Android动画之逐帧动画

android帧动画，有两种，一种是在xml,一种是在代码；下面我们来看看怎么逻辑实现；
１．首先是在res/drawable文件夹下添加img图，如15张－不等；
在drawable添加xml文件android_frame_animation.xml

<?xml version="1.0" encoding="utf-8"?>
<!-- oneshot　false设置会一直播放，true只播放一遍-->
<animation-list xmlns:android="http://schemas.android.com/apk/res/android"
    android:oneshot="true" >
    <item android:drawable="@mipmap/image_icon1" android:duration="150"/>
    <item android:drawable="@mipmap/image_icon2" android:duration="150"/>
    <item android:drawable="@mipmap/image_icon3" android:duration="150"/>
    <item android:drawable="@mipmap/image_icon4" android:duration="150"/>
    <item android:drawable="@mipmap/image_icon5" android:duration="150"/>
    <item android:drawable="@mipmap/image_icon6" android:duration="150"/>
    <item android:drawable="@mipmap/image_icon7" android:duration="150"/>
    <item android:drawable="@mipmap/image_icon8" android:duration="150"/>
    <item android:drawable="@mipmap/image_icon9" android:duration="150"/>
    <item android:drawable="@mipmap/image_icon10" android:duration="150"/>
    <item android:drawable="@mipmap/image_icon11" android:duration="150"/>
    <item android:drawable="@mipmap/image_icon13" android:duration="150"/>
    <item android:drawable="@mipmap/image_icon14" android:duration="150"/>
    <item android:drawable="@mipmap/image_icon15" android:duration="150"/>
</animation-list>

res/layout创建布局；
main_frame_animation_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@color/transparent"
    android:focusable="true"
    android:focusableInTouchMode="true"
    android:orientation="vertical">

    <LinearLayout
        android:layout_width="230dp"
        android:layout_height="70dp"
        android:layout_centerInParent="true"
        android:background="@drawable/android_frame_animation"
        android:gravity="center"
        android:orientation="horizontal"
        android:paddingBottom="8dip"
        android:paddingTop="8dip">

        <ImageView
            android:id="@+id/imageView1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />

    </LinearLayout>

    <Button
        android:id="@+id/butt1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
</LinearLayout>

看mainActivity方法；

package com.personal.myapplication;

import android.graphics.drawable.AnimationDrawable;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;

public class MainActivity extends AppCompatActivity {

    private Button bt1;
    private ImageView image3;
    private AnimationDrawable ani;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main_frame_animation_layout);
        bt1=(Button)findViewById(R.id.butt1);
        image3=(ImageView)findViewById(R.id.imageView1);
        image3.setBackgroundResource(R.drawable.vargo_user_dialog);
        ani = (AnimationDrawable)image3.getBackground();
        bt1.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View view) {
                ani.start();

            }
        });

    }

}

第二种，代码实现

/** 
 * 通过代码添加帧动画方法 
 */  
public void setCodeFrameAnim() {  

    animationDrawable = new AnimationDrawable();  
    // 为AnimationDrawable添加动画帧    
    animationDrawable.addFrame(  
            getResources().getDrawable(R.drawable.image_icon1), 150);  
    animationDrawable.addFrame(  
            getResources().getDrawable(R.drawable.image_icon2), 150);  
    animationDrawable.addFrame(  
            getResources().getDrawable(R.drawable.image_icon3), 150);  
    animationDrawable.addFrame(  
            getResources().getDrawable(R.drawable.image_icon4), 150);  
    animationDrawable.addFrame(  
            getResources().getDrawable(R.drawable.image_icon5), 150);  
    animationDrawable.addFrame(  
            getResources().getDrawable(R.drawable.image_icon6), 150);  
    animationDrawable.addFrame(  
            getResources().getDrawable(R.drawable.image_icon7), 150);  
    animationDrawable.addFrame(  
            getResources().getDrawable(R.drawable.image_icon8), 150);  
    animationDrawable.addFrame(  
            getResources().getDrawable(R.drawable.image_icon9), 150);  
    animationDrawable.addFrame(  
            getResources().getDrawable(R.drawable.image_icon10), 150);  
    animationDrawable.addFrame(  
            getResources().getDrawable(R.drawable.image_icon11), 150);  
    animationDrawable.addFrame(  
            getResources().getDrawable(R.drawable.image_icon12), 150);  
    animationDrawable.addFrame(  
            getResources().getDrawable(R.drawable.image_icon13), 150);  
    animationDrawable.addFrame(  
            getResources().getDrawable(R.drawable.image_icon14), 150);  
    animationDrawable.addFrame(  
            getResources().getDrawable(R.drawable.image_icon15), 150);  
    // 设置为循环播放  
    animationDrawable.setOneShot(false);  
    imageView.setBackground(animationDrawable);

以上就算完成了…
