I created one alert dialog box, it’s working fine for me. Now i am expect to create if i press f2 button in softkeyboard i wish to show alertbox that’s all. I tried but its not working. Sample code please.
my coding:
public class HelloList extends Activity
{
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle State) {
super.onCreate(State);
setContentView(R.layout.main);
AlertDialog.Builder alertbox = new AlertDialog.Builder(this);
// set the message to display
alertbox.setMessage("Disclaimer popup window sample..hai.kjidj kjdij idfjdfojodifjdojfodjfodijfoidjfoidjf kdfjdifudjf difjdfjodfjdjfodf jd fojjidjfdfjdofjdfojfodjfodjfodjfojdfojdfojdofjodjfodjfl dfjdofjdofj dfdjfodjf difjdoifj dfijdf ");
// set a positive/yes button and create a listener
alertbox.setPositiveButton("Agree/Close", new DialogInterface.OnClickListener() {
// do something when the button is clicked
public void onClick(DialogInterface dialog, int arg1) {
dialog.cancel();
}
});
// set a negative/no button and create a listener
alertbox.setNegativeButton("Buy", new DialogInterface.OnClickListener() {
// do something when the button is clicked
public void onClick(DialogInterface arg0, int arg1) {
arg0.cancel();
}
});
// display box
alertbox.show();
}
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_MENU)) {
//Dialog dialog = null;
moveTaskToBack(true);
//return true;
// dialog.dismiss();
}
return super.onKeyDown(keyCode, event);
}
}
