I created a table view in list view adapter programmatically. For that first i created a Adapter layout as :
<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/black"
android:stretchColumns="*"
android:id="@+id/tablelayout" >
</ableLayout>
Then what I have done in the adapter is:
public class DemoAdapter extends ArrayAdapter<String> {
//Global Variable declaration
Context myContext;
String[] key, value, loop;
public DemoAdapter(Context context, String[] key, String[] value, String[] loop){
super(context, R.layout.demo_screen_adapter, loop);
this.myContext = context;
this.key = key;
this.value = value;
this.loop = loop;
}
@Override
public View getView(int position, View convertView, ViewGroup parent){
View row = convertView;
if (row == null){
// get reference to the activity
LayoutInflater inflater = ((Activity) myContext).getLayoutInflater();
// Inflate the custom text which will replace the default text view
//list_item is a simple linear layout which contain textView1 in it.
row = inflater.inflate(R.layout.demo_screen_adapter, parent, false);
}
TableLayout tableLayout = (TableLayout) row.findViewById(R.id.tablelayout);
for(int i=0; i<5; i++){
TableRow tableRow = new TableRow(myContext);
tableRow.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT, TableRow.LayoutParams.WRAP_CONTENT));
TextView tvKey = new TextView(myContext);
tvKey.setText(key[(position*5)+i]);
tvKey.setTextColor(Color.WHITE);
tvKey.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT, TableRow.LayoutParams.WRAP_CONTENT));
tableRow.addView(tvKey);
TextView tvValue = new TextView(myContext);
tvValue.setText(value[(position*5)+i]);
tvValue.setTextColor(Color.WHITE);
tvValue.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT, TableRow.LayoutParams.WRAP_CONTENT));
tableRow.addView(tvValue);
tableLayout.addView(tableRow, new TableLayout.LayoutParams(TableLayout.LayoutParams.MATCH_PARENT, TableLayout.LayoutParams.MATCH_PARENT));
}
return row;
}
}
This is working good. In my each list item there is a table view contains around two column and five rows.
Now the issue is:
I want to fetch the perticular values on click of list item. I am not able to do so.
What i tried as:
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) {
Toast.makeText(this, ""+(String) arg0.getItemAtPosition(position), Toast.LENGTH_LONG).show();
}
But it shows the position on which i click.
What should i do for that please guide me.
In your Custom Adapter.Used a holder.
This is my Custom Adapter
import java.util.ArrayList;
import com.samplelogin.CustomerDetails;
import com.samplelogin.R;
import android.app.Activity;
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.ArrayAdapter;
import android.widget.Button;
import android.widget.TextView;
public class UserCustomAdapter extends ArrayAdapter<Customers> {
Context context;
int layoutResourceId;
ArrayList<Customers> data = new ArrayList<Customers>();
public UserCustomAdapter(Context context, int layoutResourceId,
ArrayList<Customers> data) {
super(context, layoutResourceId, data);
this.layoutResourceId = layoutResourceId;
this.context = context;
this.data = data;
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
View row = convertView;
UserHolder holder = null;
if (row == null) {
LayoutInflater inflater = ((Activity) context).getLayoutInflater();
row = inflater.inflate(layoutResourceId, parent, false);
holder = new UserHolder();
holder.textName = (TextView) row.findViewById(R.id.textView1);
holder.textAddress = (TextView) row.findViewById(R.id.textView2);
holder.textLocation = (TextView) row.findViewById(R.id.textView3);
holder.btnEdit = (Button) row.findViewById(R.id.button1);
row.setTag(holder);
} else {
holder = (UserHolder) row.getTag();
}
Customers user = data.get(position);
holder.textName.setText(user.getName());
holder.textAddress.setText(user.getAddress());
holder.textLocation.setText("");
holder.btnEdit.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Customers user = data.get(position);
user.setTID(user.getID());
user.setTName(user.getName());
user.setTAddress(user.getAddress());
user.setTTelNo(user.getTelNo());
user.setTMobileNo(user.getMobileNo());
user.setTFaxNo(user.getFaxNo());
Intent intent = new Intent(context, CustomerDetails.class);
context.startActivity(intent);
}
});
return row;
}
static class UserHolder {
TextView textName;
TextView textAddress;
TextView textLocation;
Button btnEdit;
Button btnDelete;
}
}
And in my activity. I put data on it by:
declare you variable
// Customer
ListView CustomerList;
UserCustomAdapter CustomerAdapter;
ArrayList<Customers> CustomerArray = new ArrayList<Customers>();
Button addCustomer;
Put fill up your value with a data.
// Customer Tab
cdb = new CustomerDB(getApplicationContext());
int custcount = cdb.getCustomerCount();
if (custcount > 0) {
List<Customers> cdbL = cdb.getAllCustomers();
int listSize = cdbL.size();
for (int i = 0; i < listSize; i++) {
CustomerArray.add(new Customers(cdbL.get(i).getDBName()
.toString(), cdbL.get(i).getDBAddress().toString(),
cdbL.get(i).getDBTelNo().toString(), cdbL.get(i)
.getDBMobileNo().toString(), cdbL.get(i)
.getDBFaxNo().toString(), cdbL.get(i).getDBID()
.toString()));
}
}
Now, from your list. transfer you data to your custom adapter
// set item into adapter
CustomerAdapter = new UserCustomAdapter(MainMaintenance.this,
R.layout.maintenancetab, CustomerArray);
CustomerList = (ListView) findViewById(R.id.lvCustomer);
CustomerList.setItemsCanFocus(false);
CustomerList.setAdapter(CustomerAdapter);
Here, you can click the item and do what you want. in this sample, i pass my data in a list in a public class and then i go to the next activity.
// get on item click listener
CustomerList.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
Customers user = CustomerArray.get(arg2);
user.setTID(user.getID());
user.setTName(user.getName());
user.setTAddress(user.getAddress());
user.setTTelNo(user.getTelNo());
user.setTMobileNo(user.getMobileNo());
user.setTFaxNo(user.getFaxNo());
Intent intent = new Intent(MainMaintenance.this,
CustomerDetails.class);
startActivity(intent);
}
});
The setOnClickListener in your custom adapter is if you will put a button in you custom adapter :) if youll be confuse just tell me :)
I hope that this sample code will give you an idea and help you.
