标签： java android textview typeface

我尝试使用TypeFace类在TextView上实现自定义字体，如下所示：

package com.royal.bikers;

import android.app.Activity;
import android.os.Bundle;

public class AboutUs extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.about);

        TextView aboutUs1 = (TextView) findViewById(R.id.aboutUs1);
        TextView aboutUs2 = (TextView) findViewById(R.id.aboutUs2);
        TextView aboutUs3 = (TextView) findViewById(R.id.aboutUs3);
        TextView aboutUs4 = (TextView) findViewById(R.id.aboutUs4);
        TextView aboutUs5 = (TextView) findViewById(R.id.aboutUs5);
        TextView aboutUsTitle = (TextView) findViewById(R.id.aboutUsTitle);

        Typeface tf = Typeface.createFromAsset(getAssets(), "fonts/Roboto-Thin.ttf");

        aboutUs1.setTypeface(tf);
        aboutUs2.setTypeface(tf);
        aboutUs3.setTypeface(tf);
        aboutUs4.setTypeface(tf);
        aboutUs5.setTypeface(tf);
        aboutUsTitle.setTypeface(tf);
    }

}

但应用程序崩溃了：

我曾尝试使用另一种名为 Usuzi 的字体，但它运行良好，但我想将其更改为 Roboto-Thin ，而且它不是＆＃39;与...合作。

这是我的 AboutUs.xml ：

除了创建自定义TextTextView类以及 here

的TextView扩展TextView之外，请建议我是否有任何其他方法

好的，然后尝试这个，可能是它的流问题

public class Typefaces {
private static final String TAG = "Typefaces";

private static final Hashtable<String, Typeface> cache = new Hashtable<String, Typeface>();

public static Typeface get(Context c, String assetPath) {
    synchronized (cache) {
        if (!cache.containsKey(assetPath)) {
            try {
                Typeface t = Typeface.createFromAsset(c.getAssets(),
                        assetPath);
                cache.put(assetPath, t);
            } catch (Exception e) {
                Log.e(TAG, "Could not get typeface '" + assetPath
                        + "' because " + e.getMessage());
                return null;
            }
        }
        return cache.get(assetPath);
    }
}

}

这里的答案就是删除字体字符串并仅使用字体名称。

Typeface tf = Typeface.createFromAsset(getAssets(),"Roboto-Thin.ttf");

答案 2 :(得分：0)

制作自定义字体装载程序

public class FontLoader {
private static Typeface quickSandTypeface = null;
private static Typeface quickSandTypefaceBold = null;

public static void loadFonts(Context context) {
    quickSandTypeface = Typeface.createFromAsset(context.getAssets(), "quicksand_regular.ttf");
    quickSandTypefaceBold = Typeface.createFromAsset(context.getAssets(), "quicksand_bold.ttf");
}

public static Typeface getQuickSandTypeface() {
    return quickSandTypeface;
}

public static Typeface getQuickSandTypefaceBold() {
    return quickSandTypefaceBold;
}

public static void setQuickSandTypeface(EditText... editTextViews) {
    if (null != editTextViews && null != quickSandTypeface) {
        for (int i = 0; i < editTextViews.length; i++) {
            editTextViews[i].setTypeface(getQuickSandTypeface());
        }
    }

}

以这种方式在您的活动中使用

FontLoader.setQuickSandTypeface（yourEditText）

答案 3 :(得分：-1)

试试这个它会帮助你。

        Typeface font = Typeface.createFromAsset(getApplicationContext().getAssets(),"fonts/helvetica.ttf");

ttf文件应该是小写字母。
