设置自定义字体为preferenceScreen文本自定义、文本、字体、preferenceScreen

我的preferenceActivity是这样的：

 进口android.os.Build;
进口android.os.Bundle;
。进口的Android preference preferenceActivity;
。进口的Android preference preferenceFragment;
进口android.widget.TextView;

公共类设置来延长preferenceActivity {

    @燮pressWarnings（德precation）
    @覆盖
    保护无效的onCreate（包savedInstanceState）
    {
            super.onCreate（savedInstanceState）;

            //setContentView(R.layout.about）;

            字样timesFont = Typeface.createFromAsset（getAssets（），字体/ TIMES.TTF）;

            TextView的about_txt =（TextView中）findViewById（R.id.about_txt）;
            about_txt.setTypeface（timesFont）;
            about_txt.setText（R.string.about_txt）;


            如果（Build.VERSION.SDK_INT＆LT; Build.VERSION_ codeS.HONEYCOMB）
            {
                加preferencesFromResource（R.xml preferences。）;
            } 其他 {
                //显示片断为主要内容。
                getFragmentManager（）的BeginTransaction（）代替（android.R.id.content，
                        新的prefsFragment（））提交（）。
            }
    }

    公共静态类prefsFragment扩展preferenceFragment
    {
            @覆盖
            公共无效的onCreate（包savedInstanceState）{
                super.onCreate（savedInstanceState）;

                //从XML资源负载的preferences
                加preferencesFromResource（R.xml preferences。）;
            }
        }
}

和 preference.xml

 ＆LT; preferenceScreen的xmlns：机器人=http://schemas.android.com/apk/res/android＆GT;

        ＆LT;表preference
            机器人：dialogTitle =@字符串/ size_dialog
            机器人：项=@阵列/ size_list
            机器人：entryValues =@阵列/ entry_size
            机器人：关键=size_list
            机器人：总结=@字符串/ size_summary
            机器人：标题=@字符串/ pref4title
            /＆GT;

    ＆LT; / preferenceCategory＆GT;

    ＆LT; preferenceCategory
        机器人：标题=@字符串/ pref_about
        机器人：布局=@布局/约
        ＆GT;

    ＆LT; / preferenceCategory＆GT;

＆LT; / preferenceScreen＆GT;

@布局/约（about.xml）：

 ＆LT; LinearLayout中的xmlns：机器人=http://schemas.android.com/apk/res/android
         的xmlns：工具=http://schemas.android.com/tools
         机器人：layout_width =match_parent
         机器人：layout_height =match_parent＆GT;

          ＆LT;的TextView
            机器人：ID =@ + ID / about_txt
            机器人：layout_width =WRAP_CONTENT
            机器人：layout_height =WRAP_CONTENT
            机器人：文本=这里一些文本
            /＆GT;

＆LT; / LinearLayout中＆GT;

我有特定的语言，所以在about.xml文字我应该使用特定的字体。定期为TextView的使用：

 字样timesFont = Typeface.createFromAsset（getAssets（），字体/ TIMES.TTF）;

 TextView的about_txt =（TextView中）findViewById（R.id.about_txt）;
 about_txt.setTypeface（timesFont）;
 about_txt.setText（R.string.about_txt）;

但我应该用它来获取文本about.xml这增加了prefernce屏？

在此先感谢！

My PreferenceActivity looks like:

import android.os.Build;
import android.os.Bundle;
import android.preference.PreferenceActivity;
import android.preference.PreferenceFragment;
import android.widget.TextView;

public class Settings extends PreferenceActivity {

    @SuppressWarnings("deprecation")
    @Override
    protected void onCreate(Bundle savedInstanceState) 
    {
            super.onCreate(savedInstanceState);

            //setContentView(R.layout.about);

            Typeface timesFont = Typeface.createFromAsset(getAssets(), "fonts/times.ttf");

            TextView about_txt = (TextView) findViewById(R.id.about_txt);        
            about_txt.setTypeface(timesFont);
            about_txt.setText(R.string.about_txt);


            if (Build.VERSION.SDK_INT<Build.VERSION_CODES.HONEYCOMB)
            {
                addPreferencesFromResource(R.xml.preferences);
            } else {
                // Display the fragment as the main content.
                getFragmentManager().beginTransaction().replace(android.R.id.content,
                        new PrefsFragment()).commit();
            }
    }

    public static class PrefsFragment extends PreferenceFragment 
    {
            @Override
            public void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);

                // Load the preferences from an XML resource
                addPreferencesFromResource(R.xml.preferences);
            }
        }
}

And preference.xml

<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">

        <ListPreference
            android:dialogTitle="@string/size_dialog"
            android:entries="@array/size_list"
            android:entryValues="@array/entry_size"
            android:key="size_list"
            android:summary="@string/size_summary"
            android:title="@string/pref4title"
            />

    </PreferenceCategory>

    <PreferenceCategory
        android:title="@string/pref_about"
        android:layout="@layout/about"
        >

    </PreferenceCategory>

</PreferenceScreen>

@layout/about (about.xml):

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
         xmlns:tools="http://schemas.android.com/tools"
         android:layout_width="match_parent"
         android:layout_height="match_parent"> 

          <TextView
            android:id="@+id/about_txt"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="some text here"   
            />

</LinearLayout>

I have specific language, so for text in about.xml I should use specific font. Regularly for TextView I use:

 Typeface timesFont = Typeface.createFromAsset(getAssets(), "fonts/times.ttf");

 TextView about_txt = (TextView) findViewById(R.id.about_txt);        
 about_txt.setTypeface(timesFont);
 about_txt.setText(R.string.about_txt);

but what I should use to access to text in about.xml which add to prefernce screen ?

Thanks in advance!
