Which ones should I use on Android instead of normal Java
Question
I'm new to Android programming; I made couple programs about simple table which is just works for "Getting data from database and show it on table" or "Save the texts which is in jtextfields to database". So I need to do this on Android but I think my knowledge doesn't work at all on Android. How should I do this on Android?

Android equivilent of JPanel is LinearLayout
equivilent of JButton is Button
JLabel -> TextView
JScrollPane -> ScrollView
JOptionPane -> AlertDialog or Spinner or Dialog depending on what your app does
equivilent of ResultSet is Cursor -- used exactly the same as ResultSet
example:
Cursor c = database.query("SELECT * FROM someTable");
int someValue = c.getInt(someTableColumnIndex);
String someStringValue = c.getString(someTableOtherColumnIndex);
lookup: http://developer.android.com/reference/android/database/sqlite/SQLiteDatabase.html
but your code needs major rewrites to make it look the same on Android
Android mostly uses XML layouts, but you can use code to create your layout
example :
public class MainActivity extends Activity{
@Override
public void onCreate(Bundle savedInstanceState){
LinearLayout layout = new LinearLayout(this,new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT); //width and height
Button button = new Button(this);
button.setText("hello");
button.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v){
Toast.makeText(MainActivity.this,"you clicked me! my text is: "+(Button)v.getText().toString(),Toast.LENGTH_LONG).show();
}
});
}
}
If you want to build a table - Android has TableLayout look this up: http://developer.android.com/reference/android/widget/TableLayout.html
