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。

我们需要使用反射来实现这一点

final int titleId = activity.getResources().getIdentifier("action_bar_title", "id", "android");

    final TextView title;
    if (activity.findViewById(titleId) != null) {
        title = (TextView) activity.findViewById(titleId);
        title.setTextColor(Color.BLACK);
        title.setTextColor(configs().getColor(ColorKey.GENERAL_TEXT));
        title.setTypeface(configs().getTypeface());
    } else {
        try {
            Field f = bar.getClass().getDeclaredField("mTitleTextView");
            f.setAccessible(true);
            title = (TextView) f.get(bar);
            title.setTextColor(Color.BLACK);
            title.setTypeface(configs().getTypeface());
        } catch (NoSuchFieldException e) {
        } catch (IllegalAccessException e) {
        }
    }

书法库让你通过应用程序主题设置自定义字体,这也适用于操作栏。

<style name="AppTheme" parent="android:Theme.Holo.Light.DarkActionBar">
<item name="android:textViewStyle">@style/AppTheme.Widget.TextView</item>
</style>

<style name="AppTheme.Widget"/>

<style name="AppTheme.Widget.TextView" parent="android:Widget.Holo.Light.TextView">
   <item name="fontPath">fonts/Roboto-ThinItalic.ttf</item>
</style>

激活书法所需要的是将它附加到你的活动上下文:

@Override
protected void attachBaseContext(Context newBase) {
    super.attachBaseContext(new CalligraphyContextWrapper(newBase));
}

默认的自定义属性是fontPath,但是您可以通过在Application类中使用calligraphy hyconfig . builder初始化它来为路径提供您自己的自定义属性。不鼓励使用android:fontFamily。

int titleId = getResources().getIdentifier("action_bar_title", "id",
            "android");
    TextView yourTextView = (TextView) findViewById(titleId);
    yourTextView.setTextColor(getResources().getColor(R.color.black));
    yourTextView.setTypeface(face);

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

public void findAndSetFont(){
        getActionBar().setTitle("SOME TEST TEXT");
        scanForTextViewWithText(this,"SOME TEST TEXT",new SearchTextViewInterface(){

            @Override
            public void found(TextView title) {

            } 
        });
    }

public static void scanForTextViewWithText(Activity activity,String searchText, SearchTextViewInterface searchTextViewInterface){
    if(activity == null|| searchText == null || searchTextViewInterface == null)
        return;
    View view = activity.findViewById(android.R.id.content).getRootView();
    searchForTextViewWithTitle(view, searchText, searchTextViewInterface);
}

private static void searchForTextViewWithTitle(View view, String searchText, SearchTextViewInterface searchTextViewInterface)
{
    if (view instanceof ViewGroup)
    {
        ViewGroup g = (ViewGroup) view;
        int count = g.getChildCount();
        for (int i = 0; i < count; i++)
            searchForTextViewWithTitle(g.getChildAt(i), searchText, searchTextViewInterface);
    }
    else if (view instanceof TextView)
    {
        TextView textView = (TextView) view;
        if(textView.getText().toString().equals(searchText))
            if(searchTextViewInterface!=null)
                searchTextViewInterface.found(textView);
    }
}
public interface SearchTextViewInterface {
    void found(TextView title);
}
