Question

I’ve made the logic for showing a confirm dialog when the user press back button by overriding backPressed method, but this implies an unusual behaviour. If soft input keyboard is shown, on back key event, it must be hidden and other back key event must launch the confirmation dialog. There is a way to achieve this? Maybe by detecting if soft input keyboard is up and bypass the confirmation dialog?

Here is a code sample to make this clear:

public boolean onKeyUp(int keyCode, KeyEvent event) 
{
    if (keyCode == KeyEvent.KEYCODE_BACK) 
    {
              //here is the mystery 
              if (soft keyboard is visible)
              {
                    return super.onKeyUp(keyCode, event);
              } else
              {
                                //method which shows the close dialog and close the application
                    onBackPressed();
                    return true;
              }
    }
              return super.onKeyUp(keyCode, event);
 }

Answer 1

if soft keyboard is shown ,I don’t think Activity can receive back key event. the default behaviour is back key make soft keyboard disappear.

View also can block key event, the simple way is setOnKeyListener. make sure that your View is focusable and when it receive back key event just return true .
