[android-developers] Dynamic ArrayAdapter and Spinner
Hi all I need to create an ArrayAdapter and a Spinner that are totally dynamic and have nothing to do with the layout file. So I am trying to do something like: Spinner spinnerListID; spinnerListID = new Spinner (this); String[] array_spinner = new String[5]; array_spinner[0]="1"; array_spinner[1]="2"; array_spinner[2]="3"; array_spinner[3]="4"; array_spinner[4]="5"; ArrayAdapter adapter = new ArrayAdapter(this, ?, array_spinner); spinnerListID.setAdapter(adapter); ll.addView(editTextInputListID); But I can not see how I can create an ArrayAdapter that does not need a textViewResourceId? As it is described http://developer.android.com/reference/android/widget/ArrayAdapter.html: It looks like it is a needed constructor parameter. Or should I not use this way at all?

Re: [android-developers] Dynamic Buttons Onclick
Thanks Kostya,
Does anyone also happen to know how can we make a button that has been
created dynamically
set to "wrap_content" (as we do in the static mode) to make the
*button fit* neatly
around the text?
Thank you,
Sara

[android-developers] Dynamic Buttons Onclick
Hi.
I have some dynamic buttons that are being generated inside a for loop.
for (int i = 0; i < 5 ; i++) {
> Button aUIXButton = new Button (SecondPage.this);
aUIXButton.setClickable(true);
aUIXButton.setText("X");
> aUIXButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
aUIXButton.setText("Y");
}});
}
This is not working. It says
"Cannot refer to a non-final variable aUIXButton inside an inner class
defined in a different method"
& wants to change the modifier of aUIXButton to final & I don't want to do
that.
Does anyone know how can I fix this?
Thank you,

[android-developers] Add CheckBox on buttonclick - Dynamic Mode
Hi all
I am trying to run the attached code to display a checkbox when I click on
the buttons.
My program crashes though and I can not see why.
Do you have any idea?
Thank you,
Sara
package Dynamiclayout.example.com;
import Dynamiclayout.example.com.R;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.ScrollView;
import android.widget.LinearLayout;
import android.widget.Button;
import android.widget.CheckBox;
public class Dynamiclayout extends Activity {
ButtonbuttonGET,buttonPost;
CheckBox checkbox1;
LinearLayout ll = null;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
class clicker implements Button.OnClickListener {
@Override
public void onClick(View v) {
if(v==buttonGET){
checkbox1 = new CheckBox (null);
checkbox1.setText("I'm dynamic!");
ll.addView(checkbox1);
}
if(v==buttonPost){
checkbox1.setText("I'm very dynamic!");
ll.addView(checkbox1);
}
}
}
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ScrollView sv = new ScrollView(this);
//LinearLayout ll = new LinearLayout(this);
ll = new LinearLayout(this);
ll.setOrientation(LinearLayout.VERTICAL);
sv.addView(ll);

buttonGET.setText("GET");
ll.addView(buttonGET);
buttonGET.setOnClickListener(new clicker());
buttonPost = new Button(this);
buttonPost.setText("POST");
ll.addView(buttonPost);
buttonPost.setOnClickListener(new clicker());
this.setContentView(sv);
}

[android-developers] How to use the httpdelete on a list?
Hi all,
Say the server is providing you with an xml list which looks like
this:
0
-
1
Unknown owner
Randomly generated list
-
-
1
Bananas
open
-
2
Bread
open
-
3
Süssmost
open
How can you write a httpdelete request that would delete the "Bread"?
So that when you GET
NodeList items = doc.getElementsByTagName("name");
You see only
Banana and Süssmost.
Thank you,
Sara
