Android - SearchView setFilters and color of the text

I am trying to create a SearchView and programatically change textcolor and add filters e.g. max length.

SearchView search = findViewById(R.id.searchView1);
TextView textView = search.findViewById(R.id.search_src_text);
    textView.setTextColor(Color.rgb(0, 0, 0));
    textView.setFilters(new InputFilter[]{new InputFilter.LengthFilter(15)});

This way it says Cannot resolve symbol 'search_src_text'

Then I tried:

SearchView search = findViewById(R.id.searchView1);
int id = search.getContext().getResources().getIdentifier("android:id/search_src_text", null, null);
        TextView textView = search.findViewById(id);
        textView.setTextColor(Color.rgb(0, 0, 0));
        textView.setFilters(new InputFilter[]{new InputFilter.LengthFilter(15)});

In this case there is No error, but only warning, that Use of getIdentifier is discouraged

My Searchview in xml:

<SearchView
    android:id="@+id/searchView1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_margin="20dp"
    android:background="@drawable/searchfield"
     />

Is there any other way to do the same thing with SearchView without any warnings and errors?

Solution

I would suggest to replace the SearchView with androidx.appcompat.widget.SearchView and use

val searchView: SearchView = findViewById(R.id.searchView1)
val textView: TextView = searchView.findViewById(androidx.appcompat.R.id.search_src_text)

Here is some information on Why to use androidX

Sample gradle update

implementation("androidx.compose.ui:ui")
implementation("androidx.compose.ui:ui-graphics")
implementation("androidx.compose.ui:ui-tooling-preview")
implementation("androidx.compose.material3:material3")

val navVersion = "2.7.6"

implementation("androidx.appcompat:appcompat:1.6.1")
implementation("com.google.android.material:material:1.11.0")
