文本全部大写问题

Question

下午好。

我已经实现了TabLayout，当选项卡标题文本的格式字体不起作用时.ttfviewpager。

我已经完成了样式代码，但我面临着同样的问题。

请参阅我的 XML 代码 ->

<android.support.design.widget.TabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
style="@style/CustomTabLayout"
android:background="#eceff1"
app:tabMode="fixed"
app:tabGravity="fill"/>    

样式代码 ->

<style name="CustomTabLayout" parent="Widget.Design.TabLayout">
<item name="tabIndicatorColor">@color/iconGray</item>
<item name="tabIndicatorHeight">3dp</item>
<item name="tabBackground">?attr/selectableItemBackground</item>
<item name="tabTextAppearance">@style/CustomTabTextAppearance</item>
<item name="tabSelectedTextColor">@color/colorPrimary</item>
</style>
<style name="CustomTabTextAppearance" parent="TextAppearance.Design.Tab">
<item name="android:textSize">@dimen/txt_15</item>
<item name="android:textColor">#a4dbb2</item>
<item name="android:fontFamily">@font/amaranth</item>
<item name="textAllCaps">true</item>
</style>

我已经看到了"可能已经有你答案的问题"，但是 我对这些答案不满意

提前谢谢你...

Answer 1

MyClass.java -

public class MyClass extends Application {
@Override
public void onCreate() {
TypefaceUtil.overrideFont(getApplicationContext(), "SERIF", "fonts/Roboto-Regular.ttf"); // font from assets: "assets/fonts/Roboto-Regular.ttf
}
}

主题.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="MyAppTheme" parent="@android:style/Theme.Holo.Light">
<!-- you should set typeface which you want to override with TypefaceUtil -->
<item name="android:typeface">serif</item>
</style>
</resources>

字体实用.java -

import android.content.Context;
import android.graphics.Typeface;
import android.util.Log;
import java.lang.reflect.Field;
public class TypefaceUtil {
/**
* Using reflection to override default typeface
* NOTICE: DO NOT FORGET TO SET TYPEFACE FOR APP THEME AS DEFAULT TYPEFACE WHICH WILL BE OVERRIDDEN
* @param context to work with assets
* @param defaultFontNameToOverride for example "monospace"
* @param customFontFileNameInAssets file name of the font from assets
*/
public static void overrideFont(Context context, String defaultFontNameToOverride, String customFontFileNameInAssets) {
try {
final Typeface customFontTypeface = Typeface.createFromAsset(context.getAssets(), customFontFileNameInAssets);
final Field defaultFontTypefaceField = Typeface.class.getDeclaredField(defaultFontNameToOverride);
defaultFontTypefaceField.setAccessible(true);
defaultFontTypefaceField.set(null, customFontTypeface);
} catch (Exception e) {
Log.e("Can not set custom font " + customFontFileNameInAssets + " instead of " + defaultFontNameToOverride);
}
}
}
