我有一个按钮和一个图像视图。这样做的目的是在每次单击按钮时为imageview设置动画。然而，我只能在第一次点击时才能做到。
随后的单击不会使imageviw产生动画效果。我不确定为什么会发生这种情况。谢谢
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final ImageView image = findViewById(R.id.image);
final Button button = findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
image.setVisibility(View.VISIBLE);
image.animate().scaleX(1.4f).scaleY(1.4f).setDuration(200).start();
final Handler handler = new Handler();
new Thread(new Runnable() {
@Override
public void run() {
try {
Thread.sleep(500);
handler.post(new Runnable() {
@Override
public void run() {
image.setVisibility(View.INVISIBLE);
}
});
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}).start();
}
});
}
