自定义了一个方法，每次重新加载recyclerView都调用这个方法，但是加载之后item间距每次都比原先的大一倍，请问我在调用这个方法的时候该怎么处理？
//名师风采
private void initTeacherData(final String url) {
Log.d("名师风采：", url);
mExTeacherList.clear();
//TODO
HttpUtil.sendOkHttpRequest(url,new okhttp3.Callback(){
@Override
public void onResponse(Call call, Response response) throws IOException {
try {
JSONObject newsJsonObject = new JSONObject(response.body().string());
JSONArray newsItems = newsJsonObject.getJSONArray("items");
for (int i = 0; i < newsItems.length(); i++) {
String description = newsItems.getJSONObject(i).getString("description");
String title = newsItems.getJSONObject(i).getString("title");
String start_time = newsItems.getJSONObject(i).getString("start_time");
JSONArray newsImageData = newsItems.getJSONObject(i).getJSONArray("pic_describe");
String teacherUrl = newsImageData.getJSONObject(0).getString("pic_path2");
String teacherUrl2="http://192.168.1.247:8081/obpm"+teacherUrl;
Log.d("名师风采：", title);
Log.d("名师风采：", description);
Log.d("名师风采：", start_time);
mExTeacherList.add(new ExTeacher(null,description,teacherUrl2,title,start_time));
}
runOnUiThread(new Runnable() {
@Override
public void run() {
mLayoutManager = new LinearLayoutManager(CampusChildActivity.this, LinearLayoutManager.HORIZONTAL, false);
mAdapter = new ChCampusTeacherAdapter(mExTeacherList);
mRecyclerView.setLayoutManager(mLayoutManager);
mRecyclerView.addItemDecoration(new MyDividerItemDecoration(CampusChildActivity.this, LinearLayoutManager.HORIZONTAL));自定义设置间隔
// 设置adapter
mRecyclerView.setAdapter(mAdapter);
mTvCurrentPage.setText("当前页："+mIntPageCount);
}
});
} catch (JSONException e) {
e.printStackTrace();
}
}
@Override
public void onFailure(Call call, IOException e) {
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(CampusChildActivity.this,"二级页面名师风采获取失败",Toast.LENGTH_SHORT).show();
}
});
}
});
}
