一下，我只把主要的代码贴出来给大家，如果哪里写的不好，希望大家能多多指教，灰常感谢。
/** 定义播放小孩声音的ACTION */
public static String SOUND_ACTION = "com.vtion.ym.box.sound";
XxxActivity.java Activity里面中的代码
View Code 1 @Override 2 public void onClick(View v) { 3 Intent intent = new Intent(Constant.SOUND_ACTION); 4 switch (v.getId()) { 5 case R.id.box_bottom1_lishi: 6 intent.putExtra("play_sound", 1); 7 break; 8 case R.id.box_bottom2_lishi: 9 intent.putExtra("play_sound", 2); 10 break; 11 case R.id.box_bottom3_lishi: 12 intent.putExtra("play_sound", 3); 13 break; 14 case R.id.box_bottom4_lishi: 15 intent.putExtra("play_sound", 4); 16 break; 17 case R.id.box_bottom5_lishi: 18 intent.putExtra("play_sound", 5); 19 break; 20 case R.id.box_bottom6_lishi: 21 intent.putExtra("play_sound", 6); 22 break; 23 case R.id.box_bottom7_lishi: 24 intent.putExtra("play_sound", 7); 25 break; 26 case R.id.box_bottom8_lishi: 27 intent.putExtra("play_sound", 8); 28 break; 29 case R.id.box_bottom9_lishi: 30 intent.putExtra("play_sound", 9); 31 break; 32 case R.id.box_bottom10_lishi: 33 intent.putExtra("play_sound", 10); 34 break; 35 case R.id.box_bottom11_lishi: 36 intent.putExtra("play_sound", 11); 37 break; 38 case R.id.box_bottom12_lishi: 39 intent.putExtra("play_sound", 12); 40 break; 41 case R.id.box_bottom13_lishi: 42 intent.putExtra("play_sound", 13); 43 break; 44 case R.id.box_bottom14_lishi: 45 intent.putExtra("play_sound", 14); 46 break; 47 default: 48 break; 49 } 50 startService(intent); 51 } 52 @Override 53 protected void onStop() { 54 Intent intent = new Intent(Constant.SOUND_ACTION); 55 stopService(intent); 56 super.onStop(); 57 }
XxxService.java Service里面中的代码
