如何从EditText获取纯文本而不是"android.support.v7.widget.AppCompatEditText {e67388"

如何从用户实际键入的EditText小部件中获取文本,我不断在我的数据库中获取此文本:"android.support.v7.widget.AppCompatEditText {e67388".

我收到此回复:注册响应:{"error":false,"uid":"56807035b02430.42354570","user":{"first_name":"Tom","last_name":"Black","email" :"tom@tom.com","pets_race":"android.support.v7.widget.AppCompatEditText {e67388","pets_name":"android.support.v7.widget.AppCompatEditText {2c8d71","created_at":" 2015年12月28"日, "的updated_at":空}}

我正在使用wamp服务器.以下是与DB有关的所有文件:

来自DB_Functions.php的storeUser方法:

function __destruct(){

    $stmt = $this->conn->prepare("Insert INTO users(unique_id, first_name, last_name, email, encrypted_password, pets_race,pets_name,salt,created_at) values (?,?,?,?,?,?,?,?,NOW())");
    $stmt->bind_param("ssssssss",$uuid,$first_name,$last_name, $email,$encrypted_password,$pets_race,$pets_name,$salt);
    $result = $stmt->execute();
    $stmt->close();

    //check for successfull store
    if($result){
        $stmt = $this->conn->prepare("select * from users where email = ?");
        $stmt->bind_param("s",$email);
        $stmt->execute();
        $user = $stmt->get_result()->fetch_assoc();
        $stmt->close();

        return $user;
    }else{
        return false;
    }

需要帮助请叫我.谢谢

要从中检索纯文本EditText,请使用getText().toString(),而不仅仅是toString().
