I have a search menu item like this
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="@+id/action_search"
android:icon="@drawable/search_icon"
android:title="Search"
app:actionViewClass="android.widget.SearchView"
app:showAsAction="always|collapseActionView"/>
</menu>
I am inflating this and then setting up listeners for SearchView like this
override fun onCreateOptionsMenu(menu: Menu?): Boolean {
menuInflater.inflate(R.menu.search_menu_item, menu)
return true
}
override fun onPrepareOptionsMenu(menu: Menu?): Boolean {
val mSearchMenuItem = menu?.findItem(R.id.action_search)
mSearchMenuItem?.setOnActionExpandListener(object : MenuItem.OnActionExpandListener{
override fun onMenuItemActionExpand(p0: MenuItem?): Boolean {
return true
}
override fun onMenuItemActionCollapse(p0: MenuItem?): Boolean {
return true
}
})
searchView = mSearchMenuItem?.actionView as SearchView
searchView.setOnQueryTextListener(object : SearchView.OnQueryTextListener {
override fun onQueryTextSubmit(query: String): Boolean {
samSearchViewModel.searchData(query)
return false
}
override fun onQueryTextChange(newText: String): Boolean {
if (newText.length >= 3) {
samSearchViewModel.searchData(newText)
}
return false
}
})
searchView.setOnCloseListener(object : SearchView.OnCloseListener {
override fun onClose(): Boolean {
return false
}
})
return true
}
Then I am trying to display it using a SimpleCursorAdapter like this after getting data back from the server.
val strArr: Array<String?> = arrayOfNulls(t.datas?.size!!)
for(i in t.datas!!.indices){
strArr[i] = t.datas!![i]?.symbol
}
val searchManager = getSystemService(SEARCH_SERVICE) as SearchManager
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()))
val to = intArrayOf(android.R.id.text1)
searchView.setIconifiedByDefault(false)
searchView.setSuggestionsAdapter(SimpleCursorAdapter(this@MainActivity,android.R.layout.simple_list_item_1,null,strArr,to,CursorAdapter.FLAG_REGISTER_CONTENT_OBSERVER))
So what's happening is, I am able to expand the SearchView, type in it and then I am also getting data back from the server but then the search suggestions list is not popping up. It is just blank. What am I missing? Any help would be appreciated. Thanks
You may need to set Threshold .
AutoCompleteTextView searchAutoCompleteTextView = (AutoCompleteTextView) searchView.findViewById(android.support.v7.appcompat.R.id.search_src_text);
searchAutoCompleteTextView.setThreshold(3);
If you set Threshold to 3 that means it will start giving suggestions after typing first character
