启动画面淡入淡出动画问题
[英]Splash Screen Fade Animation issue
问题描述
我完成了一个fade动画，在初始屏幕中显示了three images 。
但是我有two issue ：
时间加载：
- 加载初始屏幕花了更多时间，需要尽快进入应用程序。
应用无法关闭：
进入应用程序后，我试图在模拟器中使用后退按钮关闭这些应用程序，但是它永远不会关闭
应用。它停留在应用程序本身中。在日志猫中，我看到1,2和3循环一次又一次地继续。我无法关闭我的应用程序。
如果按主屏幕按钮，它将显示主屏幕，但再次自动进入应用程序。
LogCat：
我没有收到任何logcat错误。但是您可以看到logcat读数始终在运行。它永远不会停止。循环1,2和3连续读取logcat。对于这些来说，它永远不会关闭应用程序。按钮，将显示主屏幕。但是有时它会自动进入这些应用程序。

下面，我发布了与SplashActivity相关的整个核心。
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) {
//
// finish();
// android.os.Process.killProcess(android.os.Process.myPid());
// }
/**
* Helper method to start the animation on the splash screen
*/
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");
}
}
