你能以编程方式更改Android键盘文本字体吗？ [英] Can you change the android keyboard text font programmatically?

问题描述

坦率地说，标题说，这一切真的，我试图改变一个输入法服务，KeyboardView的关键字体。当然，这不是简单的

android：keyTextFont =sans-serif。

解决方案

  import java.lang.reflect.Field; 
导入android.content.Context; 
导入android.graphics.Typeface; 
 
 public final class FontsOverride {
 
 public static void setDefaultFont（Context context，
 String staticTypefaceFieldName，String fontAssetName）{
 final Type Regular = Typeface。 createFromAsset（context.getAssets（），
 fontAssetName）; 
 replaceFont（staticTypefaceFieldName，regular）; 
 
 
 protected static void replaceFont（String staticTypefaceFieldName，$ b $ 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（）; 
 
 
 
 
 
 
将这个类加入你的代码。
 $ b $ pre $  public final class Application扩展android.app.Application {
 @Override 
 public void onCreate ）{
 super.onCreate（）; 
 FontsOverride.setDefaultFont（this，DEFAULT，fonts / GeezEdit.ttf）; 
 FontsOverride.setDefaultFont（this，MONOSPACE，fonts / GeezEdit.ttf）; 
 /*FontsOverride.setDefaultFont（this，MONOSPACE，MyFontAsset2.ttf）; 
 FontsOverride.setDefaultFont（this，SERIF，MyFontAsset3.ttf）; 
 FontsOverride.setDefaultFont（this，SANS_SERIF，MyFontAsset4.ttf）; * / 
} 
} 
  

.....在这里您可以看到添加了一些字体/字体名称。这些是外部字体文件，你可以用它来覆盖到你的键盘视图/标签。



将这个应用程序名称添加到Android清单文件应用程序名称中



$ p

$ $ $ $ $
$ android $ name =。Application
android：allowBackup =false
android：installLocation =internalOnly
android：label =@ string / ime_name
android：theme =@ style / AppTheme > .......


现在将上面的过期字体名称更新到您的样式中。基本主题或您在清单应用程序中使用的主题。

示例

 <！ - 应用程序主题。 - > 
< style name =AppThemeparent =AppBaseTheme> 
< item name =android：typeface> monospace< / item> 
< / style> 
  

To be frank the title says it all really, I'm trying to change an input method service, KeyboardView key font. Of course.. it's not as simple as

android:keyTextFont="sans-serif".

解决方案

import java.lang.reflect.Field; 
import android.content.Context;
import android.graphics.Typeface;

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();
    }
  }
}

add this class to your code.

public final class Application extends android.app.Application {
@Override
public void onCreate() {
    super.onCreate();
    FontsOverride.setDefaultFont(this, "DEFAULT", "fonts/GeezEdit.ttf");
    FontsOverride.setDefaultFont(this, "MONOSPACE", "fonts/GeezEdit.ttf");
    /*FontsOverride.setDefaultFont(this, "MONOSPACE", "MyFontAsset2.ttf");
    FontsOverride.setDefaultFont(this, "SERIF", "MyFontAsset3.ttf");
    FontsOverride.setDefaultFont(this, "SANS_SERIF", "MyFontAsset4.ttf");*/
  }
}

..... here you can see that the some fonts/fontname are added. These are the external font files which you can use to overrite into your keyboard view/labels.

add this Application name into the android manifest file application name

example

 <application
    android:name=".Application"
    android:allowBackup="false"
    android:installLocation="internalOnly"
    android:label="@string/ime_name"
    android:theme="@style/AppTheme" >.......

now update the above overrited font name into your style. base theme or the theme which you are using at your manifest application.

example

 <!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
    <item name="android:typeface">monospace</item>
</style>
