I'm new in Android. I wanna create an application that shows an action bar with fixed tabs. I've reached to do this.
The problem is that the tabs don`t fit in the same view.
This is my Main Activity:
package com.pestana.pestana;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.MenuInflater;
import android.app.ActionBar;
import android.app.Fragment;
public class MainActivity extends Activity {
// Declare Tab Variable
ActionBar.Tab Tab1, Tab2, Tab3,Tab4;
Fragment fragmentTab1 = new FragmentTab1();
Fragment fragmentTab2 = new FragmentTab2();
Fragment fragmentTab3 = new FragmentTab3();
Fragment fragmentTab4 = new FragmentTab4();
#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().setIcon(R.drawable.tab1);
Tab2 = actionBar.newTab().setText("Tab2");
Tab3 = actionBar.newTab().setText("Tab3");
Tab4 = actionBar.newTab().setText("Tab4");
// Set Tab Listeners
Tab1.setTabListener(new TabListener(fragmentTab1));
Tab2.setTabListener(new TabListener(fragmentTab2));
Tab3.setTabListener(new TabListener(fragmentTab3));
Tab4.setTabListener(new TabListener(fragmentTab4));
// Add tabs to actionbar
actionBar.addTab(Tab1);
actionBar.addTab(Tab2);
actionBar.addTab(Tab3);
actionBar.addTab(Tab4);
}
#Override public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main, menu);
return true; /** true -> el menú ya está visible */
}
}
And this is the layout
`
<?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="fill_parent"
android:layout_height="fill_parent" />
`
I've created also 4 classes for FragmentTab1... FragmentTab4,
FragmentTab1
package com.pestana.pestana;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.app.Fragment;
public class FragmentTab1 extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragmenttab1, container, false);
return rootView;
}
}
FragmentTab2
package com.pestana.pestana;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.app.Fragment;
public class FragmentTab2 extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragmenttab2, container, false);
return rootView;
}
}
FragmentTab3
package com.pestana.pestana;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.app.Fragment;
public class FragmentTab3 extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragmenttab3, container, false);
return rootView;
}
}
FragmentTab4
package com.pestana.pestana;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.app.Fragment;
public class FragmentTab4 extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragmenttab4, container, false);
return rootView;
}
}
TabListener.java
package com.pestana.pestana;
import android.app.ActionBar;
import android.app.ActionBar.Tab;
import android.app.Fragment;
import android.app.FragmentTransaction;
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
}
}
4 XML layout for each fragment this is an example, just have to change Fragment1 for each XML
<?xml version="1.0" encoding="utf-8"?>
<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" >
<TextView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:text="#string/Fragment1" />
</RelativeLayout>
I am stuck for 3 days, any help please?? With the same code can I implement a swipe view with the different tabs?? Thanks in advance
Check the documentation (Creating Swipe Views with Tabs), you can download a working example of how to do exactly what you want.

I encounter an issue with one of my fragments which does not trigger at all onCreateOptionsMenu() unlike my other fragments. There is no exception neither or any particular trace and I use the setHasOptionsMenu(true) method.
package fr.test.test.fragment;
import android.app.ActionBar;
import android.support.v4.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.View;
import android.view.ViewGroup;
import fr.test.test.MainActivity;
import fr.test.test.listener.FragmentTabListener;
import fr.test.test.R;
public class TestFragment extends Fragment {
private ActionBar.Tab Tab1, Tab2;
private Fragment fragmentTab1;
private Fragment fragmentTab2;
private ActionBar actionBar;
public TestFragment() {
fragmentTab1 = new Fragment1();
fragmentTab2 = new Fragment2();
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_messages, container, false);
setHasOptionsMenu(true);
actionBar = getActivity().getActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
Tab1 = actionBar.newTab().setText(R.string.title_fragment1);
Tab2 = actionBar.newTab().setText(R.string.title_fragment2);
Tab1.setTabListener(new FragmentTabListener(getActivity(), fragmentTab1));
Tab2.setTabListener(new FragmentTabListener(getActivity(), fragmentTab2));
actionBar.removeAllTabs();
actionBar.addTab(Tab1);
actionBar.addTab(Tab2);
return rootView;
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
System.out.println("onCreateOptionsMenu TRIGGER ME PLZ :( ");
inflater.inflate(R.menu.global, menu);
}
}
The problem does not come from my menu because my other fragments triggers this event, that's why I do not understand a thing on this case. I use exactly the same logic but with the standart navigation from the ActionBar instead of tabs. Any ideas ?
Thanks for watching,
Regards.
I have 2 fragments . In the first fragment there is a button which on clicking will move to 2 nd fragment. When the screen is rotated in this 2nd fragment,after orientation change I see first fragment instead of 2nd fragment. Can anyone help me in solving this issue?

Can anyone help me in solving this issue.
Try this-
FragmentManager fragmentManager =null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_orientation);
if(fragmentManager==null){
fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction =
fragmentManager.beginTransaction();
fragmentTransaction.replace(android.R.id.content, new Fragmentone()).commit();
}
}
or else
use this in manifest's activity tag-
android:configChanges="orientation"
i use "Actionbarsherlock" in my project
First i import "Actionbarsherlock" in my project then delete folder "libs"

Please help me to solve this problem
bro remove your email adress from the question.Now coming to your question your actionbar should be an object of supportActionbar.Change the getActionBar() to getSupportActionBar()l.And secondly,your main activity should extend sherlockActivity.Lastly,change the importation from the android actionbar to the sherlock actionbar
Can anyone help me here? And yes, I know using the error log like this is bad practice. The fragment below does not produce an exception (yet), but it doesn't show at all:
package com.tom.pws;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class MAF extends Fragment {
public View OnCreateView(LayoutInflater inflater,
ViewGroup container, Bundle args) {
View view = inflater.inflate(R.layout.activity_maf, container, false);
Log.e("reached AGAIN", "yay");
return view;
}
}
Here's the main activity:
package com.tom.pws;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentTransaction;
import android.util.Log;
import android.view.Menu;
public class MainActivity extends FragmentActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Log.e("reached", "yay");
if (savedInstanceState != null) {
return;
}
MAF maf = new MAF();
FragmentTransaction fm = getSupportFragmentManager().beginTransaction();
fm.add(R.id.lodsamone, maf);
fm.commit();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
activity_maf.xml:
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/text_body"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:text="#string/hello_world" />
activity_main.xml:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/lodsamone"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
It seems that OnCreateView will never be reached. What am I missing here?
MAF maf = new MAF();
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.lodsamone, maf).commit();
Is OnCreateView(...) correct?
It is
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
I have run into an obstacle where my tabbed layouts are overlapping their content. I am currently creating an Android app. This is when the first tab is opened. (link to picture below):
This is what happens when I open the second tab (link to picture below):
You might notice that the button that says "Button" is overlapping the MainActivity. That is my problem. I don't want them to overlap. I just want the button to show the other activity (no overlapping). Here is part of my MainActivity.java code:
package com.example.currencyconverter;
import android.app.ActionBar;
import android.app.Activity;
import android.app.Fragment;
import android.app.ProgressDialog;
import android.os.Bundle;
import android.os.StrictMode;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.View;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
addListenerOnButton();
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
ActionBar actionBar = getActionBar();
actionBar.setSubtitle("Created By Rohit Nandakumar");
actionBar.setTitle("Currency Converter");
// Specify that tabs should be displayed in the action bar.
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
ActionBar.Tab Frag1 = actionBar.newTab().setText("Converter");
ActionBar.Tab Frag2 = actionBar.newTab().setText("Currencies");
ActionBar.Tab Frag3 = actionBar.newTab().setText("News");
Fragment fragment1 = new Fragment1();
Fragment fragment2 = new Fragment2();
Fragment fragment3 = new Fragment3();
Frag1.setTabListener(new MyTabsListener(fragment1));
Frag2.setTabListener(new MyTabsListener(fragment2));
Frag3.setTabListener(new MyTabsListener(fragment3));
actionBar.addTab(Frag1);
actionBar.addTab(Frag2);
actionBar.addTab(Frag3);
Here is Fragment1.java code:
package com.example.currencyconverter;
import android.os.Bundle;
import android.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class Fragment1 extends Fragment{
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.activity_main, container, false);
}
}
Here is my Fragment2.java code:
package com.example.currencyconverter;
import android.os.Bundle;
import android.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class Fragment2 extends Fragment {
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment2, container, false);
}
}
Here is my MyTabsListener.java file:
package com.example.currencyconverter;
import android.app.ActionBar.Tab;
import android.app.ActionBar.TabListener;
import android.app.Fragment;
import android.app.FragmentTransaction;
public class MyTabsListener implements TabListener {
public Fragment fragment;
public MyTabsListener(Fragment fragment) {
this.fragment = fragment;
}
#Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
}
#Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
ft.replace(R.id.fragment_container, fragment);
}
#Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
}
}
What is the problem? What am I doing wrong. I have searched Google, but I could not find the solution. Any help is greatly appreciated.
