1：和ListView的資料跟新是基本一樣的。

2：Activity程式碼範例

public class MainActivity extends AppCompatActivity {    AlertDialog alertDialog;    View view;    List<String> data = new ArrayList<>();    ListView listView;    ArrayAdapter<String> adapter;    Handler handler=new Handler(){        @Override        public void handleMessage(Message msg) {            super.handleMessage(msg);            adapter.notifyDataSetChanged();        }    };    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        for (int i = 0; i < 100; i++) {            data.add("資料:" + i);        }        view = getLayoutInflater().inflate(R.layout.controller_volume, null);        alertDialog = new AlertDialog.Builder(this).setTitle("Dialog ListView更新").setIcon(R.mipmap.ic_launcher)                .setView(view)                .setPositiveButton("return", new DialogInterface.OnClickListener() {                    public void onClick(DialogInterface paramAnonymousDialogInterface, int paramAnonymousInt) {                    }                }).create();        listView=view.findViewById(R.id.listView);        adapter=new ArrayAdapter<String>(MainActivity.this,android.R.layout.simple_list_item_1,data);        listView.setAdapter(adapter);        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {            @Override            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {                data.remove(data.get(position));                handler.sendEmptyMessageDelayed(100,1000);            }        });        alertDialog.show();    }   }

3：controller_volume.xml 只有一個listView

<?xml version="1.0" encoding="utf-8"?><android.support.constraint.ConstraintLayout    xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent"    android:layout_height="match_parent">    <ListView        android:layout_width="match_parent"        android:layout_height="200dp"        android:id="@+id/listView"/></android.support.constraint.ConstraintLayout>
