尝试此功能

private void getdetails(String json){
    try {

        JSONArray result = new JSONArray(json);
        JSONObject c = result.getJSONObject(0);
        String mdp = c.getString("Password");
        String login = c.getString("Login");
        String type = c.getString("Type");
        String d = mdp;
        String d3 = type;
        if(d.equalsIgnoreCase(et_password.getText().toString())&& d3.equals("Delegue"))
        {
            Intent intent = new Intent(this,DetailsAccount.class);
            intent.putExtra("login", et_login.getText().toString());
            startActivity(intent);
        }
        else{
            Toast.makeText(MainActivity.this, "Merci de vérifier votre email et mot de passe", Toast.LENGTH_SHORT).show();
        }
    } catch (JSONException e) {
        e.printStackTrace();
    }
}

如果您的JSON字符串只是一个数组，则无法将其转换为对象。您只需从字符串本身构造一个JSON数组。

无法转换为JSONObject
