//文件名称

private final static String fileName = "regison.json";

class DataThread extends Thread {    @Override    public void run() {        addStr = getJson(fileName);        Message msg = handler.obtainMessage(0);        handler.sendMessage(msg);    }

//读取方法

 public String getJson(String fileName) {        StringBuilder stringBuilder = new StringBuilder();        try {            AssetManager assetManager = SelectAreaActivity.this.getAssets();            BufferedReader bf = new BufferedReader(new InputStreamReader(                    assetManager.open(fileName)));            String line;            while ((line = bf.readLine()) != null) {                stringBuilder.append(line);            }        } catch (IOException e) {            e.printStackTrace();        }        return stringBuilder.toString();    }}
