下面我贴我的整个核心与SplashActivity。
Below I posted my entire core related to SplashActivity.
SplashActivity.java：
public class SplashActivity extends Activity {
public int currentimageindex = 0;
Timer timer;
TimerTask task;
ImageView slidingimage;
int count = 0;
private int[] IMAGE_IDS = { R.drawable.spl1, R.drawable.spl2,
R.drawable.spl3 };
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.layout_splash);
final Handler mHandler = new Handler();
// Create runnable for posting
final Runnable mUpdateResults = new Runnable() {
public void run() {
AnimateandSlideShow();
}
};
int delay = 1000; // delay for 1 sec.
int period = 8000; // repeat every 4 sec.
Timer timer = new Timer();
timer.scheduleAtFixedRate(new TimerTask() {
public void run() {
mHandler.post(mUpdateResults);
count = count + 1;
Log.v("test", count + "");
if (count >3) {
Intent i=new Intent(SplashActivity.this,HomeActivity.class);
startActivity(i);
count=0;
}
}
}, delay, period);
}
//
// public void onClick(View v) {

// }
/**

*/
private void AnimateandSlideShow() {
slidingimage = (ImageView) findViewById(R.id.ImageView3_Left);
slidingimage.setImageResource(IMAGE_IDS[currentimageindex
% IMAGE_IDS.length]);
currentimageindex++;
Animation rotateimage = AnimationUtils.loadAnimation(this,
R.anim.custom_anim);
slidingimage.startAnimation(rotateimage);
// Log.v("test","animation slide");
}
}
