我有一个数据库。（XAMMP）我
能够得到所有的值。
我正在使用回收器视图并根据我的数据库中的值填充回收器视图。
我已经把recyclerview适配器放在onresponse里面了，
但是textviews的静态值没了。有没有更好的方法来填充 recyclerview(onBackground)？
public void getComments() {
final List<Comments> commentsData = new ArrayList<>();
Global.getCommentTitle.clear();

JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST,
showUrl, new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
try {

for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject = jsonArray.getJSONObject(i);
Global.getCommentTitle.add(jsonObject.getString("title"));
Global.getCommentPicture.add("drawable://" + R.drawable.juandirection_placeholder);
Global.getComment.add(jsonObject.getString("comment"));

Global.getCommentRating.add(Integer.parseInt(jsonObject.getString("rating")));

}

runOnUiThread(new Runnable() {

String[] header = {"Information", "Photos", "Reviews"};
for (int i = 0; i < header.length; i++) {

current.header = header[i];
headerData2.add(current);
}
mRecyclerView = (RecyclerView) findViewById(R.id.rvPOI);
adapter = new AdapterPOI(getApplicationContext(), headerData, headerData2, ratingData, commentsData);
mRecyclerView.setAdapter(adapter);
mRecyclerView.setLayoutManager(new LinearLayoutManager(getApplicationContext()));
mRecyclerView.addItemDecoration(new SimpleDividerItemDecoration(getApplicationContext()));
mRecyclerView.addOnItemTouchListener(new RecyclerTouchListener(getApplicationContext(), mRecyclerView, new ClickListener() {
@Override
public void onClick(View view, int position) {
if (position == 2) {
startActivity(new Intent(getApplicationContext(), ViewInformation.class));
}
if (position == 3) {

}
if (position >= 9 && position <= 13) {
Global.viewCommets = position - 9;
Global.singleComment = true;
startActivity(new Intent(getApplicationContext(), ViewComment.class));
}
if (position == 14) {
Global.singleComment = false;
startActivity(new Intent(getApplicationContext(), ViewComment.class));
}
}
@Override
public void onLongClick(View view, int position) {
}
}));
}
});
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
}
});
VolleyHelper.getInstance(getApplicationContext()).addToRequestQueue(jsonObjectRequest);
}
甚至 Recyclerview 的连锁反应也消失了。似乎是什么问题？
