我想实现类似于谷歌的Play商店的弹出式菜单，如下图所示。

i would like to implement a popup menu similar to google's play store as shown below.

所以基本上从我个人理解，我需要一个活动，这个活动在它定义的列表视图的布局。我需要创建我的自定义适配器。另外，我需要创建一个列表布局将包含的信息和观点（与3点），将作为按钮启动弹出菜单？那我看到这里的问题是，如何创建一个侦听这种观点只是我如何引用值列表中的观点，即特定的列表项。

so basically from what i understand, i'll need an activity and a layout for this activity with a listview defined in it. i need to create my custom adapter. also, i need to create a list layout would contain the information and a view (with the 3 dots) that will serve as the button to launch the popup menu? the issue that i'm seeing here is that how do i create a listener for this view only and how do i reference the value for that specific list item in the list view.

我没有任何code产品尚未推出，因为我还没有开始任何与此有关。我目前得到理论上的信息，现在，但如果需要，我将创建一个样本code。

i don't have any code available yet as i haven't started anything related to this. i'm currently getting info in theory for now but if required i will create a sample code.

感谢。

HIII ......你可以用这样的..

Hiii... You can use like this..

public class MainActivity extends Activity {
    ListView listView_Actions;
    ArrayList<String> actionsArrayList;
    Button btn_ViewPopUp;
    ArrayAdapter<String> actionsAdapter;
    static final int CUSTOM_DIALOG_ID1 = 1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        btn_ViewPopUp=(Button) findViewById(R.id.btn_ViewPopUp);

        actionsArrayList=new ArrayList<String>();
        actionsArrayList.add("Action 1");
        actionsArrayList.add("Action 2");
    }

    @Override
    protected void onStart() {
        super.onStart();

        btn_ViewPopUp.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                showDialog(CUSTOM_DIALOG_ID1);
                actionsAdapter=new MyCustomBaseAdapteradpt(getApplicationContext(),R.layout.list_actions,actionsArrayList);
                listView_Actions.setAdapter(actionsAdapter);
            }
        });
    }

    @Override
    protected Dialog onCreateDialog(int id) {
        Dialog dialog = null;
        switch (id) {
            case CUSTOM_DIALOG_ID1:
                dialog = new Dialog(MainActivity.this);
                dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
                dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
                dialog.setContentView(R.layout.list_actions);
                listView_Actions = (ListView) dialog.findViewById(R.id.listView_Actions);
                break;
        }
        return dialog;
    }

    class MyCustomBaseAdapterAdapter extends ArrayAdapter<String> 
    {
        public MyCustomBaseAdapterAdapter(Context context, int textViewResourceId, ArrayList<String> actionsArrayList) {
            super(context, textViewResourceId,actionsArrayList);
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            View v = inflater.inflate(R.layout.action_list_cell, null);
            final TextView lblContactAction;
            lblContactAction = (TextView) v.findViewById(R.id.txtContactAction);

            lblContactAction.append(actionsArrayList.get(position));
            return v;
        }
    }
}

现在的XML文件......

Now XML files......

action_list_cell.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:background="@android:color/background_light" >

    <TextView
        android:id="@+id/txtContactAction"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text=""
         android:textSize="18dp"
        android:textColor="@android:color/black" />

</LinearLayout>

list_actions.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" 
    android:background="@drawable/rounded_corner_top">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_margin="10dp"
        android:orientation="vertical" >

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="#DB6A16"
            android:orientation="vertical"
            android:paddingBottom="2dp"
            android:paddingLeft="2dp"
            android:paddingRight="2dp" >

            <ListView
                android:id="@+id/listView_Actions"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:background="#ffffff" >
            </ListView>
        </LinearLayout>
    </LinearLayout>

</LinearLayout>
