Hi Treking,
I have tried as you have suggested but not able to get the value.
May be i missing something.
Here is my code:
public class GetDialog extends Activity
{
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button valueButton = (Button) findViewById(R.id.viewButton);
valueButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
showDialog(0);
}
});
}
protected Dialog onCreateDialog(int id) {
LayoutInflater factory = LayoutInflater.from(this);
final View textEntryView = factory.inflate
(R.layout.viewlayout, null);
return new AlertDialog.Builder(this)
.setIcon(R.drawable.view)
.setTitle("Enter Value")
.setView(textEntryView)
.setPositiveButton("OK", new
DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int
whichButton) {
EditText valueText = (EditText) findViewById
(R.id.viewText);
getvalue(valueText );
}
})
.setNegativeButton("Cancel", new
DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int
whichButton) {
}
})
.create();
}
void getvalue(EditText val)
{
try{
String value= val.getText().toString();
Log.i("Value ",value);
}catch(Exception e){
Log.i("Error", e.toString() );
}
}
}
It gives me error as: Java.lang.NullPointerException
please suggest.
Thanks
