i have develop one android application. Here i have to set the tabbar bottom on all android activities.how can i do.please give me solution for these. i have totally 10 activities
Solution 1:
Please write below code instead of your code for add multiple activities in one TabActivity, it will solve your problem.
ActivityStack.java
publicclassActivityStackextendsActivityGroup {
privateStack<String> stack;
@OverridepublicvoidonCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (stack == null)
stack = newStack<String>();
// start default activitypush("FirstStackActivity", newIntent(this, Tab_SampleActivity.class));
}
@OverridepublicvoidfinishFromChild(Activity child) {
pop();
}
@OverridepublicvoidonBackPressed() {
pop();
}
publicvoidpush(String id, Intent intent) {
Windowwindow = getLocalActivityManager().startActivity(id, intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP));
if (window != null) {
stack.push(id);
setContentView(window.getDecorView());
}
}
publicvoidpop() {
if (stack.size() == 1)
finish();
LocalActivityManager manager = getLocalActivityManager();
manager.destroyActivity(stack.pop(), true);
if (stack.size() > 0) {
Intent lastIntent = manager.getActivity(stack.peek()).getIntent();
Window newWindow = manager.startActivity(stack.peek(), lastIntent);
setContentView(newWindow.getDecorView());
}
}
}
TabActivity.java
publicclassTabActivityextendsTabActivity {
/** Called when the activity is first created. */@OverridepublicvoidonCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tab_screen);
TabHosttabHost= getTabHost();
Intentintent=newIntent().setClass(this, ActivityStack.class);
TabHost.TabSpecspec= tabHost.newTabSpec("tabId").setIndicator("Temp", getResources().getDrawable(R.drawable.home));
spec.setContent(intent);
tabHost.addTab(spec);
Intentintent1=newIntent().setClass(this, ActivityStack.class);
TabHost.TabSpecspec1= tabHost.newTabSpec("tabId").setIndicator("Temp", getResources().getDrawable(R.drawable.invoice));
spec1.setContent(intent1);
tabHost.addTab(spec1);
tabHost.setCurrentTab(0);
}
}
FirstActivity.java
publicclassFirstActivityextendsActivity {
@OverridepublicvoidonCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextViewtextView=newTextView(this);
textView.setText("Tab Sample Activity ");
textView.setOnClickListener(newView.OnClickListener() {
@OverridepublicvoidonClick(View v) {
Intentintent=newIntent();
intent.setClass(getParent(), SecondActivity.class);
ActivityStackactivityStack= (ActivityStack) getParent();
activityStack.push("SecondActivity", intent);
}
});
setContentView(textView);
}
}
SecondActivity.java
publicclassSecondActivityextendsActivity {
@OverridepublicvoidonCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextViewtextView=newTextView(this);
textView.setText("First Stack Activity ");
textView.setOnClickListener(newView.OnClickListener() {
@OverridepublicvoidonClick(View v) {
Intentintent=newIntent();
intent.setClass(getParent(), ThirdActivity.class);
ActivityStackactivityStack= (ActivityStack) getParent();
activityStack.push("ThirdActivity", intent);
}
});
setContentView(textView);
}
}
ThirdActivity.java
publicclassThirdActivityextendsActivity {
@OverrideprotectedvoidonCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stubsuper.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
}
Add Below XML files into your res/layout folder.
1) tab_screen.xml
<?xml version="1.0" encoding="utf-8"?><TabHostxmlns:android="http://schemas.android.com/apk/res/android"android:id="@android:id/tabhost"android:layout_width="fill_parent"android:layout_height="fill_parent" ><RelativeLayoutandroid:layout_width="fill_parent"android:layout_height="fill_parent"android:orientation="vertical"android:padding="3dp" ><FrameLayoutandroid:id="@android:id/tabcontent"android:layout_width="fill_parent"android:layout_height="fill_parent"android:layout_above="@android:id/tabs"android:layout_weight="1" /><TabWidgetandroid:id="@android:id/tabs"android:layout_width="fill_parent"android:layout_height="wrap_content"android:layout_alignParentBottom="true" /></RelativeLayout></TabHost>2) main.xml

Solution 2:
You can use this class for implementing the functionality you have specified.
import java.util.ArrayList;
import android.app.Activity;
import android.app.ActivityGroup;
import android.app.LocalActivityManager;
import android.content.Intent;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.Window;
publicclassTabActivityGroupextendsActivityGroup {
private ArrayList<String> mIdList;
@OverridepublicvoidonCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (mIdList == null)
mIdList = newArrayList<String>();
}
/**
* This is called when a child activity of this one calls its finish method.
* This implementation calls {@link LocalActivityManager#destroyActivity} on
* the child activity and starts the previous activity. If the last child
* activity just called finish(),this activity (the parent), calls finish to
* finish the entire group.
*/@OverridepublicvoidfinishFromChild(Activity child) {
LocalActivityManagermanager= getLocalActivityManager();
intindex= mIdList.size() - 1;
if (index < 1) {
finish();
return;
}
manager.destroyActivity(mIdList.get(index), true);
mIdList.remove(index);
index--;
StringlastId= mIdList.get(index);
IntentlastIntent= manager.getActivity(lastId).getIntent();
WindownewWindow= manager.startActivity(lastId, lastIntent);
setContentView(newWindow.getDecorView());
}
/**
* Starts an Activity as a child Activity to this.
*
* @param Id
* Unique identifier of the activity to be started.
* @param intent
* The Intent describing the activity to be started.
* @throws android.content.ActivityNotFoundException.
*/publicvoidstartChildActivity(String Id, Intent intent) {
Windowwindow= getLocalActivityManager().startActivity(Id,
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP));
if (window != null) {
mIdList.add(Id);
setContentView(window.getDecorView());
}
}
/**
* The primary purpose is to prevent systems before
* android.os.Build.VERSION_CODES.ECLAIR from calling their default
* KeyEvent.KEYCODE_BACK during onKeyDown.
*/@OverridepublicbooleanonKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
// preventing default implementation previous to// android.os.Build.VERSION_CODES.ECLAIRreturntrue;
}
returnsuper.onKeyDown(keyCode, event);
}
/**
* Overrides the default implementation for KeyEvent.KEYCODE_BACK so that
* all systems call onBackPressed().
*/@OverridepublicbooleanonKeyUp(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
onBackPressed();
returntrue;
}
returnsuper.onKeyUp(keyCode, event);
}
/**
* If a Child Activity handles KeyEvent.KEYCODE_BACK. Simply override and
* add this method.
*/@OverridepublicvoidonBackPressed() {
intlength= mIdList.size();
if (length > 1) {
Activitycurrent= getLocalActivityManager().getActivity(
mIdList.get(length - 1));
current.finish();
}
}
}
Create an intermediate activity as below by extending TabActivitygroup
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
publicclassInterMediateActivityextendsTabActivityGroup{
String TabID;
String TabName;
@Overridepublic void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stubsuper.onCreate(savedInstanceState);
TabID=getIntent().getStringExtra("TabID");
TabName=getIntent().getStringExtra("TabName");
Log.i("Tab from intermediate",""+TabID+" "+TabName);
filterTabs(TabID);
}
private void filterTabs(String TabID)
{
if(TabID.trim().equals("Home"))
{
startChildActivity("Options", new Intent(this,HomePage.class));
//TabsUtil.setTabIndicator(specTab,"Wall", null, tabView);
}
if(TabID.trim().equals("Menu"))
{
startChildActivity("Options", new Intent(this,MenuPage.class));
//TabsUtil.setTabIndicator(specTab,"Wall", null, tabView);
}
if(TabID.trim().equals("Gallery"))
{
Log.i("GALLERY check", "gallery check");
startChildActivity("Options", new Intent(this,GalleryPage.class));
}
if(TabID.trim().equals("Aboutus"))
{
startChildActivity("Options", new Intent(this,AboutUsPage.class));
}
if(TabID.trim().equals("Location"))
{
startChildActivity("Options", new Intent(this,LocationList.class));
}
if(TabID.trim().equals("Events"))
{
startChildActivity("Options", new Intent(this,EventsPage.class));
}
if(TabID.trim().equals("TipCalculator"))
{
startChildActivity("Options", new Intent(this,TipCalculatorPage.class));
}
if(TabID.trim().equals("Special"))
{
startChildActivity("Options", new Intent(this,SpecialPage.class));
}
if(TabID.trim().equals("NowRunning"))
{
startChildActivity("Options", new Intent(this,NowRunningPage.class));
}
if(TabID.trim().equals("ShowTimes"))
{
startChildActivity("Options", new Intent(this,ShowTimePage.class));
}
if(TabID.trim().equals("GpsCoupon"))
{
startChildActivity("Options", new Intent(this,GPSCouponPage.class));
}
if(TabID.trim().equals("UpcomingMovieNames"))
{
startChildActivity("Options", new Intent(this,UpcomingPage.class));
}
if(TabID.trim().equals("PriceListOfServices"))
{
startChildActivity("Options", new Intent(this,ServicesPage.class));
}
if(TabID.trim().trim().equals("NewsLetter"))
{
Log.i("newsletter check", "newsletter check");
startChildActivity("Options", new Intent(this,NewsLetter.class));
}
if(TabID.trim().trim().equals("Website"))
{
startChildActivity("Options", new Intent(this,WebSitePage.class));
}
}
}
And instead of setting the tabs from tabactivity directly you can set them inside the intermediate activity. Then call the Intermediate activity from the tabactivity.
Intent intent = newIntent(this, InterMediateActivity.class);
intent.putExtra("TabID", item.elementAt(0));
intent.putExtra("TabName", item.elementAt(1));
