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
to null
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?
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...
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!
