android.support.design.widget.TabLayout的自定义字体

Question

如何使用属于android.support.design.widget包的Tablayout类的自定义字体？我正在使用它来实现快速返回视图功能.

Answer 1

从23.2.0开始,setTabsFromPagerAdapter已被弃用,但是使用Andreyua的答案的修改版本,您可以使用setupWithViewPager.

    @Override
public void setupWithViewPager(ViewPager viewPager)
{
    super.setupWithViewPager(viewPager);

    if (mTypeface != null)
    {
        this.removeAllTabs();

        ViewGroup slidingTabStrip = (ViewGroup) getChildAt(0);

        PagerAdapter adapter = viewPager.getAdapter();

        for (int i = 0, count = adapter.getCount(); i < count; i++)
        {
            Tab tab = this.newTab();
            this.addTab(tab.setText(adapter.getPageTitle(i)));
            AppCompatTextView view = (AppCompatTextView) ((ViewGroup) slidingTabStrip.getChildAt(i)).getChildAt(1);
            view.setTypeface(mTypeface, Typeface.NORMAL);
        }
    }
}

所有功劳都归功于Andreyua的原始代码片段,并进行了少量修改.

不幸的是,我没有足够的声誉来发表评论,或者我会直接回复:)

试试这个CustomTabLayout

public class CustomTabLayout extends TabLayout {
    public CustomTabLayout(Context context) {
        super(context);
    }

    public CustomTabLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CustomTabLayout(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    public void setTabsFromPagerAdapter(@NonNull PagerAdapter adapter) {
            Typeface typeface = Typeface.createFromAsset(getContext().getAssets(), "fonts/Roboto-Medium.ttf");

        this.removeAllTabs();

        ViewGroup slidingTabStrip = (ViewGroup) getChildAt(0);

        for (int i = 0, count = adapter.getCount(); i < count; i++) {
            Tab tab = this.newTab();
            this.addTab(tab.setText(adapter.getPageTitle(i)));
            AppCompatTextView view = (AppCompatTextView) ((ViewGroup)slidingTabStrip.getChildAt(i)).getChildAt(1);
            view.setTypeface(typeface, Typeface.NORMAL);
        }
    }
}

使用 android 支持库 26.2.0，您可以在样式中指定字体

<style name="TabLayout" parent="Widget.Design.TabLayout">
    <item name="tabTextAppearance">@style/TabText</item>
    <item name="tabSelectedTextColor">@color/white</item>
    <item name="tabIndicatorColor">@color/white</item>

</style>

<style name="TabText" parent="TextAppearance.Design.Tab">
    <item name="android:textSize">14sp</item>
    <item name="android:textColor">@color/lite</item>
    <!--Here below-->
    <item name="android:fontFamily">@font/gotham_medium</item>
</style>
