创建android逐帧动画的两种方式

1.设置背景方式

a.在res创建一个anim文件夹，该文件夹下创建animation_list.xml文件

<?xml version="1.0" encoding="utf-8"?> <animation-list xmlns:android="http://schemas.android.com/apk/res/android" android:oneshot="true" > <item android:drawable="@drawable/c1" android:duration="200"/> <item android:drawable="@drawable/c2" android:duration="200"/> <item android:drawable="@drawable/c3" android:duration="200"/> <item android:drawable="@drawable/c4" android:duration="200"/> <item android:drawable="@drawable/c5" android:duration="200"/> <item android:drawable="@drawable/c6" android:duration="200"/> </animation-list>

b. layout文件

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <ImageView android:id="@+id/imageView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerHorizontal="true" android:paddingTop="50dp" > </ImageView> <Button android:id="@+id/button2" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:text="Run" android:onClick="run"> </Button> </LinearLayout>

c.java代码

protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); this.setContentView(R.layout.contextmenu); imageView = (ImageView) findViewById(R.id.imageView1); imageView.setBackgroundResource(R.anim.animation_list); draw = (AnimationDrawable) imageView.getBackground(); // draw = (AnimationDrawable) imageView.getDrawable(); }
public void run(View v) { if (draw.isRunning()) { draw.stop(); } else { draw.stop(); draw.start(); } }

2.设置SRC方式

a.在res创建一个anim文件夹，该文件夹下创建animation_list.xml文件

<?xml version="1.0" encoding="utf-8"?> <animation-list xmlns:android="http://schemas.android.com/apk/res/android" android:oneshot="true" > <item android:drawable="@drawable/c1" android:duration="200"/> <item android:drawable="@drawable/c2" android:duration="200"/> <item android:drawable="@drawable/c3" android:duration="200"/> <item android:drawable="@drawable/c4" android:duration="200"/> <item android:drawable="@drawable/c5" android:duration="200"/> <item android:drawable="@drawable/c6" android:duration="200"/> </animation-list>

b.layout文件

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <ImageView android:id="@+id/imageView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerHorizontal="true" android:src="@anim/animation_list" android:paddingTop="50dp" > </ImageView> <Button android:id="@+id/button2" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:text="Run" android:onClick="run"> </Button> </LinearLayout>

c.layout文件

protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); this.setContentView(R.layout.contextmenu); imageView = (ImageView) findViewById(R.id.imageView1); imageView.setBackgroundResource(R.anim.animation_list); // draw = (AnimationDrawable) imageView.getBackground(); draw = (AnimationDrawable) imageView.getDrawable(); registerForContextMenu(text); }
public void run(View v) { if (draw.isRunning()) { draw.stop(); } else { draw.stop(); draw.start(); } }
