将 MAMP（本地主机）数据加载到 EditText 问题 Android

Question

我有一个 MAMP（本地主机）数据库并加载了一个配置文件。我希望能够加载我的所有配置文件数据，例如我的多行编辑文本中的 9 个字段。

只有我的日志没有错误，它在检索数据时显示成功，但它只显示数据库中的一个字段，而不是所有字段...知道如何获取所有字段吗？我的 php 和其他一切都很好，因为我已经测试过了。

我想知道你是否可以帮助我？

我的Class:

  String pid;

    // Progress Dialog
    private ProgressDialog pDialog;

    // JSON parser class
    JSONParser jsonParser = new JSONParser();

    // single product url
    private static final String url_get_single_profile = "http://MYIP:8888/android_connect/get_all_profiles.php";


    // JSON Node names
    private static final String TAG_SUCCESS = "success";
    private static final String TAG_USERPROFILE = "UserProfile";
    private static final String TAG_PID = "pid";
    private static final String TAG_FIRSTNAME = "firstname";
    private static final String TAG_LASTNAME = "lastname";
    private static final String TAG_ADDRESS = "address";
    private static final String TAG_COMMENTS = "comments";
    private static final String TAG_AGE = "age";

您正在用每个项目覆盖 EditText 字段。要修复它，只需创建一个 StringBuilder 并连接每个可用的项目。然后，在提取完所有数据后，在底部调用 txtMessage.setText。

protected void onPostExecute(JSONObject product) {
    if (product != null) {
        // product with this pid found
        // Edit Text
        txtMessage = (EditText) findViewById(R.id.txtMessage);

        StringBuilder jsonStringBuilder = new StringBuilder(); //Create StringBuilder for concatenation of JSON results

        // display profile data in EditText
        try {
            //txtMessage.setText(product.getString(TAG_FIRSTNAME));  //Don't set the text here
            jsonStringBuilder.append(product.getString(TAG_FIRSTNAME)); //Concatenate each separate item
            jsonStringBuilder.append(System.getProperty("line.separator"));
        } catch (JSONException e) {
            e.printStackTrace();
        }
        try {
            //txtMessage.setText(product.getString(TAG_LASTNAME));
            jsonStringBuilder.append(product.getString(TAG_LASTNAME));
            jsonStringBuilder.append(System.getProperty("line.separator"));
        } catch (JSONException e) {
            e.printStackTrace();
        }
        try {
            //txtMessage.setText(product.getString(TAG_ADDRESS));
            jsonStringBuilder.append(product.getString(TAG_ADDRESS));
            jsonStringBuilder.append(System.getProperty("line.separator"));
        } catch (JSONException e) {
            e.printStackTrace();
        }
        try {
            //txtMessage.setText(product.getString(TAG_COMMENTS));
            jsonStringBuilder.append(product.getString(TAG_COMMENTS));
            jsonStringBuilder.append(System.getProperty("line.separator"));
        } catch (JSONException e) {
            e.printStackTrace();
        }
        try {
            //txtMessage.setText(product.getString(TAG_AGE));
            jsonStringBuilder.append(product.getString(TAG_AGE));
            jsonStringBuilder.append(System.getProperty("line.separator"));
        } catch (JSONException e) {
            e.printStackTrace();
        }
        try {
            //txtMessage.setText(product.getString(TAG_GENDER));
            jsonStringBuilder.append(product.getString(TAG_GENDER));
            jsonStringBuilder.append(System.getProperty("line.separator"));
        } catch (JSONException e) {
            e.printStackTrace();
        }
        try {
            //txtMessage.setText(product.getString(TAG_HEIGHT));
            jsonStringBuilder.append(product.getString(TAG_HEIGHT));
            jsonStringBuilder.append(System.getProperty("line.separator"));
        } catch (JSONException e) {
            e.printStackTrace();
        }
        try {
            //txtMessage.setText(product.getString(TAG_WEIGHT));
            jsonStringBuilder.append(product.getString(TAG_WEIGHT));
            jsonStringBuilder.append(System.getProperty("line.separator"));
        } catch (JSONException e) {
            e.printStackTrace();
        }
        try {
            //txtMessage.setText(product.getString(TAG_INFORMATION));
            jsonStringBuilder.append(product.getString(TAG_INFORMATION));
            jsonStringBuilder.append(System.getProperty("line.separator"));
        } catch (JSONException e) {
            e.printStackTrace();
        }
        txtMessage.setText(jsonStringBuilder.toString());
    }
