SpannableStringBuilder setSpan不会对阿拉伯文字工作 [英] SpannableStringBuilder setSpan doesn't work on Arabic text

问题描述

我试图构建一个包含空间caracters不同颜色的阿拉伯语字符串，文字应该是句子之间的黑色和特殊catacters红色，不同尺寸。像这样的：

I am trying to build an Arabic string that contains spacial caracters with different color, text should be black and special catacters red, and different size between sentences. Like this:

这是我的TexView定义：

This is my TexView definition:

<com.neopixl.pixlui.components.textview.TextView
    android:id="@+id/sura"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textSize="@dimen/kuran_sure_text_size"
    android:textDirection="rtl"
    pixlui:typeface="fatih_araz_font.ttf"/>

这是我的code：

And this is my code:

SpannableStringBuilder ssb = new SpannableStringBuilder();

for (int i = 0;  i < contentJsonArray.length(); ++i) {
    JSONObject suraJson = (JSONObject)contentJsonArray.get(i);
    Log.d(LOG_TAG, "QuranPageFragment - WebServiceClient.getVerse - success - " +
            "Content " + i + " = " + suraJson.toString());
    ssb.append(suraJson.getString(KEY_VERSE));
    int start = ssb.length();

    if (i == contentJsonArray.length() - 1)
        break;

    // This has to be red and small but it doesn't
    ssb.append(" (#) ");
    ssb.setSpan(new ForegroundColorSpan(R.color.Red), start, ssb.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
    ssb.setSpan(new AbsoluteSizeSpan(10, true), start, ssb.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
}

Log.d(LOG_TAG, "QuranPageFragment - WebServiceClient.getVerse - success - Sura = " + ssb.toString());
suraTextView.setText(ssb, TextView.BufferType.SPANNABLE);

我已经尝试了以下问题的解决方案，但仍无法让（＃）红色小：

<一个href=\"http://stackoverflow.com/questions/10828182/spannablestringbuilder-to-create-string-with-multiple-fonts-text-sizes-etc-examp\">SpannableStringBuilder创建具有多种字体的字符串/文本大小等例子？

谁能帮我？

更新：

这些都不让文字红：

ssb.setSpan(new ForegroundColorSpan(0xFF0000), start, ssb.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
ssb.setSpan(new ForegroundColorSpan(0xFF0000), start, ssb.length(), 0);
ssb.setSpan(new ForegroundColorSpan(getResources().getColor(R.color.Red)), start, ssb.length(), 0);

这也没有工作：

SpannableStringBuilder ssb = new SpannableStringBuilder();

for (int i = 0;  i < contentJsonArray.length(); ++i) {
    JSONObject suraJson = (JSONObject)contentJsonArray.get(i);
    Log.d(LOG_TAG, "QuranPageFragment - WebServiceClient.getVerse - success - " +
            "Content " + i + " = " + suraJson.toString());
    Spannable spannable = new SpannableString(suraJson.getString(KEY_VERSE) + " (#) ");

    if (i == contentJsonArray.length() - 1)
        break;

    spannable.setSpan(
            new ForegroundColorSpan(
                    getResources().getColor(R.color.Red)),
            spannable.length() - 5,
            spannable.length(),
            Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
    spannable.setSpan(
            new AbsoluteSizeSpan(10, true),
            spannable.length() - 5,
            spannable.length(),
            Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
    ssb.append(spannable);
}

Log.d(LOG_TAG, "QuranPageFragment - WebServiceClient.getVerse - success - Sura = " + ssb.toString());
suraTextView.setText(ssb);

解决：的

SOLVED:

我已经解决了它。问题是与 PixUI 库至极我用装载我的自定义阿拉伯字体。当我删除它setSpan工作。我已经向swiched 书法 库加载我自定义字体。

I have solved it. The problem was with PixUI library wich I used to load my custom Arabic font. When I removed it setSpan worked. I have swiched to Calligraphy library to load my custom font.

继code和布局工作正常：

Following code and layout works fine:

<TextView
    android:id="@+id/sura"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textSize="@dimen/kuran_sure_text_size"
    android:textDirection="rtl"/>

SpannableStringBuilder ssb = new SpannableStringBuilder();

for (int i = 0;  i < contentJsonArray.length(); ++i) {
    JSONObject suraJson = (JSONObject)contentJsonArray.get(i);
    Log.d(LOG_TAG, "QuranPageFragment - WebServiceClient.getVerse - success - " +
            "Content " + i + " = " + suraJson.toString());
    ssb.append(suraJson.getString(KEY_VERSE));

    if (i == contentJsonArray.length() - 1)
        break;

    int start = ssb.length();
    ssb.append(" (#) ");
    ssb.setSpan(new ForegroundColorSpan(R.color.Red), start, ssb.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
    ssb.setSpan(new AbsoluteSizeSpan(10, true), start, ssb.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
}

Log.d(LOG_TAG, "QuranPageFragment - WebServiceClient.getVerse - success - Sura = " + ssb.toString());
CalligraphyTypefaceSpan typefaceSpan =
        new CalligraphyTypefaceSpan(
                TypefaceUtils.load(getActivity().getAssets(),
                        "fonts/fatih_araz_font.ttf"));
ssb.setSpan(typefaceSpan, 0, ssb.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
suraTextView.setText(ssb);

结果：

@pskink你是对的颜色code。它应该在0xAARRGGBB形式

@pskink you were right about color code. It should be in form of 0xAARRGGBB

推荐答案

使用书法而不是 PixUI 。这里是摇篮dependecy吧：

Use Calligraphy instead of PixUI. Here is the Gradle dependecy for it:

compile 'uk.co.chrisjenx:calligraphy:2.1.0'

使用的TextView 不是一些定制的的TextView 如 PixUI的TextView 。

Use TextView not some custom TextView like PixUI TextView.

<TextView
    android:id="@+id/sura"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textSize="@dimen/kuran_sure_text_size"
    android:textDirection="rtl"/>

应用自定义字体建设得到的文本后：

Apply custom font after building resulting text:

SpannableStringBuilder ssb = new SpannableStringBuilder();

for (int i = 0;  i < contentJsonArray.length(); ++i) {
    JSONObject json = (JSONObject)contentJsonArray.get(i);
    ssb.append(json.getString(KEY_SOME_KEY));

    if (i == contentJsonArray.length() - 1)
        break;

    int start = ssb.length();
    ssb.append("( # )");
    ssb.setSpan(new ForegroundColorSpan(R.color.Red), start, ssb.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
    ssb.setSpan(new AbsoluteSizeSpan(10, true), start, ssb.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
}

CalligraphyTypefaceSpan typefaceSpan =
        new CalligraphyTypefaceSpan(
                TypefaceUtils.load(getActivity().getAssets(),
                        "fonts/some_custom_font.ttf"));
ssb.setSpan(typefaceSpan, 0, ssb.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
textView.setText(ssb);

使用颜色code为 ForegroundColorSpan 如 0xAARRGGBB 为@pskink建议：

Use color code for ForegroundColorSpan like 0xAARRGGBB as @pskink suggested:

ssb.setSpan(new ForegroundColorSpan(0xFFFF0000), start, ssb.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
