睡眠助手功能实现

这篇文章（）上纪录了睡眠助手的UI的实现。现在纪录下睡眠助手功能的实现

这篇文章（Android应用--->睡眠助手）的时间和开关设置是单独的按钮实现的，后来发现这样设计不合理，就把时间设置改成了只有在选中了开关设置的开之后才可以设置时间。整合代码如下：

//设置开关按钮事件监听        class SetOnOffListener implements OnClickListener {              AlertDialog singleDialog = null ;           @Override           public void onClick(View v) {                              final String[] strs = new String[]{"开","关"};                              singleDialog = new AlertDialog.Builder(HelperMain.this)                               .setTitle("设置开关")                               .setIcon(Android.R.drawable.ic_dialog_info)                               .setSingleChoiceItems(strs, 0,                                       new DialogInterface.OnClickListener() {                                                                                      @Override                                           public void onClick(DialogInterface dialog, int which) {                                               if(strs[which].equals("开")) {                                                   helper = true ;                                                   setTime();                                                   //openHelper();                                                                                                   } else if(strs[which].equals("关")){                                                   close();                                                   helper = false ;                                                   onOffShow.setText("关");                                                   Toast.makeText(HelperMain.this, "助手已关", Toast.LENGTH_SHORT).show();                                               }                                               singleDialog.dismiss();                                               SharedPreferences uiState = getPreferences(0);                                               SharedPreferences.Editor editor = uiState.edit();                                               editor.putBoolean("on_off", helper);                                               editor.commit();                                           }                                       })                                       .create();               singleDialog.show();           }                  }
