how to get Activity's windowToken without view?

Now, I try to hide the softkeyboard when user touch outside the keyboard:

((InputMethodManager) getSystemService(INPUT_METHOD_SERVICE))
.hideSoftInputFromWindow(editView.getWindowToken(),
InputMethodManager.HIDE_NOT_ALWAYS);

I want put the logic in my base activity class, so if it is possible to getWindowToken without View?

In kotlin:

val imm  = getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
imm.hideSoftInputFromWindow(window.attributes.token, 0)

Or, If you have a view:

imm.hideSoftInputFromWindow(view.windowToken, 0)

You could just get the token from the WindowManager.LayoutParams of the window directly

getWindow().getAttributes().token

Simply use getWindow().getDecorView().getWindowToken()

You can try this on your manifest file activity tag to hide keyboard.

 android:windowSoftInputMode="stateHidden"

public static final String M_TOKEN = "mToken";

@Nullable
protected IBinder getToken(Activity activity) {
    try {
        Field mTokenField = Activity.class.getDeclaredField(M_TOKEN);
        mTokenField.setAccessible(true);
        IBinder mToken = (IBinder) mTokenField.get(activity);
        return mToken;
    } catch (NoSuchFieldException e) {
        // handle 
    } catch (IllegalAccessException e) {
       // handle
    }
    return null;
}

I faced exactly the same problem, while writing OnPageChangeListener within an Activity. You can use one of these solutions. Either:

getWindow().getDecorView().getRootView().getWindowToken()

or:

findViewById(android.R.id.content).getWind‌​owToken()

Surely you can use:

getContentView().getWindowToken()

or you can refer to SO Quest
