傳入目前畫面位置即可~

Java：

public static void hideKeyboard(Activity activity) {
    InputMethodManager imm = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
    //Find the currently focused view, so we can grab the correct window token from it.
    View view = activity.getCurrentFocus();
    //If no view currently has focus, create a new one, just so we can grab a window token from it
    if (view == null) {
        view = new View(activity);
    }
    imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}

 

Kotlin：

import android.app.Activity
import android.view.View
import android.view.inputmethod.InputMethodManager
import androidx.appcompat.app.AppCompatActivity

        fun hideKeyboard(activity: Activity){
            val imm: InputMethodManager = activity.getSystemService(AppCompatActivity.INPUT_METHOD_SERVICE) as InputMethodManager
            //Find the currently focused view, so we can grab the correct window token from it.
            var view = activity.currentFocus
            //If no view currently has focus, create a new one, just so we can grab a window token from it
            if (view == null) {
                view = View(activity)
            }
            imm.hideSoftInputFromWindow(view.windowToken, 0)
        }
    }
