Andorid Activity跳转动画

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:

  1. package com.asai.android.demo;
  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;
  11. public class demoMain extends Activity {
  12. private Button btnDemo;
  13. private Spinner sprAnim;
  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);
  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 
  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
  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: 

  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>
复制代码



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: 

  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>
复制代码



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: 

  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>
复制代码
