如何在NavigationView中设置项目的自定义字体？
提问于 2015-06-05 21:54:18
使用新的NavigationView，我们可以通过XML语言中的菜单资源来设置抽屉的项目。
这样，我们就可以为每个项目设置如下内容
<item
android:id="@+id/drawer_my_account"
android:icon="@drawable/ic_my_account"
android:title="@string/drawer_my_account" />但是现在，我想为我抽屉中的每一件物品设置一个自定义字体，但是我找不到一种方法来做到这一点，无论是XML还是Java代码。有办法做到这一点吗？

只需将以下类文件添加到项目中即可。
import android.graphics.Paint;
import android.graphics.Typeface;
import android.text.TextPaint;
import android.text.style.TypefaceSpan;
public class CustomTypefaceSpan extends TypefaceSpan {
private final Typeface newType;
public CustomTypefaceSpan(String family, Typeface type) {
super(family);
newType = type;
}
@Override
public void updateDrawState(TextPaint ds) {
applyCustomTypeFace(ds, newType);
}
@Override
public void updateMeasureState(TextPaint paint) {
applyCustomTypeFace(paint, newType);
}
private static void applyCustomTypeFace(Paint paint, Typeface tf) {
int oldStyle;
Typeface old = paint.getTypeface();
if (old == null) {
oldStyle = 0;
} else {
oldStyle = old.getStyle();
}
int fake = oldStyle & ~tf.getStyle();
if ((fake & Typeface.BOLD) != 0) {
paint.setFakeBoldText(true);
}
if ((fake & Typeface.ITALIC) != 0) {
paint.setTextSkewX(-0.25f);
}
paint.setTypeface(tf);
}
}然后为您的活动创建以下方法
private void applyFontToMenuItem(MenuItem mi) {
Typeface font = Typeface.createFromAsset(getAssets(), "ds_digi_b.TTF");
SpannableString mNewTitle = new SpannableString(mi.getTitle());
mNewTitle.setSpan(new CustomTypefaceSpan("" , font), 0 , mNewTitle.length(), Spannable.SPAN_INCLUSIVE_INCLUSIVE);
mi.setTitle(mNewTitle);
}并从activity中调用它。
navView = (NavigationView) findViewById(R.id.navView);
Menu m = navView.getMenu();
for (int i=0;i<m.size();i++) {
MenuItem mi = m.getItem(i);
//for aapplying a font to subMenu ...
SubMenu subMenu = mi.getSubMenu();
if (subMenu!=null && subMenu.size() >0 ) {
for (int j=0; j <subMenu.size();j++) {
MenuItem subMenuItem = subMenu.getItem(j);
applyFontToMenuItem(subMenuItem);
}
}
//the method we have create in activity
applyFontToMenuItem(mi);
}这是我的输出

这个很适合我
<android.support.design.widget.NavigationView
android:id="@+id/navigation_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#4A4444"
android:clipToPadding="false"
android:paddingBottom="50dp"
app:itemIconTint="@color/white"
app:menu="@menu/drawer_home"
app1:itemTextAppearance="@style/NavigationDrawerStyle" >
</android.support.design.widget.NavigationView>资源->值->样式
<style name="NavigationDrawerStyle">
<item name="android:textSize">18sp</item>
<item name="android:typeface">monospace</item>
</style>//设置自定义字体MainApplication.java
public class MainApplication extends Application {
@Override
public void onCreate() {
super.onCreate();
//set Custom Typeface
FontsOverride.setDefaultFont(this, "MONOSPACE", "OpenSans-Semibold.ttf");
}
}// FontsOverride.java
public final class FontsOverride {
public static void setDefaultFont(Context context,
String staticTypefaceFieldName, String fontAssetName) {
final Typeface regular = Typeface.createFromAsset(context.getAssets(),
fontAssetName);
replaceFont(staticTypefaceFieldName, regular);
}
protected static void replaceFont(String staticTypefaceFieldName,
final Typeface newTypeface) {
try {
final Field staticField = Typeface.class
.getDeclaredField(staticTypefaceFieldName);
staticField.setAccessible(true);
staticField.set(null, newTypeface);
} catch (NoSuchFieldException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
}
}

我用过app:theme
<android.support.design.widget.NavigationView
android:id="@+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="@color/colorMenuBackground"
android:fitsSystemWindows="true"
app:headerLayout="@layout/nav_header_main"
app:menu="@menu/activity_main_drawer"
app:theme="@style/NavigationViewTextAppearance"
/>styles.xml：
<style name="NavigationViewTextAppearance">
<item name="android:ellipsize">end</item>
<item name="android:fontFamily">@font/badscript_regular</item>
