I don't know why but my Custom List view is not working . When I call ListView.setadapter , my adapter don't call getView() method . I figured this problem about 2 day straight But I don't know why . No Error No working . Help me Pls . This is serious
This is my Custom Adapter Code :
import java.util.ArrayList;
import android.app.Activity;
import android.content.Context;
import android.content.res.Resources;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageButton;
import android.widget.ImageView;
import android.widget.TableRow;
import android.widget.TextView;
public class CustomAdapter extends BaseAdapter{
private Activity activity;//for parameter
private ArrayList data;//for parameter
public Resources res;//for parameter
private static LayoutInflater inflater=null;
ListModel getList ;
int i=0;
public CustomAdapter(Activity a, ArrayList data,Resources resLocal) {
activity = a;
this.data=data;
res = resLocal;
/*********** Layout inflator to call external xml layout () **********************/
inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
@Override
public int getCount() {
if (data.size()<=0)
return 1;
return 0;
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
public static class ViewHolder{
public ImageView image;
public TextView txt_memberName;
public TextView txt_memberStatus;
public ImageButton imgbtn_senka;
public ImageButton imgbtn_fuenka;
public TableRow tblrow_status;
public TableRow tblrow_btn;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
ViewHolder holder = new ViewHolder();;
View vi=convertView;
Log.i("tag", "INVIEW");
holder.txt_memberName=(TextView)vi.findViewById(R.id.txtmemberName);
holder.txt_memberStatus=(TextView)vi.findViewById(R.id.txtmemberStatus);
holder.image=(ImageView)vi.findViewById(R.id.imgPlayer);
holder.imgbtn_fuenka = (ImageButton) vi.findViewById(R.id.btnfusenka);
holder.imgbtn_senka = (ImageButton) vi.findViewById(R.id.btnsenka);
holder.tblrow_status = (TableRow)vi.findViewById(R.id.tblrowstatus);
holder.tblrow_status = (TableRow)vi.findViewById(R.id.tblrowbtn);
if(convertView==null){
/********** Inflate tabitem.xml file for each row ( Defined below ) ************/
vi = inflater.inflate(R.layout.tabitem, null);
holder.txt_memberName=(TextView)vi.findViewById(R.id.txtmemberName);
holder.txt_memberStatus=(TextView)vi.findViewById(R.id.txtmemberStatus);
holder.image=(ImageView)vi.findViewById(R.id.imgPlayer);
holder.imgbtn_fuenka = (ImageButton) vi.findViewById(R.id.btnfusenka);
holder.imgbtn_senka = (ImageButton) vi.findViewById(R.id.btnsenka);
holder.tblrow_status = (TableRow)vi.findViewById(R.id.tblrowstatus);
holder.tblrow_status = (TableRow)vi.findViewById(R.id.tblrowbtn);
/************ Set holder with LayoutInflater ************/
vi.setTag(holder);
}
else
holder=(ViewHolder)vi.getTag();
if(data.size()<=0)
{
Log.i("Tag", "No Data");
}
else
{
/***** Get each Model object from Arraylist ********/
getList=null;
getList = (ListModel) data.get(position);
if(getList.getMemberStatus()==2){
Log.i("null", "2");
//holder.tblrow_btn.setVisibility(View.GONE);
}
/************ Set Model values in Holder elements ***********/
holder.txt_memberName.setText(getList.getMemberName());
holder.txt_memberStatus.setText(getList.getImage());
holder.image.setImageResource(res.getIdentifier("com.androidexample.customlistview:drawable/"+getList.getImage(),null,null));
holder.txt_memberName.setText(getList.getMemberName());
holder.image.setImageResource(res.getIdentifier("com.androidexample.customlistview:drawable/"+getList.getImage(),null,null));
}
return vi;
}
}
This is where I call Custom Adapter Object :
import java.util.ArrayList;
import org.apache.http.NameValuePair;
import org.apache.http.message.BasicNameValuePair;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
import android.os.Bundle;
import android.os.StrictMode;
import android.app.Activity;
import android.content.Intent;
import android.content.res.Resources;
import android.util.Log;
import android.view.Menu;
import android.widget.ListView;
import android.widget.TextView;
public class MainActivity extends Activity {
ListView list;
JSONObject Jobj;
TextView txt_Date;
TextView txt_Location;
String team_ID;
CustomAdapter custAdpt;
public MainActivity main = null;
ListModel model = new ListModel();
public ArrayList<ListModel> ListModelArr = new ArrayList<ListModel>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_custom_list_view_android_example);
txt_Date = (TextView) findViewById(R.id.txt_date);
txt_Location = (TextView) findViewById(R.id.txt_location);
Intent intent = getIntent();
txt_Date.setText(intent.getStringExtra("startTime"));
txt_Location.setText(intent.getStringExtra("location"));
team_ID = intent.getStringExtra("teamID");
setListData();
Resources res =getResources();
list=(ListView)findViewById(R.id.participationList);
MainActivity main = this;
custAdpt = new CustomAdapter(main, ListModelArr, res);
list.setAdapter(custAdpt);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
public void setListData(){
StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()
.detectDiskReads().detectDiskWrites().detectNetwork()
.penaltyLog().build());
String response = null; // to accept Json String from php
String memberName = null; // for member name to display in list
String photo = null ; // for photo path
int memberStatus = 0; // to check member status
JSONArray memberData=null; // to retrieve member data from json response
ArrayList<NameValuePair> postParameters = new ArrayList<NameValuePair>();
postParameters.add(new BasicNameValuePair("teamID",team_ID));
postParameters.add(new BasicNameValuePair("startTime","2013-09-18 10:00:00"));// parameter for php
try {
response = CustomHttpClient.executeHttpPost(
"http://10.0.2.2/football365/sankashaList.php",
postParameters);
Jobj = new JSONObject(response);
memberData=Jobj.getJSONArray("memberdata");
for(int i = 0 ; i < memberData.length(); i++){
memberName = (memberData.getJSONObject(i).getString("name").toString());
memberStatus = Integer.parseInt((memberData.getJSONObject(i).getString("memberStatus").toString()));
photo = (memberData.getJSONObject(i).getString("photo").toString());
model.setMemberName(memberName);
model.setMemberStatus(memberStatus);
model.setImage(photo);
ListModelArr.add(model);
}
}
catch(JSONException e){
Log.e("log_tag", "Error parsing data "+e.toString());
}
catch (Exception e) {
Log.e("log_tag", "Error parsing data "+e.toString());
}
}
}
This is where I define Getter & Setter Methods
public class ListModel {
private String imgMember;
private String memberName;
private int memberStatus;
///Setters
public void setMemberName(String memberName)
{
this.memberName = memberName;
}
public void setImage(String imgMember)
{
this.imgMember = imgMember;
}
public void setMemberStatus(int memberStatus)
{
this.memberStatus=memberStatus;
}
///Getters
public String getMemberName()
{
return this.memberName;
}
public String getImage()
{
return this.imgMember;
}
public int getMemberStatus()
{
return this.memberStatus;
}
}
Change
@Override
public int getCount() {
if (data.size()<=0)
return 1;
return 0;
}
to
@Override
public int getCount() {
if (data.size()<=0)
return 1;
return data.size();
}
