Android開發：Frame-By-Frame Animations的使用方法

Android開發：Frame-By-Frame Animations的使用方法

1. <?xml version="1.0" encoding="utf-8"?>
2. <animation-list xmlns:android="http://schemas.android.com/apk/res/android"
3. android:oneshot="false">
4. <item android:drawable="@drawable/nv1" android:duration="500" />
5. <item android:drawable="@drawable/nv2" android:duration="500" />
6. <item android:drawable="@drawable/nv3" android:duration="500" />
7. <item android:drawable="@drawable/nv4" android:duration="500" />
8. </animation-list>

首先是建在res的drawable目錄下面建一個 anmi_nv.xml文件，再寫上上面的配置。

下面是MainActivity：

1. package mars.animations05;
3. import android.app.Activity;
4. import android.graphics.drawable.AnimationDrawable;
5. import android.os.Bundle;
6. import android.view.View;
7. import android.view.View.OnClickListener;
8. import android.widget.Button;
9. import android.widget.ImageView;
11. public class MainActivity extends Activity {
12. private Button button = null;
13. private ImageView imageView = null;
14. @Override
15. public void onCreate(Bundle savedInstanceState) {
16. super.onCreate(savedInstanceState);
17. setContentView(R.layout.main);
18. imageView = (ImageView)findViewById(R.id.imageViewId);
19. button = (Button)findViewById(R.id.buttonId);
20. button.setOnClickListener(new ButtonListener());
21. }
23. private class ButtonListener implements OnClickListener{
25. public void onClick(View v) {
26. imageView.setBackgroundResource(R.drawable.anim_nv);
27. AnimationDrawable animationDrawable = (AnimationDrawable)imageView.getBackground();
28. animationDrawable.start();
29. }
31. }
32. }

main.xml：

1. <?xml version="1.0" encoding="utf-8"?>
2. <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
3. android:orientation="vertical" android:layout_width="fill_parent"
4. android:layout_height="fill_parent">
6. <Button android:id="@+id/buttonId" android:layout_width="fill_parent"
7. android:layout_height="wrap_content" android:layout_alignParentBottom="true"
8. android:text="測試動畫效果" />
11. <LinearLayout android:orientation="vertical"
12. android:layout_width="fill_parent" android:layout_height="fill_parent">
14. <ImageView android:id="@+id/imageViewId"
15. android:layout_width="wrap_content" android:layout_height="wrap_content"
16. android:layout_centerInParent="true" android:layout_marginTop="100dip"
17. />
18. </LinearLayout>
19. </RelativeLayout>
