设置字体为警告对话框项自定义字体

问题描述：

我创造一个警告对话框是这样的：

I'm creating an alert dialog this way:

AlertDialog.Builder alertDialog = new AlertDialog.Builder(view.getContext());
alertDialog.setCustomTitle(null);
alertDialog.setItems(getAllListNames(), new DialogInterface.OnClickListener() {
  @Override
  public void onClick(DialogInterface dialogInterface, int i) {
      //Doing something awesome...
  }
});

我知道它会创建一个列表视图与我的项目，我想设置为他们的自定义字体的字体，还为每个列表项字符的最大数量，我该怎么办呢？

I know it creates a list view with my items, I want to set a typeface with a custom font for them and also set a max number of characters for each list item, how can I do it?

答

您必须创建一个自定义主题。下面是官方指南： http://developer.android.com/guide/topics /ui/themes.html :)

You have to create a custom theme. Here is the official guide: http://developer.android.com/guide/topics/ui/themes.html :)

像这样的东西（在 style.xml 文件）：

Something like this (in the style.xml file):

<style name="CustomFontTheme" parent="android:Theme.Light">
    <item name="android:textViewStyle">@style/MyTextViewStyle</item>
    <item name="android:buttonStyle">@style/MyButtonStyle</item>
</style>

<style name="MyTextViewStyle" parent="android:Widget.TextView">
    <item name="android:fontFamily">sans-serif-light</item>
</style>

<style name="MyButtonStyle" parent="android:Widget.Holo.Button">
    <item name="android:fontFamily">sans-serif-light</item>
</style>

然后当你创建对话框，你可以这样做：

Then when you create the dialog you can do this:

Context context = new ContextThemeWrapper(view.getContext(), R.style.CustomFontTheme)
AlertDialog.Builder alertDialog = new AlertDialog.Builder(context);

其中， R.style.CustomFontTheme 是他们已经创建的ID。

Where R.style.CustomFontTheme is the id for the them you have created.

更新：

好吧，来添加自定义的字体，你可以按照这个要点是：

Ok, to add your custom typeface you can follow this gist: https://gist.github.com/artem-zinnatullin/7749076

关键是要覆盖一个给定的字型应用程序启动时是这样的：

The key is to override the a given font face when the application starts like this:

TypefaceUtil.overrideFont(getApplicationContext(), "AWESOME-FONT", "fonts/Awesome-Font.ttf");

要点有该方法的实现。

the gist has the implementation for that method.

所以，主题样式看起来应该是现在这个样子：

So the theme styles should look like this now:

<style name="MyTextViewStyle" parent="android:Widget.TextView">
    <item name="android:fontFamily">awesome-font</item>
</style>

<style name="MyButtonStyle" parent="android:Widget.Holo.Button">
    <item name="android:fontFamily">awesome-font</item>
</style>
