小编Rod*_*rta的帖子

您好我正在尝试实施SearchView,就像我们在Gmail中一样.

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    if (!mNavigationDrawerFragment.isDrawerOpen()) {
        getMenuInflater().inflate(R.menu.main, menu);

        searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
        searchView = (SearchView) menu.findItem(R.id.action_search).getActionView();
        searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));


        restoreActionBar();
        return true;
    }

    return super.onCreateOptionsMenu(menu);
}

searchView对象为null

表现:

    <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.dgp"
    android:versionCode="1"
    android:versionName="1.0" >

        android:minSdkVersion="18"
        android:targetSdkVersion="21" />

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/logo"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <meta-data
            android:name="android.app.default_searchable"
            android:value=".GameSearchActivity" />

        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".GameInfoActivity"
            android:label="@string/title_activity_game_info" >
            <meta-data
                android:name="android.support.PARENT_ACTIVITY"
                android:value=".MainActivity" /> …

我有一个GET方法的例子,它生成一个Randon INT并发送回客户端

@GetMapping
public Flux<String> search() {
    return Flux.create(fluxSink -> {

            Random r = new Random();
            int n;
            for (int i = 0; i < 10; i++) {
                n= r.nextInt(1000);
                System.out.println("Creating:"+n);
                fluxSink.next(String.valueOf(n));

                try {
                    Thread.sleep(2000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
            fluxSink.complete();


    });
}

卷曲:

curl -v -H"Accept:text/event-stream"-X GET'http :// localhost:8080/stream

使用CURL命令使用此代码,我只能在fluxSink.complete发生时查看客户端中的数字.

现在如果我将我的代码更改为:

@GetMapping
public Flux<String> search() {
    return Flux.create(fluxSink -> {
        Thread t = new Thread(() -> {
            Random r = new Random();
            int n;
            for (int …
