我想一个接一个地动画一些TextViews
,就像Google即时应用中的卡片一样。我找到了这个question,并尝试遵循其指示,但是所有动画都同时播放。我究竟做错了什么?
这是我要播放的动画:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/accelerate_interpolator" >
<translate
android:duration="@integer/config_slide_time"
android:fromYDelta="100%p"
android:toYDelta="0" />
<alpha
android:duration="@integer/config_slide_time"
android:fromAlpha="0.0"
android:toAlpha="1.0" />
<rotate
android:duration="@integer/config_slide_time"
android:fromDegrees="25"
android:pivotX="0"
android:pivotY="0"
android:toDegrees="0" />
</set>
这是我正在使用的布局:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.yai.properti.tujuh.tujuh.tujuh.ReadUserProfile$PlaceholderFragment" >
<com.yai.app.animation.support.NowLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#e3e3e3"
android:orientation="vertical" >
<TextView
android:id="@+id/txtView"
style="@style/nowCardStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="aaa"
tools:context=".MainActivity" />
<TextView
android:id="@+id/txtView1"
style="@style/nowCardStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="bbb"
tools:context=".MainActivity" />
<TextView
android:id="@+id/txtView2"
style="@style/nowCardStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="ccc"
tools:context=".MainActivity" />
<TextView
android:id="@+id/txtView3"
style="@style/nowCardStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="ddd"
tools:context=".MainActivity" />
<TextView
android:id="@+id/txtView4"
style="@style/nowCardStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="eee"
tools:context=".MainActivity" />
</com.yai.app.animation.support.NowLayout>
</RelativeLayout>
最佳答案
尝试遍历Views
并以Animation
开头postDelayed()
,如下所示:
View[] views = new View[] { ... };
// 100ms delay between Animations
long delayBetweenAnimations = 100l;
for(int i = 0; i < views.length; i++) {
final View view = views[i];
// We calculate the delay for this Animation, each animation starts 100ms
// after the previous one
int delay = i * delayBetweenAnimations;
view.postDelayed(new Runnable() {
@Override
public void run() {
Animation animation = AnimationUtils.loadAnimation(context, R.anim.your_animation);
view.startAnimation(animation);
}
}, delay);
}
