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，我打开一个对话框。一旦对话框打开，用户正在键入新的联系人号码并按下重新发送对话框的otp按钮，然后对话框将被关闭，键盘也应该隐藏。但是，键盘并没有隐藏。改变change_no_dialog-box之后的一件事我会再次显示一个用于输入OTP的对话框，一旦用户进入OTP并再次按下提交按钮，同样的问题就会出现键盘没有隐藏。

这里我尝试了

对话框上的Edittext

        <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和每个活动布局上添加

 android:windowSoftInputMode="stateHidden"

请看ScreenShot

On change button clicked opening dialog

Here i want to hide keyboard while dialog box is dismiss

Answer 1

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);
        }

另外在下面添加dismiss listener：

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

        }
    });

因为您的焦点视图在对话框上。您需要从视图中删除键盘。请使用以下代码。

{
            "_id" : ObjectId("5a27b609e101b6092b4ebf91"),
            "city" : "Mumbai",
            "detail" : [
                {
                    "type" : "One",
                    "name" : "Some name",
                    "_id" : ObjectId("5a27b609e101b6092b4ebf92"),
                    "numbers" : [
                        "72598xxx78",
                        "81301xxx88",
                        "83302xxx30",
                        "84309xxx43",
                        "85309xxx77",
                        "86309xxx61",
                        "87270xxx88",
                        "85272xxx36",
                        "88272xxx23",
                        "85276xxx01"
                    ]
                },
                {
                    "name" : "Some name",
                    "type" : "two",
                    "_id" : ObjectId("5a28e954d4f5a30527d92a32"),
                    "contact" : [
                        "72598xxx78",
                        "81301xxx88",
                        "83302xxx30",
                        "84309xxx43",
                        "85309xxx77",
                        "86309xxx61",
                        "87270xxx88",
                        "85272xxx36",
                        "88272xxx23",
                        "85276xxx01"
                    ]
                },
    ]
    }

在解除对话之前调用它。

 public static void hideSoftKeyboard(Activity activity, View view) {
    if (view != null) {
        InputMethodManager inputMethodManager = (InputMethodManager) activity
                .getSystemService(Activity.INPUT_METHOD_SERVICE);
        if (inputMethodManager.isActive()) {
            System.out.println("Keyboard hiden");
            inputMethodManager.hideSoftInputFromWindow(view
                    .getWindowToken(), 0);
        } else {
            System.out.println("Keyboard not visible");
        }
    }
}

当Dialog-box被取消时，默认键盘仍然可见？
