Updating TextView every N seconds?
I've been very confused about this recently and can't find an answer anywhere.
When programming for android, I want to update a textview every 10 seconds, but how would I go about that? I've seen some samples use "Run()" and "Update()", but that doesn't seem to help when I try it, any ideas?
Right now I have:
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.slideshow);
CONST_TIME = (int) System.currentTimeMillis();
Resources res = getResources();
myString = res.getStringArray(R.array.myArray);
}
public void checkTime(View V){
TextView text = (TextView) findViewById(R.id.fadequote);
CUR_TIME = (int) System.currentTimeMillis();
text.setText(""+(int) (CUR_TIME-CONST_TIME));//Debugs how much time has gone by
if(CUR_TIME-CONST_TIME>10000){
getNextQuote(null); //A function that gets a random quote
CONST_TIME = CUR_TIME;
}
}
I guess what I'm REALLY asking is how do I make checkTime() repeat it-self endlessly until onPause() is called?

Rather than fuss with a background thread and then runOnUiThread(), use postDelayed(), available on any View, to schedule a Runnable. That Runnable can update your TextView and then schedule itself for the next pass. Using a background thread for the purposes of watching time tick by is a waste.
