1：通过新建data/data下面创建文件，里面创建Key=Value来保存

保存数据

public boolean saveFile(){
    	Properties properties = new Properties();
    	properties.put("musicFlag", String.valueOf(boolFlag));
    	
    	try{
    		FileOutputStream outStream = this.openFileOutput("music.cfg",Context.MODE_WORLD_WRITEABLE);
    		properties.store(outStream,"");
    		
    	}catch(Exception e){
    		e.printStackTrace();
    		return false;
    	}
    	
    	return true;
    }

读取数据

    public boolean loadFile(){
    	Properties properties = new Properties();
    	
    	try{
    		FileInputStream inStream = this.openFileInput("music.cfg");
    		properties.load(inStream);
    	}catch(Exception e){
    		e.printStackTrace();
    		return false;
    	}
    	Log.v("TAG","out数据是："+properties.get("musicFlag").toString());
    	
    	boolFlag = Boolean.valueOf(properties.get("musicFlag").toString());
    	   	
    	return true;
    }
