自定义字体和自定义的TextView在Android [英] Custom Fonts and Custom Textview on Android

问题描述

这是我需要开发一个应用程序，我已经收到了许多文件，如字体名正规特定的字体， FONTNAME粗体， FONTNAME-它的。我需要使用它在应用程序的所有textviews。首先，我认为这是一件容易的事。查看SO，发现了一个非常漂亮的主题：<一href="http://stackoverflow.com/questions/6926263/add-custom-font-for-complete-android-application">here

From an application I need to develop, I've received a specific font that has many files like FontName-Regular, FontName-Bold, FontName-it. I need to use it in all the textviews in the application. First I thought it was an easy task. Look over SO and found a very nice thread:here

所以首先我不喜欢：

public static void overrideFonts(final Context context, final View v) {
    try {
        if (v instanceof ViewGroup) {
            ViewGroup vg = (ViewGroup) v;
            for (int i = 0; i < vg.getChildCount(); i++) {
                View child = vg.getChildAt(i);
                overrideFonts(context, child);
            }
        } else if (v instanceof TextView) {
            ((TextView)v).setTypeface(FONT_REGULAR);
        }
    } catch (Exception e) {
        e.printStackTrace();
        // ignore
    }
}

和所谓的onCreate在此方法在我的活动。在我的应用程序的每个TextView的是显示出的字体和孩子，是我快乐的越来越远那么容易。直到我到了一个屏幕，在这里需要一些textviews 粗体作为风格（安卓TEXTSTYLE =黑体）。然后，我意识到，这个解决方案没有为我提供可能加载的字体粗体从资产.TTF。

And called this method during onCreate in my activity. Every textView in my app was showing that font and boy, was I happy for getting away so easy. Until I got to a screen where some textviews required Bold as Style (android:textStyle="bold"). Then I realized that this solution does not provide me with possibility to load the Font-Bold.ttf from assets.

看起来比进一步看到了一个漂亮的自定义TextView的实施，在相同的SO问题：

Than looked further and saw a nice custom TextView implementation, in the same SO question:

public class MyTextView extends TextView {

    public MyTextView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        init();
    }

    public MyTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
        init();
    }

    public MyTextView(Context context) {
        super(context);
        init();
    }

    public void init() {

        Typeface tf = Typeface.createFromAsset(getContext().getAssets(), "font/chiller.ttf");
        setTypeface(tf ,1);

    }
    }

这看起来更好。我的问题是：我怎么可以检测的init（）如果我的控制已经样式设置为粗体或不那么我可以指定所需的字体

This looks even better. My question is: how can I detect on init() if my control has Style set to Bold or not so I can assign the requested TypeFace ?

感谢您的时间。

LE。按照下面的例子中，我已经更新了我的类：

LE. Following the example below, I've updated my class as:

public class MyTextView extends TextView {

    Typeface normalTypeface = Typeface.createFromAsset(getContext().getAssets(), Constants.FONT_REGULAR);
    Typeface boldTypeface = Typeface.createFromAsset(getContext().getAssets(),  Constants.FONT_BOLD);

    public MyTextView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    public MyTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public MyTextView(Context context) {
        super(context);
    }

    public void setTypeface(Typeface tf, int style) {
        if (style == Typeface.BOLD) {
            super.setTypeface(boldTypeface/*, -1*/);
        } else {
            super.setTypeface(normalTypeface/*, -1*/);
        }
    }
}

那么如果我调试，应用程序进去setTypeFace，似乎运用大胆的，但在我的布局我看不到任何改变，而不是大胆。不管我用什么字体，没有更改完成我的TextView并显示与默认的Andr​​oid字体。我不知道为什么？

Well If I debug, the app goes in setTypeFace and it seems to apply the bold one, but on my layout I can't see any change, not bold. No matter what font I use, no changes are done in my TextView and is displayed with the default android font. I wonder why ?

我总结的一切在一篇博客文章<一个href="http://alinberce.word$p$pss.com/2012/01/25/using-custom-fonts-in-android-bold-italic-regular-you-name-it/">here在我的博客也许这将帮助别人。

I have summed everything on a blog post here on my blog maybe it will help someone.

推荐答案

的的TextView 调用构造 setTypeface（字体TF，INT风格）与风格从XML属性检索参数安卓TEXTSTYLE 。所以，如果你想截获此调用逼你自己的字体，你可以重写此方法如下：

The constructor of TextView calls setTypeface(Typeface tf, int style) with the style parameter retrieved from the XML attribute android:textStyle. So, if you want to intercept this call to force your own typeface you can override this method as follow:

public void setTypeface(Typeface tf, int style) {
    Typeface normalTypeface = Typeface.createFromAsset(getContext().getAssets(), "font/your_normal_font.ttf");
    Typeface boldTypeface = Typeface.createFromAsset(getContext().getAssets(), "font/your_bold_font.ttf");

    if (style == Typeface.BOLD) {
        super.setTypeface(boldTypeface/*, -1*/);
    } else {
        super.setTypeface(normalTypeface/*, -1*/);
    }
}
