当对话框关闭时，默认键盘仍然可见？

Question

问题

我想使用 OTP 验证更改手机号码。我在用户个人资料屏幕上有一个更改按钮。单击更改按钮时，我正在打开一个对话框。一旦对话框打开，用户正在输入他的新联系号码并按下对话框的重新发送 otp 按钮，然后对话框将关闭并且键盘也应该隐藏。但是，键盘并没有隐藏。 change_no_dialog-box 关闭后的一件事，一旦用户输入 OTP 并再次按下提交按钮，我将再显示一个输入 OTP 对话框，同样的问题是键盘没有隐藏。

这是我尝试过的

编辑对话框上的文本

        <android.support.design.widget.TextInputLayout
            android:layout_marginTop="36dp"
            android:theme="@style/TextLabel"
            android:id="@+id/no_layout"
            android:layout_marginLeft="24dp"
            android:layout_marginRight="24dp"
            android:layout_width="match_parent"
            android:layout_height="match_parent">

            <EditText
                android:paddingLeft="8dp"
                android:id="@+id/dialog_box_mobile"
                android:layout_width="match_parent"
                android:layout_height="60dp"
                android:inputType="number"
                android:imeOptions="actionDone"
                android:singleLine="true"
                android:textColorHint="@color/navigation_header"
                android:hint="@string/mobno"
                android:textSize="@dimen/sisteen"
                android:maxLength="10"/>

        </android.support.design.widget.TextInputLayout>

点击重新发送 otp 按钮

  if (v.getId() == R.id.resend_otp_btn) {

            if (dialog_box_mobile.getText().toString().equals(user_mobile_no)) {
                hideKeyboard(EditProfileActivity.this);
                dialog.dismiss();
                bottomSnackbarMessage("It looks like same number !");
                // Toast.makeText(EditProfileActivity.this, "It looks like same number!", Toast.LENGTH_SHORT).show();

            } else {

                if (dialog_box_mobile.getText().length() != 0) {
                    if (dialog_box_mobile.getText().toString().length() < 10) {

                        dialog_box_mobile.setError("Invalid phone number !");
                        resend_otp_btn.setClickable(true);

                    } else {
                        if (CheckNetwork.isConnected()) {
                            resend_otp_btn.setClickable(false);
                            dialog.dismiss();
                            startPhoneNumberVerification(dialog_box_mobile.getText().toString());
                        } else {
                            dialog.dismiss();
                            bottomSnackbar();
                        }

                    }


                } else if (dialog_box_mobile.getText().toString().equalsIgnoreCase("")) {
                    dialog_box_mobile.setError("Mobile number required");
                    resend_otp_btn.setClickable(true);

                }


            }


        }

键盘隐藏方法

  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);
    }

在 mainifest 和每个 Activity 布局上添加这个

 android:windowSoftInputMode="stateHidden"

请看截图

试试这个：

        public static void hideKeyboard(EditText edt) {
            InputMethodManager imm = (InputMethodManager) 
                 edt.getContext().getSystemService(Activity.INPUT_METHOD_SERVICE);              
            imm.hideSoftInputFromWindow(et.getWindowToken(), 0);
        }

还在下方添加关闭侦听器：

           dialogBox.setOnDismissListener(new DialogInterface.OnDismissListener() {
        @Override
        public void onDismiss(DialogInterface dialogInterface) {
                   hideKeyBoard(editText);
            dialogBox.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);

        }
    });
