Android入门之Gallery+ImageSwitcher用法实例解析（android imageswitcher）
继上一篇介绍了如何使用gallery控件之后，本文就来讲一下gallery 与ImageSwitcher的结合使用。本文所述实例代码将实现一个简单的浏览图片的功能。
先贴出程序运行截图如下：
除了gallery可以拖拉切换图片，我在ImageSwitcher控件加入了setonTouchListener事件实现，使得ImageSwitcher也可以在拖拉中切换图片。本例子依然使用JAVA的反射机制来自动读取资源中的图片。
main.xml的源码如下:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageSwitcher android:id="@+id/switcher"
android:layout_width="match_parent" android:layout_height="match_parent"/>
<gallery android:id="@+id/gallery"
android:background="#55000000"
android:layout_width="match_parent"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:gravity="center_vertical"
android:spacing="16dp" android:layout_height="100dp"/>
</RelativeLayout>
Java程序的源码如下:

Android Gallery ImageSwitcher 求助....
这些图片都是res下面的 ，我想把网页上的图片用这种方式显示出来 。 我的图片都是解析的网页上的，请问 我该怎么做呢。。好心人来帮帮我把。。。
android Gallery 与 imageView 滑动冲突问题解决方法
android Gallery 与 imageView 滑动冲突问题解决方法
1：将 gallery 的触摸事件换成 imageView 的触摸事件
imageView.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
Gallery.onTouchEvent(event);
return false;
}
});
2：重写 Gallrey:
OnIntercepTouchEvent 设置判断 ev.action;

Android ImageSwitcher 实现按钮的 3d 旋转效果
Rotate3d 继承 Android 的 Animation 实现 3d 旋转：
public class Rotate3d extends Animation {
private float mFromDegree;
private float mToDegree;
private float mCenterX;
private float mCenterY;
private float mLeft;
private float mTop;
private Camera mCamera;
private static final String TAG = "Rotate3d";
public Rotate3d(float fromDegree, float toDegree, float left, float top,
float centerX, float centerY) {
this.mFromDegree = fromDegree;
this.mToDegree = toDegree;
this.mLeft = left;
this.mTop = top;
this.mCenterX = centerX;
this.mCenterY = centerY;
}
@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 FromDegree = mFromDegree;
float degrees = FromDegree + (mToDegree - mFromDegree)
* interpolatedTime;
final float centerX = mCenterX;
final float centerY = mCenterY;
final Matrix matrix = t.getMatrix();
if (degrees <= -76.0f) {
degrees = -90.0f;
mCamera.save();
mCamera.rotateY(degrees);
mCamera.getMatrix(matrix);
mCamera.restore();
} else if (degrees >= 76.0f) {
degrees = 90.0f;
mCamera.save();
mCamera.rotateY(degrees);
mCamera.getMatrix(matrix);
mCamera.restore();
} else {
mCamera.save();
//
mCamera.translate(0, 0, centerX);
mCamera.rotateY(degrees);
mCamera.translate(0, 0, -centerX);
mCamera.getMatrix(matrix);
mCamera.restore();
}
matrix.preTranslate(-centerX, -centerY);
matrix.postTranslate(centerX, centerY);
