我PreferenceActivity的外观如下:
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);
}
}
}
并且 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>
我有特定的语言,因此在about.xml中的文本应该使用特定的字体。通常我会使用以下代码来设置TextView的字体:
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);
但我应该使用什么来访问添加到首选项屏幕中的 about.xml 文本?
谢谢!
