檔案上傳

private TextView tv_file;
    private static String PATH = "http://192.168.37.2:8080/http/fileuploadServlet";

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        setContentView(R.layout.activity_main);
        tv_file = (TextView) findViewById(R.id.tv_file);
    }

    //檔案上傳，從本地上傳到伺服器
    public void click(View view) throws FileNotFoundException{

        //獲取本地圖片地址/mnt/sdcard/10.jpg
        String filePath = tv_file.getText().toString().trim();

        AsyncHttpClient httpClient = new AsyncHttpClient();

        RequestParams params = new RequestParams();
        File file = new File(filePath);
        params.put("file", file);

        httpClient.post(PATH, params,new TextHttpResponseHandler() {

            @Override

                    String responseString) {
                Toast.makeText(MainActivity.this, responseString, Toast.LENGTH_SHORT).show();
            }

            @Override
