how can i avoid that the buttons have focus? i tried some things like messageBox.getCurrentFocus().clearFocus(); but evrything crashed my app.

here is my code:

case askRudeMode:
{   
    messageBox = new AlertDialog.Builder(context).create();
    messageBox.setTitle(dialogSubject);
    messageBox.setMessage(dialogText);
    messageBox.setButton(bubblr.lang.getString("YES"), new OnClickListener() {

    @Override
    public void onClick(DialogInterface dialog, int which) {

        Gdx.app.postRunnable(new Runnable(){
            @Override
            public void run() {
                bubblr.prefs.setRudeMode(false);    //----- disable rudemode -> save to prefs
                bubblr.prefs.setAskRudeMode();
            }
        });
    }
});
messageBox.setButton2(bubblr.lang.getString("NO"), new OnClickListener() {

    @Override
    public void onClick(DialogInterface dialog, int which) {    

        Gdx.app.postRunnable(new Runnable() {
            @Override
            public void run() {
                bubblr.prefs.setRudeMode(true); //----- enable rudemode -> save to prefs
                bubblr.prefs.setAskRudeMode();
            }
        });
    }
});

// messageBox.getCurrentFocus().clearFocus();                                               // führt zu crash der app
//      if (messageBox.getCurrentFocus() != null) messageBox.getCurrentFocus().clearFocus();    // funktioniert nicht :(

    messageBox.show();
    break;
}

other dialogs dont have focussed buttons.... why is that?

bye phil

Answer 1

instead of using only Button make use of positive and negative Buttons as:

case askRudeMode:
{   
    messageBox = new AlertDialog.Builder(context).create();
    messageBox.setTitle(dialogSubject);
    messageBox.setMessage(dialogText);
    messageBox.setPositiveButton(bubblr.lang.getString("YES"), new OnClickListener() {

    @Override
    public void onClick(DialogInterface dialog, int which) {

        Gdx.app.postRunnable(new Runnable(){
            @Override
            public void run() {
                bubblr.prefs.setRudeMode(false);    //----- disable rudemode -> save to prefs
                bubblr.prefs.setAskRudeMode();
            }
        });
    }
});
messageBox.setNegativeButton(bubblr.lang.getString("NO"), new OnClickListener() {

    @Override
    public void onClick(DialogInterface dialog, int which) {    

        Gdx.app.postRunnable(new Runnable() {
            @Override
            public void run() {
                bubblr.prefs.setRudeMode(true); //----- enable rudemode -> save to prefs
                bubblr.prefs.setAskRudeMode();
            }
        });
    }
});

Answer 2

Just add the following code after this call: "messageBox.show();"

Button button = (Button) messageBox.findViewById(android.R.id.button1);
button.setFocusable(false);

This code avoids to focuse your first dialog button.
