我使用以下公式获得总小时数：
public void updateTotalHours()
{
int a = SplitTime(objMyCustomBaseAdapter.getFistTime());
int b = SplitTime(objMyCustomBaseAdapter.getLastTime());
long difference = 0;
if (a > b) {
difference = (b + (24 * 60) - a) - (1 * 60);
int minutes = (int) (difference % 60);
int hours = (int) ((difference / 60) % (24 * 60));
totalHours.setText(("Total hours : " + hours + ":" + minutes));
} else {
difference = (b - a) - (1 * 60);
int minutes = (int) (difference % 60);
int hours = (int) ((difference / 60) % (24 * 60));
totalHours.setText(("Total hours : " + hours + ":" + minutes));
}
}
}
得到后全部小时数，我试图将其转换为String并保存到MySQL
TotalHours=totalHours.getText().toString();
String[] time= TotalHours.split(":", 2);
Toast.makeText(getApplicationContext(),time[1].trim(),Toast.LENGTH_LONG).show();
addInformation(name, weather, date2, status, first1[1], last1[1],time[1]);
添加信息
public class AddInfo extends AsyncTask<String, Void, ContentValues> {
private final Context context;
ProgressDialog loading;
public AddInfo(Context context) {
this.context = context;
}
private ContentValues handleActionSend(String name, String weather, String date2, String status, String timeIn, String timeOut, String hours) {

retour.put("success", false);

BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
StringBuilder result = new StringBuilder();
String line;
while ((line = rd.readLine()) != null) {
result.append(line);

JSONObject json = new JSONObject(result.toString());

lastID = contentValues.getAsString("lastId");
Toast.makeText(getApplicationContext(), "D" + lastID, Toast.LENGTH_LONG).show();
} else {

}
Toast.makeText(context, message, Toast.LENGTH_LONG).show();
} else {

}
}
public void addInformation(final String name, final String weather, final String date2, final String status, final String timeIn, final String timeOut, final String hours) {
AddInfo ru = new AddInfo(this);
ru.execute(name, weather, date2, status, timeIn, timeOut,hours);
}
添加信息.php
<?php
require_once('dbConnect.php');
if($_SERVER['REQUEST_METHOD']=='POST'){
$response = array();
//Getting values
$name = $_POST['name'];
$weather = $_POST['weather'];
$date = $_POST['date'];
$status = $_POST['status'];
$timeIn = $_POST['timeIn'];
$timeOut = $_POST['timeOut'];
$hours = $_POST['totalHours'];
print_r($hours);
//Creating an sql query
$sql = "INSERT INTO information(name, weather, date, status, time_in, time_out, total_hours) VALUES ('$name','$weather','$date', '$status', '$timeIn', '$timeOut', '$hours')";
//Importing our db connection script
require_once('dbConnect.php');
//Executing query to database
if(mysqli_query($con,$sql)){
//echo 'Information Added Successfully';
$insertId= mysqli_insert_id($con);
$response["lastId"]=$insertId;
echo json_encode($response);
}else{
echo 'Could Not Add Information';
}
//Closing the database
mysqli_close($con);
}
?>
所有数据都可以插入MySQL，只是total_hours始终为0。我想知道错误是否来自这一行？
TotalHours=totalHours.getText().toString();
发生错误！异常错误：值<br类型的
java.lang.String 无法转换为 JSONObject。
