Hari: this is exactly what I'd like to do. The EditText will be used
to input a specific value with only certain units allowed. So I have
extended android.inputmethodservice.Keyboard and use it together with
android.inputmethodservice.KeyboardView so that the keyboard only
shows the characters that make sense in this specific context. So far
the solution I have come up with is to get a handle on the
InputMethodManager (imm) and add OnFocus-, OnClick- and
OnTouchListener's for the EditText which all call the following helper
method:
private boolean makeActive(View v) {
imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
EditText e = (EditText) v;
int iType = e.getInputType();
e.setInputType(InputType.TYPE_NULL);
e.requestFocus();
showKb();
e.setInputType(iType);
e.setSelection(e.getText().length());
return true;
}
protected void showKb() {
this.kbView.setVisibility(View.VISIBLE);
Here kbView is the KeyboardView connected to my custom keyboard. So
far this works - but it's not very elegant nor am I sure it is an
optimal solution. But as said, it's the only thing that works for me
so far. I'd be glad to receive some comments on your behalf.
