我在Android 8.0 Oreo java.lang.IllegalState中从通讯录中检索联系人时遇到问题：只有全屏不透明活动才能请求定向

我正在尝试从电话联系簿中获取我活动的联系，它非常适合棒棒糖，棉花糖，牛轧糖等，但它会给我这样的奥利奥错误，请帮助我。我的代码在下面。

演示代码：-

private void loadContacts() {
            contactAsync = new ContactLoaderAsync();
            contactAsync.execute();
        }

        private class ContactLoaderAsync extends AsyncTask<Void, Void, Void> {
            private Cursor numCursor;

            @Override
            protected void onPreExecute() {
                super.onPreExecute();
                Uri numContacts = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
                String[] numProjection = new String[]{ContactsContract.CommonDataKinds.Phone.CONTACT_ID, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME, ContactsContract.CommonDataKinds.Phone.NUMBER, ContactsContract.CommonDataKinds.Phone.TYPE};
                if (android.os.Build.VERSION.SDK_INT < 11) {
                    numCursor = InviteByContactActivity.this.managedQuery(numContacts, numProjection, null, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " COLLATE NOCASE ASC");
                } else {
                    CursorLoader cursorLoader = new CursorLoader(InviteByContactActivity.this, numContacts, numProjection, null, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " COLLATE NOCASE ASC");
                    numCursor = cursorLoader.loadInBackground();
                }

            }

            @Override
            protected Void doInBackground(Void... params) {
                if (numCursor.moveToFirst()) {
                    try {
                        final int contactIdIndex = numCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID);
                        final int displayNameIndex = numCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
                        final int numberIndex = numCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
                        final int typeIndex = numCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE);
                        String displayName, number, type;
                        do {
                            displayName = numCursor.getString(displayNameIndex);
                            number = numCursor.getString(numberIndex);
                            type = getContactTypeString(numCursor.getString(typeIndex), true);
                            final ContactModel contact = new ContactModel(displayName, type, number);
                            phoneNumber = number.replaceAll(" ", "").replaceAll("\\(", "").replaceAll("\\)", "").replaceAll("-", "");

                            if (phoneNumber != null || displayName != null) {
                                contacts.add(phoneNumber);
                                contactsName.add(displayName);
                                contactsChecked.add(false);

                                filterdNames.add(phoneNumber);
                                filterdContactNames.add(displayName);
                                filterdCheckedNames.add(false);
                            }
                        } while (numCursor.moveToNext());
                    } finally {
                        numCursor.close();
                    }
                }


                Collections.sort(contacts, new Comparator<String>() {
                    @Override
                    public int compare(String lhs, String rhs) {
                        return lhs.compareToIgnoreCase(rhs);
                    }
                });

                InviteByContactActivity.this.runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        mContactAdapter.notifyDataSetChanged();
                    }
                });

                return null;
            }
        }

        private String getContactTypeString(String typeNum, boolean isPhone) {
            String type = PHONE_TYPES.get(typeNum);
            if (type == null)
                return "other";
            return type;
        }

        static HashMap<String, String> PHONE_TYPES = new HashMap<String, String>();

        static {
            PHONE_TYPES.put(ContactsContract.CommonDataKinds.Phone.TYPE_HOME + "", "home");
            PHONE_TYPES.put(ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE + "", "mobile");
            PHONE_TYPES.put(ContactsContract.CommonDataKinds.Phone.TYPE_WORK + "", "work");
        }
}

答案 1

在 android Oreo （API 26）中，您无法更改样式低于行的活动的方向

 <item name="android:windowIsTranslucent">true</item>

或

 <item name="android:windowIsFloating">true</item>

您有几种方法可以解决此问题：

1）您只需删除上面的行（或将其转换为假），您的应用程序就可以正常工作。

2）或者您可以先从该活动的清单中删除下面的行

android:screenOrientation="portrait"

然后，您必须将此行添加到您的活动中（在 onCreate（）中）

“>=” 更改为“！=” 感谢 Entreco 评论

    //android O fix bug orientation
    if (android.os.Build.VERSION.SDK_INT != Build.VERSION_CODES.O) {
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
    }

3）您可以在文件夹中创建新的文件夹并将其添加到您的.（感谢阿卜杜勒哈迪的评论）styles.xmlvalues-v26style.xml

 <item name="android:windowIsTranslucent">false</item>
 <item name="android:windowIsFloating">false</item>

答案 2

在 Android O 及更高版本中，当您设置

 android:screenOrientation="portrait"

在清单中。

删除该行并使用

 setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

在您的活动中。

这将解决您的问题。
