Sorry for the possibly confusing title
So I'm using ViewPagerIndicator, which is a library commonly used for tabs before TabLayout was released in 5.0. In this library, tabs are views that extend TextView, that accepted a custom attribute for styling.
//An inner class of TabPageLayout
private class TabView extends TextView {
private int mIndex;
public TabView(Context context) {
super(context, null, R.attr.vpiTabPageIndicatorStyle); //<--custom attribute
}
// ...
}
vpi__attrs.xml
<resources>
<declare-styleable name="ViewPagerIndicator">
...
<!-- Style of the tab indicator's tabs. -->
<attr name="vpiTabPageIndicatorStyle" format="reference"/>
</declare-styleable>
...
With this setup, when I used TabPageLayout in my own project, I could define the style of the text like this
<!--This is styles.xml of my project -->
<style name="MyStyle.Tabs" parent="MyStyle" >
<item name="vpiTabPageIndicatorStyle">@style/CustomTabPageIndicator</item>
</style>
<style name="CustomTabPageIndicator">
<item name="android:gravity">center</item>
<item name="android:textStyle">bold</item>
<item name="android:textSize">@dimen/secondary_text_size</item>
...
</style>
The following style would be applied to the Activity, and it would override the default vpiTabPageIndicator in the ViewPagerIndicator library.
My problem now is that I needed to make more customization to TabView than a TextView would allow, so I created a new inner class called "TabLayoutWithIcon" that extends LinearLayout and includes a TextView.
private class TabViewWithIcon extends LinearLayout {
private int mIndex;
private TextView mText;
public TabViewWithIcon(Context context) {
super(context, null, R.attr.vpiTabPageIndicatorStyle);
//setBackgroundResource(R.drawable.vpi__tab_indicator);
mText = new TextView(context);
}
...
public void setText(CharSequence text){
mText.setText(Integer.toString(mIndex) + " tab");
addView(mText);
}
public void setImage(int iconResId){
mText.setCompoundDrawablesWithIntrinsicBounds(iconResId, 0, 0, 0);
mText.setCompoundDrawablePadding(8); //Just temporary
}
Now the same custom style is being applied to a LinearLayout, but I also want to style the child TextView. How can I do this?
Of course, I could also just pass in a style for the TextView programatically inside TabViewWithIcon,like
mText.setTextAppearance(context, R.style.CustomTabTextStyle);
but then I would have to write my custom style inside the library, which I shouldn't be doing.
Do I need to redefine some attributes or something? Am I approaching this incorrectly?
Im an idiot, I just have pass the custom TextView style into the TextView
public TabView(Context context) {
super(context, null, R.attr.vpiTabPageIndicatorStyle);
//setBackgroundResource(R.drawable.vpi__tab_indicator);
mText = new TextView(context, null, R.attr.vpiTabPageIndicatorStyle);
}
