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

只需在manifest .xml中设置活动方向

android:screenOrientation="unspecified"

或限制为纵向方向

你也可以在super.onCreate(…)之前使用in Activity, in onCreate方法调用。

@Override
    protected void onCreate(Bundle savedInstanceState) {
        setOrientation(this);
        super.onCreate(savedInstanceState);
        setContentView(R.layout.your_xml_layout);
        //...
        //...
}

// Method 
public static void setOrientation(Activity context) {
   if (android.os.Build.VERSION.SDK_INT == Build.VERSION_CODES.O)
        context.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED);
      else
        context.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}

其他回答

如果activity是你自己创建的,你可以在activity中尝试:

@Override
public void setRequestedOrientation(int requestedOrientation) {
    try {
        super.setRequestedOrientation(requestedOrientation);
    } catch (IllegalStateException e) {
        // Only fullscreen activities can request orientation
        e.printStackTrace();
    }
}

这应该是最简单的解决方案。

我只在SDK 26(8.0.0)中遇到过这个问题,如果使用windowIsTranslucent 'true'并强制设置方向:

下面是解决方案:

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash);   

        // fixing portrait mode problem for SDK 26 if using windowIsTranslucent = true
        if (Build.VERSION.SDK_INT == 26) {
            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED);
        } else {
            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
        }        
    }



       <style name="SplashActivty" parent="AppTheme">
        <item name="android:windowIsTranslucent">true</item>
        <item name="android:windowBackground">@android:color/transparent</item>
        <item name="android:windowContentOverlay">@null</item>
        <item name="android:windowNoTitle">true</item>
    </style>



<!-- Splash screen -->
        <activity
            android:name="edu.aku.family_hifazat.activities.SplashActivity"
            android:label="@string/app_name"
            android:screenOrientation="unspecified"
            android:theme="@style/SplashActivty">

            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>

        </activity>

请检查你的活动样式,并确保如果你没有使用任何半透明相关的东西,改变样式为交替。这样我们就能解决这个问题。

android:theme="@android:style/Theme.Translucent.NoTitleBar.Fullscreen"
android:theme="@android:style/Theme.NoTitleBar.Fullscreen"

如果你还没有解决你的问题,就像这样在清单中注册广告活动:

<activity
android:name="com.google.android.gms.ads.AdActivity"
android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
tools:replace="android:theme"
 />

您还需要更新到sdk的最新版本。

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。
