Question

我已经在XML中设置了五个不同的imageview我想要相同的动画效果，一秒钟延迟。动画必须按顺序依次发生。对于android app中的起始页面，我已经完成了这个。所以我该怎么办这里我的代码

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_welcome);

a=(ImageView)findViewById(R.id.imageView1);
b=(ImageView)findViewById(R.id.imageView2);
c=(ImageView)findViewById(R.id.imageView3);
d=(ImageView)findViewById(R.id.imageView4);
e=(ImageView)findViewById(R.id.imageView5);

aAnimation(savedInstanceState);
bAnimation(savedInstanceState);
cAnimation(savedInstanceState);
dAnimation(savedInstanceState);
eAnimation(savedInstanceState);
}

private void aAnimation(Bundle savedInstanceState) {
    Animation aa=AnimationUtils.loadAnimation(getApplicationContext(),R.anim.slideup);
    a.startAnimation(aa);

}
private void bAnimation(Bundle savedInstanceState) {
    Animation aa=AnimationUtils.loadAnimation(getApplicationContext(),R.anim.slideup);
    b.startAnimation(aa);

}
private void cAnimation(Bundle savedInstanceState) {
    Animation aa=AnimationUtils.loadAnimation(getApplicationContext(),R.anim.slideup);
    c.startAnimation(aa);

}
private void dAnimation(Bundle savedInstanceState) {
    Animation aa=AnimationUtils.loadAnimation(getApplicationContext(),R.anim.slideup);
    d.startAnimation(aa);

}
private void eAnimation(Bundle savedInstanceState) {
    Animation aa=AnimationUtils.loadAnimation(getApplicationContext(),R.anim.slideup);
    e.startAnimation(aa);

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.welcome, menu);
    return true;
}

Answer 1

您可以使用 startOffset

http://developer.android.com/reference/android/view/animation/Animation.html

动画运行前的延迟时间，一旦开始时间为   达到。

例如：

在XML中：

<set android:startOffset="1000"> 
    <scale 
       android:fromXScale="0.5" 
       android:toXScale="1.0" 
       android:fromYScale="0.5" 
       android:toYScale="1.0" 
       android:pivotX="50%" 
       android:pivotY="50%" 
       android:duration="1000" />
</set>

OR

在JAVA中：

Animation aa = AnimationUtils.loadAnimation(getApplicationContext(),R.anim.slideup);
aa.setStartOffset(1000);
a.startAnimation(aa);

Answer 2

您可以使用Handler s延迟

new Handler().postDelayed(new Runnable()
{
   @Override
   public void run()
    {
      // run animation
    }
 }, 1000); //1 sec

不同图像的动画时间
