在活动的所有textViews设置字体？ [英] Set font for all textViews in activity?

问题描述

是否有可能设置字体为一个活动的所有TextViews？我可以通过设置字体为一个TextView的：

Is it possible to set the font for all the TextViews in a activity? I can set the font for a single textView by using:

    TextView tv=(TextView)findViewById(R.id.textView1); 
    Typeface face=Typeface.createFromAsset(getAssets(), "font.ttf"); 
    tv.setTypeface(face);

不过，我想改变，而不是手动设置它为每一个TextView的所有textViews一次，所有信息将是AP preciated！

But I would like to change all the textViews at once, instead of setting it manually for every textView, any info would be appreciated!

推荐答案

解决方法1 ::通过传递父视图作为参数，只需调用这些方法。

Solution1:: Just call these method by passing parent view as argument.

private 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(Typeface.createFromAsset(context.getAssets(), "font.ttf"));
        }
    } catch (Exception e) {
 }
 }

溶液2 ::你也可以继承的TextView的类与您的自定义字体和使用，而不是TextView的吧。

Solution2:: you can subclass the TextView class with your custom font and use it instead of textview.

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();
    }

    private void init() {
        if (!isInEditMode()) {
            Typeface tf = Typeface.createFromAsset(getContext().getAssets(), "font.ttf");
            setTypeface(tf);
        }
    }

}
