Question

我使用Process来运行本机二进制文件。这不是问题，我可以正常使用InputStream并通过Scanner解析它。如果我while (scanner.hasNextLine())和System.out.println(scanner.nextLine())内，一切都很好。如果我在System.out.println(scanner.nextLine())内运行runOnUiThread()，那么它会混淆我的输出，我不会得到所有内容，但我得到的是同一行的20倍（每次运行的数字不一样）。

在这里，我的完整代码：

processScanner = new Scanner(process.getInputStream());
while(processScanner.hasNextLine()) {
  line = processScanner.nextLine();
  System.out.println(line);
  runOnUiThread(new Runnable() {
      @Override
      public void run() {
          cuberiteSTDOUT.writeString(line);
      }
  });
}

创建正常输出。

processScanner = new Scanner(process.getInputStream());
while(processScanner.hasNextLine()) {
  line = processScanner.nextLine();
  runOnUiThread(new Runnable() {
      @Override
      public void run() {
          System.out.println(line);
          cuberiteSTDOUT.writeString(line);
      }
  });
}

创建像

这样的疯狂输出

（这只是重复的一些行，但其他人遗漏了）

先谢谢

Answer 1

你的线在另一个线程中被操纵而不是被打印。将行更改为：

final String line = processScanner.nextLine();

Android：runOnUiThread混合输出
