android - 如何快速更改图片资源？

Question

我想让它一旦我按下一个按钮，它就会移动并通过快速交换 imageview 中间动画的 src 来制作动画。

我试过使用 Thread.sleep 。

first.setImageResource(R.drawable.cata2);
                first.setImageResource(R.drawable.catb2);

对象动画代码

x += 10
first.setImageResource(R.drawable.cata2);
                ObjectAnimator d = ObjectAnimator.ofFloat(first, "translationX", x);
                d.setDuration(50);
                d.start();

它总是只是切换到 cata2。

Answer 1

Try this one. If the changing image resource not working, try to change it in background resource. Just adjust some duration and the thread sleep.

在 C# 中:

尝试将这些全部放在按钮的监听器中

设置动画

var clockwise = AnimationUtils.LoadAnimation(this.Activity, Resource.Animation.clockwise); clockwise.Duration = 2000;

将您的第一个设置为 cata2

this.Activity.RunOnUiThread(() =>
{
first.setImageResource(R.drawable.cata2);
});

从cata2到catb2随动画变化

Thread t = new Thread(delegate ()

{

first.StartAnimation(clockwise);

Thread.Sleep(500);

this.Activity.RunOnUiThread(() =>

{

first.setImageResource(R.drawable.catb2);

first.ClearAnimation();

return;

});

});

t.Start();
