运行时异常：字体找不到我尝试过的每个字体 - Android [英] Runtime Exception: Font not found for every font i've tried - Android

问题描述

我有一个自定义扩展 TextView 我正在使用自定义字体在我的应用程序，但由于某种原因，我不断得到一个运行时异常程序不能找到有问题的字体。

我使用的目录格式是 main>资产>字体> Portrait-Light.ttf

我到处寻找一个解决方案，但他们似乎都围绕着同样的答案。
$ b CustomFontTextView.java ：

 公共类CustomFontTextView扩展TextView {
 $ b $公共CustomFontTextView（上下文上下文）{
 super（context）; 
 applyCustomFont（context）; 
 
 
 public CustomFontTextView（Context context，AttributeSet attrs）{
 super（context，attrs）; 
 applyCustomFont（context）; 
 
 $ b $ public CustomFontTextView（Context context，AttributeSet attrs，int defStyle）{
 super（context，attrs，defStyle）; 
 applyCustomFont（context）; 
 
 
 private void applyCustomFont（Context context）{
 Log.e（It get here，custom font）; 
字体customFont = FontCache.getTypeface（Roboto-Italic.ttf，context）; 
 setTypeface（customFont）; 
 
 
 
 
 
  FontCache.java   $ / p> 
 
 
  class FontCache {
 
 private static HashMap< String，Typeface> fontCache = new HashMap<>（）; 
 
静态字体getTypeface（字体字体，上下文上下文）{
字体typeface = fontCache.get（fontname）; 
 if（typeface == null）{
 try {
 typeface = Typeface.createFromAsset（context.getAssets（），fonts /+ fontname）; 
} catch（Exception e）{
 Log.e（failed，e.getMessage（））; 
} 
 fontCache.put（fontname，typeface）; 
} 
返回字体;

 android：layout_marginTop =10dp
 android：textSize =14sp color / colorPrimary
 android：gravity =center_horizo​​ntal
 android：text =@ string / are_you_over_18_years_old/> 
  
我尝试过使用不同的格式，例如 .otf 和不同的字体，比如 Roboto-Italic.ttf 和dafont.com中另一个名为 Sunset-Clouds.ttf 但仍然收到错误信息，发生了什么事？这应该是工作。我甚至更新了所有插件，例如Gradle，Grade-Wrapper发行版和Android gradle插件以防万一。 
 
 
我也尝试过这样做的单一方法： / p> 
 
 
  AssetManager am = context。 getApplicationContext（）。 getAssets（）; 
 Typeface font = Typeface.createFromAsset（
 am，String.format（Locale.US，fonts /％s，portrait-light.ttf））; 
  
我错过了什么？

好的，所以有一个奇怪的解决方法。显然，当你将资产文件夹直接添加到主要文件夹中时，android studio不喜欢它C>应用程序/ SRC /主。你需要首先将它添加到 app / src / main / res 文件夹中，然后将它移动到 main 文件夹。没有一个线索，为什么它是这样的，但它解决了我的问题。
 
解决方案
我认为真正的问题是，你避难没有配置您的资产文件夹。如果你有，在项目视图中看起来像这样：
 
 
 
   
 
 
或者在Android视图中这样：
 
 
 
  
 
 
 
所以你应该在Studio中简单的添加这个文件夹作为资产文件夹：
点击你的项目结构窗口（或按Alt + 1），然后按Alt + Insert并选择Folder / Assets Folder。然后把你的字体放在那里。

I have a custom extended TextView I am using for custom fonts within my application, but for some reason I keep getting a run-time exception where the program can't find the font in question. 

The format of the directory I'm using is main > assets > fonts > Portrait-Light.ttf



I've looked everywhere for a solution but they all seem to be rounding to the same answers on SO. 

CustomFontTextView.java :
public class CustomFontTextView extends TextView {

    public CustomFontTextView(Context context) {
        super(context);
        applyCustomFont(context);
    }

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

    public CustomFontTextView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        applyCustomFont(context);
    }

    private void applyCustomFont(Context context) {
        Log.e("it gets here", "custom font");
        Typeface customFont = FontCache.getTypeface("Roboto-Italic.ttf", context);
        setTypeface(customFont);
    }
}
FontCache.java
class FontCache {

    private static HashMap<String, Typeface> fontCache = new HashMap<>();

    static Typeface getTypeface(String fontname, Context context) {
        Typeface typeface = fontCache.get(fontname);
        if (typeface == null) {
            try {
                typeface = Typeface.createFromAsset(context.getAssets(), "fonts/" + fontname);
            } catch (Exception e) {
                Log.e("failed", e.getMessage());
            }
            fontCache.put(fontname, typeface);
        }
        return typeface;
    }
}
XML:
 <icn.premierandroid.misc.CustomFontTextView
            android:id="@+id/switch_description"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="10dp"
            android:textSize="14sp"
            android:textColor="@color/colorPrimary"
            android:gravity="center_horizontal"
            android:text="@string/are_you_over_18_years_old"/>
I have tried this with different formats such as .otf and with different fonts such as Roboto-Italic.ttf and another random one from dafont.com called Sunset-Clouds.ttf but still i get the error message, what is going on? this should be working. I've even updated all plugins such as Gradle, Grade-Wrapper distribution and Android gradle plugin just in case.

I have also tried the single way of doing it: 
    AssetManager am = context. getApplicationContext(). getAssets();
    Typeface font = Typeface.createFromAsset(
    am, String.format(Locale.US, "fonts/%s", "portrait-light.ttf"));
Am i missing something?

Update: 

Removal of the catch reveals this stacktrace.

UPDATE 2: 

Okay, so there is a weird work-around for this. Apparently android studio doesn't like it when you add the assets folder straight into the main folder inside app/src/main. You need to add it into the app/src/main/res folder first and then move it to the main folder. Don't have a clue why it's like this but it solved my problem.
解决方案
I think the real problem is that you haven't configured your assets folder. If you had, it would look like this in Project view: 



Or like this in Android view:



So you should simply add this folder as assets folder in Studio:
Click on your project structure window (or press Alt+1), then press Alt + Insert and select Folder/Assets Folder. Then put your fonts there.

Update from OP:
