没有什么好讲的，先看效果图吧。
主要代码：
package com.iteye.androidtoast; import java.util.ArrayList; import java.util.List; import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.widget.ArrayAdapter; import android.widget.Button; import android.widget.Spinner; public class MainActivity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); final Spinner mAnimSp = (Spinner) findViewById(R.id.animation_sp); Button mButton=(Button) findViewById(R.id.other_button); // 通过资源文件获取Spinner填充内容 String[] ls = getResources().getStringArray(R.array.anim_type); List<String> list = new ArrayList<String>(); // 把数组内容填充 到集合 for (int i = 0; i < ls.length; i++) { list.add(ls<i>); } ArrayAdapter<String> animType = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, list); animType.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); mAnimSp.setAdapter(animType); mAnimSp.setSelection(0); mButton.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Intent intent = new Intent(); intent.setClass(MainActivity.this, OtherActivity.class); startActivity(intent); switch (mAnimSp.getSelectedItemPosition()) { case 0: /*注意：此方法只能在startActivity和finish方法之后调用。 第一个参数为第一个Activity离开时的动画，第二参数为所进入的Activity的动画效果*/ overridePendingTransition(R.anim.fade, R.anim.hold); break; case 1: overridePendingTransition(R.anim.my_scale_action, R.anim.my_alpha_action); break; case 2: overridePendingTransition(R.anim.scale_rotate, R.anim.my_alpha_action); break; case 3: overridePendingTransition(R.anim.scale_translate_rotate, R.anim.my_alpha_action); break; case 4: overridePendingTransition(R.anim.scale_translate, R.anim.my_alpha_action); break; case 5: overridePendingTransition(R.anim.hyperspace_in, R.anim.hyperspace_out); break; case 6: overridePendingTransition(R.anim.push_left_in, R.anim.push_left_out); break; case 7: overridePendingTransition(R.anim.push_up_in, R.anim.push_up_out); break; case 8: overridePendingTransition(R.anim.slide_left, R.anim.slide_right); break; case 9: overridePendingTransition(R.anim.wave_scale, R.anim.my_alpha_action); break; case 10: overridePendingTransition(R.anim.zoom_enter, R.anim.zoom_exit); break; case 11: overridePendingTransition(R.anim.slide_up_in, R.anim.slide_down_out); break; } } }); } } </i>
