How to force to show and hide virtual Keyboard if no hardware keyboard is available?

Question

How can I detect that the telephone does not have hardware keyboard and only in that case to force showing the virtual one? And how can I hide it?

I tried putting the focus like this but it doesn't work:

View exampleView = (View)findViewById(R.id.exampleBox);
exampleView.requestFocus(); 

If I force like this the virtual keyboard, the keyboard will appear also when a hardware keyboard is available, which doesn't make sense.

InputMethodManager inputMgr = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
inputMgr.toggleSoftInput(0, 0);

And last but not least, how can I show directly the numerical or phone keyboard? (Not the normal keyboard)

Any idea?

Thanks!

我会说使用Configuration类hardKeyboardHidden来查看硬键盘是否已经关闭，如果没有，则打开软键盘
