The text color does not change TabWidget

问题

I'm trying to change the TabWidget text color, without success, even though I've tried different way to change it (see code below.)

My background tabs is an image:

for (int i = 0; i < tabHost.getTabWidget().getTabCount(); i++) {
    tabHost.getTabWidget().getChildAt(i).setBackgroundColor(Color.TRANSPARENT); 
}

I do not know if this creates some sort of conflict with what I want to do now.

Solution1:

main.xml

....
    <TabWidget
        android:id="@android:id/tabs"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/tabbarbackground"
        android:tabStripEnabled="false"            
        style="@style/TabText"
        /> ....

style.xml

... <style name="TabText">
    <item name="android:textColor">@color/tab_text_color</item> </style> ....

tab_text_color.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_selected="true" android:textColor="#2daed9" />
    <item android:state_selected="false" android:color="#FFFFFF" />
</selector>

solution 2

for (int i = 0; i < tabHost.getTabWidget().getTabCount(); i++) {
    tabHost.getTabWidget().getChildAt(i).setBackgroundColor(Color.TRANSPARENT);         
    RelativeLayout rl = (RelativeLayout) tabHost.getTabWidget().getChildAt(i);
    TextView textView = (TextView) rl.getChildAt(1);
    textView.setTextColor(R.color.tab_text_color);
}

tab_text_color.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_selected="true" android:textColor="#2daed9" />
    <item android:state_selected="false" android:color="#FFFFFF" /> </selector>

but neither solution works.

However, if I change the second solution

textView.setTextColor (R.color.tab_text_color);

to

textView.setTextColor (Color.parseColor ("# ....")); 

It works, except this solution does not change the color of text when I click on it.

Thanks.

I was able to solve, the solution isn't elegant but works. I hope who is usefull for somebody:

First, I must set init color for the textview of all tabs:

for (int i = 0; i < tabHost.getTabWidget().getTabCount(); i++) {
    vg = (ViewGroup) getTabHost().getTabWidget().getChildAt(i);
    tv = (TextView) vg.getChildAt(1);
    tv.setTypeface(font);
    if (i == 0) {
        tv.setTextColor(Color.parseColor("#2daed9"));
        Currentab = 0;
    } else {
        tv.setTextColor(R.color.GrisOscuro);
    }
}

And then, I set in the override method ontabchanged, the change color for each tab. The tab pulsed are i (getTabHost().getCurrentTab()). And the last tab who I press is Currentab.

getTabHost().setOnTabChangedListener(new OnTabChangeListener() {
    public void onTabChanged(String tabId) {
        int i = getTabHost().getCurrentTab();
        if (Currentab != i) {
            vg = (ViewGroup) getTabHost().getTabWidget()
                    .getChildAt(Currentab);
            tv = (TextView) vg.getChildAt(1);
            tv.setTextColor(R.color.GrisOscuro);

            Currentab = i;
            vg = (ViewGroup) getTabHost().getTabWidget()
                    .getChildAt(i);
            tv = (TextView) vg.getChildAt(1);
            tv.setTextColor(Color.parseColor("#2daed9"));
        }
    }
});

Sorry for my english, I hope is useful for somebody =) Bye! ;D

In your solution 2:

TabWidget tabwidget=mTabHost.getTabWidget();
for(int i=0;i<tabwidget.getChildCount();i++){
    TextView tv=(TextView) tabwidget.getChildAt(i).findViewById(android.R.id.title);
    tv.setTextColor(this.getResources().getColorStateList(R.color.tab_text_xml));
}

回答3:

try to write this methode:

public void onTabChanged(String tabId) {

for(int i=0;i<tabHost.getTabWidget().getChildCount();i++)
{
TextView tv = (TextView) tabhost.getTabWidget()
.getChildAt(i).findViewById(R.id.your_text_id);
    tv.setTextColor(#FFFFFF);

}

TextView tv = (TextView)    tabHost.getTabWidget().
getChildAt(tabHost.getCurrentTab()).findViewById(R.id.your_text_id);

tv.setTextColor(#2daed9);
}
