令牌EDITTEXT（场）的Andr​​oid [英] Token Edittext (Field) android

问题描述

由于某种原因，我需要像在此图像中红色部分EDITTEXT：

Because some reason I need a Edittext like the red part in this image :

每当用户preSS删除键盘按钮，的EditText将删除一个令牌而不是一个字。 所以，我的问题是：  我们有喜欢它的存在控制？ 如果还是不行，你知道如何定制一个。 注：我不需要用同样的100％。现在，我正在考虑使用TextWatcher或setKeyListener方法删除功能。

Whenever the user press delete button on keyboard, the edittext will delete one token instead of one word. So, my question are : Do we have an exist control like it? or If not, do you know how can customize one. Note : I don't need it the same 100%. Right now, I am thinking about using a TextWatcher or setKeyListener method for delete feature.

感谢你这么多的帮助。很遗憾，因为我的英语不是很好。

Thank you so much for any help. And sorry because my English is not really well.

推荐答案

我已经把 TokenAutoComplete在github 我们在Splitwise使用。我找不到这样的事在Android SDK，所以我做了我自己。

I've put together TokenAutoComplete on github for our use at Splitwise. I couldn't find anything like this in the Android SDK, so I made my own.

在我的控制行为将不匹配您的期望只有一个地方是，当你删除最最近完成的标记，它会变成这个词了。所有其他标记得到彻底删除。

The only place where the behavior of my control will not match your expectations is that when you delete the most-recently completed token, it turns into the word again. All other tokens get completely deleted.

下面是一个基本的例子：

Here's a basic example:

public class ContactsCompletionView extends TokenCompleteTextView {
    public ContactsCompletionView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    protected View getViewForObject(Object object) {
        Person p = (Person)object;

        LayoutInflater l = (LayoutInflater)getContext().getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
        LinearLayout view = (LinearLayout)l.inflate(R.layout.contact_token, (ViewGroup)ContactsCompletionView.this.getParent(), false);
        ((TextView)view.findViewById(R.id.name)).setText(p.getEmail());

        return view;
    }

    @Override
    protected Object defaultObject(String completionText) {
        //Stupid simple example of guessing if we have an email or not
        int index = completionText.indexOf('@');
        if (index == -1) {
            return new Person(completionText, completionText.replace(" ", "") + "@example.com");
        } else {
            return new Person(completionText.substring(0, index), completionText);
        }
    }
}

布局$ C $下contact_token（你可以使用任何种类的布局，或在这里如果你想在令牌图像可以抛出的ImageView中）

Layout code for contact_token (you can use any kind of layout here or could throw an ImageView in if you want images in the token)

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_height="wrap_content"
    android:layout_width="wrap_content">

    <TextView android:id="@+id/name"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/token_background"
        android:padding="5dp"
        android:textColor="@android:color/white"
        android:textSize="18sp" />

</LinearLayout>

令牌backgound绘制

Token backgound drawable

<shape xmlns:android="http://schemas.android.com/apk/res/android" >
    <solid android:color="#ffafafaf" />
    <corners
        android:topLeftRadius="5dp"
        android:bottomLeftRadius="5dp"
        android:topRightRadius="5dp"
        android:bottomRightRadius="5dp" />
</shape>

Person对象code

Person object code

public class Person implements Serializable {
    private String name;
    private String email;

    public Person(String n, String e) { name = n; email = e; }

    public String getName() { return name; }
    public String getEmail() { return email; }

    @Override
    public String toString() { return name; }
}

样活性

public class TokenActivity extends Activity {
    ContactsCompletionView completionView;
    Person[] people;
    ArrayAdapter<Person> adapter;

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

        people = new Person[]{
                new Person("Marshall Weir", "[e-mail]"),
                new Person("Margaret Smith", "[e-mail]"),
                new Person("Max Jordan", "[e-mail]"),
                new Person("Meg Peterson", "[e-mail]"),
                new Person("Amanda Johnson", "[e-mail]"),
                new Person("Terry Anderson", "[e-mail]")
        };

        adapter = new ArrayAdapter<Person>(this, android.R.layout.simple_list_item_1, people);

        completionView = (ContactsCompletionView)findViewById(R.id.searchView);
        completionView.setAdapter(adapter);
    }
}

布局code

Layout code

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <com.tokenautocomplete.ContactsCompletionView
        android:id="@+id/searchView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

</RelativeLayout>
