坦率地说,标题说明了一切,我正在尝试更改输入法服务,键盘视图键盘字体。当然......它不像
那么简单 android:keyTextFont="sans-serif"
。

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();
}
}
}
将此类添加到您的代码中。
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");*/
}
}
.....在这里你可以看到添加了一些fonts / fontname。这些是外部字体文件,您可以使用它们覆盖键盘视图/标签。
将此应用程序名称添加到android清单文件应用程序名称
中例如
<application
android:name=".Application"
android:allowBackup="false"
android:installLocation="internalOnly"
android:label="@string/ime_name"
android:theme="@style/AppTheme" >.......
现在将上面覆盖的字体名称更新为您的样式。基本主题或您在清单应用程序中使用的主题。
例如
<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
<item name="android:typeface">monospace</item>
</style>

是的,可以通过重写KeyboardView的onDraw()方法来实现。
以下是有人在键上方添加文字的示例:Customize the appearance of a <Key>
更改文本字体代码将是这样的:
public class MyKeyboardView extends KeyboardView {
@Override
public void onDraw(Canvas canvas) {
Paint paint = new Paint();
paint.setTextAlign(Paint.Align.CENTER);
Typeface font = Typeface.createFromAsset(context.getAssets(),
"fonts/Hippie.otf"); //Insert your font here.
paint.setTypeface(font);
List<Key> keys = getKeyboard().getKeys();
for(Key key: keys) {
if(key.label != null)
canvas.drawText(key.label.toString(), key.x, key.y, paint);
}
}
}

您必须创建一个扩展KeyboardView的新类。
package com.example.xyz;
...
...
public class CustomKeyboardView extends KeyboardView{
@Override
public void onDraw(Canvas canvas) {
Paint mPaint = new Paint();
mPaint.setTextAlign(Paint.Align.CENTER);
mPaint.setTextSize(40);
mPaint.setColor(Color.BLACK);
Typeface font = Typeface.createFromAsset(mContext.getAssets(),"normal_font.ttf");
mPaint.setTypeface(font);
if (key.label != null) {
String keyLabel = key.label.toString();
if (caps) {
keyLabel = keyLabel.toUpperCase();
}
canvas.drawText(keyLabel, key.x + (key.width / 2),
key.y + (key.height / 2) , mPaint);
} else if (key.icon != null) {
key.icon.setBounds(key.x, key.y, key.x + key.width, key.y + key.height);
key.icon.draw(canvas);
}
}
}
.ttf
文件是项目Assets
文件夹中的字体文件。
现在,在键盘布局(.xml)文件中,将<KeyboardView/>
替换为<com.example.xyz.CustomKeyboardView/>
