这里我就直接贴了:
package com.ata.util; import android.view.animation.Animation; import android.view.animation.Transformation; import android.graphics.Camera; import android.graphics.Matrix; /** * An animation that rotates the view on the Y axis between two specified angles. * This animation also adds a translation on the Z axis (depth) to improve the effect. */ public class Rotate3dAnimation extends Animation { private final float mFromDegrees; private final float mToDegrees; private final float mCenterX; private final float mCenterY; private final float mDepthZ; private final boolean mReverse; private Camera mCamera; /** * Creates a new 3D rotation on the Y axis. The rotation is defined by its * start angle and its end angle. Both angles are in degrees. The rotation * is performed around a center point on the 2D space, definied by a pair * of X and Y coordinates, called centerX and centerY. When the animation * starts, a translation on the Z axis (depth) is performed. The length * of the translation can be specified, as well as whether the translation * should be reversed in time. * * @param fromDegrees the start angle of the 3D rotation * @param toDegrees the end angle of the 3D rotation * @param centerX the X center of the 3D rotation * @param centerY the Y center of the 3D rotation * @param reverse true if the translation should be reversed, false otherwise */ public Rotate3dAnimation(float fromDegrees, float toDegrees, float centerX, float centerY, float depthZ, boolean reverse) { mFromDegrees = fromDegrees; mToDegrees = toDegrees; mCenterX = 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 interpolatedTime, 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(); 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); } }
接下来就是要在ViewFlipper中使用它了,
首先在布局中加入2个view,类似:
<ViewFlipper android:id="@+id/viewFlipper" android:layout_width="fill_parent" android:layout_height="fill_parent" > <include layout="@layout/layout_0"/> <include layout="@layout/layout_1"/> </ViewFlipper>
然后通常在代码中怎样写:
我这里是按一个按钮将2个ListView翻来覆去的3D旋转显示。
View.OnClickListener onClickListener=new View.OnClickListener(){ @Override public void onClick(View v) { // TODO Auto-generated method stub float halfWidth=viewFlipper.getWidth()/2.0f; float halfHeight=viewFlipper.getHeight()/2.0f; int duration=500; int depthz=0;//viewFlipper.getWidth()/2; if(btn_rightTop.getText().equals("日历视图")){ btn_rightTop.setText("分类视图"); Rotate3dAnimation in=new Rotate3dAnimation(-90, 0,halfWidth,halfHeight,depthz,false); in.setDuration(duration); in.setStartOffset(duration); viewFlipper.setInAnimation(in); Rotate3dAnimation out=new Rotate3dAnimation(0, 90,halfWidth,halfHeight,depthz,false); out.setDuration(duration); viewFlipper.setOutAnimation(out); viewFlipper.showNext(); }else{ btn_rightTop.setText("日历视图"); Rotate3dAnimation in=new Rotate3dAnimation(90, 0,halfWidth,halfHeight,depthz,false); in.setDuration(duration); in.setStartOffset(duration); viewFlipper.setInAnimation(in); Rotate3dAnimation out=new Rotate3dAnimation(0, -90,halfWidth,halfHeight,depthz,false); out.setDuration(duration); viewFlipper.setOutAnimation(out); viewFlipper.showPrevious(); } } };
这样一个简单的3D旋转效果就出来了。就是感觉景深效果不太好,比较生硬,没iphone自然。
