Question

我在我的android项目中使用了volley。在这种情况下，我必须增加布局。一切正常。但是在膨胀布局中，我将setText使用TextView。而且布局膨胀是基于API数组长度的循环。它正确循环。

JsonObjectRequest innerLiveRequest = new JsonObjectRequest
            (Request.Method.GET, liveURL, null, new Response.Listener<JSONObject>() {
                @Override
                public void onResponse(JSONObject response) {
                    try {
                        JSONArray liveArray = response.getJSONArray("data");
                        for (int i = 0; i < liveArray.length(); i++) {
                            JSONObject data = liveArray.getJSONObject(i);

                            String liveID = data.getString("id");
                            final String league_id = data.getString("league_id");
                            final String localteam_id = data.getString("localteam_id");
                            final String visitorteam_id = data.getString("visitorteam_id");
                            final String localScore = data.getJSONObject("scores").getString("localteam_score");
                            final String visitorScore = data.getJSONObject("scores").getString("visitorteam_score");
                            final String minute = data.getJSONObject("time").getString("minute");
                            final String willStart = data.getJSONObject("time").getJSONObject("starting_at").getString("time");

                            if (league_id.equals(leagueID)) {
                                layout.addView(LayoutInflater.from(getContext()).inflate(R.layout.layout_expanded_layout, layout, false));

                                TextView minutesPlaying = layout.findViewById(R.id.minutes);
                                TextView local = layout.findViewById(R.id.localTeam);
                                TextView visitor = layout.findViewById(R.id.visitorTeam);
                                TextView localScoreText = layout.findViewById(R.id.localTeamScore);
                                TextView visitorScoreText = layout.findViewById(R.id.visitorTeamScore);

                                local.setText(localteam_id);
                                visitor.setText(visitorteam_id);
                                localScoreText.setText(localScore);
                                visitorScoreText.setText(visitorScore);//Log.i("ITER", liveId);
                            }
                        }
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                }
            }, new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {
                    error.printStackTrace();
                }
            });
    Volley.newRequestQueue(getContext()).add(innerLiveRequest);

但是setText仅在第一次迭代中有效。其余的迭代布局为空。帮我修复它

尝试分别获取inflated view，然后在该view中进行操作。希望对您有帮助。

View view = LayoutInflater.from(getContext()).inflate(R.layout.layout_expanded_layout, layout, false);
layout.addView(view);

TextView minutesPlaying = view.findViewById(R.id.minutes);
TextView local = view.findViewById(R.id.localTeam);
TextView visitor = view.findViewById(R.id.visitorTeam);
TextView localScoreText = view.findViewById(R.id.localTeamScore);
TextView visitorScoreText = view.findViewById(R.id.visitorTeamScore);

local.setText(localteam_id);
visitor.setText(visitorteam_id);
localScoreText.setText(localScore);
visitorScoreText.setText(visitorScore);

由于layout.findViewById始终返回其第一个孩子的view。

如何在膨胀布局中设置setText？
