通过资产字体更改PreferenceFragment字体 [英] Change PreferenceFragment font via asset fonts

问题描述

为了在PreferenceFragment中为每个首选项设置自定义字体，我必须为每个首选项类型( CustomSwitchPreference ， CustomEditTextPreference ， CustomListPreference ，....)，并在 onBindView 方法中设置其字体.

In order to have custom fonts for each Preference in PreferenceFragment, I had to write a new customized class for each preference type (CustomSwitchPreference, CustomEditTextPreference, CustomListPreference ,....) and set its font in onBindView method.

它有效，但这是最好的解决方案吗?没有矮个子了吗?

It works, but is this best solution? No shorter one?

@Override
public void onBindView(View view){
    super.onBindView(view);
    TextView title = (TextView) view.findViewById(android.R.id.title);
    TextView summary = (TextView) view.findViewById(android.R.id.summary);
    Utils.setFont(context, title, customfont);
    Utils.setFont(context, summary, customfont);
}

public class Utils{
    public static boolean setFont(Context context, TextView tv, String fontAssetName) {
        Typeface font = Typeface.createFromAsset(context.getResources().getAssets(), fontAssetName);
        if (font != null) {
            tv.setTypeface(font);
            return true;
        }
        return false;
    }
}

是否可以更改 PreferenceFragment 的所有段(包括对话框)的字体?

Is there any way to change the font for all segments of PreferenceFragment including dialogs?

推荐答案

在您的styles.xml中，添加以下样式:

In your styles.xml, add the following style:

<style name="PreferenceTheme" parent="@style/AppTheme">
    <item name="android:fontFamily">@font/lato</item>
    <item name="fontFamily">@font/lato</item>
</style>

然后，在SettingsFragment.java中，覆盖onCreateView():

Then, in SettingsFragment.java, override the onCreateView():

@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    View view = super.onCreateView(inflater, container, savedInstanceState);
    container.getContext().setTheme(R.style.PreferenceTheme);
    return view;
}

通常可以解决问题.如果没有，请将样式添加到AndroidManifest.xml:

This usually does the trick. If not, add the style to AndroidManifest.xml:

<application
    ...>
    <activity.../>
    <activity
        android:name=".SettingsActivity"
        android:theme="R.style.PreferenceTheme"/>
    ...
</application>

我得到了一个整洁的结果:使用自定义字体的首选项-"Lato"

I'm getting a neat result: Preferences with custom font - "Lato"
