字符串分割函数（根据屏幕的宽度或文本的内容）_android 字符串按照width宽度拆分-优快云博客

本文介绍了一种将长字符串根据字体宽度和换行符分割成字符串数组的方法。通过使用Java的流操作读取资源文件中的字符串，并根据指定的宽度限制进行分割，确保每个分割后的字符串适合特定的显示区域。

private String[] splitLongStringIntoStringArray(String StrURL, Font font,int width) { InputStream is = this.getClass().getResourceAsStream(StrURL); ByteArrayOutputStream baos = new ByteArrayOutputStream(); int ch; try { while ((ch = is.read()) != -1) { baos.write(ch); } } catch (IOException e) { System.out.println("无法读取资源文件"); } String longString = new String(baos.toByteArray()); if (font.stringWidth(longString) <= width) { return new String[] { longString }; } else { int stringLength = longString.length(); char[] chars = longString.toCharArray(); Vector v = new Vector(); int offset = 0, length = 1; while (offset + length < stringLength) { if ((chars[offset+length]!='/n')) { //根据文本的最后一个回车符进行分行 length++; } else { v.addElement(longString.substring(offset, offset + length)); offset = offset + length; length = 1; } } // while (offset + length < stringLength) { //根据屏幕的宽度进行分行 // if (font.charsWidth(chars, offset, length) < width) { // length++; // } else { // v.addElement(longString.substring(offset, offset + length)); // offset = offset + length; // length = 1; // } // } if (offset < stringLength) { v.addElement(longString.substring(offset)); } String[] strings = new String[v.size()]; v.copyInto(strings); return strings; } }
