Android using fragments

Android using fragments - android

I want to start a fragment with using onclick function.How can I do this ? I am using this code:
package info.androidhive.tabsswipe;
import info.androidhive.tabsswipe.adapter.TabsPagerAdapter;
import info.androidhive.tabsswipe.R;
import android.app.ActionBar;
import android.app.ActionBar.Tab;
import android.app.FragmentTransaction;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.view.ViewPager;
import android.view.Menu;
public class MainActivity extends FragmentActivity implements
ActionBar.TabListener {
private ViewPager viewPager;
private TabsPagerAdapter mAdapter;
private ActionBar actionBar;
// Tab titles
private String[] tabs = { "Top Rated", "Games", "Movies" };
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Initilization
viewPager = (ViewPager) findViewById(R.id.pager);
actionBar = getActionBar();
mAdapter = new TabsPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(mAdapter);
actionBar.setHomeButtonEnabled(false);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
// Adding Tabs
for (String tab_name : tabs) {
actionBar.addTab(actionBar.newTab().setText(tab_name)
.setTabListener(this));
}
/**
* on swiping the viewpager make respective tab selected
* */
viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
#Override
public void onPageSelected(int position) {
// on changing the page
// make respected tab selected
actionBar.setSelectedNavigationItem(position);
}
#Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
#Override
public void onPageScrollStateChanged(int arg0) {
}
});
}
#Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
}
#Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
// on tab selected
// show respected fragment view
viewPager.setCurrentItem(tab.getPosition());
}
#Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
}
}
I want create a function in mainactivity and when this function is run I want to change fragment.
Ps:I don't want to add this fragment to tabs.
Other codes(layout,tabs adapter etc):http://www.androidhive.info/2013/10/android-tab-layout-with-swipeable-views-1/#disqus_thread

Assuming that you already know how to create the Fragment class, all you need to do is:
#Override
public void onClick(View view) {
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.add(R.id.container, new YourFragment());
fragmentTransaction.commit();
}
R.id.container is the layout where you are adding the Fragment. It should be in you main.xml
EDIT
You need a container for your Fragment so in your xml you need something like this:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</FrameLayout>
Now when you add the Fragment it will be inflated inside of that container.

How Can i Implementing Swipe View in ActionTab and Fragments within Multiple Fragments?

I am working on Actionbar.TabListener and Fragments
Tab.
Fragments contains multiple Fragments that are generated via clickable buttons on each tabbed Fragments.
My MainActivity and other files are shown below:
My main activity is as follows:
import android.app.ActionBar;
import android.app.Fragment;
import android.os.Bundle;
import android.app.Activity;
public class MainActivity extends Activity {
// Declare Tab Variable
ActionBar.Tab Tab1, Tab2, Tab3;
Fragment fragmentTab1 = new FragmentTab1();
Fragment fragmentTab2 = new Mcx();
Fragment fragmentTab3 = new FragmentTab3();
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ActionBar actionBar = getActionBar();
// Hide Actionbar Icon
actionBar.setDisplayShowHomeEnabled(false);
// Hide Actionbar Title
actionBar.setDisplayShowTitleEnabled(false);
// Create Actionbar Tabs
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
// Set Tab Icon and Titles
Tab1 = actionBar.newTab().setText("A");
Tab2 = actionBar.newTab().setText("B");
Tab3 = actionBar.newTab().setText("C");
// Set Tab Listeners
Tab1.setTabListener(new TabListener(fragmentTab1));
Tab2.setTabListener(new TabListener(fragmentTab2));
Tab3.setTabListener(new TabListener(fragmentTab3));
// Add tabs to actionbar
actionBar.addTab(Tab1);
actionBar.addTab(Tab2);
actionBar.addTab(Tab3);
}
}
And TabListener file that extends ActionBar.Tablistener:
import android.app.ActionBar.Tab;
import android.app.Fragment;
import android.app.FragmentTransaction;
import android.app.ActionBar;
public class TabListener implements ActionBar.TabListener {
Fragment fragment;
public TabListener(Fragment fragment) {
// TODO Auto-generated constructor stub
this.fragment = fragment;
}
#Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
// TODO Auto-generated method stub
ft.replace(R.id. fragment_container, fragment);
}
#Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
// TODO Auto-generated method stub
ft.remove(fragment);
}
#Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
// TODO Auto-generated method stub
}
}
activity_main.xml is configured as the following:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
Question:
Given what I have implemented above, how could I go about implementing both ActionTab and Fragment View as a swipe view?

After some research on the google i found that we can achieve swipe view in fragments with Tab with the use of ViewPager
Go to Android Studio and select TabActivity (Swipe with ViewPager template)
first we have to extend fragmentAcitvity with MainActivity, and that should be implemented with ActionBar.TabListener
The Code is as follows..
import android.app.ActionBar;
import android.app.ActionBar.Tab;
import android.app.FragmentTransaction;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.view.ViewPager;
#SuppressWarnings("ALL")
public class MainActivity extends FragmentActivity implements ActionBar.TabListener{
ActionBar actionbar;
public static ViewPager viewpager;
FragmentPageAdapter ft;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
viewpager = (ViewPager) findViewById(R.id.pager);
ft = new FragmentPageAdapter(getSupportFragmentManager());
actionbar = getActionBar();
viewpager.setAdapter(ft);
actionbar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
actionbar.addTab(actionbar.newTab().setText("TAB1").setTabListener(this));
actionbar.addTab(actionbar.newTab().setText("TAB2").setTabListener(this));
actionbar.addTab(actionbar.newTab().setText("TAB3").setTabListener(this));
actionbar.addTab(actionbar.newTab().setText("TAB").setTabListener(this));
viewpager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
#Override
public void onPageSelected(int arg0) {
actionbar.setSelectedNavigationItem(arg0);
}
#Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
// TODO Auto-generated method stub
}
#Override
public void onPageScrollStateChanged(int arg0) {
// TODO Auto-generated method stub
}
});
}
#Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
// TODO Auto-generated method stub
}
#Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
viewpager.setCurrentItem(tab.getPosition());
}
#Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
// TODO Auto-generated method stub
}
}
XML for MainActivity .... activity_mail.xml will be...
<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:id="#+id/pager"
android:layout_width="match_parent" android:layout_height="match_parent"
tools:context=".MainActivity" />
FragmentpageAdapter
public class FragmentPageAdapter extends FragmentPagerAdapter {
public FragmentPageAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int arg0) {
switch (arg0){
case 0: return new Tab1Fragment();
case 1: return new Tab2Fragment();
case 2: return new Tab3Fragment();
case 3: return new Tab4Fragment();
default:break;
}
return null;
}
#Override
public int getCount() {
return 4;
}
#Override
public CharSequence getPageTitle(int position) {
return getPageTitle(4);
}
}
If you take By default Template in Android Studio as mentioned above there will be an fragment_main file also ...
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent" android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:paddingBottom="#dimen/activity_vertical_margin"
tools:context=".MainActivity$PlaceholderFragment">
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/toolbar"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
android:popupTheme="#style/ThemeOverlay.AppCompat.Light">
</android.support.v7.widget.Toolbar>
</RelativeLayout>
After that implement all Fragments with related Tabs that you declared and added in FragmentPagerAdapter and MainActivity.
You have to set activity theme in Androidmenifest.xml
"#android:style/Theme.Holo.Light"
and also in style.xml
<style name="AppTheme" parent="Theme.AppCompat">

Can't resolve method getActionBar()(Android Studio)

I am new to Android Studio..I am getting following error in Android Studio.."Can't resolve method getActionBar()' in the statement actionBar = getActionBar();..Project was running fine in Eclipse..plzz Help me with this error

// on tab selected
// show respected fragment view
viewPager.setCurrentItem(tab.getPosition());
}
#Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
}
}

if your target API is below hony must do change these lines:
Create your activity by extending ActionBarActivity.
ActionBar actionBar = getSupportActionBar();
Use (or extend) one of the Theme.AppCompat themes for your activity
I think you confuse API versions, for example you must call getSupportFragmentManager() in low API and getFragmentManager() on above API 11 and you do not need extend FragmentActivity in API 11 and above because it actually have all functions

Changing the starting tab of multiple swipe views with tabs

So I am "playing" around with some code i got from a tutorial on Tab layout with swipeable views..
My Problem is that I cannot figure out how to change the default tab it opens, when the app is launched.. Right now it starts in the 1st tab(Top Rated) but I want to have it start the second tab called Games?
I've browsed around and looked for solutions but doesn't seem to find one that fits my code..
Here is my main acitivity:
package info.androidhive.tabsswipe;
import info.androidhive.tabsswipe.adapter.TabsPagerAdapter;
import android.app.ActionBar;
import android.app.ActionBar.Tab;
import android.app.FragmentTransaction;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.view.ViewPager;
public class MainActivity extends FragmentActivity implements
ActionBar.TabListener {
private ViewPager viewPager;
private TabsPagerAdapter mAdapter;
private ActionBar actionBar;
// Tab titles
private String[] tabs = { "Top Rated", "Games", "Movies" };
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Initilization
viewPager = (ViewPager) findViewById(R.id.pager);
actionBar = getActionBar();
mAdapter = new TabsPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(mAdapter);
actionBar.setHomeButtonEnabled(false);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
// Adding Tabs
for (String tab_name : tabs) {
actionBar.addTab(actionBar.newTab().setText(tab_name)
.setTabListener(this));
}
/**
* on swiping the viewpager make respective tab selected
* */
viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
#Override
public void onPageSelected(int position) {
// on changing the page
// make respected tab selected
actionBar.setSelectedNavigationItem(position);
}
#Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
#Override
public void onPageScrollStateChanged(int arg0) {
}
});
}
#Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
}
#Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
// on tab selected
// show respected fragment view
viewPager.setCurrentItem(tab.getPosition());
}
#Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
}
}

In your addTab call, add the one you want set first followed by the rest.
So change
// Adding Tabs
for (String tab_name : tabs) {
actionBar.addTab(actionBar.newTab().setText(tab_name)
.setTabListener(this));
}
to
actionBar.addTab(actionBar.newTab().setText(tabs[1])
.setTabListener(this), 1, true);
actionBar.addTab(actionBar.newTab().setText(tabs[0])
.setTabListener(this), 0, false);
actionBar.addTab(actionBar.newTab().setText(tabs[2])
.setTabListener(this), 2, false);
See Android ActionBar tabs set initially selected tab

Android: method does not override or implement a method from a supertype

I am trying to build a simple three (3) tabs app. I am supposed to be implementing three public methods of ActionBar.TabListener.
I believe that is exactly what I am doing in the below code. The compiler however believes that I do not. All three come with the error: "method does not override or implement a method from supertype"
I checked methods' signatures, do not even know where to look, now.
Please advise.
import android.app.ActionBar;
import android.app.ActionBar.Tab;
import android.support.v4.app.FragmentTransaction;
import android.os.Bundle;
import android.support.v4.view.ViewPager;
import android.support.v4.app.FragmentActivity;
public class InSync extends FragmentActivity implements ActionBar.TabListener {
private ViewPager viewPager;
private TabsPagerAdapter mAdapter;
private ActionBar actionBar;
// Tab titles
private String[] tabs = { "Backup", "Restore", "Settings"};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_in_sync);
// Initilization
viewPager = (ViewPager) findViewById(R.id.pager);
actionBar = getActionBar();
mAdapter = new TabsPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(mAdapter);
actionBar.setHomeButtonEnabled(false);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
// Adding Tabs
for (String tab_name : tabs) {
actionBar.addTab(actionBar.newTab().setText(tab_name)
.setTabListener(this));
}
/**
* on swiping the viewpager make respective tab selected
* */
viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
#Override
public void onPageSelected(int position) {
// on changing the page
// make respected tab selected
actionBar.setSelectedNavigationItem(position);
}
#Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
#Override
public void onPageScrollStateChanged(int arg0) {
}
});
}
#Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
// on tab selected
// show respected fragment view
viewPager.setCurrentItem(tab.getPosition());
}
#Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
}
#Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
}
}
Thank you.

I believe, you messed up with support libraries. Try
import android.app.FragmentTransaction;
instead of
import android.support.v4.app.FragmentTransaction;
Upd.
Or better use only support libraries:
import android.support.v4.app.FragmentTransaction;
import android.os.Bundle;
import android.support.v4.view.ViewPager;
import android.support.v4.app.FragmentActivity;
import android.support.v7.app.ActionBar;
import android.support.v7.app.ActionBar.Tab;

The methods you try to implement are
void onTabReselected(ActionBar.Tab tab, FragmentTransaction ft)
void onTabSelected(ActionBar.Tab tab, FragmentTransaction ft)
and
void onTabUnselected(ActionBar.Tab tab, FragmentTransaction ft)
I guess the Tab class you are using is not the "right" Tab class.
EDIT:
On this link you can see that there is a certain android.app.FragmentTransaction. However, you have imported android.support.v4.app.FragmentTransaction. Isn't it possible that this is the problem, as the links to FragmentTransaction from here point to the page of android.app.FragmentTransaction. I believe you should have this code:
import android.app.ActionBar;
import android.app.ActionBar.Tab;
import android.app.FragmentTransaction;
import android.os.Bundle;
import android.support.v4.view.ViewPager;
import android.support.v4.app.FragmentActivity;
public class InSync extends FragmentActivity implements ActionBar.TabListener {
private ViewPager viewPager;
private TabsPagerAdapter mAdapter;
private ActionBar actionBar;
// Tab titles
private String[] tabs = { "Backup", "Restore", "Settings"};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_in_sync);
// Initilization
viewPager = (ViewPager) findViewById(R.id.pager);
actionBar = getActionBar();
mAdapter = new TabsPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(mAdapter);
actionBar.setHomeButtonEnabled(false);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
// Adding Tabs
for (String tab_name : tabs) {
actionBar.addTab(actionBar.newTab().setText(tab_name)
.setTabListener(this));
}
/**
* on swiping the viewpager make respective tab selected
* */
viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
#Override
public void onPageSelected(int position) {
// on changing the page
// make respected tab selected
actionBar.setSelectedNavigationItem(position);
}
#Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
#Override
public void onPageScrollStateChanged(int arg0) {
}
});
}
#Override
public void onTabSelected(ActionBar.Tab tab, android.app.FragmentTransaction ft) {
// on tab selected
// show respected fragment view
viewPager.setCurrentItem(tab.getPosition());
}
#Override
public void onTabUnselected(ActionBar.Tab tab, android.app.FragmentTransaction ft) {
}
#Override
public void onTabReselected(ActionBar.Tab tab, android.app.FragmentTransaction ft) {
}
}
and if it works you can test even without namespaces.

Android ActionBar custom view and title change with tab nevigation.

I am trying to developing Tab Navigation app in Android. I have three tab. Every tab is swipable.
MainClass extends SherlockFragmentActivity from where tab are created. Every class is extends SherlockFragment.

Can anyone please help me.
