/** * 【文件操作】 */package Iwit.IwitTest;
import java.io.FileInputStream;import java.io.FileOutputStream;import java.io.IOException;import java.io.InputStreamReader;import java.io.OutputStreamWriter;
import android.content.Context;import android.widget.Toast;
/** * @author Shine *【文件读，写】 */public class FileOperate { /** * 【读取文件】 * @param context * @param fileName * @return */ public String ReadText(Context context,String fileName) { FileInputStream fIn = null; InputStreamReader isr = null; char[] inputBuffer = new char[255]; String data = null; try { fIn =context.openFileInput(fileName); isr = new InputStreamReader(fIn); isr.read(inputBuffer); data = new String(inputBuffer); Toast.makeText(context, "read Succeed",Toast.LENGTH_SHORT).show(); } catch (Exception e) { e.printStackTrace(); Toast.makeText(context, " not read",Toast.LENGTH_SHORT).show(); } finally { try { isr.close(); fIn.close(); } catch (IOException e) { e.printStackTrace(); } } return data; } /** * 【写入文件】 * @param context * @param fileName * @param data */ public void WriteText(Context context, String fileName,String data) { FileOutputStream fOut = null; OutputStreamWriter osw = null; try{ fOut =context.openFileOutput(fileName, 1); osw = new OutputStreamWriter(fOut); osw.write(data); osw.flush(); Toast.makeText(context, " saved",Toast.LENGTH_SHORT).show(); } catch (Exception e) { e.printStackTrace(); Toast.makeText(context, " not saved",Toast.LENGTH_SHORT).show(); } finally { try { osw.close(); fOut.close(); } catch (IOException e) { e.printStackTrace(); } } }}
