我找不到好的解决方案，所以我会建立自己的库来处理这个问题：TokenAutoComplete。这是一个基本示例：
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.getName());
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);
}
}
}
contact_token 的布局代码（您需要找到自己的 x drawable）
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:background="@drawable/token_background">
<TextView android:id="@+id/name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="@android:color/white"
android:textSize="14sp"
android:text="Test Me"
android:padding="2dp" />
<ImageView
android:layout_height="10dp"
android:layout_width="10dp"
android:src="@drawable/x"
android:layout_gravity="center_vertical"
android:layout_marginLeft="3dp"
android:layout_marginRight="5dp" />
</LinearLayout>
令牌背景可绘制
<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>
人物对象代码
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; }
}
示例活动
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", "marshall@example.com"),
new Person("Margaret Smith", "margaret@example.com"),
new Person("Max Jordan", "max@example.com"),
new Person("Meg Peterson", "meg@example.com"),
new Person("Amanda Johnson", "amanda@example.com"),
new Person("Terry Anderson", "terry@example.com")
};
adapter = new ArrayAdapter<Person>(this, android.R.layout.simple_list_item_1, people);
completionView = (ContactsCompletionView)findViewById(R.id.searchView);
completionView.setAdapter(adapter);
completionView.setTokenClickStyle(TokenCompleteTextView.TokenClickStyle.Delete);
}
}
布局代码
<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>
