簡單 繼承BaseAdapter：

Myadapter代碼：

public class Myadapter extends BaseAdapter {
    private Context context;
    private String[] ss;
   /* private List<User>list;*/
    public Myadapter(Context context,String[] ss){
        super();
        this.context=context;
        this.ss=ss;
    }
    @Override
    
 
//得到個數
    public int getCount() {
        return ss.length;
    }

    @Override
    //得到所以索引，即i值
    public Object getItem(int position) {
        return null;
    }

    @Override
    public long getItemId(int position) {
        return 0;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
       String str
 
=ss[position];
        TextView textView=new TextView(context);
        textView.setText(str);
       return textView;
    }
}

MianActivity：

public class MainActivity extends AppCompatActivity {
   private String[] ss=new String[]{
            "山西","太原","山東","貴陽","天津","北京","洪湖"
    };
    @Override
    
 
protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        ListView listView = (ListView) findViewById(R.id.list_view);
        Myadapter adapter=new Myadapter(this,ss);
       // ArrayAdapter<String> adapter=new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,ss);
        listView.setAdapter(adapter);
    }


}

進階baseAdatapter：

android適配器+listview
