更改ImageView几秒钟并暂停UI

Question

Sorry, I keep on trying to adapt the tokens, but somehow I can't manage this one.

I have the following code:

  timer.schedule(new TimerTask(){

     runOnUiThread(new Runnable() {

      public void run(){
      SplashImage.setImageDrawable(aktieknop);}

      });

  },SplashTime);
  }

Like this the code 'works':

  timer.schedule(new TimerTask(){

    // runOnUiThread(new Runnable() {

      public void run(){
      SplashImage.setImageDrawable(aktieknop);}

    //  });

  },SplashTime);
  }

Can you please help me solving this silly issue? Thanks a lot!

Answer 1

You must call this code line " SplashImage.setImageDrawable(nSplashImage); " from your run method in a runOnUIThread() method like this:

runOnUiThread(new Runnable() {
public void run() {
    SplashImage.setImageDrawable(nSplashImage);
}

});

This is because you cannot change UI components on a non UI thread.

For the splash Screen you can use the Handler and send the delayed message.

Handler splashHandler = new Handler() {

    @Override
    public void handleMessage(Message msg) {
             super.handleMessage(msg);
              //Here you can do what ever you want

           }
         };

int SPLASHTIME=2000;//your wish

splashHandler.sendMessageDelayed(msg, SPLASHTIME);
