How: Start an Activity inside a Thread and use finish() to get back.
- by Kirk Becker
Hello,
I am programming a game on android. I'm using a Thread while calling a Surface View class to update and draw my game. Inside the update I wanted to start an activity based on if the game has just started and this would launch my MENUS.
My Thread for the most part..
while (myThreadRun) {
Canvas c = null;
try {
gameTime = System.currentTimeMillis();
c = myThreadSurfaceHolder.lockCanvas(null);
synchronized (myThreadSurfaceHolder) {
// Update Game.
myThreadSurfaceView.onUpdate();
// Draw Game.
myThreadSurfaceView.onDraw(c);
You can see there where I am updating the game... here is onUpdate();
protected void onUpdate() {
// Test if menu needs to be displayed.
while (thread.getMenu()) {
// Test if menu activity has been started.
if (thread.getMenuRunning() == false) {
Intent menuIntent = new Intent(this.getContext(), MyMenu.class);
((Activity) cxt).startActivityForResult(menuIntent, 1);
thread.setMenuRunning(true);
}
}
I am using a while loop because if I didn't use it the thread just keeps going.
Basically I just don't know how to implement my menus using a thread as a game loop. Everywhere I look it seems like that's best practice.
In my menu activity I just display the menu layout and a few buttons and when the person wants to start the game it uses finish() to go back to my thread where they play the game.
I am very new to this so any insight will be helpful,
Thanks
