就是这样，您应该创建一个辅助方法，然后通过传递适用的上下文来调用它。在您想要的事件发生后调用此方法。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);}
