illegalstateexception:只有全屏不透明活动可以请求方向

我在Android 8.0 Oreo的联系人簿中检索联系人时遇到了这个问题:只有全屏不透明的活动才能请求方向

我正在尝试从电话联系簿中获取我的活动中的联系人，它对棒棒糖、棉花糖、牛轧糖等都非常有效，但它会给我奥利奥这样的错误，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");
        }
}

当前回答

试着删除主题中的线条:

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

and

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

在此之后，添加android:screenOrientation="portrait"在你的活动。

其他回答

这发生在27之后，使用targetSdkVersion 26替换，等待谷歌修复它

我解决了这个问题，删除android:screenOrientation=“肖像”，并添加以下代码到我的onCreate

if (Build.VERSION.SDK_INT < Build.VERSION_CODES.O) {
            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}

而我的主题属性是

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

它似乎当目标sdk是馅饼(api级别28.0)和windowIsTranslucent是真的

< name = android: windowIsTranslucent >项目真正的< - >项目

你试着获得方向。问题来自android oreo 8.0 (api级别26)，有两种方法来解决这个问题

移除方向或者将windowIsTranslucent设置为false

如果你在manifest中像这样设置方向

android:screenOrientation="portrait"

或在这样的活动课上

 setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

从这两个地方移开。

并且当你将windowIsTranslucent设置为true时，它会从父activity中获取方向。

如果使用全屏透明活动，则不需要在活动上指定方向锁。它将接受父活动的配置设置。如果父活动在manifest中有:

android：screenOrientation=“portrait”

你的半透明活动将有相同的方向锁定:纵向。

如果你必须使用setRequestedOrientation()，除了牺牲Android 8.0上的windowIsTranslucent属性外别无他法

值\styles.xml为API级别25- (<8.0)

<style name="Base.Theme.DesignDemo" parent="Base.Theme.AppCompat.Light">
        ...
        <item name="android:windowIsTranslucent">true</item>
        ...
    </style>

Values-v26 \styles.xml用于API级别26 (=8.0)

<style name="Base.Theme.DesignDemo" parent="Base.Theme.AppCompat.Light">
    ...
    <!-- android 8.0(api26)，Only fullscreen opaque activities can request orientation -->
    <item name="android:windowIsTranslucent">false</item>
    ...
</style>

v27\styles.xml for API level 27+ (>8.0)

<style name="Base.Theme.DesignDemo" parent="Base.Theme.AppCompat.Light">
    ...
    <item name="android:windowIsTranslucent">true</item>
    ...
</style>
