Android 讀取檔案字串API

 

import android.util.Log;
import java.io.BufferedReader;
import java.io.File;
import java.io.FileInputStream;
import java.io.InputStreamReader;

public class File_reader_tool {

    public  static String TAG="File_reader_tool";



    public  interface  Get_String_line_event{


        public  void get_string(String line);
    }

    public  Get_String_line_event event=null;
    public  void load(File file){

        if(event==null)return;
        FileInputStream is;
        BufferedReader reader;

        try {
            is = new FileInputStream(file);
            reader = new BufferedReader(new InputStreamReader(is));
            String line = reader.readLine();
            while (line != null) {

             //   Log.d("TTT", line);
                event.get_string(line);
                line = reader.readLine();

            }

            is.close();
            reader.close();
        }catch (Exception e){

            Log.e(TAG,e.getMessage());
        }



    }


}

使用方法:

File_reader_tool reader_tool=new File_reader_tool();
reader_tool.event=new File_reader_tool.Get_String_line_event() {
    @Override
    public void get_string(String line) {
        //字串處理
    }
};
File file = new File("your path");
reader_tool.load(file);
