＆QUOT;本地字体不能作出＆QUOT;只对某些人 [英] "Native typeface cannot be made" only for some people

问题描述

我有一个应用程序，更改字体字样的某些元素。它适用于大多数人，但也许尝试更改字体时，0.5％，得到一个异常。堆栈跟踪的显著的部分是这样的：

 产生的原因：java.lang.RuntimeException的：本地字体不可言
在android.graphics.Typeface＆LT; INIT＆GT;（Typeface.java:147）
在android.graphics.Typeface.createFromAsset（Typeface.java:121）
 

正如我说的，它适用于大多数人，所以我不认为这是与字体文件或我的code的一个问题。关于如何解决这个任何建议？

编辑：这是我的code：

 字样phoneticFont = Typeface.createFromAsset（getAssets（）
                                                 字体/ CharisSILR.ttf）;
TextView的电视;
电视=（（TextView中）findViewById（R.id.searchPronunciationTitle））;
tv.setTypeface（phoneticFont）;
 

解决方案

Android操作系统的这种错误可能是你的问题的原因：

Typeface.createFromAsset泄漏资产流

还都在这个错误报告要解决此问题其中：

  

我改变了心连心的解决方法，使该方法不承担字体   路径或格式。字体资产的完整路径必须提交   的参数。我还裹着调用createFromAsset（）在   try-catch块，这样的get（）方法，如果资产返回null   未找到。

 公共类字样{
    私有静态最后字符串变量=字样;

    私有静态最后的Hashtable＆LT;字符串，字体＆GT;缓存=新的Hashtable＆LT;字符串，字体＆GT;（）;

    公共静态字样的get（上下文C，串assetPath）{
        同步（缓存）{
            如果（！cache.containsKey（assetPath））{
                尝试 {
                    字样T = Typeface.createFromAsset（c.getAssets（）
                            assetPath）;
                    cache.put（assetPath，T）;
                }赶上（例外五）{
                    Log.e（TAG，无法获取字体'+ assetPath
                            +，因为+ e.getMessage（））;
                    返回null;
                }
            }
            返回cache.get（assetPath）;
        }
    }
}
 

I have an app that changes the font typeface for some elements. It works well for most of the people, but maybe a 0.5% get an exception when trying to change the font. The significant part of the stack trace is this:

Caused by: java.lang.RuntimeException: native typeface cannot be made
at android.graphics.Typeface.<init>(Typeface.java:147)
at android.graphics.Typeface.createFromAsset(Typeface.java:121)

As I say, it works for most of the people, so I don't think it is a problem with the font file or my code. Any suggestions about how to solve this?

Edit: This is my code:

Typeface phoneticFont = Typeface.createFromAsset(getAssets(),
                                                 "fonts/CharisSILR.ttf");
TextView tv;
tv = ((TextView) findViewById(R.id.searchPronunciationTitle));
tv.setTypeface(phoneticFont);

解决方案

This bug of Android OS could be the reason of your issue:

Typeface.createFromAsset leaks asset stream

Where are also a workaround in this bugreport:

I altered HTH's workaround so that the method does not assume the font path or format. The full path of the font asset must be submitted as a parameter. I also wrapped the call to createFromAsset() in a try-catch block so that the get() method will return null if the asset is not found.

public class Typefaces {
    private static final String TAG = "Typefaces";

    private static final Hashtable<String, Typeface> cache = new Hashtable<String, Typeface>();

    public static Typeface get(Context c, String assetPath) {
        synchronized (cache) {
            if (!cache.containsKey(assetPath)) {
                try {
                    Typeface t = Typeface.createFromAsset(c.getAssets(),
                            assetPath);
                    cache.put(assetPath, t);
                } catch (Exception e) {
                    Log.e(TAG, "Could not get typeface '" + assetPath
                            + "' because " + e.getMessage());
                    return null;
                }
            }
            return cache.get(assetPath);
        }
    }
}
