我正在尝试为我的应用创建自定义建议。它运作良好，但现在我试图解决一个问题。我在AndroidManifest中设置了android:searchSuggestIntentAction="android.intent.action.VIEW"
<intent-filter>
<action android:name="android.intent.action.VIEW" />
</intent-filter> to Activity but even if I did this, it still sends default Intent - `ACTION_SEARCH`.
你有什么想法，问题出在哪里？
我的 AndroidManifest

mListView.setDividerHeight(0);

ParseQuery<Animal> squery = ParseQuery.getQuery(Animal.class);
squery.whereMatches("animal", query, "i");
squery.findInBackground(new FindCallback<Animal>() {

for (int i = 0; i < animals.size(); i++) {
mProgressBar = (ProgressBar) findViewById(R.id.search_loading_animals);
mProgressBar.setVisibility(View.INVISIBLE);
nAdapter.add(animals.get(i));
}
}
}
}); } }
我对任何答案或建议都很满意。我试图在很长一段时间内解决这个问题。

您不需要清单上的操作视图。把它放在searchable.xml中。
SELECT a.*
FROM a
WHERE a.col1 LIKE '%Empty%' OR a.col2 LIKE '%Empty%' OR ...
