I wanted to make my markup for ListView , namely add buttons to the list items. I did this: in the layout I created a listview.xml file with the contents:

 <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:orientation="horizontal" android:layout_width="match_parent" android:layout_height="match_parent" android:id="@+id/listView"> <TextView android:layout_width="wrap_content" android:layout_weight="1" android:layout_height="41dp" android:id="@+id/text1" /> <ImageButton android:layout_width="wrap_content" android:layout_height="wrap_content" app:srcCompat="@drawable/icon_share" android:id="@+id/imageButton3" android:background="@drawable/circle_button_white" android:layout_marginRight="5dp" /> <ImageButton android:layout_width="wrap_content" android:layout_height="wrap_content" app:srcCompat="@drawable/icon_search" android:id="@+id/imageButton2" android:background="@drawable/circle_button_white" /> </LinearLayout>

Further in the code I wrote the following:

 arrayAdapter = new ArrayAdapter<String>(MainActivity.this, R.layout.listview, rusArr);

An error:

    When creating an ArrayAdapter , the markup file specified by the second constructor argument must consist of only one TextView .

    If you have your own markup file for the ListView element, then you need to create your own adapter. You can read more about this, for example, here .

    In general, I would recommend using RecyclerView instead of ListView , because it is more flexible (it was he who replaced ListView ).

    • And for my case how to be? so that the buttons were also - Michael

      RecyclerView , RecyclerView is in the support library android.support.v7.widget.RecyclerView , as its name suggests, it can be used starting from version 7 of the API, that is, from Android 2.1. - post_zeew
