效果：

xml：

 <ListView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/listviewId">
    </ListView>

activity：

public class ListviewActivity extends AppCompatActivity {

        //数据源
    private  static final String[] commonFunList = new String[]{
            "ListView1",
            "ListView2",
            "ListView3",
            "ListView4",
            "ListView5"
    };

    private ListView listView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_listview);

        listView = (ListView)findViewById(R.id.listviewId);
        //setAdapter：布局
        listView.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, commonFunList));

        //setOnItemClickListener：监听点击了哪一条list
        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {

                Dialog alertDiaLog = new AlertDialog.Builder(ListviewActivity.this).
                        setMessage("您点击了第" + i + "个item").create();
                alertDiaLog.show();

            }
        });
    }
