从一侧的屏幕外到另一侧的屏幕外进行 Translate TranslateAnimation
Doing Translate TranslateAnimation from just outside the screen on one side to just outside the screen on the other side
我有一个名为 myimage 的 ImageView。
我正在这样做 TranslateAnimation 从屏幕的一侧到屏幕的另一侧。
Animation animation = new TranslateAnimation(0, 0, -1500, 1500);
animation.setDuration(1000);
animation.setFillAfter(false);
myimage.startAnimation(animation);
有什么方法可以让我将它从一侧屏幕外移动到另一侧屏幕外,而不管屏幕尺寸如何?
我已经拿到了
DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
final float screen_width_half = metrics.widthPixels/2;
final float distance = screen_width_half + 50;
//determine half screen width and add 50 to it to take it just a little outside the screen
Animation animation =
new TranslateAnimation(0, 0, -distance, distance);
animation.setDuration(1000);
animation.setFillAfter(false);
myimage.startAnimation(animation);
