Question

Okay, I was able to figure out a timer earlier, but now I’m having another problem

So, when I call this function called “getNextQuote();” the first time in onCreate() it updates and gets a random quote and displays it perfectly, however, when I try again, in onResume(), it doesn’t refresh for some reason.

public void getNextQuote(){

    TextView tv = (TextView) findViewById(R.id.quote);//Text To be edited
    Random QuoteNum = new Random();     

    int Quote = QuoteNum.nextInt(50);

    android.util.Log.i("DebugB",""+Quote);

    String q = myString[Quote];//find which string is corresponding to the number
    tv.setText(q);//Set the Text 

    android.util.Log.i("DebugC",q);
}

anything obvious I’m missing???
In the log the new quotes are coming out like there supposed to, but they just arn’t getting drawn to the actual emulator screen.

try this:

int i = 0;

public void getNextQuote(){

runOnUiThread(new Runnable() {

    @Override
    public void run() {
        TextView tv = (TextView) findViewById(R.id.quote);//Text To be edited
        tv.setText("test"+i);//Set the Text
        i++;
    }
});

}

This counts test0, test1, test2,… 🙂 Just put your code into that runOnUiThread. When I tried your code, I got an error (because of the thread). Also check, if your interval is short enough. Just try 1000 msec. 🙂

UPDATE:

Maybe this is a better aproach by reusing the Runnable (don’t really know) 🙂

int i = 0;

Runnable updateTextView = new Runnable() {

    @Override
    public void run() {
        TextView tv = (TextView) findViewById(R.id.text_view);//Text To be edited
        tv.setText("test"+i);//Set the Text
        i++;
    }
};

public void getNextQuote(){

    runOnUiThread(updateTextView);
}
