Activity之间切换的各种效果(遗憾没有3D的效果)

http://edison-cool911.iteye.com/blog/730320

下面的Demo是我找到的一个觉得用来在程序中进行Activity之间切换的很好的一个例子: 

Java代码  

1. package com.asai.android.demo;  
2.   
3. import android.app.Activity;  
4. import android.content.Intent;  
5. import android.os.Bundle;  
6. import android.view.View;  
7. import android.widget.ArrayAdapter;  
8. import android.widget.Button;  
9. import android.widget.Spinner;  
10.   
11. public class demoMain extends Activity {  
12.     private Button btnDemo;  
13.     private Spinner sprAnim;  
14.   
15.     /** Called when the activity is first created. */  
16.     @Override  
17.     public void onCreate(Bundle savedInstanceState) {  
18.         super.onCreate(savedInstanceState);  
19.         setContentView(R.layout.main);  
20.           
21.         btnDemo = (Button) findViewById(R.id.btnDemo);  
22.         sprAnim = (Spinner) findViewById(R.id.sprAnim);  
23.         //Spinner的内容适配器  
24. ArrayAdapter<?> animType = ArrayAdapter.createFromResource(this,  
25.                 R.array.anim_type, android.R.layout.simple_spinner_item);  
26.         animType.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);  
27.         sprAnim.setAdapter(animType);  
28.                 //默认选中第一项  
29.         sprAnim.setSelection(0);  
30.         btnDemo.setOnClickListener(new View.OnClickListener() {  
31.             public void onClick(View view) {  
32.                 startActivity(new Intent(demoMain.this, demoDetail.class));  
33.                 switch (sprAnim.getSelectedItemPosition()) {  
34.                 case 1:  
35.                 //淡入淡出效果      
36.   
37. overridePendingTransition(R.anim.fade, R.anim.hold);  
38.                     break;  
39.                 case 2:  
40.                     overridePendingTransition(R.anim.alpha_rotate,  
41.                             R.anim.my_alpha_action);  
42.                     break;  
43.                 case 3:  
44.                     overridePendingTransition(R.anim.alpha_scale_rotate,  
45.                             R.anim.my_alpha_action);  
46.                     break;  
47.                 case 4:  
48.                     overridePendingTransition(  
49.                             R.anim.alpha_scale_translate_rotate,  
50.                             R.anim.my_alpha_action);  
51.                     break;  
52.                 case 5:  
53.                     overridePendingTransition(R.anim.alpha_scale_translate,  
54.                             R.anim.my_alpha_action);  
55.                     break;  
56.                 case 6:  
57.                 //中心放大效果  
58.   
59.     overridePendingTransition(R.anim.alpha_scale,  
60.                             R.anim.my_alpha_action);  
61.                     break;  
62.                 case 7:  
63.                     overridePendingTransition(R.anim.alpha_translate_rotate,  
64.                             R.anim.my_alpha_action);  
65.                     break;  
66.                 case 8:  
67.                     overridePendingTransition(R.anim.alpha_translate,  
68.                             R.anim.my_alpha_action);  
69.                     break;  
70.                 case 9:  
71.                     overridePendingTransition(R.anim.my_rotate_action,  
72.                             R.anim.my_alpha_action);  
73.                     break;  
74.                 case 10:  
75.                     overridePendingTransition(R.anim.my_scale_action,  
76.                             R.anim.my_alpha_action);  
77.                     break;  
78.                 case 11:  
79.                     overridePendingTransition(R.anim.my_translate_action,  
80.                             R.anim.my_alpha_action);  
81.                     break;  
82.                 case 12:  
83.                     overridePendingTransition(R.anim.myanimation_simple,  
84.                             R.anim.my_alpha_action);  
85.                     break;  
86.                 case 13:  
87.                     overridePendingTransition(R.anim.myown_design,  
88.                             R.anim.my_alpha_action);  
89.                     break;  
90.                 case 14:  
91.                     overridePendingTransition(R.anim.scale_rotate,  
92.                             R.anim.my_alpha_action);  
93.                     break;  
94.                 case 15:  
95.                     overridePendingTransition(R.anim.scale_translate_rotate,  
96.                             R.anim.my_alpha_action);  
97.                     break;  
98.                 case 16:  
99.                     overridePendingTransition(R.anim.scale_translate,  
100.                             R.anim.my_alpha_action);  
101.                     break;  
102.                 case 17:  
103.                     overridePendingTransition(R.anim.translate_rotate,  
104.                             R.anim.my_alpha_action);  
105.                     break;  
106.                 case 18:  
107.                     overridePendingTransition(R.anim.hyperspace_in,  
108.                             R.anim.hyperspace_out);  
109.                     break;  
110.                 case 19:  
111.                     overridePendingTransition(R.anim.shake,  
112.                             R.anim.my_alpha_action);  
113.                     break;  
114.                 case 20:  
115.                     overridePendingTransition(R.anim.push_left_in,  
116.                             R.anim.push_left_out);  
117.                     break;  
118.                 case 21:  
119.                 //从下方移出效果   overridePendingTransition(R.anim.push_up_in,  
120.                             R.anim.push_up_out);  
121.                     break;  
122.                 case 22:  
123.                     overridePendingTransition(R.anim.slide_left,  
124.                             R.anim.slide_right);  
125.                     break;  
126.                 case 23:  
127.                     overridePendingTransition(R.anim.slide_top_to_bottom,  
128.                             R.anim.my_alpha_action);  
129.                     break;  
130.                 case 24:  
131.                     overridePendingTransition(R.anim.wave_scale,  
132.                             R.anim.my_alpha_action);  
133.                     break;  
134.                 }  
135.             }  
136.         });  
137.     }  
138. }  

另外一个activity可以自己随便写个,这里还用到了就是arrays.xml作为Spinner的适配器: 

Java代码  

1. <?xml version="1.0" encoding="utf-8"?>  
2. <resources>  
3.     <string-array name="anim_type">  
4.         <item>zoom_enter</item>  
5.         <item>fade</item>  
6.         <item>alpha_rotate</item>  
7.         <item>alpha_scale_rotate</item>  
8.         <item>alpha_scale_translate_rotate</item>  
9.         <item>alpha_scale_translate</item>  
10.         <item>alpha_scale</item>  
11.         <item>alpha_translate_rotate</item>  
12.         <item>alpha_translate</item>  
13.         <item>my_rotate_action</item>  
14.         <item>my_scale_action</item>  
15.         <item>my_translate_action</item>  
16.         <item>myanimation_simple</item>  
17.         <item>myown_design</item>  
18.         <item>scale_rotate</item>  
19.         <item>scale_translate_rotate</item>  
20.         <item>scale_translate</item>  
21.         <item>translate_rotate</item>  
22.         <item>hyperspace_in</item>  
23.         <item>shake</item>  
24.         <item>push_left_in</item>  
25.         <item>push_up_in</item>  
26.         <item>slide_left</item>  
27.         <item>slide_top_to_bottom</item>  
28.         <item>wave_scale</item>  
29.     </string-array>  
30. </resources>  

其实这个Demo最重要的就是anim中的一些xml动画定义: 
下面我一个一个的来介绍下(我觉得实用性很好的): 
push_up_in.xml: 

Java代码  

1. <set xmlns:android="http://schemas.android.com/apk/res/android">  
2.     <translate android:fromYDelta="100%p" android:toYDelta="0" android:duration="300"/>  
3.     <alpha android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="300" />  
4. </set>  

相信这段代码我不用解释应该也看的懂:改变y坐标来实现动画效果; 
相对应的就是: 
push_up_out.xml: 

Java代码  

1. <set xmlns:android="http://schemas.android.com/apk/res/android">  
2.     <translate android:fromYDelta="0" android:toYDelta="-100%p" android:duration="300"/>  
3.     <alpha android:fromAlpha="1.0" android:toAlpha="0.0" android:duration="300" />  
4. </set>
