Java.lang.numberformatexception：無效的浮點數“ 0.008466”

Question

我只是從一個php請求中獲取0.008466的值，並將其轉換為float但無法獲取。

我試圖使用numberFormat和DecimalFormat以及Float.parseFloat，但是沒有任何效果。

private void retrieveMinuteByDegreeValueFromPhp() throws IOException {
    SharedPreferences prefs = mContext.getSharedPreferences(SHARED_PREFS, 0);
    SharedPreferences.Editor editor = prefs.edit();

    HttpClient httpclient=new DefaultHttpClient();
    HttpPost httppost=new HttpPost(URL_PHP_MINUTEDEGREE);
    HttpResponse response = httpclient.execute(httppost);

    if ( response.getStatusLine().getStatusCode() == 200){
        String str =  EntityUtils.toString(response.getEntity());
        float minuteByDegree = Float.valueOf(str);
        if (minuteByDegree > 0){
            editor.putFloat(MINUTEBYDEGREE, minuteByDegree);
            editor.commit();
        }
        Log.d("MinuteByDegree","Minutebydegree : " + minuteByDegree);

    }
    else {
        Log.d("MinuteByDegee","Error : " + response.getStatusLine().getStatusCode());
    }
}

任何想法 ？

感謝@Thomas，字符串中隱藏了一個錯誤字符，但char Array中沒有。 :)
