Android: Switching activities in swipeable tab layout

Android: Switching activities in swipeable tab layout - java

In my android app there is a swipeable tab layout. It has two tabs: New Complain and Previous Complains. When click the complain tab I need to start NewComplain.java. Here is my NewComplain class code segment:
NewComplain class
public class NewComplain extends SherlockFragmentActivity implements View.OnClickListener {
private int Year;
private int Month;
private int Day;
private static final int DATE_DIALOG_ID = 1;
private View viewLoad;
private TextView heading, date;
private Spinner spiComplain, spiProduct;
private EditText description, contInfo;
private Button btnDate;
private ArrayAdapter<String> complainAdapter, prodAdapter;
private ArrayList<String> lstComplain = new ArrayList<String>();
private ArrayList<String> lstProdNames = new ArrayList<String>();
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
viewLoad = LayoutInflater.from(NewComplain.this).inflate(
R.layout.new_complain, null);
setContentView(viewLoad);
}
}
This id my TabsPagerAdapter class.
package xont.virtusel.v4.controller.sale;
import android.content.Intent;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
public class TabsPagerAdapter extends FragmentPagerAdapter {
public TabsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int index) {
switch (index) {
case 0:
case 1:
}
return null;
}
#Override
public int getCount() {
// get item count - equal to number of tabs
return 2;
}
}
And this is my main activity class.
package xont.virtusel.v4.controller.sale;
import xont.virtusel.v4.controller.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;
public class CustomerComplainActivity extends FragmentActivity implements ActionBar.TabListener {
private ViewPager viewPager;
private TabsPagerAdapter mAdapter;
private ActionBar actionBar;
private String[] tabs = { "New Complain", "Previous Complains" };
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Initialization
viewPager = (ViewPager) findViewById(R.id.pager);
actionBar = getActionBar();
mAdapter = new TabsPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(mAdapter);
actionBar.setDisplayHomeAsUpEnabled(true);
//actionBar.setHomeButtonEnabled(true);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
//actionBar.setDisplayShowHomeEnabled(false);
//actionBar.setDisplayShowTitleEnabled(false);
// 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) {
}
}
How should I add switching activity statements into this TabsPagerAdapter class. I used intent. But it's not worked.
Can anyone plz be so kind enough to clarify this issue.
Thanx in advance

What exactly is your problem?
If you can't start new Fragment, try this:
in TabsPagerAdapter in public Fragment getItem() method
#Override
public Fragment getItem(int index) {
switch (index) {
case 0:
return new NewComplain();
case 1:
//return some other class
}
return null;
}
and create a constructor for NewComplain class

You are adding fragments, not activities. In your Tab listeners, you are given a FragmentTransaction which you should be using to update which of your fragments is showing with respect to the tab pressed.
Also, don't inflate in fragment on create, do that in on create view.

Update Tab fragment TextViews during runtime

I have been researching how to accomplish an activity with tabs and have gotten very close to completion. Unfortunately, I have hit a bit of a roadblock.
After following a great guide, I created an interactive activity with a tabLayout and a ViewPager to display the fragment.
Each tab displays the same layout, which is a column of TextViews on the left which keep their default value, and another column of TextViews that need to get their value from different locations.
As a test, I had each tab send different text values to their respective TextViews (example Tab #1 was assigned to use "Downstairs", #2 was assigned to use "Upstairs") - which is accomplished through the onTabSelected listener.
The issue I am running in to, is when the text is assigned to the TextViews. It never displays when the tab is selected. It sometimes displays on the next tab I open. It also sometimes displays Tab 1 assignment values in Tab 3 after I had already opened tab 2 before opening tab 3.
Every other TextView I have worked with updates right away when I use setText(). However, I am very new to using Tab Activities, so I very well could be messing something up.

I was attempting to design it in a way that uses SharedPreferences to store and read persistent data. There is a specific sharedPrefs files for each corresponding tab. You will notice that sharedPrefs have not been implemented, and is that way as I wanted to test with just basic setText.

*EDIT*
Changing this line:
ImageView myView = new ImageView(Logger.this.getActivity().getApplicationContext());
to this:
ImageView myView = new ImageView((Logger)getActivity().getApplicationContext());
solved the problem, but that was not what I was looking for. Thanks to Kapil Vij for correct Answer!

Do this
ImageView myView = new ImageView(getActivity());
getActivity() method is accessible in fragment class, and u r trying to access it using FragmentActivity class instance.

change to:
Logger.this.getApplicationContext()
Logger it-self is activity you call getActivity to get the reference of the activity inside a Fragment
EDIT
Saw that you are calling it inside a fragment change you code to:
ImageView myView = new ImageView(KayitFragment.this.getActivity().getApplicationContext());

Adding tabs below the action bar

In my android application I have implemented a tab layout with swipeable views. Here is my MainActivity class:
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 CustomerComplainActivity extends FragmentActivity implements ActionBar.TabListener {
private ViewPager viewPager;
private TabsPagerAdapter mAdapter;
private ActionBar actionBar;
private String[] tabs = { "New Complain", "Previous Complains" };
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Initialization
viewPager = (ViewPager) findViewById(R.id.pager);
actionBar = getActionBar();
mAdapter = new TabsPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(mAdapter);
//actionBar.setDisplayHomeAsUpEnabled(false);
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) {
}
}
And this is my TabPager Adapter class:
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
public class TabsPagerAdapter extends FragmentPagerAdapter {
public TabsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int index) {
switch (index) {
case 0:
// Top Rated fragment activity
return new NewComplain();
case 1:
return new PreviousComplains();
}
return null;
}
#Override
public int getCount() {
// get item count - equal to number of tabs
return 2;

This is my activity_main.xml file.
<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=".AdminMainActivity" >
<android.support.v4.view.PagerTitleStrip
android:id="#+id/pager_title_strip"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="top"
android:background="#800000"
android:paddingBottom="4dp"
android:paddingTop="5dp"
android:textColor="#fff"
android:textSize="18dp" />
This works, but the problem is the tabs are adding into the actiob bar as following.
But I want to add these tabs below the action bar. I would be much appreciated if anyone plz be so kind enough to explain how can I solve this problem.
Thanx in advance

I have same issue. I found the solution by replacing this line
actionBar.setHomeButtonEnabled(false);
with
actionBar.setDisplayShowHomeEnabled(true);
and your problem is solved.

Changing Fragments inside FrameLayout and Tabbed Navigation not Working

I am trying to have a tabbed navigation set up in the action bar. When you tap a tab, the frameLayout should change to one of 4 possible fragments in that activity.
However, it's stuck in the first Fragment and when i tap the tabs, nothing happens. Any ideas on what might be wrong? I suspect I am doing something wrong in terms of handling the listener for the tabs, but I can't figure it out (very frustrating). Any help? Thanks in advance.

Why not use a ViewPager that navigates with tabs? The Android Developer site has an excellent tutorial on Creating Swipe Views with Tabs.

Android: Switching activities in swipeable tab layout - java

You are adding fragments, not activities. In your Tab listeners, you are given a FragmentTransaction which you should be using to update which of your fragments is showing with respect to the tab pressed. Also, don't inflate in fragment on create, do that in on create view.
