如何(如果可能的话)我可以设置自定义字体在ActionBar标题文本(只有-不是标签文本)与字体在我的资产文件夹?我不想使用android:logo选项。

从Android支持库v26 + Android Studio 3.0起,这个过程变得简单如轻弹!!
按照以下步骤更改工具栏标题的字体:
Read Downloadable Fonts & select any font from the list (my recommendation) or load a custom font to res > font as per Fonts in XML In res > values > styles, paste the following (use your imagination here!) <style name="TitleBarTextAppearance" parent="android:TextAppearance"> <item name="android:fontFamily">@font/your_desired_font</item> <item name="android:textSize">23sp</item> <item name="android:textStyle">bold</item> <item name="android:textColor">@android:color/white</item> </style> Insert a new line in your Toolbar properties app:titleTextAppearance="@style/TextAppearance.TabsFont" as shown below <android.support.v7.widget.Toolbar android:id="@+id/toolbar" android:layout_width="match_parent" android:layout_height="?attr/actionBarSize" android:background="?attr/colorPrimary" app:titleTextAppearance="@style/TitleBarTextAppearance" app:popupTheme="@style/AppTheme.PopupOverlay"/> Enjoy Custom Actionbar Title font styling!!

如果你想在整个活动中设置所有textview的字体,你可以使用这样的东西:
public static void setTypefaceToAll(Activity activity)
{
View view = activity.findViewById(android.R.id.content).getRootView();
setTypefaceToAll(view);
}
public static void setTypefaceToAll(View view)
{
if (view instanceof ViewGroup)
{
ViewGroup g = (ViewGroup) view;
int count = g.getChildCount();
for (int i = 0; i < count; i++)
setTypefaceToAll(g.getChildAt(i));
}
else if (view instanceof TextView)
{
TextView tv = (TextView) view;
setTypeface(tv);
}
}
public static void setTypeface(TextView tv)
{
TypefaceCache.setFont(tv, TypefaceCache.FONT_KOODAK);
}
TypefaceCache:
import java.util.TreeMap;
import android.graphics.Typeface;
import android.widget.TextView;
public class TypefaceCache {
//Font names from asset:
public static final String FONT_ROBOTO_REGULAR = "fonts/Roboto-Regular.ttf";
public static final String FONT_KOODAK = "fonts/Koodak.ttf";
private static TreeMap<String, Typeface> fontCache = new TreeMap<String, Typeface>();
public static Typeface getFont(String fontName) {
Typeface tf = fontCache.get(fontName);
if(tf == null) {
try {
tf = Typeface.createFromAsset(MyApplication.getAppContext().getAssets(), fontName);
}
catch (Exception e) {
return null;
}
fontCache.put(fontName, tf);
}
return tf;
}
public static void setFont(TextView tv, String fontName)
{
tv.setTypeface(getFont(fontName));
}
}
以下代码将适用于所有版本。我确实在gingerbread设备和JellyBean设备上检查了这一点
private void actionBarIdForAll()
{
int titleId = 0;
if(Build.VERSION.SDK_INT>=Build.VERSION_CODES.HONEYCOMB)
{
titleId = getResources().getIdentifier("action_bar_title", "id", "android");
}
else
{
// This is the id is from your app's generated R class when ActionBarActivity is used for SupportActionBar
titleId = R.id.action_bar_title;
}
if(titleId>0)
{
// Do whatever you want ? It will work for all the versions.
// 1. Customize your fonts
// 2. Infact, customize your whole title TextView
TextView titleView = (TextView)findViewById(titleId);
titleView.setText("RedoApp");
titleView.setTextColor(Color.CYAN);
}
}
为了补充@Sam_D的答案,我必须这样做才能使它工作:
this.setTitle("my title!");
((TextView)v.findViewById(R.id.title)).setText(this.getTitle());
TextView title = ((TextView)v.findViewById(R.id.title));
title.setEllipsize(TextUtils.TruncateAt.MARQUEE);
title.setMarqueeRepeatLimit(1);
// in order to start strolling, it has to be focusable and focused
title.setFocusable(true);
title.setSingleLine(true);
title.setFocusableInTouchMode(true);
title.requestFocus();
这似乎有点过分-两次引用v.f entviewbyid (R.id.title)) -但这是唯一的方法,它会让我这样做。
没有自定义的文本视图是必需的!
首先,在你的java代码中禁用工具栏中的标题: getSupportActionBar () .setDisplayShowTitleEnabled(假);
然后,只需在工具栏内添加一个TextView:
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
app:popupTheme="@style/AppTheme.PopupOverlay">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/app_name"
android:textSize="18sp"
android:fontFamily="@font/roboto" />
</android.support.v7.widget.Toolbar>
试试这个
TextView headerText= new TextView(getApplicationContext());
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(ActionBar.LayoutParams.WRAP_CONTENT, ActionBar.LayoutParams.WRAP_CONTENT);
headerText.setLayoutParams(lp);
headerText.setText("Welcome!");
headerText.setTextSize(20);
headerText.setTextColor(Color.parseColor("#FFFFFF"));
Typeface tf = Typeface.createFromAsset(getAssets(), "fonts/wesfy_regular.ttf");
headerText.setTypeface(tf);
getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
getSupportActionBar().setCustomView(headerText);
