How can I save the input data into database using sqlitebrowse?

Sorry for my lame question, but I'm still a beginner in android programming. Here my code for the Activity/Java Im also using intent in this program

public class DrinkActivity extends Activity {

EditText inputdrink;
Button btnNextScreen1;

protected void onCreate (Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_drink);

inputdrink = (EditText) findViewById(R.id.txtdrink);
btnNextScreen1 = (Button) findViewById(R.id.btnnext1);
btnNextScreen1.setOnClickListener(new View.OnClickListener() {

public void onClick(View v) {
Intent nextScreen = new Intent    (DrinkActivity.this,DessertActivity.class);

nextScreen.putExtra("drink", inputdrink.getText().toString());
Log.e("n", inputdrink.getText()+".");
startActivity(nextScreen);
}
});
}
}

This is my second

public class DessertActivity extends Activity {

EditText inputdessert;
Button btnNextScreen2;

protected void onCreate (Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_dessert);

    inputdessert = (EditText) findViewById(R.id.txtdessert);
    btnNextScreen2 = (Button) findViewById(R.id.btnnext2);
    btnNextScreen2.setOnClickListener(new View.OnClickListener() {

    public void onClick(View v) {
        Intent i = getIntent();
        String a = i.getStringExtra("drink");
        Intent nextScreen = new Intent (DessertActivity.this, MaindActivity.class);

        nextScreen.putExtra("dessert", inputdessert.getText().toString());
        nextScreen.putExtra("drnk", a.toString());
        Log.e("n", inputdessert.getText()+".");

        startActivity(nextScreen);
}
});
}
}

This is my third

public class MaindActivity extends Activity {

EditText inputmaind;
Button btnNextScreen3;



protected void onCreate (Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maind);

inputmaind = (EditText) findViewById(R.id.txtmaind);
btnNextScreen3 = (Button) findViewById(R.id.btnnext3);
btnNextScreen3.setOnClickListener(new View.OnClickListener() {

public void onClick(View v) {
    Intent i = getIntent();
    String b = i.getStringExtra("drnk");
    String c = i.getStringExtra("dessert");
Intent nextScreen = new Intent ( MaindActivity.this,SummaryActivity.class);

nextScreen.putExtra("drinks", b.toString());
nextScreen.putExtra("desserts", c.toString());

nextScreen.putExtra("maind", inputmaind.getText().toString());
Log.e("n", inputmaind.getText()+".");
startActivity(nextScreen);
}
});
}
}

This is the last Activity

public class SummaryActivity extends Activity {

public void onCreate (Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_summary);

TextView txtDrinks = (TextView) findViewById(R.id.dspDrink);
TextView txtDessert = (TextView)findViewById(R.id.dspDessert);
TextView txtMainD = (TextView) findViewById(R.id.dspMaind); 
Button btnClose = (Button) findViewById(R.id.btnclose);

    Intent i = getIntent ();

    String drink = i.getStringExtra("drinks");
    String dessert = i.getStringExtra("desserts");
    String maind = i.getStringExtra("maind");

    Log.e("n", drink + "." + dessert + "." + maind + ".");

    txtDrinks.setText(drink);
    txtDessert.setText(dessert);
    txtMainD.setText(maind);

    btnClose.setOnClickListener(new View.OnClickListener() {

public void onClick(View v) {
finish();
}
});
}
}
