I´m new to android-programming and for the first programm I was trying to do a simple Pong-Clone. My programm is stitched together from different how-to´s and the little bit I was able to handle myself.
The baseline: When I press the "play" button it calls my "GameActivity" which sets my "GameView" as its ContentView. Inside the GameView I handle everything from the game, the ball bouncing, the player(s) and the enemy. But my problem is how to get out of it once one player wins.
At first I wanted to simply call a dialog wich asks the player if he wants to play again or go back to the menu, but I cant do anything Activity related of course, because im in the "GameView". If I try to it always tells me I cant because "non-static methods cannot be referenced from a static context".
So my GameActivity is quite simple:
public class GameActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(new GameView(this));
}
}
At first I simply to put something like this into my View:
InfoDialog infoDialog = new InfoDialog();
infoDialog.show(getSupportFragmentManager(), "infoDialog");
But as I said as far as I understood I can´t do that in a View.
TLDR: How can I stop or change the ContentView from my Activity or call a dialog inside that View?
Like I said im very new to Android-programming so sorry if the way that I did this is very convoluted.
You can save the context of this activity on the GameView constructor and use it when you need:
class GameView extends View {
private Context mContext;
//Constructor
public GameView (Context context) {
super(context);
mContext = context
}
//Can be called inside the view
public ShowDialog() {
AlertDialog alertDialog = new AlertDialog.Builder(mContext).create();
alertDialog.setTitle("Alert");
alertDialog.setMessage("Alert message to be shown");
alertDialog.setButton(AlertDialog.BUTTON_NEUTRAL, "OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
alertDialog.show();
}
}
