我工作的应用程序转换为不支持的语言 - 缺少设备字体。 因此，我增加字体的应用，改变字体为所有TextViews，EditTexts，按钮。 此外，我能够改变字体中的WebView。 但现在我需要改变字体的所有系统组件：
动作条：
对话
有没有办法来改变字体为这个组件。 大概都在他们一些的TextView - 只知道自己的身份证去找他们。
请不要张贴关于TextView的改变字样的答案！

添加内部资产/字体的字体
Arial-Bold.ttf
Arial-BoldItalic.ttf
Arial-Italic.ttf
Arial-Regular.ttf
创建自定义视图例如 ：FontableTextView.java
import android.content.Context;
import android.content.res.TypedArray;
import android.graphics.Canvas;
import android.util.AttributeSet;
import android.widget.TextView;
public class FontableTextView extends TextView
{
private static final String TAG = "FontableTextView";
public FontableTextView(Context context)
{
super(context);
}
public FontableTextView(Context context, AttributeSet attrs)
{
super(context, attrs);
setCustomFont(context, attrs);
}
public FontableTextView(Context context, AttributeSet attrs, int defStyle)
{
super(context, attrs, defStyle);
setCustomFont(context, attrs);
}
/*
* @see android.widget.CompoundButton#onDraw(android.graphics.Canvas)
*/
@Override
protected void onDraw(Canvas canvas)
{
super.onDraw(canvas);
}
private void setCustomFont(Context ctx, AttributeSet attrs)
{
// Fonts work as a combination of particular family and the style.
TypedArray a = ctx.obtainStyledAttributes(attrs, R.styleable.Fonts);
String family = a.getString(R.styleable.Fonts_font);
int style = a.getInt(R.styleable.Fonts_android_textStyle, -1);
a.recycle();
// Set the typeface based on the family and the style combination.
if ( family != null )
{
setTypeface(FontManager.getInstance().get(family, style));
}
}
}
启动FontManager在在MainActivity开始设置自定义字体
FontManager.getInstance().initialize(getApplicationContext(), R.xml.fonts);
在使用XML布局自定义视图
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:custom="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<com.package.FontableTextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="20dip"
android:text="FontableTextView"
android:textStyle="bold"
custom:font="Arial" />
</RelativeLayout>
使用动作条福尔摩斯（ http://actionbarsherlock.com/ ）和自定义它的代码：
在com.actionbarsherlock.app.Actionbar添加这两个抽象方法：
public abstract void setTitleTypeface(Typeface TF);
public abstract void setSubtitleTypeface(Typeface TF);
和覆盖com.actionbarsherlock.internal.app.ActionBarImpl这些方法
@Override
public void setTitleTypeface(Typeface TF) {
mActionView.setTitleTypeface(TF); }
@Override
public void setSubtitleTypeface(Typeface TF) {
mActionView.setSubtitleTypeface(TF); }
而且在com.actionbarsherlock.internal.app.ActionBarWrapper这样
@Override
public void setTitleTypeface(Typeface TF) {}
@Override
public void setSubtitleTypeface(Typeface TF) {}
终于在com.actionbarsherlock.internal.widget.ActionBarView添加这些方法：
public void setTitleTypeface(Typeface TF){
mTitleView.setTypeface(TF);
}
public void setSubtitleTypeface(Typeface TF){
mSubtitleView.setTypeface(TF);
}
现在在你的SherlockActivity像这样使用它：
Typeface TF = Typeface.createFromAsset(getApplication().getAssets(),
"Arial.ttf");
getSupportActionBar().setTitleTypeface(TF);
确保有没有更好的办法！
2.对话框，系统设置，...ü应该改变这样的代码！
