Android:将搜索查询返回到当前活动 [英] Android: Return search query to current activity

问题描述

我遵循了 http://developer.android 上描述的步骤.com/guide/topics/search/search-dialog.html 在我的记事本应用程序中实现搜索功能.

我的问题是，当我完成搜索时，会打开一个新活动来捕获我的搜索查询.但我真正想要的是，查询返回到当前活动而不是开始一个新活动.

这可能吗?

更新:

AndroidManifest.xml

<前><代码><activity android:name="MyNotepad";android:label=@string/app_name"><意图过滤器><action android:name="android.intent.action.MAIN";/><category android:name="android.intent.category.LAUNCHER";/><action android:name="android.intent.action.SEARCH></action></意图过滤器><meta-data android:resource="@xml/searchable";android:name="android.app.searchable"></meta-data></activity><activity android:name="Preferences";机器人:标签=首选项"；></活动>

searchable.xml

<前><代码><?xml version="1.0";编码=utf-8"?><可搜索的xmlns:android=http://schemas.android.com/apk/res/android"android:label="@string/app_name";android:hint="@string/search_hint"></可搜索的>

JAVA 代码

<前><代码>@覆盖public void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main_pad);意图意图 = getIntent();如果 (Intent.ACTION_SEARCH.equals(intent.getAction())) {字符串查询 = intent.getStringExtra(SearchManager.QUERY);Toast.makeText(getApplicationContext(), query, Toast.LENGTH_LONG).show();}}

<前><代码>@覆盖public boolean onOptionsItemSelected(MenuItem item){开关(item.getItemId()){案例 R.id.menuItemSearch:startSearch("", false, null, false);休息;}返回真；}

即使我使用手机上的搜索按钮也不起作用.因此我认为问题出在 AndroidManifest.xml

解决方案

在您的应用程序清单中，您需要将当前活动定义为可搜索活动.

<activity android:name="BrowseItems" android:label="@string/browseitems"android:launchMode="singleTop"><意图过滤器><action android:name="android.intent.action.SEARCH"/></意图过滤器><meta-data android:name="android.app.searchable"android:resource="@xml/itemsearchable"/></活动>

然后您使用以下代码，该代码来自 http://developer.android.com/guide/topics/search/search-dialog.html#LifeCycle

@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.search);handleIntent(getIntent());}@覆盖受保护的无效 onNewIntent(意图意图){设置意图(意图)；处理意图(意图)；}私人无效handleIntent(意图意图){如果 (Intent.ACTION_SEARCH.equals(intent.getAction())) {字符串查询 = intent.getStringExtra(SearchManager.QUERY);//使用字符串做工作}}

然后您可以使用该字符串重新加载您的活动，如果它是一个列表活动，您可以调用您用来加载数据的代码并在其中使用该字符串.

I followed the steps described on http://developer.android.com/guide/topics/search/search-dialog.html to implement a search feature in my notepad application.

My problem is, that when I finish the search a new activity opens capturing my search query. But what I really want, is the query returned to the current activity instead of starting a new one.

Is this possible?

UPDATE:

AndroidManifest.xml

<activity android:name="MyNotepad"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
                <action android:name="android.intent.action.SEARCH"></action>
            </intent-filter>
            <meta-data android:resource="@xml/searchable" android:name="android.app.searchable"></meta-data>
        </activity><activity android:name="Preferences" android:label="Preferences" >
</activity>

searchable.xml

<?xml version="1.0" encoding="utf-8"?>
<searchable
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:label="@string/app_name"
  android:hint="@string/search_hint">
</searchable>

JAVA-code

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main_pad);
    Intent intent = getIntent();
    if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
        String query = intent.getStringExtra(SearchManager.QUERY);
        Toast.makeText(getApplicationContext(), query, Toast.LENGTH_LONG).show();
    }
}

@Override
public boolean onOptionsItemSelected(MenuItem item)
{
    switch(item.getItemId())
    {
        case R.id.menuItemSearch:
            startSearch("", false, null, false);
    break;
    }
    return true;
}

Even if I use the search-button on the phone it doesn't work. I therefor believe that the problem is in the AndroidManifest.xml

解决方案

In your Application Manifest you need to define the current activity as a searchable activity.

<activity android:name="BrowseItems" android:label="@string/browseitems"
            android:launchMode="singleTop">
            <intent-filter>
                <action android:name="android.intent.action.SEARCH" />
            </intent-filter>
            <meta-data android:name="android.app.searchable"
                android:resource="@xml/itemsearchable" />
</activity>

You then use the following code, which is from http://developer.android.com/guide/topics/search/search-dialog.html#LifeCycle

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.search);
    handleIntent(getIntent());
}

@Override
protected void onNewIntent(Intent intent) {
    setIntent(intent);
    handleIntent(intent);
}

private void handleIntent(Intent intent) {
    if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
      String query = intent.getStringExtra(SearchManager.QUERY);
      // Do work using string
    }
}

You can then use the string to reload your activity, if its a list activity you can call your code that you use to load data and use the string in that.
