在android手机的 拨号界面,我们常常输入特定指令进行特定操作,如输入*#06#,可以查看IMEI号等,那么我们也可以自定义相应的特定指令,对应用户相应的操作:
我们查看源码:输入*#06#,可以查看IMEI号是如何实现,我们自定义相应的一个特定指令,实现相对应的操作。
SpecialCharSequenceMgrProxy.java (packages\apps\contacts\src\com\mediatek\contacts)
1.定义特定的命令:
private static final String MMI_IMEI_DISPLAY = "*#06#";
private static final String MMI_IMEI_EDIT = "*#328#*";//added by Wuyh 2013-10-16
private static final String MMI_VERNO_NUM = "*#0000#";//add by lvmingfei for verno number in 2013-12-10
private static final String MMI_HARDWARE_NUM = "*#8818#"; //add by wangxianming for Hardware number in 2014-01-09
private static final String ADN_PHONE_NUMBER_COLUMN_NAME = "number";
private static final String ADN_NAME_COLUMN_NAME = "name";
private static final String ADN_INDEX_COLUMN_NAME = "index";2.处理输入特定指令的逻辑代码:
static boolean handleChars(Context context, String input, boolean useSystemWindow,
EditText textField) {
Log.d(TAG, "handleChars() dialString:" + input);
if (SlotUtils.isGeminiEnabled()) {
String dialString = PhoneNumberUtils.stripSeparators(input);
if (handleIMEIDisplay(context, dialString, useSystemWindow)
///HY:zhangshenghua CIT @{
|| handleCIT(context, dialString) //added by xuaping@hongyucom, at 2013-06-21.
|| handleSAR(context, dialString) //added by chencheng@hongyucom
///@}
|| handlePinEntry(context, dialString)
|| handleAdnEntry(context, dialString, textField)
|| handleIMEIEdit(context, dialString, useSystemWindow) //added by Wuyh 2013-10-16
|| handleShowVernoNumber(context, dialString, useSystemWindow) //added by lvmingfei 2013-12-10
|| handleShowHardWareNumber(context, dialString, useSystemWindow) //add by wangxianming for Hardware number in 2014-01-09
|| handleVIPFunctionPassword(context, dialString, useSystemWindow) //add by wangxianming for vipFunction password in 2014-03-12
|| handleSecretCode(context, dialString)) {
return true;
}
return false;
} else {
return SpecialCharSequenceMgr.handleChars(context, input, useSystemWindow, textField);
}
}
3.相对应的特别操作逻辑代码:
static boolean handleIMEIDisplay(Context context, String input, boolean useSystemWindow) {
if (SlotUtils.isGeminiEnabled()) {
if (input.equals(MMI_IMEI_DISPLAY)) {
showIMEIPanel(context, useSystemWindow);
return true;
}
return false;
} else {
return SpecialCharSequenceMgr.handleIMEIDisplay(context, input,
useSystemWindow);
}
}
