RecyclerView with editTags

Question

我在做一個應用程序。因爲我需要搜索回收商物品，並且一旦用戶從回收商選擇物品，那麼它應該被設置爲該編輯文本的標籤。我從https://android-arsenal.com/details/1/3581這樣做過，但它不能正常工作。任何幫助我可以如何實現從回收站視圖中搜索項目並將其設置爲該選定項目的編輯標籤。

這是供參考的屏幕。

我做喜歡提前這個

public class ActivityTagFriends extends BaseActivity implements TagsEditText.TagsEditListener, View.OnClickListener { 
    TextView tv_cancel, tv_title, tv_Done; 
    RecyclerView rv_TagFriends; 
    private TagsEditText mTagsEditText; 

    private List<String> list = new ArrayList<String>(); 
    TagFriendsAdapter mAdapter; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) {

     tv_cancel = (TextView) findViewById(R.id.tvCancel); 
     tv_cancel.setText("Cancel"); 
     tv_cancel.setTextColor(getResources().getColor(R.color.red)); 
     tv_title = (TextView) findViewById(R.id.tvTitle); 
     tv_title.setText("Tag Friends"); 
     tv_title.setTextColor(getResources().getColor(R.color.black)); 
     tv_Done = (TextView) findViewById(R.id.tvDone); 
     tv_Done.setText("Done"); 
     tv_Done.setTextColor(getResources().getColor(R.color.red)); 

     rv_TagFriends= (RecyclerView) findViewById(R.id.rv_TagFriends);

好我得到了你的問題，使用此代碼

你的活動佈局（activity_main.xml中）

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:TagsEditText="http://schemas.android.com/apk/res-auto" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical" 
    tools:context="mabbas007.myapplication.MainActivity"> 

    <mabbas007.tagsedittext.TagsEditText 
    android:id="@+id/tagsEditText" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    TagsEditText:allowSpaceInTag="true" 
    TagsEditText:tagsBackground="@drawable/square_default" 
    TagsEditText:tagsCloseImageRight="@drawable/tag_close" /> 

    <TextView 
    android:background="@android:color/darker_gray" 
    android:padding="10dp" 
    android:gravity="center" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:text="Suggestion"/> 

    <android.support.v7.widget.RecyclerView 
    android:id="@+id/rv" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"/> 
    </LinearLayout> 

適配器佈局（adapter_item.xml）

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

    <TextView 
    android:padding="10dp" 
    android:id="@+id/text" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" /> 
    <View 
    android:layout_width="match_parent" 
    android:background="@color/colorAccent" 
    android:layout_height="1dp"/> 

    </LinearLayout>
