[Android] Frame動畫

1，在drawable資料夾底下新增walking.xml

放入要製作成動畫的圖片：

walking01.png

walking02.png

	<animation-list xmlns:android="http://schemas.android.com/apk/res/android">
	<item android:drawable="@drawable/walking01" android:duration="800"/>
	<item android:drawable="@drawable/walking02" android:duration="800"/>
	</animation-list>

2，在main_activity.xml中新增ImageView，並將背景設成剛剛新增的walking.xml

	<ImageView
	android:id="@+id/ivWalking"
	android:layout_width="wrap_content"
	android:layout_height="wrap_content"
	app:layout_constraintTop_toTopOf="parent"
	app:layout_constraintRight_toRightOf="parent"
	app:layout_constraintLeft_toLeftOf="parent"
	app:layout_constraintBottom_toBottomOf="parent"
	android:background="@drawable/walking"/>

3，在ActivityMain.java中設定動畫

	@Override
	protected void onCreate(Bundle savedInstanceState) {
	super.onCreate(savedInstanceState);
	setContentView(R.layout.activity_main);
	ivWalking = findViewById(R.id.ivWalking);
	AnimationDrawable animationDrawable = (AnimationDrawable) ivWalking.getBackground();
	animationDrawable.start();
	}
