android - 按下工具栏后退箭头时键盘保持打开状态

Question

我正在执行以下代码:-

 @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // handle arrow click here
        if (item.getItemId() == android.R.id.home) {

            finish();
            overridePendingTransition(R.transition.right_in, R.transition.right_out);


        }
        return super.onOptionsItemSelected(item);
    }

在这种情况下，当我的键盘打开并且我按工具栏后退箭头时，键盘保持打开状态并且 Activity 完成。我尝试通过调用下面的方法在暂停()时强制隐藏键盘，但在转换时看起来不太好:-

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);

    }

尝试在工具栏后退按钮中放入以下代码:

//Hide keyboard when button was clicked.
        InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);
        inputMethodManager.hideSoftInputFromWindow(v.getWindowToken(), 0);

像这样:

 @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // handle arrow click here
        if (item.getItemId() == android.R.id.home) {

            finish();
            overridePendingTransition(R.transition.right_in, R.transition.right_out);


        }
    //Hide keyboard when button was clicked.
        InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);
        inputMethodManager.hideSoftInputFromWindow(v.getWindowToken(), 0);
        return super.onOptionsItemSelected(item);
    }
