Android uses Animation-list to implement frame-by-frame animation_html/css_WEB-ITnose

The effect we want to achieve

Prepare the resource file and put it under the res/drawable file

Write loading.xml and put it in res/drawable

<!-- animation-list :根标签 oneshot :代表着是否只展示一遍，设置为false会不停的循环播放动画 android :duration 表示该图片的动画时长 -->  <?xml version="1.0" encoding="utf-8"?><animation-list xmlns:android="http://schemas.android.com/apk/res/android" android:oneshot="false" >    <item  android:drawable="@drawable/light01" android:duration="50"/>    <item  android:drawable="@drawable/light02" android:duration="50"/>    <item  android:drawable="@drawable/light03" android:duration="50"/></animation-list>

in the activity_main.xml layout file, like this Write

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical">    <ImageView android:id="@+id/main_img_loading" android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="5px" android:src="@drawable/loading"/>     <Button android:id="@+id/main_bt_start" android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="5px" android:text="开始" />    <Button android:id="@+id/main_bt_stop" android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="5px" android:text="停止" /></LinearLayout>

Write like this in Activity

bt_start.setOnClickListener(new OnClickListener()      {      @Override      public void onClick(View v) {      //获取 AnimationDrawable        animationDrawable = (AnimationDrawable) animationIV.getDrawable();          //开始动画        animationDrawable.start();      }  });   bt_stop.setOnClickListener(new OnClickListener()  {      @Override      public void onClick(View v) {     //获取 AnimationDrawable         animationDrawable = (AnimationDrawable) animationIV.getDrawable();         //停止动画         animationDrawable.stop();      }  });  

Interested children can follow my blog. My column will continue to be updated with Android Studio authoritative tutorials and 2015 I/ I will also share with you the configuration and compilation of NDK at the O conference.
And I received an invitation as a lecturer from CSND. I will record these Android Studio usage tutorials into videos later.
