Question

我有一个由{Shortlist'按钮组成的ListView，如果有人点击该按钮，则应更改按钮文本。按钮Shortlist通货膨胀，其中shortlist [position] .toString（）值来自服务器，如果按钮文本被列入候选名单，则它将显示在按钮上，按钮将不会被按下。如果按钮文本是候选名单，那么它将在按钮上显示为候选名单并按下按钮。

以下是我的代码。

public class Profile_Match_custom_List  extends ArrayAdapter<String>  {
private static final String url ="http://10.0.2.2/xp/shortlist1.php";
private static final String url1 = "http://10.0.2.2/xp/express_intrest.php";
private static final String KEY_MATRI_ID_TO="matriID_to";
private static final String KEY_MATRI_ID_BY="matriID_by";

SessionManager session;
public String matri_id_to, matri_id_by, str_gender;

String str;

public Button btnSort;
private NetworkImageView imageView;
private ImageLoader imageLoader;
private final String[] ids;
private String[] ages;
private String[] heights;
public String[] communities;
public String[] castes;
public String[] educations;
public String[] occupations;
public String[] incomes;
public String[] pics;
public String[] locations;
public String[] shortlist;
public String[] expressinterest;
private Activity context;

您没有刷新列表数据。保存点击已完成的位置，然后根据此位置获取或放置数据。

btnSort.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        matri_id_to=ids[position]; //You can totally discard this line as you can get this value directly on getParams from selectedPosition.
        selectedPosition = position;
        shortlist();
    }
});

//短名单方法。

private void shortlist(){
StringRequest stringRequest = new StringRequest(Request.Method.POST, url, new Response.Listener<String>     () {
    @Override
    public void onResponse(String response) {
        Log.e("***short response----",response.trim());
        if(response.trim().equalsIgnoreCase("success")) {

            shortlist[selectedPosition] = "shortlisted";
            notifyDataSetChanged(); //this will refresh your list and your code for disabling the button will work
        }
    }
},
        new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                Toast.makeText(getContext(), error.toString(), Toast.LENGTH_LONG).show();
            }
        }) {
    @Override
    protected Map<String, String> getParams() {
        Map<String, String> params = new HashMap<String, String>();
        params.put(KEY_MATRI_ID_BY,matri_id_by);
        params.put(KEY_MATRI_ID_TO,matri_id_to);
        return params;
    }
};
RequestQueue requestQueue = Volley.newRequestQueue(getContext());
requestQueue.add(stringRequest);
}

执行shortlist[selectedPosition] = "shortlisted"并调用notifyDataSetChanged()后，您的适配器将刷新并调用getView。您设置btnSort的if..else代码将起作用，并将在候选名单数组中找到selectedPosition作为＆＃34;列入短名单＆＃34;并将产生你想要的输出。
