下面图片即为本次的运行效果:java
1.进场动画是在viewholder中的onViewAttachedToWindow()中添加动画便可,动画的代码:
private ScaleInAnimation mSelectAnimation = new ScaleInAnimation();
@Override
public void onViewAttachedToWindow(DiffVH holder) {
super.onViewAttachedToWindow(holder);
addAnimation(holder);
}
private void addAnimation(DiffVH holder) {
for (Animator anim : mSelectAnimation.getAnimators(holder.itemView)) {
anim.setDuration(300).start();
anim.setInterpolator(new LinearInterpolator());
}
}
ScaleInAnimation.java:android
import android.animation.Animator;
import android.animation.ObjectAnimator;
import android.view.View;
public class ScaleInAnimation{
private static final float DEFAULT_SCALE_FROM = .5f;
private final float mFrom;
public ScaleInAnimation() {
this(DEFAULT_SCALE_FROM);
}
public ScaleInAnimation(float from) {
mFrom = from;
}
public Animator[] getAnimators(View view) {
ObjectAnimator scaleX = ObjectAnimator.ofFloat(view, "scaleX", mFrom, 1f);
ObjectAnimator scaleY = ObjectAnimator.ofFloat(view, "scaleY", mFrom, 1f);
return new ObjectAnimator[]{scaleX, scaleY};
}
}
2.每一个item的点击效果是一个自定义view,具体看BamLinearLayout.java
使用的话直接在xml中引用便可:git
<com.example.diffut.BamLinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="120dp"
android:layout_marginBottom="1dp"
android:padding="5dp"
android:background="@mipmap/background"
android:orientation="vertical">
<TextView
android:id="@+id/tv1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="22sp"
android:textStyle="bold"
tools:text="第一个" />
<TextView
android:id="@+id/tv2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="24sp"
android:textStyle="bold"
tools:text="个人存在只为了证实定向刷新中的定向刷新" />
<com.example.diffut.TextSwitchView
android:id="@+id/switchView"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</com.example.diffut.BamLinearLayout>
