Hello,

I found this 2 code in SOEN

Mode 1

InputMethodManager imm = (InputMethodManager) getActivity()
            .getSystemService(Context.INPUT_METHOD_SERVICE);

    if (imm.isAcceptingText()) {
        writeToLog("Software Keyboard was shown");
    } else {
        writeToLog("Software Keyboard was not shown");
    }

Mode 2

contentView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {

    Rect r = new Rect();
    contentView.getWindowVisibleDisplayFrame(r);
    int screenHeight = contentView.getRootView().getHeight();

    // r.bottom is the position above soft keypad or device button.
    // if keypad is shown, the r.bottom is smaller than that before.
    int keypadHeight = screenHeight - r.bottom;

    Log.d(TAG, "keypadHeight = " + keypadHeight);

    if (keypadHeight > screenHeight * 0.15) { // 0.15 ratio is perhaps enough to determine keypad height.
        // keyboard is opened
    }
    else {
        // keyboard is closed
    }
}
});
