EditText input saved in Database

I'm really new to Android and i'd like to save the Input of my Edittext into my Database. Here's my Database:

Its a Copy of an Other Database i change to work on my own.

Heres my layout.xml:

                 </TableRow>
    </TableLayout>

And heres my Activity:

package de.retowaelchli.filterit;

import android.app.Activity;
import android.os.Bundle;


public class ADFilterConfigActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.autodelete_config);


    }
}

What do i have to do that it saves my Input text into my Database. Thx in advance.

 1. In activity's OnCreate() define your editText views from xml file.
    edtTextName = (EditText) findViewById(R.id.ADConfigName);
    edtTextKeyword = (EditText) findViewById(R.id.ADConfigKeyword);


 2. get string from editText views . 
     likes, 
           String name = edtTextName.getText().toString();
           String keyword = edtTextKeyword.getText().toString();


 3. then using these values call your database's insert method. I think its  
     createADFilter( name,keyword,cache)

so, simple. :-)

I write this procedure bcoz i want, do coding by yourself with this procedure, then in actually you can know how to connect with database in sqlite. avoid copy paste. Thnx.
