I want to create a blinking cursor in a TextView.. So far i got this:
myTv = (TextView)findViewById(R.id.myTv);
//blinking Cursors Thread
class CursorThread extends Thread
{
public void run()
{
while (true)
{
myTv.setText("|");
try
{
sleep(1000);
}
catch (InterruptedException e)
{}
myTv.setText(" ");
try
{
sleep(1000);
}
catch (InterruptedException e)
{}
}
}
}
CursorThread cThread = new CursorThread();
cThread.start();
If i ran this app i get a crash. What m i doing wrong ? Im dont know many things about Threads... Oh and this Thread is an inner class in my MainActivity of course.
Anybody can help ?
You must access the UI thread from another thread with the runOnUI
method like shown here
runOnUiThread(new Runnable() {
public void run() {
keresetTv.setText(" ");
}
});
or by using a handler.post(new Runnable...);
