问题描述

我已经实现了一个手势来提示用户我们在 iOS 应用中的滑动选项.它看起来像-

I have implemented a gesture to hint user of the swipe options that we have in our iOS app. Its looking like-

我是 Android 应用开发的新手.我已经实现了除动画之外的所有内容，例如屏幕.如何在 Android 应用程序中为回收站视图项添加相同的动画?

I am new to Android app development. I have implemented everything like the screen except the animation. How do I add same animation in Android application for recycler view items?

推荐答案

最后，我自己实现了.

这里是item_layout.xml-

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <View
        android:id="@+id/leftView"
        android:layout_width="100dp"
        android:layout_height="match_parent"
        android:layout_alignTop="@+id/main_layout"
        android:layout_alignBottom="@id/main_layout"
        android:layout_alignParentStart="true"
        android:background="@color/darkGray" />

    <View
        android:id="@+id/rightView"
        android:layout_width="100dp"
        android:layout_height="match_parent"
        android:layout_alignTop="@+id/main_layout"
        android:layout_alignBottom="@+id/main_layout"
        android:layout_alignParentEnd="true"
        android:background="@color/darkRed" />

    <RelativeLayout id="@+id/main_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
        ...
    </RelativeLayout>    

</RelativeLayout>

这是RecyclerView.Adapter 实现-

@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_layout, parent, false);

    return new ViewHolder(view);
}

@Override
public void onBindViewHolder(final ViewHolder holder, int position) {
    ....
    ....

    if (position == 0) {
        ObjectAnimator animationLeft = ObjectAnimator.ofFloat(holder.swipeLayout, "translationX", 0f, 80f, 0f, -80f, 0f);
        animationLeft.setDuration(1500);
        animationLeft.start();
    }
}
