My Problem was solved, anyway thank you for all.
I need to edit getView() Method inside the EfficientAdapter class
public View getView(final int position, View convertView, ViewGroup
parent) {
ViewHolder holder;
if(convertView == null){
convertView = mInflater.inflate(R.layout.jobboards, null);
holder = new ViewHolder();
holder.textLine = (TextView)
convertView.findViewById(R.id.textLine);
holder.buttonLine =(Button)
convertView.findViewById(R.id.buttonLine);
convertView.setTag(holder);
}
holder =(ViewHolder) convertView.getTag();
holder.textLine.setText((String)getItem(position));
convertView.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
//startActivity(new Intent(EfficientAdapter.class,
JobboardHeadLines.class).addFlags(Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT));
callJobboardHeadLinesActivity(String.valueOf(position),v,data.get(position).toString().toUpperCase().trim());
Toast.makeText(context, "Click-" +
String.valueOf(position), Toast.LENGTH_SHORT).show();
}
});
holder.buttonLine.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
data.remove(position);
notifyDataSetChanged();
Log.i(TAG, "Delete button pressed at position" +
position);
Toast.makeText(context, "Delete-" +
String.valueOf(position), Toast.LENGTH_SHORT).show();
}
});
return convertView;
}
