);
happyBirthdaySong.setLooping(true);
happyBirthdaySong.start();
