在Kotlin中,如果你想使用字节流将字符串写入文件或从文件读取字符串,你可以结合OutputStreamWriter与InputStreamReader以及缓冲区来优雅地实现。 importjava.io.*funwriteStringToFileUsingJavaIo(filePath:String,content:String,charset:Charset=Charsets.UTF_8){valfile=File(filePath)valoutputStream:OutputStream=FileO...
val file = File(appContext.filesDir, pathname) createParentDirectory(file) file.writeText(text) } /** * 写文本(追加)。内部存储空间目录(沙盒)的 files 目录下。 */ fun append(pathname: String, text: String) { if (pathname.isEmpty()) { Log.e("sgx", "pathname 不可为空字符串") return...
write(b, off, len) } } rangeDownloadAndSaveToFile(url, range.first, range.last, obj, { // 下载成功 if (lock.tryLock()) { accessFile.seek(it.first) writeToAccessFile(buffer, accessFile) synchronized(accessFile) { accessFile.notifyAll() } writeCount.getAndAdd(it.last - it.first) ...

writeText("") 可以通过file对象直接将数据写入到文件中。 以readText为例子: public fun File.readText(charset: Charset = Charsets.UTF_8): String = readBytes().toString(charset) // 创建一个FileInputSream 并将数据读取出来 public fun File.readBytes(): ByteArray = FileInputStream(this).use {...
