If you are using SearchView then use for API below 21 android:queryBackground=”@android:color/transparent” you can use below code if you are using API 21 or more app:queryBackground=”@android:color/transparent”
You can achieve this using a theme: in styles.xml <style name=”AppSearchView” parent=”Widget.AppCompat.SearchView” > <item name=”android:textSize”>60sp</item> </style> And using a SearchView <android.support.v7.widget.SearchView android:id=”@+id/searchView” android:layout_width=”350dp” app:theme=”@style/AppSearchView” android:layout_height=”80dp” android:layout_marginTop=”15dp”/>
So I just had to do this for the v7 version and was dismayed to find that I cannot simply set the adapter with an ArrayAdapter. I did not want to use a stock AutoCompleteTextView (as the top commenter here does), because then you’re missing out on a number of snazzy features of SearchView, like … Read more
Place this inside your adapter: @Override public Filter getFilter(){ return new Filter(){ @Override protected FilterResults performFiltering(CharSequence constraint) { constraint = constraint.toString().toLowerCase(); FilterResults result = new FilterResults(); if (constraint != null && constraint.toString().length() > 0) { List<String> founded = new ArrayList<String>(); for(YourListItemType item: origData){ if(item.toString().toLowerCase().contains(constraint)){ founded.add(item); } } result.values = founded; result.count = founded.size(); }else { … Read more
Yes it is possible Your RecyclerView.Adapter can implement Filterable. After that you have to override Filter getFilter() method. You have to define your own filter as is shown in the code below: @Override public Filter getFilter() { return new YourFilterClass(); } YourFilterClass class YourFilterClass extends Filter { @Override protected FilterResults performFiltering(CharSequence constraint) { //Here you … Read more
Finally I found the solution. Changing namespace of actionViewClass from android:actionViewClass to app:actionViewClass Implementing android.support.v7.widget.SearchView.OnQueryTextListener interface for current activity. Directly use setOnQueryTextListener instead of SearchViewCompat.setOnQueryTextListener @Override public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.menu, menu); MenuItem searchItem = menu.findItem(R.id.action_search); SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem); if (searchView != null) { searchView.setOnQueryTextListener(this); } return super.onCreateOptionsMenu(menu); … Read more
Edit Change your android version on your designer preview into your current version depend on your Manifest. rendering problem caused your designer preview used higher API level than your current android API level. It should work Just change the api 22 to 21 in android xml layout
After a hard effort I found the answer myself. I use a function like this: fun colorsearch(a:String,charText: String):SpannableStringBuilder{ var l = 0 var b:ArrayList<Int> b = ArrayList() var w = 0 var i = 0 if (charText!=””){ label@ while (i < a.length) { var j=0 while (j<charText.length){ Log.v(“abc”, j.toString()) if (i == a.length) break@label while … Read more
It is actually quite easy to do this, if you are using android.support.v7 library. Step – 1 Declare a menu item <item android:id=”@+id/action_search” android:title=”Search” android:icon=”@drawable/abc_ic_search_api_mtrl_alpha” app:showAsAction=”ifRoom|collapseActionView” app:actionViewClass=”android.support.v7.widget.SearchView” /> Step – 2 Extend AppCompatActivity and in the onCreateOptionsMenu setup the SearchView. import android.support.v7.widget.SearchView; … public class YourActivity extends AppCompatActivity { … @Override public boolean onCreateOptionsMenu(Menu menu) … Read more
