I am developing a chess game, there is progress bar to indicating the
computer is "thinking".
At the start of the game, the progress bar will be hidden in default,
it will be set to visible when the computer is "thinking".
The game board use a surfaceview to draw itself, so the progress bar
is works with the surfaceview.
The progress bar will be controlled in a separate thread using
broadcast to inform UI thread to set the visible status of the
progress bar.
but the progress bar can't be shown as i assume, more of the time, it
will not be shown but as long as it show, it will works fine.
[code]
@Override
public void run() {
callback.showProgressBar();
AISearch();
callback.hideProgressBar();
}
GameMapView.Callback callback = new GameMapView.Callback() {
public void showProgressBar() {
Intent intent = new Intent();
intent.setAction("progress");
intent.putExtra("action", "show");
GameMapActivity.this.sendBroadcast(intent);
}
public void hideProgressBar() {
Intent intent = new Intent();
intent.setAction("progress");
intent.putExtra("action", "hide");
GameMapActivity.this.sendBroadcast(intent);
}
};
public BroadcastReceiver myReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
MyLog.d(TAG, "onReceive");
String action = intent.getStringExtra("action");
if (action.equals("show")) {
MyLog.d(TAG, "show");
mProgress.setVisibility(View.VISIBLE);
}
if (action.equals("hide")) {
MyLog.d(TAG, "hide");
mProgress.setVisibility(View.INVISIBLE);
}
}
};
[code]
any idea about this?
thanks in advance!
