setListAdapter() Gone Wrong

When I try to use setListAdapter to show my data this happens:
Cannot resolve method setListAdapter
This is my Activity:
package id.sch.smktelkom.www.crud;
import android.app.ProgressDialog;
import android.content.Intent;
import android.database.Cursor;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.ListView;
import android.widget.Toast;
import java.util.List;
public class CollectionActivity extends AppCompatActivity implements
FetchCollectListener {
String[] daftar;
ListView listView;
protected Cursor cursor;
Button search;
private ProgressDialog dialog;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_collection);
Button btn=(Button)findViewById(R.id.button2);
search = (Button) findViewById(R.id.cari);
initView();
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Intent inte = new Intent(CollectionActivity.this, MainActivity.class);
startActivity(inte);
}
});
search.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent c = new Intent(CollectionActivity.this, SearchV.class);
startActivity(c);
}
});
}
private void initView() {
// show progress dialog
dialog = ProgressDialog.show(CollectionActivity.this, "", "Loading...");
String url = "http://192.168.4.5/SqliteSync/readC.php";
FetchCollection task = new FetchCollection(this);
task.execute(url);
}
#Override
public void onFetchComplete(List<Collect> data) {
// dismiss the progress dialog
if(dialog != null) dialog.dismiss();
// create new adapter
CollectAdapter adapter = new CollectAdapter(this, data);
// set the adapter to list
setListAdapter(adapter);
}
#Override
public void onFetchFailure(String msg) {
// dismiss the progress dialog
if(dialog != null) dialog.dismiss();
// show failure message
Toast.makeText(this, msg, Toast.LENGTH_LONG).show();
}
}
And this is my Adapter:
package id.sch.smktelkom.www.crud;
import android.content.Context;
import android.content.Intent;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageButton;
import android.widget.TextView;
import java.util.List;
public class CollectAdapter extends ArrayAdapter<Collect> {
private List<Collect> items;
private Context mContext;
public CollectAdapter(Context context, List<Collect> items) {
super(context, R.layout.item_collect, items);
this.items = items;
mContext = context;
}
#Override
public int getCount() {
return items.size();
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if(v == null) {
LayoutInflater li = LayoutInflater.from(getContext());
v = li.inflate(R.layout.item_collect, null);
}
Collect app = items.get(position);
if(app != null) {
TextView id = (TextView) v.findViewById(R.id.txtpeminjam);
TextView name = (TextView) v.findViewById(R.id.txtpinjaman);
ImageButton btn = (ImageButton) v.findViewById(R.id.list_image);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent b = new Intent(mContext,LihatDataActivity.class);
mContext.startActivity(b);
}
});
if(id != null) id.setText(app.getNama());
if(name != null) name.setText(app.getPinjaman());
}
return v;
}
}
I don't know what's wrong with this and it's annoying me already.
I want to retrieve data from MySQL to my Android app and when I type setListAdapter suddenly it becomes red and shows some error.
Appreciate any help.

Instead of setListAdapter(adapter); call listView.setAdapter(adapter);
setListAdapter works for activities extending ListActivity
I see also that you should add in onCreate this:
ListView listView=(ListView)findViewById(R.id.listView);
if the name of the ListView is listView in xml

So after some advice from #AmitVikramSingh
I'm referencing my listview
public class CollectionActivity extends AppCompatActivity implements FetchCollectListener {
String[] daftar;
ListView listView;
protected Cursor cursor;
Button search;
private ProgressDialog dialog;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_collection);
Button btn=(Button)findViewById(R.id.button2);
search = (Button) findViewById(R.id.cari);
listView = findViewById(R.id.list);
And I change this from
#Override
public void onFetchComplete(List<Collect> data) {
// dismiss the progress dialog
if(dialog != null) dialog.dismiss();
// create new adapter
CollectAdapter adapter = new CollectAdapter(this, data);
// set the adapter to list
setListAdapter(adapter);
}
To this
#Override
public void onFetchComplete(List<Collect> data) {
// dismiss the progress dialog
if(dialog != null) dialog.dismiss();
// create new adapter
CollectAdapter adapter = new CollectAdapter(this, data);
// set the adapter to list
listView.setAdapter(adapter);
}
Big thanks to all who help me solving this problem

your code is ok you need to add a listener in your adapter for the view on which you want to fire an intent for example
inside your adapter getview method paste this code like this
#Override
public View getView(int position, View convertView, ViewGroup parent) {
Tipster_list services=tipslist.get(position);
if(services!=null){
LayoutInflater inflater=(LayoutInflater) context.getSystemService(context.LAYOUT_INFLATER_SERVICE);
convertView=inflater.inflate(R.layout.activity_custom_adapter,null);
ImageView icon=(ImageView)convertView.findViewById(R.id.icon_tipsterIconID);
TextView name=(TextView) convertView.findViewById(R.id.txt_name_tipsterID);
TextView total=(TextView) convertView.findViewById(R.id.txt_total_tipsterID);
TextView proofingLink=(TextView) convertView.findViewById(R.id.txt_proofinglink_tipsterID);
TextView siteLink=(TextView) convertView.findViewById(R.id.txt_sitelink_tipsterID);
Picasso.with(context).load(services.getImage()).into(icon);
Log.d("Url",services.getImage());
name.setText(services.getName());
total.setText(services.getTotal());
proofingLink.setText(services.getProofinglink());
siteLink.setText(services.getSitelink());
convertView.setTag(position);
String getName=services.getName();
final String getproofing=services.getProofinglink();
final String getsite=services.getSitelink();
proofingLink.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent(context, Tipster_webview.class);
intent.putExtra("gettproofing_URl",getproofing);
context.startActivity(intent);
}
});
siteLink.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent(context, Tipster_webview.class);
intent.putExtra("site",getsite);
context.startActivity(intent);
}
});
}
return convertView;
}

TextView proofingLink=(TextView) convertView.findViewById(R.id.txt_proofinglink_tipsterID);
proofingLink.setOnClickListener(new OnItemClickListener() {
#Override
public void onClick(View arg0) {
String url = services.getProofinglink();
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);
}
});

TextView proofingLink=(TextView)
convertView.findViewById(R.id.txt_proofinglink_tipsterID);
proofingLink.setOnClickListener(new OnClickListener() {
#Override

Where the custome class is extends from base adapter in order to have list view with image view set to video image and text view set to video title.
In log cat messages the result are existed but my list view returns empty.
Can any one tell me why?
here is the code for costume list view:
public class custome extends BaseAdapter {
ArrayList<videos> data=new ArrayList<videos>();
android.content.Context context1;
android.widget.TextView name;
ImageView picture;
public custome(Context context,ArrayList<videos>arrayList) {
// TODO Auto-generated constructor stub
context=context;
arrayList=data;
}
public int getCount() {
// TODO Auto-generated method stub
return data.size();
}
public Object getItem(int arg0) {
// TODO Auto-generated method stub
return data.get(arg0);
}
public long getItemId(int arg0) {
// TODO Auto-generated method stub
return arg0;
}
public View getView(int arg0, View arg1, ViewGroup arg2) {
View view=arg1;
if(view==null)
{
LayoutInflater layoutInflater=(LayoutInflater) _c.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view=layoutInflater.inflate(R.layout.listvideo,null);
}
name=(TextView) view.findViewById(R.id.textView1);
picture=(ImageView) view.findViewById(R.id.imageView1);
videos video = data.get(arg0);
name.setText(video.getVideoname());
URL url = null;
try {
url = new URL(video.getImageurl());
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Bitmap bitmap = null;
try {
bitmap = BitmapFactory.decodeStream(url.openConnection().getInputStream());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
picture.setImageBitmap(bitmap);
return view;
}
}

The problem is in your assigning code of custome constructor:
Use this constructor:
public custome(Context context,ArrayList<videos> arrayList) {
context=context;
//arrayList=data;<<< WRONG
data=arrayList;//<<<<<<< Correct way of assigning
}

You are overriding your adapter here:
listview.setAdapter(new custome(MainActivity.this,videolist));
Remove this line

Calling activitygroup from customlistadapter

I am working on an android app which is having functionality of tabs.
Everything is working fine but I am not able to call activtygroup from listadapter.
Here is my code for list adapter:
import java.util.ArrayList;
import android.app.Activity;
import android.app.ActivityGroup;
import android.content.Context;
import android.content.Intent;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.TextView;
import com.tv.socialgoal.R;
import com.tv.socialgoal.imageloader.ImageLoader;
public class AllyListAdapter extends BaseAdapter{
Activity ctx;
ArrayList<Object> alist;
private ImageLoader imageLoader;
AllyBean allyBean;
private String photoPath;
public AllyListAdapter(Activity ctx, ArrayList<Object> alist) {
super();
this.ctx = ctx;
this.alist = alist;
imageLoader=new ImageLoader(ctx);
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return alist.size();
}
#Override
public Object getItem(int arg0) {
// TODO Auto-generated method stub
return null;
}
#Override
public long getItemId(int arg0) {
// TODO Auto-generated method stub
return 0;
}
#Override
public View getView(int position, View arg1, ViewGroup arg2) {
LayoutInflater linf=(LayoutInflater) ctx.getSystemService(ctx.LAYOUT_INFLATER_SERVICE);
View v=linf.inflate(R.layout.ally_list_row, null);
TextView tv=(TextView)v.findViewById(R.id.allyName);
ImageView profileImage=(ImageView)v.findViewById(R.id.ally_image);
Button inviteBtn=(Button)v.findViewById(R.id.invite_btn);
//SHOW DATA FROM LIST
allyBean=(AllyBean)alist.get(position);
tv.setText(allyBean.getName());
photoPath=allyBean.getAvatar();
profileImage.setTag(photoPath);
imageLoader.displayImage(photoPath, ctx, profileImage, false);
inviteBtn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Intent intent=new Intent(ctx,AddRemoveFriendScreen.class);
//intent.putExtra("friendId", allyBean.getUserId());
ctx.startActivity(intent);
}
});
return v;
}
/*public void replaceContentView(String id, Intent newIntent) {
View view =getLocalActivityManager().startActivity(id,
newIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP))
.getDecorView();
this.setContentView(view);
}*/
}
Now I have to call AddRemoveFriends activtygroup.
Here is the code for activtygroup:

}

break;
}
}
private Handler _handler = new Handler() {
public void dispatchMessage(Message msg) {
switch (msg.arg1) {
case Constant.PID_ADD_REMOVE_FRIEND:
if (parseResponse(msg.obj.toString()) == true) {

}
break;

}
}
};
// GET USER ACCESSTOCKEN AND USER ID
private boolean parseResponse(String response) {
String message = null;
JSONObject post;
boolean isUserInfoAvail = false;
try {
JSONObject postjsonObject = new JSONObject(response);
JSONObject posts = postjsonObject.getJSONObject("posts");
post = posts.getJSONObject("post");
message = post.getString("message");
if (message.equalsIgnoreCase("failure")) {
isUserInfoAvail = false;
} else {

}
} catch (JSONException e1) {

// CALL WEBSERVICE

} else {

}
// SERVER RESPONSE METHOD
public void serverResponse(String response, int processid) {
Message msg = new Message();
msg.arg1 = processid;

_handler.dispatchMessage(msg);
}
}
Please suggest me how to call activtygroup from listadapter.

Make it like this you can access everything by doing like this.
public class AddRemoveFriendScreen extends ActivityGroup implements OnClickListener, IServerResponse
{
#Override
protected void onCreate(Bundle savedInstanceState)
{
.......
}
class AllyListAdapter extends BaseAdapter
{
//Now you can call everything from ActivityGroup
}
}
Hope this will help you.

According to the android developper reference, you may use Fragments.
ActivityGroup is deprecated. Use the new Fragment and FragmentManager APIs instead; these are also available on older platforms through the Android compatibility package.
You can try this trick.
inviteBtn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
if(ctx instanceof ActivityGroup){
Intent intent = new Intent(ctx.getParent(),AddRemoveFriendScreen.class);
//intent.putExtra("friendId", allyBean.getUserId());
ctx.getParent().startActivity(intent);
}
else{
Intent intent = new Intent(ctx,AddRemoveFriendScreen.class);
//intent.putExtra("friendId", allyBean.getUserId());
ctx.startActivity(intent);
}
}
});
If it doesn't work just use internal class for your adapter in your AddRemoveFriendScreen class.
