1、簡(jiǎn)單實(shí)現(xiàn)Android圖片翻轉(zhuǎn)動(dòng)畫效果不說廢話，先看效果。這是原始圖片的樣子這是翻轉(zhuǎn)后的效果圖如果是你想要的效果，那么繼續(xù)往下看，如果不是，那可以跳過了。這是一個(gè)動(dòng)畫，而不是用matrix實(shí)現(xiàn)的直接翻轉(zhuǎn)圖片?？赡芫W(wǎng)上有很多例子了，但我這是我自己實(shí)驗(yàn)過的，單純的翻轉(zhuǎn)一張圖片。我這個(gè)是根據(jù)APIDemo簡(jiǎn)單修改寫的需要一個(gè)Rotate3d 類，繼承Animationpublic class Rotate3d extends Animationprivate final float mFromDegrees; private final float mToDegrees; private final

2、 float mCenterX; private final float mCenterY; private final float mDepthZ; private final boolean mReverse; private Camera mCamera; public Rotate3d(float fromDegrees, float toDegrees, float centerX, float centerY, float depthZ, boolean reverse) mFromDegrees = fromDegrees; mToDegrees = toDegrees; mCe

3、nterX = centerX; mCenterY = centerY; mDepthZ = depthZ; mReverse = reverse; Override public void initialize(int width, int height, int parentWidth, int parentHeight) super.initialize(width, height, parentWidth, parentHeight); mCamera = new Camera(); Override protected void applyTransformation(float i

4、nterpolatedTime, Transformation t) final float fromDegrees = mFromDegrees; float degrees = fromDegrees + (mToDegrees - fromDegrees) * interpolatedTime); final float centerX = mCenterX; final float centerY = mCenterY; final Camera camera = mCamera; final Matrix matrix = t.getMatrix(); camera.save();

5、if (mReverse) camera.translate(0.0f, 0.0f, mDepthZ * interpolatedTime); else camera.translate(0.0f, 0.0f, mDepthZ * (1.0f - interpolatedTime); camera.rotateY(degrees); camera.getMatrix(matrix); camera.restore(); matrix.preTranslate(-centerX, -centerY); matrix.postTranslate(centerX, centerY); 這個(gè)類可以直接

6、拷過去，不用做任何的修改。其中的方法自己找相關(guān)資料研究。在main.xml里加個(gè)ImageView，如這個(gè)不需要解釋吧，都可以看懂的最后，還需要一個(gè)activity類如：public class TestRotate extends Activity implements OnClickListenerprivate mageView imageview;private ViewGroup mContainer;/* *這個(gè)變量設(shè)置的是圖片，如果是多張圖片，那么可以用數(shù)組，如 *private static final int IMAGE = new int *R.drawable.ro, *

7、R.drawable.icon *; *有多少圖片就放多少，我這里做的只是一張圖片的翻轉(zhuǎn) * */private static final int IMAGE = R.drawable.ro; /* Called when the activity is first created. */ Override public void onCreate(Bundle savedInstanceState) super.onCreate(savedInstanceState); setContentView(R.layout.main); imageview = (ImageView) findVi

8、ewById(R.id.image); mContainer = (ViewGroup) findViewById(R.id.container); /* * 設(shè)置最新顯示的圖片 * 如果是數(shù)組，那么可以寫成IMAGEint * */ imageview.setImageResource(IMAGE); /* * * 設(shè)置ImageView的OnClickListener * */ imageview.setClickable(true); imageview.setFocusable(true); imageview.setOnClickListener(this); private voi

9、d applyRotation(int position, float start, float end) / Find the center of the container final float centerX = mContainer.getWidth() / 2.0f; final float centerY = mContainer.getHeight() / 2.0f; final Rotate3d rotation = new Rotate3d(start, end, centerX, centerY, 310.0f, true); rotation.setDuration(5

10、00); rotation.setFillAfter(true); rotation.setInterpolator(new AccelerateInterpolator(); rotation.setAnimationListener(new DisplayNextView(position); mContainer.startAnimation(rotation); Overridepublic void onClick(View v) / TODO Auto-generated method stub/* * * 調(diào)用這個(gè)方法，就是翻轉(zhuǎn)圖片 * 參數(shù)很簡(jiǎn)單，大家都應(yīng)該看得懂 * 簡(jiǎn)單說下

11、，第一個(gè)是位置，第二是開始的角度，第三個(gè)是結(jié)束的角度 * 這里需要說明的是，如果是要回到上一張 * 把第一個(gè)參數(shù)設(shè)置成-1就行了 * */applyRotation(0,0,90);private final class DisplayNextView implements Animation.AnimationListener private final int mPosition; private DisplayNextView(int position) mPosition = position; public void onAnimationStart(Animation animat

12、ion) public void onAnimationEnd(Animation animation) mContainer.post(new SwapViews(mPosition); public void onAnimationRepeat(Animation animation) /* * This class is responsible for swapping the views and start the second * half of the animation. */ private final class SwapViews implements Runnable p

13、rivate final int mPosition; public SwapViews(int position) mPosition = position; public void run() final float centerX = mContainer.getWidth() / 2.0f; final float centerY = mContainer.getHeight() / 2.0f; Rotate3d rotation; if (mPosition -1) imageview.setVisibility(View.VISIBLE); imageview.requestFoc

14、us(); rotation = new Rotate3d(90, 180, centerX, centerY, 310.0f, false); else imageview.setVisibility(View.GONE); rotation = new Rotate3d(90, 0, centerX, centerY, 310.0f, false); rotation.setDuration(500); rotation.setFillAfter(true); rotation.setInterpolator(new DecelerateInterpolator(); mContainer.startA
