Change The Textview Style In Androidstudio

I have created a listview called popuplistfragment.java and list_view.xml.I have added textview in xml file but I dont know where to add code to change the textview in the listview

Solution 1:

Firstly you need to extend Adapter class

publicclassListAdapterextendsArrayAdapter<String> {
   String [] mQuotes;
   publicListAdapter(String [] quotes){
      mQuotes = quotes;
   }
   public View getView(int position, View convertView, ViewGroup parent) {
       Viewv= convertView;
       if (v == null) {
           LayoutInflaterlayoutInflater= LayoutInflater.from(getContext());
           v = layoutInflater.inflate(R.layout.itemlistrow, null);
       }
       TextViewquoteTextView= v.findViewById(R.id.quote_textView);
       quoteTextView.setText(mQuotes[position])
       return v;
   }

   @OverridepublicintgetCount() {
         return quotes.length;
      }
}

Then implement other methods. The next step is to change next code

@OverridepublicvoidonActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    String [] QuoteArray = getResources().getStringArray(R.array.quotes);
    ListAdapter adapter = newListAdapter(QuoteArray);

    setListAdapter(adapter);
    getListView().setOnItemClickListener(this);
}

Then add itemlistrow.xml to Layout folder and change it so:

<?xml version="1.0" encoding="utf-8"?><LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"android:orientation="horizontal"android:layout_width="match_parent"android:layout_height="match_parent"><TextViewandroid:id="@+id/quote_textView"android:layout_width="wrap_content"android:layout_height="wrap_content"/></LinearLayout>

You can customize itemlistrow.xml as you want
