Android TabWidget detect click on current tab
Solution 1
I think I have found a solution, here follows a sample code:
intent = new Intent(this, HomeGroup.class);
View tab1 = _inflater.inflate(R.layout.custom_tab_1,null);
homeTab.setTag("Tab1");
spec = tabHost.newTabSpec("Tab1").setIndicator(tab1).setContent(intent);
tabHost.addTab(spec);
View tab2 = _inflater.inflate(R.layout.custom_tab_2,null);
homeTab.setTag("Tab2");
spec = tabHost.newTabSpec("Tab2").setIndicator(tab2).setContent(intent);
tabHost.addTab(spec);
View tab3 = _inflater.inflate(R.layout.custom_tab_3,null);
homeTab.setTag("Tab3");
spec = tabHost.newTabSpec("Tab3").setIndicator(tab3).setContent(intent);
tabHost.addTab(spec);
tabHost.setOnTabChangedListener(this);
//click on seleccted tab
int numberOfTabs = tabHost.getTabWidget().getChildCount();
for(int t=0; t<numberOfTabs; t++){
tabHost.getTabWidget().getChildAt(t).setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if(event.getAction()==MotionEvent.ACTION_UP){
String currentSelectedTag = MainTab.this.getTabHost().getCurrentTabTag();
String currentTag = (String)v.getTag();
Log.d(this.getClass().getSimpleName(), "currentSelectedTag: " + currentSelectedTag + " currentTag: " + currentTag);
if(currentSelectedTag.equalsIgnoreCase(currentTag)){
MainTab.this.getTabHost().setCurrentTabByTag(currentTag);
String newSelectedTabTag = MainTab.this.getTabHost().getCurrentTabTag();
if(newSelectedTabTag.toLowerCase().indexOf("tab1")!=-1){
//do smthg
}else if(newSelectedTabTag.toLowerCase().indexOf("tab1")!=-1){
//do smthg
}else if(newSelectedTabTag.toLowerCase().indexOf("tab3")!=-1){
//do smthg
}
return true;
}
}
return false;
}
});
}
Probably it is possible to improve it, but this does the work for me!
Solution 2
After gothrough many solutions for tab listener, I have found very simple solution...
getTabHost().setOnTabChangedListener(new OnTabChangeListener() {
@Override
public void onTabChanged(String tabId) {
int i = getTabHost().getCurrentTab();
Log.i("@@@@@@@@ ANN CLICK TAB NUMBER", "------" + i);
if (i == 0) {
Log.i("@@@@@@@@@@ Inside onClick tab 0", "onClick tab");
}
else if (i ==1) {
Log.i("@@@@@@@@@@ Inside onClick tab 1", "onClick tab");
}
}
});

After a lot of thinking about this, the solution ended up being easier than I thought. What I did was just create a new child class that extends TabHost and override the setCurrentTab method like so:
package com.mycompany.Views;
import android.content.Context;
import android.util.AttributeSet;
import android.widget.TabHost;
import android.widget.Toast;
public class ReclickableTabHost extends TabHost {
public ReclickableTabHost(Context context) {
super(context);
}
public ReclickableTabHost(Context context, AttributeSet attrs) {
super(context, attrs);
}
@Override
public void setCurrentTab(int index) {
if (index == getCurrentTab()) {
// FIRE OFF NEW LISTENER
} else {
super.setCurrentTab(index);
}
}
}
To use your new class instead of the typical TabHost just edit your layout xml file with:
<FrameLayout
android:layout_height="match_parent"
android:layout_width="0dip"
android:layout_weight=".8">
<com.myCompany.Views.ReclickableTabHost
android:id="@android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:visibility="gone">
<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"
android:background="@drawable/tab_unselected_holo"/>
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
</FrameLayout>
</LinearLayout>
</com.myCompany.Views.ReclickableTabHost>
Hope this helps...

Ugly fix:IN the onClickListener put :
tabHost.SetCurrentTab(OtherTab);
tabHost.SetCurrentTab(CurrentTab);
Where for index of Other Tab I use my simplest view under the tabs.
P.S. Customers always want their apps to be different :)
This is the code that I use (I have only 2 tabs Tab1 and Tab2):
getTabWidget().getChildAt(1).setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Log.d(TAG,"1"+getTabHost().getCurrentTabTag());
if (getTabHost().getCurrentTabTag().equals("Tab2")) {
Log.d(TAG,"2");
tabHost.setCurrentTab(0);
tabHost.setCurrentTab(1);
} else {
tabHost.setCurrentTab(1);
}
}
});
Solution 5
The problem here is that setOnTabChangedListener
does not fire when clicking on the selected tab, and if you set an OnClickListener
on the tab, you lose the normal tab behavior.
So an easy solution is to put OnClickListener
on the tab, and inside it, set programatically that this is the current tab.
With TabHost
:
getTabWidget().getChildAt(0).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// custom code
tabHost.setCurrentTab(0);
}
});
With TabLayout
tabLayout.getTabAt(0)setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
// custom code
TabLayout.Tab tab = tabLayout.getTabAt(0);
tab.select();
}
}
});

I am trying to find way to be able to fire an onclick event on a tab when this tab is the current tab.
I did try this way (among several other) with no success thou.
public void onTabChanged(String tabId) { Log.d(this.getClass().getName(), ">>>>>>>>>>>>>>>>>>>>>>>> tabId: " + tabId); int tabs = getTabWidget().getChildCount(); Log.d(this.getClass().getName(), "tabs: " + tabs); for(int i=0; i<tabs; i++){ View tab = getTabWidget().getChildAt(i); if(i==tabHost.getCurrentTab()){ Log.d(this.getClass().getName(), "tab: " + i); tab.setOnClickListener(this); }else{ tab.setOnClickListener(null); tab.getOnFocusChangeListener(); } } }
the point is that I set the
onClickListener
tonull
so, the next time I click on a tab nothing happens, but I would like to have the normal tab behavior.Any idea there outside?

0m4r over 13 yearswhat do you mean with " Where for index of Other Tab I use my simplest view under the tabs."?
-
0m4r over 13 yearsI have been trying your solution but I still have the problem that overrriding the default onClick event on the tab I override the default behavior... and setting it to null remove the onClick event at all.... so, thanks for your help but I think I can't use your solution unless I rewrite the whole onClick event for the tab :/
-
0m4r over 13 yearsuseful with two tabs, with more than two I would not know how to manage it :) But thanks anyhow!
-
dhaag23 over 11 yearsThis doesn't solve the OPs problem: this only gets called when the tab has changed and not when clicking the same tab.
-
dhaag23 over 11 yearsSeems like the most reliable solution. Thanks Steve.

hackp0int about 11 yearsThanks man, you helped me to finish one long and crazy project

neobie almost 11 yearsv.getTag() return null for me.
-
Moritz almost 11 yearsGreat answer. I added
public interface OnReClickListener { public void onReClick(int index); }
an and ivarprivate OnReClickListener onReClickListener;
(plus getters and setters) as well as this code to fire off the listener:if (null != onReClickListener) { onReClickListener.onReClick(index);}
Hope that helps. -
Admin over 10 years@ 0m4r ........ can you look into this question ..... stackoverflow.com/q/19269322/2825729

Ria over 10 years@ 0m4r - Can you please tell me what refers homeTab?
-
0m4r over 10 years@Ria homeTab is the view to display when i press a tab button (probably in the snippet above, the fact that I have more then one homeTab is a cut&past error....)
-
Ria over 10 years@ 0m4r - Thanks dude.

Zubair Ahmed over 10 years@Chirag_CID great answer :-), I have been stuck for last 3 days and this answer solved my exact problem ;)
-
Jimmar over 9 yearsoverride the onTouchListener instead and return false inside onTouch, Using onClick will cause the tabs to stop changing
-
Oleksandr over 8 yearsIt is also important to add check isShown() before notifying listener. Because android calls setCurrentTab if user locks/unlocks device.
-
Huy Tower over 7 years@dhaag23 : You should disable current tab to avoid click again. It would be more familiar with users.
-
dhaag23 over 7 years@TranDucHuy - a disabled tab may not be what users want or expect - it all depends on the use case, and as I mentioned, it's not what was asked.

Yuchen about 7 yearsHey @AmiAram, thanks for your edit. Unfortunately, it didn't go through. But it is good suggestion and I changed my answer with that!
