ListView GridView中item加载显示的动画效果

首先看一下效果图,ListView和GridView中item显示动画

1.ListView中的item加载显示动画

1)直接给ListView设置动画

private void initView() {
setContentView(R.layout.activity_listview);
ListView lv = (ListView) findViewById(R.id.activity_listview_lv);
lv.setLayoutAnimation(getAnimationController());
//        ListViewAdapter  adapter = new ListViewAdapter();
mStrings = new String[]{"A", "S", "D", "F", "G", "H", "J", "Q", "W", "E", "R", "T"};
ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this, R.layout.item_listview_text, R.id.item_listview_tv, mStrings);
lv.setAdapter(arrayAdapter);

}

/**
* Layout动画  即item家在现实的动画,可以更改设置为各种样式
*
* @return
*/
protected LayoutAnimationController getAnimationController() {
int duration = 300;
AnimationSet set = new AnimationSet(true);

Animation animation = new AlphaAnimation(0.0f, 1.0f);
animation.setDuration(duration);
set.addAnimation(animation);

animation = new TranslateAnimation(Animation.RELATIVE_TO_SELF, 0.0f,
Animation.RELATIVE_TO_SELF, 0.0f, Animation.RELATIVE_TO_SELF,
-1.0f, Animation.RELATIVE_TO_SELF, 0.0f);
animation.setDuration(duration);
set.addAnimation(animation);

LayoutAnimationController controller = new LayoutAnimationController(set, 0.5f);
controller.setOrder(LayoutAnimationController.ORDER_NORMAL);
return controller;
}

2)也可以分别给不同的item设置动画

class ListViewAdapter extends BaseAdapter {

private int duration =2000;
private Animation push_left_in, push_right_in;
private Animation slide_top_to_bottom, slide_bottom_to_top;

public ListViewAdapter() {
push_left_in = AnimationUtils.loadAnimation(ListViewActivity.this, R.anim.push_left_in);
push_right_in = AnimationUtils.loadAnimation(ListViewActivity.this, R.anim.push_right_in);
slide_top_to_bottom = AnimationUtils.loadAnimation(ListViewActivity.this, R.anim.slide_top_to_bottom);
slide_bottom_to_top = AnimationUtils.loadAnimation(ListViewActivity.this, R.anim.slide_bottom_to_top);
}

@Override
public int getCount() {
return mStrings.length;
}

@Override
public Object getItem(int position) {
return null;
}

@Override
public long getItemId(int position) {
return 0;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
if (convertView == null) {
holder = new ViewHolder();
convertView = View.inflate(ListViewActivity.this,
R.layout.item_listview_text, null);
holder.tv = (TextView) convertView.findViewById(R.id.item_listview_tv);
convertView.setTag(holder);
if (position % 2 == 0) {
push_left_in.setDuration(duration);
convertView.setAnimation(push_left_in);
} else {
push_right_in.setDuration(duration);
convertView.setAnimation(push_right_in);
}

//                if(position==0){
//                    slide_bottom_to_top.setDuration(duration);
//                    convertView.setAnimation(slide_bottom_to_top);
//                }
//                else{
//                    slide_top_to_bottom.setDuration(duration);
//                    convertView.setAnimation(slide_top_to_bottom);
//                }

} else {
holder = (ViewHolder) convertView.getTag();
}
holder.tv.setText(mStrings[position]);
return convertView;
}
}

class ViewHolder {
TextView tv;
}

资源文件push_left_in.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:fromXDelta="-100%p" android:toXDelta="0" android:duration="300"/>
<alpha android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="300" />
</set>

pubsh_right_in.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:fromXDelta="100%p" android:toXDelta="0" android:duration="300"/>
<alpha android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="300" />
</set>

slide_bottom_to_top.xml

<?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:fromYDelta="100%" android:toXDelta="0" android:duration="300" />
<alpha android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="300" />
</set>

slide_top_to_bottom.xml

<?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:fromYDelta="-100%" android:toXDelta="0" android:duration="300" />
<alpha android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="300" />
</set>

这两种方式的效果是一样的

2.再看一下GridView的动画效果,为了显示更炫酷的效果,这里直接用第二种方式显示动画

import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;

import android.widget.BaseAdapter;
import android.widget.Button;
import android.widget.GridView;
import android.widget.ImageView;

import com.zf.svg.R;

import java.util.Random;

}
private void InitAnima() {

taRight = new TranslateAnimation(Animation.RELATIVE_TO_PARENT, -1.0f,

taLeft.setDuration(1000);

}
private void InitData() {

}

}
});
mInflater = (LayoutInflater) this
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
private class MyAdapter extends BaseAdapter {
@Override
public int getCount() {

return imgList.length;
}
@Override

}
@Override

}
@Override

ViewHolder holder = null;
if (convertView == null) {

Random ran = new Random();
int rand = ran.nextInt(4);
switch (rand) {
case 0:

break;
case 1:

break;
case 2:

break;

}
return convertView;

}
