Buttons in custom dialogs | Android
Paramount
After I click the "SMS" button, I get a popup dialog.
The SMS button only works if the length of the text field is greater than 0. (non empty...)
This is how the "SMS" button calls onClick.
private void smsPopUp() {
// TODO Auto-generated method stub
final Dialog smsDialog = new Dialog(this);
Button cancelsms = (Button)smsDialog.findViewById(R.id.smsCancel);
smsDialog.setContentView(R.layout.sms_dialog);
smsDialog.setTitle("To: " + numberfield.getText());
cancelsms.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v)
{
smsDialog.dismiss();
}
});
smsDialog.show();
}
If I comment out the onClick inside the method, the dialog pops up with two buttons: "Cancel" and "Send". Basically, it works without the buttons working. if i run this code...i get error..

I've thought about making an "alert dialog", which is obviously easier. But I'm not sure if it's possible to create a custom onClick for the "positive button". Because there will be a lot of code on "send" onClick

(Only show the top in the dialog (textbox + 2 buttons) as needed.)

Reverse the following statement
Button cancel = (Button)smsDialog.findViewById(R.id.smsCancel);
smsDialog.setContentView(R.layout.sms_dialog);
should
smsDialog.setContentView(R.layout.sms_dialog);
Button cancel = (Button)smsDialog.findViewById(R.id.smsCancel);
You need to send the layout to the dialog first and then initialize the view.
