java - 如何将 2 个或多个值放入 ArrayList

Question

我想知道如何将多个值放入 ArrayList<NameValuePair> .这是我的代码，但它不起作用。有人帮我解释一下 ArraysList<NameValuePair> 。这是我的代码:

public void OnClickForSave(View v) throws Exception {
    String st = null;
    String str = null;
    String response = null;
    String memberID = "000000007";
    String teamID = "000007";
    ArrayList<NameValuePair> postParameters = new ArrayList<NameValuePair>();
    postParameters.add(new BasicNameValuePair("userID", memberID));
    postParameters.add(new BasicNameValuePair("teamID", teamID));

    if (v.getId() == (R.id.imgbtn_layout2)) {
        Intent intent = new Intent(this, IntentTesting.class);
        startActivity(intent);
    }

    if (v.getId() == (R.id.imgbtn_lsave)) {
        if (txt_teamID.getText().toString().trim().equals(null)
                || txt_teamID.getText().toString().trim().equals("")) {
            AlertDialog empty = createDialogEmpty(this, "Enter Team ID");
            empty.show();
            txt_teamID.selectAll();
            txt_teamID.requestFocus();
        }
        else if (txt_teamID.getText().toString().trim().length() > 6) {
            AlertDialog notFormat = createDialogEmpty(this, "More Than 6 Characters");
            txt_teamID.selectAll();
            txt_teamID.requestFocus();
            notFormat.show();
        } else {
            try {
                st = CustomHttpClient.executeHttpGet("http://192.168.200.14/football365/DBConnection.php");
                str = CustomHttpClient.executeHttpGet("http://192.168.200.14/football365/responseJson.php");
                response = CustomHttpClient.executeHttpPost("http://192.168.200.14/football/joinTeam.php",
                        postParameters);
            } catch (JSONException e) {
                e.printStackTrace();
            }
        }
    }
}

支持哥们吗？在这种情况下，只需使用 params 的 add 函数即可。不强制使用特定大小进行初始化。

List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("Key1", "Value1"));
params.add(new BasicNameValuePair("Key2", "Value"));

你将会得到这样的东西

键1 = 值1；键2 = 值

希望有效果
