非常簡單的sample 關於animation

1. 先在res/anim 目碌下加上一個xml:

http://schemas.android.com/apk/res/android"
      android:shareInterpolator="false">
        android:interpolator= "@android:anim/accelerate_decelerate_interpolator"
     android:fromXScale="0.0"
     android:toXScale="1.4"
     android:fromYScale="0.0"
     android:toYScale="1.4"
     android:pivotX="50%"
     android:pivotY="50%"
     android:fillAfter="false"
     android:startOffset="700"
     android:duration="2000"
     android:repeatCount="10"
     />

2. 在res/drawable 加上圖片 (my_image.jpg)

3. 在main.xml 加上

http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
android:id="@+id/spaceshipImage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/my_image"/>

4. 在主要的.java 加編寫

package com.android.ani;

import com.android.ani.R;
import android.app.Activity;
import android.content.res.Resources;
import android.content.res.Resources.NotFoundException;
import android.graphics.drawable.TransitionDrawable;
import android.os.Bundle;
import android.util.Log;
import android.view.ViewGroup.LayoutParams;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.Gallery;
import android.widget.ImageView;
import android.widget.LinearLayout;

public class animDo extends Activity {
    LinearLayout mLinearLayout;

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        ImageView spaceshipImage = (ImageView) findViewById(R.id.spaceshipImage);
        Animation hyperspaceJumpAnimation = AnimationUtils.loadAnimation(this, R.anim.hyperspace_jump);
        spaceshipImage.startAnimation(hyperspaceJumpAnimation);   !!!!!!!!!!!!!! 問題在這句 !!!!!!!!!!!!!
    }
}
