如何设置字体选项菜单？ [英] How to set a font for the Options menu?

问题描述

当我创建一个选项菜单中的项目似乎默认为本地的SANS字体。当我看到商业应用程序，他们似乎主要是为了做同样的事情。是否可以设置字体大小，颜色的重量或字样的选项菜单项？

When I create an Options Menu the items seem to default to the native "sans" font. When I look at commercial apps they mostly seem to do the same thing. Is it possible to set the font size, color weight or typeface for Option Menu items?

在此先感谢。

推荐答案

您可以自定义选项菜单，其中包括：

You can customize the option menu, including:

1. 添加自定义字体

1. Add a custom font

改变字体大小

更​​改字体颜色

设置背景为绘制资源（如图像，边境，梯度）

Set background to a Drawable resource (e.g. image, border, gradient)

要更改背景边框或渐变，你必须创建在 RES 名为绘制和资源文件夹，里面，创建边框XML或渐变XML。

To change background to a border or gradient you have to create a resource folder in res called drawable and, inside it, create the border XML or gradient XML.

这都是可以做的编程方式，如下所示：

This can all be done programatically as shown below:

public class CustomMenu extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    public boolean onCreateOptionsMenu(android.view.Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.cool_menu, menu);
        getLayoutInflater().setFactory(new Factory() {
            public View onCreateView(String name, Context context,
                    AttributeSet attrs) {

                if (name.equalsIgnoreCase(
                        "com.android.internal.view.menu.IconMenuItemView")) {
                    try {
                        LayoutInflater li = LayoutInflater.from(context);
                        final View view = li.createView(name, null, attrs);
                        new Handler().post(new Runnable() {
                            public void run() {
                                // set the background drawable if you want that
                                //or keep it default -- either an image, border
                                //gradient, drawable, etc.
                                view.setBackgroundResource(R.drawable.myimage);
                                ((TextView) view).setTextSize(20); 

                                // set the text color
                                Typeface face = Typeface.createFromAsset(
                                        getAssets(),"OldeEnglish.ttf");     
                                ((TextView) view).setTypeface(face);
                                ((TextView) view).setTextColor(Color.RED);
                            }
                        });
                        return view;
                    } catch (InflateException e) {
                        //Handle any inflation exception here
                    } catch (ClassNotFoundException e) {
                        //Handle any ClassNotFoundException here
                    }
                }
                return null;
            }
        });
        return super.onCreateOptionsMenu(menu);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
        case R.id.AboutUs:
            Intent i = new Intent("com.test.demo.ABOUT");
            startActivity(i);
            break;
        case R.id.preferences:
            Intent p = new Intent("com.test.demo.PREFS");
            startActivity(p);
            break;
        case R.id.exit:
            finish();
            break;
        }
        return false;
    }
}

不要忘了创建一个名为菜单在 RES 文件夹中的文件夹，和菜单里面文件夹中创建一个XML为您的菜单（如 cool_menu.xml ）像这样的：

Dont forget to create folder called menu in res folder, and inside the menu folder create an XML for your menu (e.g. cool_menu.xml) such as this:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item  android:title="about"android:id="@+id/AboutUs" /> 
    <item android:title="Prefs" android:id="@+id/preferences" /> 
    <item android:title="Exit" android:id="@+id/exit" /> 
</menu>

那么输出将是这样的：

Then the output will be something like this:
