android编程：读取txt文件

 

首先把ｔｘｔ文本加载到ａｎｄｒｏｉｄ虚拟机上面：

  用ｆｉｌｅ　ｅｘｐｌｏｒｅｒ直接把ｔｘｔ文本放到ｃｄｃａｒｄ的目录上

StringBuffer buffer = new StringBuffer();
  	      try {
  	      FileInputStream fis = new FileInputStream("/sdcard/XXX.txt");
InputStreamReader isr = new InputStreamReader(fis,"GB2312");//文件编码Unicode,UTF-8,ASCII,GB2312,Big5
  	      Reader in = new BufferedReader(isr);
  	      int ch;
  	      while ((ch = in.read()) > -1) {
  	          buffer.append((char)ch);
  	                            }
  	      in.close();
  	      tv.setText(buffer.toString());  //buffer.toString())就是读出的内容字符 
	      } catch (IOException e) {
  	    	tv.setText("文件不存在!")
  	      }
