Symbian获取输入法状态-优快云博客

本文介绍了一种使用MAknEditingStateIndicator来检测当前输入法状态的方法。通过检查不同类型的输入法指示器状态，如拼音、笔画、大小写等，可以在程序中根据不同输入法做出相应处理。

最好使用MAknEditingStateIndicator获取输入法状态。在KeyUp和KeyDown后，获取输入法状态。代码如下：

MAknEditingStateIndicator * ei = CAknEnv::Static()-> EditingStateIndicator() ;
if (!ei) return EUnknown;

CAknIndicatorContainer *ic = ei-> IndicatorContainer();
if (!ic) return EUnknown;

if(ic-> IndicatorState(S_uid(EAknNaviPaneEditorIndicatorPinyin) ))
{
//to do ... if input method = T9 (即拼音和笔画)
}
if(ic-> IndicatorState(S_uid(EAknNaviPaneEditorIndicatorStroke) ))
{
//to do ... if input method = T9 (即拼音和笔画)
}
else if(ic-> IndicatorState(S_uid(EAknNaviPaneEditorIndicatorLowerCase)))
{
//to do ... if input method = "abc ";
}
else if(ic-> IndicatorState(S_uid(EAknNaviPaneEditorIndicatorUpperCase)))
{
//to do ... if input method = "ABC ";
}
else if(ic-> IndicatorState(S_uid(EAknNaviPaneEditorIndicatorTextCase)))
{
//to do ... if input method = "Abc ";
}
else if(ic-> IndicatorState(S_uid(EAknNaviPaneEditorIndicatorNumberCase)))
{
//to do ... if input method = "123 ";
}
return EUnknown;

struct S_uid: public TUid
{
S_uid(int i)
{
iUid = i;
}
};

class MAknEditingStateIndicator
{
public:
virtual void SetState(TInt aState) = 0;
virtual CAknIndicatorContainer *IndicatorContainer() = 0;
};
