回答1:
Replace this piece of code :
final Handler mHandler = new Handler();
// Create runnable for posting
final Runnable mUpdateResults = new Runnable() {
public void run() {
AnimateandSlideShow();
}
};
int delay = 1000;
int period = 5000;
Timer timer = new Timer();
timer.scheduleAtFixedRate(new TimerTask() {
public void run() {
mHandler.post(mUpdateResults);
}
}, delay, period);
}
Write instead this code :
final Handler handler = new Handler();
runnable = new Runnable() {
@Override
public void run() {
handler.postDelayed(runnable, 5000);
AnimateandSlideShow();
}
};
handler.postDelayed(runnable, 500);
}
This will lead to start image without delay ,
then you can control the appearance time and the time in between image as you want,
Hope help you .

Try to use postdelay:
private int mSampleDurationTime = 5000; // 1 sec
private boolean continueToNext = true;
Handler mHandler = new Handler();
mHandler.postDelayed(mRunnable, mSampleDurationTime);
where mRunnable is your task:
private final Runnable mRunnable = new Runnable() {
//...
public void run() {
// do something here
if(continueToNext == true){
mHandler.postDelayed(mRunnable, mSampleDurationTime);
}
}
...
};
