我在 Android 8.0 Oreo java.lang.IllegalStateException 中从通讯录中检索联系人时遇到问题:只有全屏不透明 Activity 才能请求方向

我正在尝试从电话联系簿中获取我的 Activity 中的联系人，它非常适合 Lollipop 、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");
        }
}

最佳答案

在 android Oreo (API 26) 中，您不能更改具有以下样式的 Activity 的方向

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

或

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

你有几种方法可以解决这个问题:

1)您只需删除上面的行(或将其设置为false)，您的应用就可以正常运行。

2) 或者您可以先从该 Activity 的 list 中删除下面的行

android:screenOrientation="portrait"

然后您必须添加这一行到您的 Activity 中(在 onCreate() 中)

'>=' change to '!=' thanks to Entreco comment

    //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 values-v26 文件夹中创建新的 styles.xml 并将其添加到您的 style.xml。 (感谢 AbdelHady 评论)

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