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>
