我收到错误，getLayountInflator（Bundle）不能在片段内使用。
我有这个JSONAdapter.java
public class JSONAdapter extends BaseAdapter{
Context mContext;
LayoutInflater mInflater;
JSONArray mJsonArray;
public JSONAdapter(Context context, LayoutInflater inflater) {
mContext = context;
mInflater = inflater;
mJsonArray = new JSONArray();
}
@Override
public int getCount() {
return mJsonArray.length();
}
@Override
public Object getItem(int position) {
return mJsonArray.optJSONObject(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = mInflater.inflate(R.layout.article_list, parent, false);
holder = new ViewHolder();
holder.thumbnailImageView = (ImageView) convertView.findViewById(R.id.img_thumbnail);
holder.titleTextView = (TextView) convertView.findViewById(R.id.text_title);
holder.categoryTextView = (TextView) convertView.findViewById(R.id.text_category);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
JSONObject jsonObject = (JSONObject) getItem(position);
String imageURL = jsonObject.optString("some_image_url");
Picasso.with(mContext).load(imageURL).placeholder(R.mipmap.impakt_icon).into(holder.thumbnailImageView);
String articleTitle = "";
String categoryName = "";
categoryName = jsonObject.optJSONObject("featured_categories_name").optString("cat_name");
}
holder.titleTextView.setText(articleTitle);
holder.categoryTextView.setText(categoryName);
return convertView;
}
private static class ViewHolder {
public ImageView thumbnailImageView;
public TextView titleTextView;
public TextView dateTextView;
public TextView categoryTextView;
}
public void updateData(JSONArray jsonArray) {
mJsonArray = jsonArray;
}
}
和这个布局适配器SlidingTabsBasicFragment.java
public class SlidingTabsBasicFragment extends ListFragment {
static final String LOG_TAG = "SlidingTabsBasicFragment";
private SlidingTabLayout mSlidingTabLayout;
private ViewPager mViewPager;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_sample, container, false);
}
@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
mViewPager = (ViewPager) view.findViewById(R.id.viewpager);
mViewPager.setAdapter(new SamplePagerAdapter());
mSlidingTabLayout = (SlidingTabLayout) view.findViewById(R.id.sliding_tabs);
mSlidingTabLayout.setViewPager(mViewPager);
}
class SamplePagerAdapter extends PagerAdapter implements View.OnClickListener {
ListView lstTest;
JSONAdapter mJSONAdapter;
String tabs[]={"Item 1","Item 2","Item 3","Item 4","Item 5","Item 1","Item 1","Item 1"};
/**
* @return the number of pages to display
*/
@Override
public int getCount() {
return tabs.length;
}
/**
* @return true if the value returned from {@link #instantiateItem(ViewGroup, int)} is the
* same object as the {@link View} added to the {@link ViewPager}.
*/
@Override
public boolean isViewFromObject(View view, Object o) {
return o == view;
}
@Override
public CharSequence getPageTitle(int position) {
return tabs[position];
}
@Override
public Object instantiateItem(ViewGroup container, int position) {
View view=null;
if(position%2==0){
view = getActivity().getLayoutInflater().inflate(R.layout.pager_item,container, false);
lstTest = (ListView) view.findViewById(R.id.home_list);
Button but = (Button) view.findViewById(R.id.button1);
mJSONAdapter = new JSONAdapter(getActivity(),getLayoutInflater());
// Set the ListView to use the ArrayAdapter
lstTest.setAdapter(mJSONAdapter);
but.setOnClickListener(this);
}else{
view = getActivity().getLayoutInflater().inflate(R.layout.economics_pager_item,container, false);
}
// Add the newly created View to the ViewPager
container.addView(view);
// Retrieve a TextView from the inflated View, and update it's text
TextView title = (TextView) view.findViewById(R.id.item_title);
title.setText(String.valueOf(position + 1));
return view;
}
View view=null;
if(position%2==0){
view = activity.getLayoutInflater().inflate(R.layout.home_page_item,container, false);
}else{
view = activity.getLayoutInflater().inflate(R.layout.ekonomia_page_item,container, false);
}
container.addView(view);
// Retrieve a TextView from the inflated View, and update it's text
TextView title = (TextView) view.findViewById(R.id.item_title);
title.setText(tabs[position]);
// Return the View
return view;
}
@Override
public void destroyItem(ViewGroup container, int position, Object object) {
container.removeView((View) object);
@Override
public void onClick(View v) {
queryImp();
}
private void queryImpakt() {
// Create a client to perform networking
AsyncHttpClient client = new AsyncHttpClient();
// Have the client get a JSONArray of data
// and define how to respond
client.get("http://xxxxxxx",
new JsonHttpResponseHandler() {
@Override
public void onSuccess(JSONArray jsonArray) {
// Display a "Toast" message
// to announce your success
// Toast.makeText(getApplicationContext(), "Success!", Toast.LENGTH_LONG).show();
// update the data in your custom method.
mJSONAdapter.updateData(jsonArray);
mJSONAdapter.notifyDataSetChanged();
}
@Override
public void onFailure(int statusCode, Throwable throwable, JSONObject error) {
// Display a "Toast" message
// to announce the failure
// Toast.makeText(getApplicationContext(), "Error: " + statusCode + " " + throwable.getMessage(), Toast.LENGTH_LONG).show();
// Log error message
// to help solve any problems
}
});
}
}
}
让我错误的一行是：
mJSONAdapter = new JSONAdapter(getActivity(),getLayoutInflater());
on JSONAdapter.java
我该如何解决，我需要做什么
答案 0 :(得分：1)
您可以使用getActivity().getLayoutInflater()来检索活动的LayoutInflater对象。
更改
mJSONAdapter = new JSONAdapter(getActivity(), getLayoutInflater());
与
mJSONAdapter = new JSONAdapter(getActivity(), getActivity().getLayoutInflater());
