Question

我有一个活动，其中有一个玩家列表。该列表包含所有玩家的名字。我想为每个名字提供一个微调器，其中包括＆＃34;删除＆＃34;，＆＃34;评价为最佳＆＃34;等等我创建了列表，但无法添加带有一组选项的微调器。

我的代码是。

public class AddPlayerActivity extends AppCompatActivity {

    @InjectView(R.id.players_listView)
    ListView playersListView;

    // Adapter for playersListView
    private ArrayAdapter<String> playersArrayAdapter;

    // Array of the players to be loaded in the list view
    String[] players = {"ABC", "XYZ", "MNO", "GHI"};


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_add_player);
        ButterKnife.inject(this);

        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);


        // Initializing array adapter
        playersArrayAdapter = new ArrayAdapter<>(this, R.layout.players_name, players);
        playersListView.setAdapter(playersArrayAdapter);


        playersListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

            }
        });
    }
}

activity_add_player.xml是 -

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    tools:showIn="@layout/activity_add_player">

        <ListView
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_weight="4"
            android:id="@+id/players_listView"
            android:choiceMode="singleChoice"/>
</LinearLayout>

当您单击listview时，打开Dialog并将自定义布局附加到Dialog而不是微调器。

例如：

在listview clicklistner中写下面的代码 -

 final Dialog alertDialog = new Dialog(Add_Vendor.this);
                        alertDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
                        alertDialog.setContentView(R.layout.layout_taglist);
                        alertDialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

                        alertDialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);

                        alertDialog.show();

                        list = (ListView) alertDialog.findViewById(R.id.list_view);
                        Button btndone  = (Button) alertDialog.findViewById(R.id.button1);

                        CustomAdapterTag cadapter = new CustomAdapterTag(Add_Vendor.this,android.R.layout.simple_spinner_item,     

                                 tagslist);        

                        list.setAdapter(cadapter);

以这种方式，你可以使用customAdaper与“删除”，“评价最佳”等选项

如何针对列表视图的每个项添加微调器
