简单的：

ArrayAdapter<String> arrayAdapter=new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,data);

listView.setAdapter(arrayAdapter);

自定义的：

public class MyArrayAdapter extends ArrayAdapter<MyList> {    private int resourceId;    public MyArrayAdapter(Context context,int textViewResourceId,List<MyList> object)    {        super(context,textViewResourceId,object);        resourceId=textViewResourceId;    }    @Override    public View getView(int position, View convertView, ViewGroup parent) {        MyList myList=getItem(position);        View view= LayoutInflater.from(getContext()).inflate(resourceId,null);        ImageView imageView=(ImageView) view.findViewById(R.id.layoutImageView);        TextView textView=(TextView) view.findViewById(R.id.layoutTextView);        imageView.setImageResource(myList.imageId);        textView.setText(myList.name);        return  view;    }}

public class MyList {    String name;   int imageId;    public MyList(String name,int imageId)    {        this.name=name;        this.imageId=imageId;    }

public class MainActivity extends AppCompatActivity {    ListView listView;    List<MyList> myLists=new ArrayList<MyList>();    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        listView=(ListView) findViewById(R.id.mainListView);        init();    }    private void init()    {        MyList myList=new MyList("a",R.drawable.userlogo);        myLists.add(myList);        myList=new MyList("b",R.drawable.userlogo);        myLists.add(myList);    }    public void putDown(View v) {        MyArrayAdapter adapter=new MyArrayAdapter(this,R.layout.layout,myLists);        listView.setAdapter(adapter);    }}

<ImageView    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:id="@+id/layoutImageView"/><TextView    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:id="@+id/layoutTextView"/>
