Android app using TabHost with Multiple Maps causing issue - android

I am using TabHost in my application and I need to show 2 maps in 2 different tabs. I have been able to integrate maps but the problem is when I move from one tab to another the map hangs/stucks and does not respond i.e. maps only works on one of the screen
Below is xml and class for my main layout which has TabHost
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#ff0000" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#ff0000"
>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#f00"
android:foregroundGravity="top"
android:layout_above="#android:id/tabs"
/>
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="#fff"

>
</TabWidget>
</RelativeLayout>
</TabHost>
package com.cotechnica.alps;
import android.os.Bundle;
import android.app.Activity;
import android.app.TabActivity;
import android.content.Intent;
import android.content.res.Resources;
import android.view.Menu;
import android.widget.TabHost;
import com.ankitkedia.alps.R;
public class Main extends TabActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Resources res = getResources();
TabHost tabHost = getTabHost();
TabHost.TabSpec spec;
Intent intent;
// Create an Intent to launch an Activity for the tab (to be reused)
intent = new Intent().setClass(this, Map1.class);
spec = tabHost.newTabSpec("home").setIndicator("Map1",
getResources().getDrawable(android.R.drawable.star_on)).setContent(intent);
tabHost.addTab(spec);
// Do the same for the other tabs
intent = new Intent().setClass(this, Map2.class);
spec = tabHost.newTabSpec("rescue").setIndicator("Map2",
getResources().getDrawable(android.R.drawable.star_big_off)
).setContent(intent);
tabHost.addTab(spec);
}
#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;
}
}
I have seen many people are facing same issue but there is no proper solution available for it.
Any help would be appreciated, I can sent the sample project source if required

Ankit

This guy has a great solution

deprecated TabActivity in android no errors but the application unfortunately stopped when clicking button

PS. i am new in android and java programming.
i have this problem in my application it crashes when i clicked on my intent button which handles tab activity (the deprecated one), there are no errors with some warnings but i can't seem to figure out what i am doing wrong.
here is the code.
InformationActivity.class
import android.app.TabActivity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.TabHost;
import android.widget.TabHost.TabSpec;
public class InformationActivity extends TabActivity
{
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_information);
// create the TabHost that will contain the Tabs
TabHost tabHost = (TabHost)findViewById(R.id.tabhost);
TabSpec tab1 = tabHost.newTabSpec("First Tab");
TabSpec tab2 = tabHost.newTabSpec("Second Tab");
// Set the Tab name and Activity
// that will be opened when particular Tab will be selected
tab1.setIndicator("Tab1");
tab1.setContent(new Intent(this,OfflineTab.class));
tab2.setIndicator("Tab2");
tab2.setContent(new Intent(this,OnlineTab.class));
/** Add the tabs to the TabHost to display. */
tabHost.addTab(tab1);
tabHost.addTab(tab2);
}
}
OfflineTab.class
import android.app.Activity;
import android.os.Bundle;
import android.view.Gravity;
import android.widget.TextView;
public class OfflineTab extends Activity
{
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
TextView tv=new TextView(this);
tv.setTextSize(25);
tv.setGravity(Gravity.CENTER_VERTICAL);
tv.setText("Contains R.E.D. e - Kit Offline module");
setContentView(tv);
}
}
OnlineTab.class
import android.app.Activity;
import android.os.Bundle;
import android.view.Gravity;
import android.widget.TextView;
public class OnlineTab extends Activity
{
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
TextView tv=new TextView(this);
tv.setTextSize(25);
tv.setGravity(Gravity.CENTER_VERTICAL);
tv.setText("This Is Tab2 Activity");
setContentView(tv);
}
}

The log said:
java.lang.RuntimeException: Your content must have a TabHost whose id attribute is 'android.R.id.tabhost'
So just don't define a new id for tabhost:
activity_information.xml
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"

</TabWidget>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
</FrameLayout>
</LinearLayout>
</TabHost>
onCraete() of InformationActivity
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_information);
// create the TabHost that will contain the Tabs
TabHost tabHost = getTabHost(); // <- get tabhost by this
TabSpec tab1 = tabHost.newTabSpec("First Tab");
TabSpec tab2 = tabHost.newTabSpec("Second Tab");
// Set the Tab name and Activity
// that will be opened when particular Tab will be selected
tab1.setIndicator("Tab1");
tab1.setContent(new Intent(this,OfflineTab.class));
tab2.setIndicator("Tab2");
tab2.setContent(new Intent(this,OnlineTab.class));
/** Add the tabs to the TabHost to display. */
tabHost.addTab(tab1);
tabHost.addTab(tab2);
}
And it worked!

ActionButton/ActionBar does not showup in TabHost method

I'm trying to have a different action bar for each new tab (activity) in my project
I have created my first Activity and put it as a tab in my Main Activity
my first activity (tab) has the action button ( Start ) in the action bar of its activity
somehow nothing show up in the action bar for this tab
and if so I would to put more activities (tabs) no action bar/buttons will be shown
there is no error in my logcat
this is my code :

super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TabHost tabHost = getTabHost();
// Tab for activity1
TabSpec activity1 = tabHost.newTabSpec("Photos");
activity1.setIndicator("Photos", getResources().getDrawable(R.drawable.icon_photos_tab));

you need to add the Action buttons in the main activity (where the tabs are hosted) NOT in the tab activiy.
And later manage them in the tab activity by using
getParent().getActionBar()
and also..
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getParent().getMenuInflater().inflate(R.menu.home_tabs, menu);
//getMenuInflater().inflate(R.menu.home_tabs, menu);
return true;
}

Custom TabWidget Android Tab Indicator

Okay, so i am making an android app that has tabs, now my problem is that the tab widget isn't uniform across the diffrent android versions or devices.
I want to make it to be the same on any android this is my tab activity
import android.app.TabActivity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.TabHost;
import android.widget.TabHost.TabSpec;
public class Cook extends TabActivity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.cook_layout);
TabHost tabHost = getTabHost();
// Tab for Snacks
TabSpec snackspec = tabHost.newTabSpec("Snacks");
// setting Title and Icon for the Tab
snackspec.setIndicator("Snacks", getResources().getDrawable(R.drawable.cook_icon_tab_snacks));
Intent snacksIntent = new Intent(this, Cook_tab_snacks.class);
snackspec.setContent(snacksIntent);
// Tab for Mains
TabSpec mainspec = tabHost.newTabSpec("Mains");
mainspec.setIndicator("Mains", getResources().getDrawable(R.drawable.cook_icon_tab_snacks));
Intent mainsIntent = new Intent(this, Cook_tab_mains.class);
mainspec.setContent(mainsIntent);
// Tab for Desserts
TabSpec dessertspec = tabHost.newTabSpec("Desserts");
dessertspec.setIndicator("Desserts", getResources().getDrawable(R.drawable.cook_icon_tab_snacks));
Intent dessertsIntent = new Intent(this, Cook_tab_desserts.class);
dessertspec.setContent(dessertsIntent);
// Adding all TabSpec to TabHost
tabHost.addTab(snackspec); // Adding snacks tab
tabHost.addTab(mainspec); // Adding mains tab
tabHost.addTab(dessertspec); // Adding desserts tab
}
}
I also have my XML layout :
<?xml version="1.0" encoding="UTF-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
<FrameLayout
android:id="#android:id/tabcontent"
android:background="#drawable/gradient_bg"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
</LinearLayout>
I made a new indicator xml which is like the main android tab indicator v4
I followed and searched alot of blogs , i couldn't find my answer ...
I really want to make the android tabs uniform across all android versions and to make the colors nice , since orange and yellow dont really fit with the color theme in my app
Help please!!!!
I cant seem to find a way to fix it...
Cheers
okay i found a solution.
here is the code:
import android.app.TabActivity;
import android.content.Intent;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageView;
import android.widget.LinearLayout.LayoutParams;
import android.widget.TabHost;
import android.widget.TabHost.TabSpec;
public class Cook extends TabActivity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.cook_layout);
TabHost tabHost = getTabHost();
// Tab for Snacks
TabSpec snackspec = tabHost.newTabSpec("Snacks");
// setting Title and Icon for the Tab
snackspec.setIndicator(makeTabIndicator(getResources().getDrawable(R.drawable.cook_icon_tab_snacks)));
Intent snacksIntent = new Intent(this, Cook_tab_snacks.class);
snackspec.setContent(snacksIntent);
// Tab for Mains
TabSpec mainspec = tabHost.newTabSpec("Mains");
mainspec.setIndicator(makeTabIndicator( getResources().getDrawable(R.drawable.cook_icon_tab_snacks)));
Intent mainsIntent = new Intent(this, Cook_tab_mains.class);
mainspec.setContent(mainsIntent);
// Tab for Desserts
TabSpec dessertspec = tabHost.newTabSpec("Desserts");
dessertspec.setIndicator(makeTabIndicator( getResources().getDrawable(R.drawable.cook_icon_tab_snacks)));
Intent dessertsIntent = new Intent(this, Cook_tab_desserts.class);
dessertspec.setContent(dessertsIntent);
// Adding all TabSpec to TabHost
tabHost.addTab(snackspec); // Adding snacks tab
tabHost.addTab(mainspec); // Adding mains tab
tabHost.addTab(dessertspec); // Adding desserts tab
}
//making the tab view:
private View makeTabIndicator(Drawable drawable){
ImageView Tabimage = new ImageView(this);
LayoutParams LP = new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT,1);
LP.setMargins(1, 0, 1, 0);
Tabimage.setLayoutParams(LP);
Tabimage.setImageDrawable(drawable);
Tabimage.setBackgroundResource(R.drawable.tabview);
return Tabimage;
}}
I dont know weather or not i need the cook_layout anymore i'll see if i can remove it or leave it later... right now i just want to get it all working and later i'll come round by for a clean and tiding up
hope that helps you guys out there that stumble upon this question! cheers

Getting a False return from listview

I am getting a false return when implementing a listview within a framelayout/tab layout. For the life of me I can't seem to figure out why I am getting a false return on my app when implementing a listview. The code works on a external project but I cant seem to intergrate it into this one. I will list the main activity groups used within the project and the xml file for the page that the string is meant to appear on. Sorry its alot of code but this has been driving me insane over the last few days cause it should be relatively simple.
The xml layout files are held in framelayout coding within the main.xml(which is not shown) so have I got the ID wrong when referencing? Any help to solve this problem would be amazing as I know its a really simple solution that Im just missing. Thanks guys.
If I havnt explained it well a picturee of the error is below
View the page here http://i41.tinypic.com/do04ee.png
Their are no log errors.
Main Activity
(Please note I have removed code to make it more relavant and clear and to show the links from activity to activity)
package workout.fitty;

#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Resources res = getResources(); // Resource object to get Drawables
TabHost tabHost = getTabHost(); // The activity TabHost
TabHost.TabSpec spec; // Resusable TabSpec for each tab
Intent intent; // Reusable Intent for each tab
// More
**intent = new Intent().setClass(this, MoreActivity.class);
spec = tabHost.newTabSpec("songs").setIndicator("More",
res.getDrawable(R.drawable.tab_more))
.setContent(intent);
tabHost.addTab(spec);**
tabHost.setCurrentTab(1);
}
}

}
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
String item = (String) getListAdapter().getItem(position);
Toast.makeText(this, item + " selected", Toast.LENGTH_LONG).show();
}
}

change your:

in
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
R.layout.more_layout, values);

Android: Moving tabs to bottom causes the app to crash

i use this tutorial http://developer.android.com/resources/tutorials/views/hello-tabwidget.html to create tabs which opens new intents. however, the tabs in the tutorials are located on the top, so I followed this solution here https://stackoverflow.com/a/2710404/301584 to move the tabs to bottom (basically i just move the TabWidget to be after FrameLayout in the xml file, modify the neccessary layout_height and add layout_weight, as suggested by the solution on the link). the problem is, my apps will always forced close when I did this. here's the error reported by logcat

}
and my main.xml file
<?xml version="1.0" encoding="utf-8"?>

and my tab1.java (tab2.java is the same)
package com.geoflex.trymasak;
import android.app.Activity;
import android.os.Bundle;

public class Tab1 extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView tv = new TextView(this);
tv.setText("This is tab 1");
setContentView(tv);
}
}
Try this to set Tabs in the bottom :
<?xml version="1.0" encoding="utf-8"?>
<TabHost

<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="#android:id/tabs"
/>
</RelativeLayout>
</TabHost>
And use the following code for your main activity (thats extends the TabActivity):
public class TabTestActivity extends TabActivity {
/** Called when the activity is first created. */
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TabHost tabHost = getTabHost(); // The activity TabHost
TabHost.TabSpec spec; // Reusable TabSpec for each tab
Intent intent; // Reusable Intent for each tab
intent = new Intent().setClass(this,Tab1.class);
spec = tabHost.newTabSpec("projects").setIndicator("Projects",
getResources().getDrawable(R.drawable.ic_launcher))
.setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this,Tab2.class);
spec = tabHost.newTabSpec("news").setIndicator("News",
getResources().getDrawable(R.drawable.ic_launcher))
.setContent(intent);
tabHost.addTab(spec);
tabHost.setCurrentTab(0);
}
}
Try this
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:paddingBottom="#dimen/tab_space_top"
android:layout_width="fill_parent" android:paddingLeft="#dimen/tab_space_gap"
android:layout_height="fill_parent" android:paddingRight="#dimen/tab_space_gap" >
<LinearLayout android:id="#+id/tab_relative_layout" android:orientation="vertical"
android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="#drawable/background">
<FrameLayout android:id="#android:id/tabcontent" android:layout_weight="1"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:layout_below="#android:id/tabs"></FrameLayout>
<TabWidget android:id="#android:id/tabs"
android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="0"></TabWidget>
</LinearLayout>
RelativeLayout rllf = (RelativeLayout) tw.getChildAt(0);
I think this is supposed to be casted to Framelayout according to your logs.
set in fragment
if(getActivity() != null && isAdded) {
//do your operation
}
