我最近创建了搜索建议,但现在我面临一个奇怪的问题。在searchable.xml中,我设置了android:searchSuggestIntentAction="android.intent.action.VIEW"
,而在Manifest中我设置了
<intent-filter>
<action android:name="android.intent.action.VIEW" />
</intent-filter> to a activity, which I want to open when the click on suggestion is performed.
结果是它会打开另一个活动 - 活动,我显示结果,提交查询时以及放置此意图过滤器的位置<intent-filter> ...SEARCH /> </intent-filter>
点击建议时,有没有办法,如何打开不同的活动?
