how to get Activity's windowToken without view?

Question

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?

`InputMethodManager inputManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);` `inputManager.hideSoftInputFromWindow(findViewById(android.R.id.content).getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);` — Pratik Butani, Sep 23 '13 at 07:19

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).getWind‌owToken()

Surely you can use:

getContentView().getWindowToken()

or you can refer to SO Quest

Solved according Hanry's suggestion: findViewById(android.R.id.content).getWindowToken() – David Guo Oct 18 '11 at 00:59

There is no getContentView() method. Use findViewById(android.R.id.content).getWindowToken() instead. – mhsmith Oct 21 '15 at 17:21

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

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;
}

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

getWindow().getAttributes().token

From the docs `This will usually be filled in for you.`. This is strange :) – Vlad Aug 21 '20 at 13:25

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

 android:windowSoftInputMode="stateHidden"
