hi i am trying to add a list view to an alert dialog. on click of the ok button on my first alert dialog, the program directs to the response fragment which contains a second dialog box which needs to be populated with the list view. the problem i am having is that i am getting an empty alert box with the list view showing behind it on the fragment
public class ResponseFragment extends Fragment {
ListView list;
private String urlString;
ArrayList<HashMap<String, String>> oslist = new ArrayList<HashMap<String, String>>();
#Override

String urlString = strings[0];
HTTPDataHandler hh = new HTTPDataHandler();
stream = hh.GetHTTPData(urlString);

System.out.println(stream);
return stream;

I think you want to show a ListView inside the AlertDialog . So, You need to modify some of your code.
1st :
You inflate the listview from the fragment_response layout. Which is not necessary. In onCreateView() method just initialize a new object of ListView.
Replace :
list=(ListView)v.findViewById(R.id.listviewResp);
By
list = new ListView(getActivity());
2nd:
Change this Code :
AlertDialog alertDialog = new AlertDialog.Builder(
getActivity()).create();
alertDialog.setTitle("easyQ");
alertDialog.setMessage("reason");
LayoutInflater inflater = (getActivity()).getLayoutInflater();
final View dialogView=inflater.inflate(R.layout.fragment_response,null);
alertDialog.setView(dialogView);
alertDialog.show();
alertDialog.show();
By
AlertDialog alertDialog = new AlertDialog.Builder(getActivity()).create();
alertDialog.setTitle("easyQ");
alertDialog.setMessage("reason");
alertDialog.setView(listView);
alertDialog.show();
If other code is ok, then i hope it will work well.

You are creating an array adapter with the contructor where u are just giving 3 parameters- context, layout Id and the row-Items.
So for your constructor with only 3 parameters R.layout.item must be the id of a XML layout file containing only a TextView(the TextView can't be wrapped by another layout, like a LinearLayout, RelativeLayout etc!), something like this:
But in your case, you are using a complex layout So in that case you need to pass both layout id and Textview id in the constructor.
In case u need you don't have textViewId you can pass textViewId as 0.
like this
public arrayadapter(Context context, int resource_id, List<cards> items)
{
super(context,resource_id,0,items);
}
If u have a textview ResourceId you can pass the resourceid in place of 0
public arrayadapter(Context context, int resource_id,int textViewId, List<cards> items)
{
super(context,resource_id,textViewId,items);
}

getLayoutInflater() in fragment
(5 answers)
Closed 4 years ago.
I'm trying to code an app that downloads data of some events from an online MySQL database and writes it into my android app. Right now, what i'm trying to do is just testing if downloading the name of the event works, but i keep getting this error:
java.lang.NoSuchMethodError: No virtual method getLayoutInflater()Landroid/view/LayoutInflater; in class Lcom/suspicio/appfisio_business/FrammentoCorsi; or its super classes (declaration of 'com.suspicio.appfisio_business.FrammentoCorsi' appears in /data/app/com.suspicio.appfisio_business-1/split_lib_slice_8_apk.apk)

which points to the line:
listViewItem = getLayoutInflater().inflate(R.layout.frammento_corsi, null, true);

Can you help me out?
Thanks in advance!
Use this
LayoutInflater layoutInflater = LayoutInflater.from(getContext());
listViewItem = layoutInflater.inflate(R.layout.frammento_corsi, null ,true);
Instead of this
listViewItem = getLayoutInflater().inflate(R.layout.frammento_corsi, null, true);
The application crashes when I tried to retrieve the JSON object to be used from searchActivity.java to searchDetail.java. It seems that the function getInfo() causes this problem. Initially, the list_data in getInfo() has size of 10, however after calling it from the searchActivity.java, the size becomes 0. Thus, may I know what can I do to solve this problem?

First execute the DataParser class ..new DataParser( lv).execute() or in ur case dp.execute() u are missing this statement.. If you are not executing the AsyncTask class it wont do any task in doInBackground(). Hopefully it will solve your problem.. dp.getinfo() will always return a blank list... make another class called class holdHashmapList {
public static ArrayList<Hashmap<String,String>> map= new ArrayList<>();} and in dataParser class holdHashmapList.map =getInfo();} and in onItemClick listener...Arralist<map<>> = holdHashmapList.map; Your hashmap that u are building will always contain the last last object... in parseData function... so before of data.put("id"); just add data=new HashMap<>();
you have to execute DataParser(dp) in order to populate your list_data in SearchActivity. only initializing DataParser won't populate the list_data.
public class searchActivity extends AppCompatActivity{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_search);
ListView lv= (ListView) findViewById(R.id.HerbListView);
Downloader dl = new Downloader(searchActivity.this,urlAddress,lv);
dl.execute();
final DataParser dp = new DataParser(lv);
dp.execute(); // update
lv.setOnItemClickListener (new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long

I have ViewPager that containing 3 different Fragment. each Fragment containing A Different View and also ListView, I got a problem when I was trying to show the ListView in one of Fragment from ViewPager, it doesn't show anything. I've tried to debug my adapter and it seems my getView() method is not called. I try to call my Fragment not from ViewPager, the result is getView() is called from adapter and ListView is showing. Is there any problem to show ListView from ViewPager? I have tried this solution by calling my adapter from onViewCreated() but there's nothing change. so is there any wrong with my method? this is my code :
My Fragment Class for Managing ViewPager
public class Frag_Provider extends Fragment {
private String[] tabsTitles = {"TERDEKAT", "SEMUA", "PROVIDERKU"};
String url = "";
List<ModelProvider> list_provider;
DB_Esehat db_esehat = null;
SQLiteDatabase db = null;
ContentLoadingProgressBar progressbar;
TabLayout tabLayout;
ViewPager pager;
public Frag_Provider (){
}
#Override
public View onCreateView(LayoutInflater inflater,
ViewGroup container,
Bundle savedInstanceState) {
((MainActivity) getActivity()).custom_toolbar("Provider", R.color.toolbar_provider, R.color.toolbar_provider_dark);
View result=inflater.inflate(R.layout.fragment_provider, container, false);
list_provider = new ArrayList<ModelProvider>();
progressbar = (ContentLoadingProgressBar)result.findViewById(R.id.progressbar);
db_esehat = new DB_Esehat(getActivity());
db = db_esehat.getWritableDatabase();
db.delete("LST_PROVIDER", null, null);
pager=(ViewPager)result.findViewById(R.id.pager);
tabLayout = (TabLayout)result.findViewById(R.id.sliding_tabs);
url = getResources().getString(R.string.url_host)+getResources().getString(R.string.url_provider);
new ProviderTask(url).execute();
pager.setAdapter(buildAdapter(tabsTitles));
tabLayout.post(new Runnable() {
#Override
public void run() {
tabLayout.setupWithViewPager(pager);
}
});
return(result);
}
public class ProviderTask extends AsyncTask<String, Void, String> {
String url = "";
public ProviderTask(String url) {
this.url = url;
}
#Override
protected void onPreExecute() {
super.onPreExecute();
progressbar.setVisibility(View.VISIBLE);
}
#Override
protected String doInBackground(String... params) {
String result = "";
try {
result = Connection.get(url);
} catch (Exception e) {
result = "";
}
return result;
}
#Override
protected void onPostExecute(String result) {
progressbar.setVisibility(View.GONE);
pager.setVisibility(View.VISIBLE);
tabLayout.setVisibility(View.VISIBLE);
super.onPostExecute(result);
if (result.equals("") || result.equals(null)) {
MethodSupport.AlertDialog(getActivity());
} else {
try {
JSONArray Data = new JSONArray(result);
for (int i = 0; i < Data.length(); i++) {
String LSKA_NOTE = "";
String RSALAMAT = "";
String RSTELEPON = "";
String RSNAMA = "";
String MAPPOS = "";
int RSTYPE = 0;
int RSID = 0;
int RS_NTT = 0;
JSONObject json = Data.getJSONObject(i);
if (json.has("LSKA_NOTE")) {
LSKA_NOTE = json.getString("LSKA_NOTE");
}
if (json.has("RSALAMAT")) {
RSALAMAT = json.getString("RSALAMAT");
}
if (json.has("RSTELEPON")) {
RSTELEPON = json.getString("RSTELEPON");
}
if (json.has("RSNAMA")) {

}
if (json.has("MAPPOS")) {

}
if (json.has("RSTYPE")) {

}
if (json.has("RSID")) {

}
if (json.has("RS_NTT")) {

}
db_esehat.InsertRS(LSKA_NOTE, RSALAMAT, RSTELEPON, RSNAMA, MAPPOS, RSTYPE, RSID, RS_NTT);
}
} catch (Exception e) {
Log.d("TES", e.getMessage());
}
}
}
}
private PagerAdapter buildAdapter(String[] tabsTitles) {
return(new FragmentStatePagerAdapter(getActivity(), getChildFragmentManager(),tabsTitles));
}
}
This is FragmentStatePagerAdapter.java
public class FragmentStatePagerAdapter extends FragmentPagerAdapter {
Context ctxt=null;
private String[] tabsTitles;
public FragmentStatePagerAdapter(Context ctxt, FragmentManager mgr, String[] tabsTitles) {
super(mgr);
this.ctxt=ctxt;
this.tabsTitles = tabsTitles;
}
#Override
public int getCount() {
return tabsTitles.length;
}
#Override
public Fragment getItem(int position) {
switch(position) {
case 0:
return Frag_Provider_Terdekat.newInstance(position);
case 1:
return Frag_Provider_Semua.newInstance(position);
case 2:
return Frag_Provider_Ku.newInstance(position);
}
return null;
}
// #Override public float getPageWidth(int position) { return(0.7f); }
#Override
public String getPageTitle(int position) {
return tabsTitles[position];
}
}
this is my Fragment_Provider.xml, Layout for managing my ViewPager
<?xml version="1.0" encoding="utf-8"?>

</RelativeLayout>
This is of my Fragment in ViewPagerthat containing ListView :
public class Frag_Provider_Terdekat extends Fragment {
private static final String KEY_POSITION="position";
private ListView list_provider;
List<ModelProviderTerdekat> list_ekamedicare;
DB_Esehat db_esehat;
SQLiteDatabase db;
ProviderTerdekatAdapter adapter;
static Frag_Provider_Terdekat newInstance(int position) {
Frag_Provider_Terdekat frag=new Frag_Provider_Terdekat();
Bundle args=new Bundle();
args.putInt(KEY_POSITION, position);
frag.setArguments(args);
return(frag);
}
static String getTitle(Context ctxt, int position) {
return("PROVIDER KU");
}
#Override
public View onCreateView(LayoutInflater inflater,
ViewGroup container,
Bundle savedInstanceState) {
View result=inflater.inflate(R.layout.fragment_child_providerterdekat, container, false);
list_provider = (ListView)result.findViewById(R.id.list_provider);
list_ekamedicare = new ArrayList<ModelProviderTerdekat>();
db_esehat = new DB_Esehat(getActivity());
list_ekamedicare = db_esehat.getProvider();
adapter = new ProviderTerdekatAdapter(getActivity().getApplicationContext(), R.layout.adapter_provider, list_ekamedicare);
list_provider.setAdapter(adapter);
return result;
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
}
#Override
public void onAttach(Activity activity) {
super.onAttach(activity);
}
#Override
public void onDetach() {
super.onDetach();
}
}
and this is Adapter for my ListView
public class ProviderTerdekatAdapter extends ArrayAdapter<ModelProviderTerdekat> {
List<ModelProviderTerdekat> data = Collections.emptyList();
private LayoutInflater inflater;
private Context context;
static class ViewHolder {
ImageView imvprov_map;
ImageView imvprov_fav;
TextView textprov_nama_rs;
TextView textprov_alamat_rs;
TextView textprov_km_rs;
}
public ProviderTerdekatAdapter (Context context, int viewResourceId, List<ModelProviderTerdekat> data) {
super(context, R.layout.adapter_provider, data);
this.context = context;
inflater = LayoutInflater.from(context);
this.data = data;
}
#Override
public int getCount() {
return data.size();
}
#Override
public long getItemId(int arg0) {
return 0;
}
#Override
public View getView(int position, View view, ViewGroup parent) {
if (view == null) {
view = inflater.inflate(R.layout.adapter_provider, parent, false);
ViewHolder viewHolder = new ViewHolder();
viewHolder.imvprov_map = (ImageView) view.findViewById(R.id.imvprov_map);
viewHolder.imvprov_fav = (ImageView) view.findViewById(R.id.imvprov_fav);
viewHolder.textprov_nama_rs = (TextView) view.findViewById(R.id.textprov_nama_rs);
viewHolder.textprov_alamat_rs = (TextView) view.findViewById(R.id.textprov_alamat_rs);
viewHolder.textprov_km_rs = (TextView) view.findViewById(R.id.textprov_km_rs);
view.setTag(viewHolder);
}
ViewHolder viewHolder = (ViewHolder) view.getTag();
viewHolder.textprov_nama_rs.setText(data.get(position).getRSNAMA());
viewHolder.textprov_alamat_rs.setText(data.get(position).getRSALAMAT());
return view;
}
}
I have no Idea why my GetView() not called in my Adapter, is it because I put in ViewPager? well I hope someone understand about it and help me to solver my problem. thank you very much.
Finally.. I found a solution for my problem, it's because I put ViewPager in RelativeLayout after I change into LinearLayout all view displayed as I wanted
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v4.widget.ContentLoadingProgressBar
android:id="#+id/progressbar"
style="?android:attr/progressBarStyleLarge"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:visibility="gone"
android:indeterminate="false" />
<android.support.design.widget.TabLayout
android:id="#+id/sliding_tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabMaxWidth="0dp"
app:tabGravity="fill"
style="#style/MyCustomTabLayout"
app:tabMode="fixed"
android:fillViewport="true"
android:visibility="gone" />
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="fill_parent"
android:layout_height="0px"
android:layout_weight="1"
android:background="#android:color/white"
android:layout_below="#id/sliding_tabs"
android:visibility="gone"/>
</LinearLayout>
