import java.util.ArrayList;
public class Tutorial{
Context c;
ListView listView;
Activity a;
TutorialAdapter chettingAdapter;
TextView CNoData;
public Tutorial(Context c, ListView listView, Activity a, TextView CNoData) {
this.c = c;
this.listView = listView;
this.a = a;
this.CNoData = CNoData;
}
public void getUpdate(ArrayList<TutorialData> chettingDatas)
{
if(chettingDatas.size()>0)
{
CNoData.setVisibility(View.GONE);
listView.setVisibility(View.VISIBLE);
chettingAdapter = new TutorialAdapter(c,a,chettingDatas);
listView.setAdapter((ListAdapter)chettingAdapter);
}
else
{
CNoData.setVisibility(View.VISIBLE);
CNoData.setText("No Data");
listView.setVisibility(View.GONE);
}
}
}
</per>
2) TutorialAdapter File Paste the Below Code
<pre>
import android.app.Activity;
import android.content.Context;

import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.Toast;
import java.util.ArrayList;
public class TutorialAdapter extends BaseAdapter {
Context c;
Activity a;
ArrayList<TutorialData> chettingDatas;
LayoutInflater layoutInflater;
public TutorialAdapter(Context c, Activity a, ArrayList<TutorialData> chettingDatas) {
this.c = c;
this.a = a;
this.chettingDatas = chettingDatas;
}
@Override
public int getCount() {
return chettingDatas.size();
}
@Override
public Object getItem(int position) {
return chettingDatas.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
if (layoutInflater == null) {
layoutInflater = (LayoutInflater)c.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
if (convertView == null)
{
convertView= layoutInflater.inflate(R.layout.layout_tutorial,parent,false);
}
TutorialHolder Holder = new TutorialHolder(convertView);
Holder.b1.setText(chettingDatas.get(position).getData());
Holder.b1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(c, "Clicked : "+chettingDatas.get(position).getData(), Toast.LENGTH_SHORT).show();
}
});
return convertView;
}
}
3) TutorialData File Paste the Below Code
public class TutorialData {
private String data;
public String getData() {
return data;
}
public void setData(String data) {
this.data = data;
}
}
4) TutorialHolder File Paste the Below Code
public class TutorialHolder {
Button b1;
TutorialHolder(View v)
{
b1 = (Button)v.findViewById(R.id.b1);
}
}
Then the Last Code is MainActivity.java paste the below code
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ListView listview = (ListView)findViewById(R.id.listview);
TextView NoData = (TextView)findViewById(R.id.NoData);
ArrayList<TutorialData> chettingDatas= new ArrayList<>();
TutorialData T = new TutorialData();
T.setData("Hello");
chettingDatas.add(T);
TutorialData T1 = new TutorialData();
T1.setData("Bro");
chettingDatas.add(T1);
TutorialData T2 = new TutorialData();
T2.setData("Hi");
chettingDatas.add(T2);
TutorialData T3 = new TutorialData();
T3.setData("Buy");
chettingDatas.add(T3);
Tutorial Tu = new Tutorial(MainActivity.this,listview,MainActivity.this,NoData);
Tu.getUpdate(chettingDatas);
}
}
