How do I pause and resume a cycle?
I am an Android nob and I am trying to cut text from an array of a list of strings and display them in the textswitcher. I want the text to change every two seconds. i used this SO question as my explorer and rearranging the text with a button without any problem. However, when I try to loop through the text with a for loop with a 2 second delay, it only displays the first text from arrayList. How do I make the loop run continuously with a pause? Any help is appreciated.
My code;
private void updateCounter()
{
try{
for (int i=0; i< CoinShowReader.tickercontent.size(); i++){
mHandler.postDelayed(new Runnable() {
public void run() {
m_switcher.setText((CoinShowReader.tickercontent.get(CoinShowReader.m_counter)));
CoinShowReader.m_counter++;
}
}, 2000);
}
}catch(Exception e){
e.printStackTrace();
}
}

remove the loop, you don't need that, just schedule the dust to be run inside the handler like this:
void updateTextView(){
m_switcher.setText((CoinShowReader.tickercontent.get(CoinShowReader.m_counter)));
CoinShowReader.m_counter++;
mHandler.postDelayed(new Runnable() {
public void run() {
updateTextView();
} } ,2000); }
}
so each call updateTextView()
assigns the next call, and so on.
Note. remember to insert a trigger to stop this behavior as it is infinite
