SpannableStringBuilder setSpan 不适用于阿拉伯语文本 [英] SpannableStringBuilder setSpan doesn't work on Arabic text
问题描述
我正在尝试构建一个包含不同颜色空间字符的阿拉伯字符串，文本应为黑色，特殊字符为红色，句子之间的大小不同.像这样:
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"/>
这是我的代码:
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，但仍然无法使 " (#) " 变红变小:
I have tried solutions for following question but still can't make " (#) " red and small:
SpannableStringBuilder 创建具有多种字体的字符串/文本大小等示例?
有人可以帮我吗?
更新:
这些都不会使文本变红:
None of these make text red:
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);
这也不起作用:
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);
已解决:
我已经解决了.问题出在 PixUI 库，我用来加载我的自定义阿拉伯字体.当我删除它 setSpan 工作.我已经切换到 Calligraphy 库来加载我的自定义字体.
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.
以下代码和布局工作正常:
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 你说得对颜色代码.它应该是 0xAARRGGBB 的形式
@pskink you were right about color code. It should be in form of 0xAARRGGBB
推荐答案
使用 Calligraphy 而不是 PixUI.这是它的 Gradle 依赖:
Use Calligraphy instead of PixUI. Here is the Gradle dependecy for it:
compile 'uk.co.chrisjenx:calligraphy:2.1.0'
使用 TextView 而不是像 PixUI TextView 那样的自定义 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"/>
在构建结果文本后应用自定义字体:
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);
为 ForegroundColorSpan 使用颜色代码，例如 0xAARRGGBB 就像 @pskink 建议的那样:
Use color code for ForegroundColorSpan like 0xAARRGGBB as @pskink suggested:
ssb.setSpan(new ForegroundColorSpan(0xFFFF0000), start, ssb.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
