How to hide soft keyboard on android 11?-CodePudding

I have an app using to scan barcode, so I want to hide the soft keyboard. My app worked fine on devices with android 7, 9... but when I installed it on device run android 11, the keyboard display when I scan.

I searched and tried many ways, like this in Manifest:

android:windowSoftInputMode="stateHidden"

Or this in activity:

InputMethodManager imm = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE); imm.hideSoftInputFromWindow(this.getCurrentFocus().getWindowToken(), 0);

None of these works. Does anyone have different solutions, please help. Thank you.

Here is two different methods for activity and fragment, Hope it might work for you.

// Method : Hide Keyboard
    @JvmStatic
    fun hideKeyboard(activity: Activity) {
        val imm = activity.getSystemService(Activity.INPUT_METHOD_SERVICE) as InputMethodManager
        var view = activity.currentFocus
        if (view == null) {
            view = View(activity)
        }
        imm.hideSoftInputFromWindow(view.windowToken, 0)
    }

    @JvmStatic
    fun hideKeyboardInFragment(context: Context?, view: View?/*Your EditText*/) {
        if (context != null && view != null) {
            val imm = context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
            imm.hideSoftInputFromWindow(view.windowToken, 0)
        }
    }

this is worked for me, please check

public static void hideKeyboard(Context context) {
    InputMethodManager inputManager = (InputMethodManager) context
            .getSystemService(Context.INPUT_METHOD_SERVICE);

    // check if no view has focus:
    View v = ((Activity) context).getCurrentFocus();
    if (v == null)
        return;
    inputManager.hideSoftInputFromWindow(v.getWindowToken(), 0);
}
