我正在开发一个软键盘并且运行良好,但我不知道如何为长按键自定义弹出式布局.

我的KeyboardView:

<?xml version="1.0" encoding="UTF-8"?>
<android.inputmethodservice.KeyboardView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/keyboard"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:keyPreviewLayout="@layout/preview"
android:keyBackground="@drawable/key_selector"
android:shadowRadius="0.0"
android:keyTextColor="#000000"
/>

我的键盘布局:

<?xml version="1.0" encoding="utf-8"?>
<Keyboard xmlns:android="http://schemas.android.com/apk/res/android"
android:keyWidth="10%p"
android:keyHeight="10%p">

<Row android:verticalGap="1%p"  android:horizontalGap="0.5%p" android:keyHeight="8%p" android:keyWidth="9.6%p">
    <Key android:codes="113"    android:keyLabel="q" />
    <Key android:codes="119"    android:keyLabel="w" />
    <Key android:codes="101"    android:keyLabel="e"  
        />
    <Key android:codes="114"    android:keyLabel="r" />
    <Key android:codes="116"    android:keyLabel="t" />
    <Key android:codes="121"    android:keyLabel="y"
         android:popupKeyboard="@xml/keyboard_popup" android:popupCharacters="yýÿ"/>
    <Key android:codes="117"    android:keyLabel="u"
         android:popupKeyboard="@xml/keyboard_popup" android:popupCharacters="uúù?ûü"/>
    <Key android:codes="105"    android:keyLabel="i" 
         android:popupKeyboard="@xml/keyboard_popup" android:popupCharacters="iíì?îï"/>
    <Key android:codes="111"    android:keyLabel="o" 
         android:popupKeyboard="@xml/keyboard_popup" android:popupCharacters="oóò&#245;ôö" />
    <Key android:codes="112"    android:keyLabel="p" />
</Row>
<Row android:verticalGap="1%p" android:horizontalGap="0.5%p" android:keyHeight="8%p" android:keyWidth="9.6%p"> …

我正在尝试使用https://developers.google.com/cloud-messaging/android/client来实现GCM for android .

Created configuration file and placed under project/src..Added all the permissions in manifest file..
still onHandleIntent() method is not getting called, and token is not generated..

My intentservice file:

public class RegistrationIntentService extends IntentService {

    private static final String TAG = "RegIntentService";
    private static final String[] TOPICS = {"global"};

    public RegistrationIntentService() {
        super(TAG);
    }

    @Override
    public void onDestroy() {
        Log.d(TAG, "onDestroy()");
        super.onDestroy();
    }

    @Override
    protected void onHandleIntent(Intent intent) {
        SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(this);

        try { …

我有一个简单的tableViewController，一个searchBar带范围和一个navigationBar.

当我点击我的searchBar我看到我的范围和所有工作。然后我单击一行并转到我DetailPage的搜索栏并没有隐藏（我不知道为什么）。

所以我点击取消，然后我回到我的tableView. 当我返回到我的 tableView 时，我SearchBar和我的NavigationBar.

这是我的代码：

      self.resultSearchController = ({
            let controller = UISearchController(searchResultsController: nil)
            controller.searchResultsUpdater = self
            controller.hidesNavigationBarDuringPresentation = true
            controller.dimsBackgroundDuringPresentation = false
            controller.searchBar.sizeToFit()
            controller.searchBar.scopeButtonTitles = ["Title", "Author", "Location", "Price", "User"]
            self.tableView.tableHeaderView = controller.searchBar
            return controller
        })()

 func updateSearchResults(for searchController: UISearchController)
    {
        let scopes = resultSearchController.searchBar.scopeButtonTitles
        let currentScope = scopes![resultSearchController.searchBar.selectedScopeButtonIndex] as String
        filterContentForSearchText(searchText: searchController.searchBar.text!, scope: currentScope)
    }
