Advanced six Android UI interface (interface 3D rotation)

Inf. Perhaps you pay the not necessarily to be rewarded, but do not pay must not be rewarded.

Example one:

Here is the Res/layout/activity_main.xml layout file:

<?xml version= "1.0" encoding= "Utf-8"? ><linearlayout xmlns:android= "http://schemas.android.com/apk/res/    Android "android:id=" @+id/layout_main "android:layout_width=" fill_parent "android:layout_height=" Wrap_content " android:orientation= "vertical" ><textview android:id= "@+id/title" android:layout_width= "Wrap_content" Androi d:layout_height= "wrap_content" android:layout_gravity= "center" android:gravity= "Center" android:textcolor= "# ff0000 "android:text=" @string/txt_main "/> <linearlayout android:layout_margintop=" 50dip "Android:layout_ Width= "Wrap_content" android:layout_height= "wrap_content" android:gravity= "center" android:layout_gravity= "center "><buttonandroid:id=" @+id/main_last "android:layout_width=" wrap_content "android:layout_height=" Wrap_ Content "android:text=" on page "/><button android:id=" @+id/main_next "android:layout_marginleft=" 50dip "Android: Layout_width= "Wrap_content" android:layout_height= "Wrap_content" android:text= "next page"/></linearlaYout></linearlayout> 

here is the Res/layout/next.xml layout file:

<?xml version= "1.0" encoding= "Utf-8"? ><linearlayout xmlns:android= "http://schemas.android.com/apk/res/    Android "android:id=" @+id/layout_next "android:layout_width=" fill_parent "android:layout_height=" Wrap_content " android:orientation= "vertical" ><textview android:id= "@+id/title" android:layout_width= "Wrap_content" Androi d:layout_height= "wrap_content" android:layout_gravity= "center" android:gravity= "Center" android:textcolor= "# ff0000 "android:text=" @string/txt_next "/> <linearlayout android:layout_margintop=" 5dip "android:layout_width = "Wrap_content" android:layout_height= "wrap_content" android:gravity= "center" android:layout_gravity= "Center" > <buttonandroid:id= "@+id/next_last" android:layout_width= "wrap_content" android:layout_height= "Wrap_content" Android:text= "Previous"/><button android:id= "@+id/next_next" android:layout_marginleft= "50dip" Android:layout_ Width= "Wrap_content" android:layout_height= "Wrap_content" android:text= "next page"/></linearlayOut></linearlayout> 

here is the Res/values/string.xml file:

<?xml version= "1.0" encoding= "Utf-8"?><resources>    <string name= "App_name" >rotate3d</ string>    <string name= "Hello_world" >hello world!</string>    <string name= "Action_settings" >Settings</string>    <string name= "Txt_main" > the first page \ n \ nyou Cherish life </string>    <string name= " Txt_next "> second page \ n away from it</string></resources>

here is the Rotate3d.java file:

public class Rotate3d extends Animation {private float fromdegree;//rotation start angle private float todegree;//rotation end angle Private float m centerx;//Rotary Center xprivate float mcentery;//Rotary Center yprivate Camera mcamera;public Rotate3d (float fromdegree, float todegree, F Loat CenterX, float centery) {this.fromdegree = Fromdegree;this.todegree = Todegree;this.mcenterx = CenterX; This.mcentery = CenterY;} @Overridepublic void Initialize (int width, int height, int parentwidth, int parentheight) {super.initialize (width, height , Parentwidth, parentheight); Mcamera = new Camera ();} @Overrideprotected void Applytransformation (float interpolatedtime, transformation t) {final float Fromdegree = Fromdegree;float degrees = Fromdegree + (todegree-fromdegree) * interpolatedtime;//rotation angle (angle) Final float CenterX = mCe nterx;final float centery = mcentery;final Matrix matrix = T.getmatrix (); if (degrees <= -76.0f) {degrees = -90.0f;mcame Ra.save (); Mcamera.rotatey (degrees);//Spin 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);//Displacement xmcamera.rotatey (degrees); mcamera.translate (0, 0,- CenterX); Mcamera.getmatrix (matrix); Mcamera.restore ();} Matrix.pretranslate (-centerx,-centery); Matrix.posttranslate (CenterX, CenterY);}}

here is the Mainactivity.java main interface file:
