How to change hint text size for AndroidX SearchView?

Question

I have tried these approaches which did not work -

Approach 1:

    val searchView = binding.mSearchView
    val linearLayout1 = searchView.getChildAt(0) as LinearLayout
    val linearLayout2 = linearLayout1.getChildAt(2) as LinearLayout
    val linearLayout3 = linearLayout2.getChildAt(1) as LinearLayout
    val autoComplete = linearLayout3.getChildAt(0) as AutoCompleteTextView
    autoComplete.textSize = 12f

Approach 2:

    <string name="search_hint"><font size="12">My hint string</font></string>   
 
    val searchSrcTextId = resources.getIdentifier("android:id/search_src_text", null, 
    null)
    val searchEditText = binding.mSearchView.findViewById<View>(searchSrcTextId) as 
    EditText
    searchEditText.hint = getString(R.string.search_hint)

This gives Null Pointer exception on line 3.

Approach 3:

<string name="search_hint"><font size="12">My hint string</font></string>

binding.mSearchView.queryHint = getString(R.string.search_hint)
Or
binding.mSearchView.queryHint = getText(R.string.search_hint)

Approach 4:

binding.mSearchView.queryHint = Html.fromHtml("<small><small> 
<small>"+getString(R.string.hint)
+ "</small></small></small>")

I want to change queryHint text size to 12sp of my androidx.appcompat.widget.SearchView.

Please help, i have tried everything i could, but not able to do it. Thanks in advance! :)

Hint will take the same text size as text . So you have few options here Use Spannable as Hint with RelativeSizeSpan or you can handle the text Size inside text Change listener.

Refer this link How to set SearchView TextSize?

You could do these using code

SearchView searchView = new SearchView(context);
LinearLayout linearLayout1 = (LinearLayout) searchView.getChildAt(0);
LinearLayout linearLayout2 = (LinearLayout) linearLayout1.getChildAt(2);
LinearLayout linearLayout3 = (LinearLayout) linearLayout2.getChildAt(1);
AutoCompleteTextView autoComplete = (AutoCompleteTextView) linearLayout3.getChildAt(0);
autoComplete.setTextSize(60);

Here is another solution

SearchView searchView = new SearchView(context);
AutoCompleteTextView search_text = (AutoCompleteTextView) searchView.findViewById(searchView.getContext().getResources().getIdentifier("android:id/search_src_text", null, null));
search_text.setTextColor(Color.WHITE);
search_text.setTextSize(TypedValue.COMPLEX_UNIT_PX, search_text.setTextSize(TypedValue.COMPLEX_UNIT_PX, getResources().getDimensionPixelSize(R.dimen.text_small));
