android - 如何从 MySql 数据库检索微调器数据的值

Question

我正在尝试开发更新表单。我在显示性别微调器的值时遇到问题。在我的 MySql 数据库中，性别值为 Male。现在我必须在微调器中显示该值。

这是编辑患者的代码。

        ArrayAdapter adapter = ArrayAdapter.createFromResource(
                          this, R.array.gender_array, android.R.layout.simple_spinner_item);
                          adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown

    _item);


protected String doInBackground(String... params) {

            // updating UI from Background Thread
            runOnUiThread(new Runnable() {
                public void run() {
                    // Check for success tag
                    int success;
                    try {
                        // Building Parameters
                        List<NameValuePair> params = new ArrayList<NameValuePair>();
                        params.add(new BasicNameValuePair("uid", uid));

                        // getting product details by making HTTP request
                        // Note that product details url will use GET request
                        JSONObject json = jsonParser.makeHttpRequest(

                        // check your log for json response
                        Log.d("Single Patient Details", json.toString());

                        // json success tag
                        success = json.getInt(TAG_SUCCESS);

Answer 1

您必须在 string.xml 文件中声明一个字符串数组

<string-array name="gender">
        <item>Male</item>
        <item>Female</item>
</string-array>

从数据库检索数据后

if(gender.equalsIgnoreCase("male"){
      youeSpinner.setSelection(0);
}
else if(gender.equalsIgnoreCase("female"){
      youeSpinner.setSelection(1);
}
