Java 带芯片的 Android AutoCompleteTextView

Question

提问by nmvictor

I am not sure I am using the right words for this UI feature, but I have attached a snapshot of what I am looking to achieve in my app.

我不确定我对这个 UI 功能使用了正确的词，但我附上了我希望在我的应用程序中实现的目标的快照。

Its used by Go SMS, where a user types contacts in an edit text, after the user selects a contact from the completion drop down, the contact is inserted in the edit text as show in the attached image.The edit text is still open to accept further input.

它被 Go SMS 使用，其中用户在编辑文本中键入联系人，在用户从完成下拉列表中选择联系人后，联系人将插入到编辑文本中，如附加图像所示。编辑文本仍然打开接受进一步的输入。

For my app, I would like to do the grouping and insertion as soon as the user enters a comma, Just like the Tag input for StackOverflow works (But I believe I can handle that alone.) My problem is what kind of View is this or how do I modify an EditText to behave like this?

对于我的应用程序，我想在用户输入逗号后立即进行分组和插入，就像 StackOverflow 的标签输入工作一样（但我相信我可以单独处理。）我的问题是这是什么类型的视图或者如何修改 EditText 使其表现得像这样？

EditText with Grouped Values

带有分组值的 EditText

Thanks.

谢谢。

Two more Chips libraries.

还有两个芯片库。

Android Chips. Unlike some other this one is updated to have visuals reflecting the newly released "Material Design" standard.
Token Auto Complete. It is an Android Gmail style token auto-complete text field and filter.

安卓芯片。与其他一些不同的是，这个更新后的视觉效果反映了新发布的“材料设计”标准。
令牌自动完成。它是一个 Android Gmail 风格的令牌自动完成文本字段和过滤器。

I think we can build our own chips view with Recycler view and Edit text or Auto complete text view. So we can customize it easily.

我认为我们可以使用 Recycler 视图和 Edit text 或 Auto complete text view 构建我们自己的芯片视图。所以我们可以很容易地定制它。

1. Created a tag shape say, tags_layout.xml in Drawable

1.在Drawable中创建了一个标签形状，比如tags_layout.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#cfcfcf">
</solid>
<corners android:radius="20dp">
</corners>

2. Created a layout for recycler view

2. 为回收者视图创建布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="5dp"
android:layout_margin="4dp"
android:gravity="center"
android:background="@drawable/tags_layout">
<TextView
    android:id="@+id/tag_textView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:maxLines="1"
    android:maxLength="25"
    android:ellipsize="end"
    android:padding="2dp"
    android:text="Hello"/>
<ImageView
    android:id="@+id/tag_closeBtn"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/ic_close"/>

3. In our activity layout, we implement widgets recycler view just above edit text to keeping tags and edit text or Autocomplete text view to enter tags.

3. 在我们的活动布局中，我们在编辑文本上方实施小部件回收器视图以保留标签并编辑文本或自动完成文本视图以输入标签。

   <android.support.v4.widget.NestedScrollView
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">
<android.support.v7.widget.RecyclerView
    android:id="@+id/tagsRecyclerView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">
</android.support.v7.widget.RecyclerView>
        <EditText
            android:id="@+id/tagsEditText"
            android:inputType="text"
            android:imeOptions="actionDone"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />
    </LinearLayout>
</android.support.v4.widget.NestedScrollView>

4. Created a model java class for recycler view

4.为回收者视图创建了一个模型java类

        public class RecyclerModel {
    private String tagText;

    public RecyclerModel(String tagText){
        this.tagText = tagText;
    }
    public String getTagText() {
        return tagText;
    }

    public void setTagText(String tagText) {
        this.tagText = tagText;
    }
}

5. Adapter class for recycler view

5. 用于回收者视图的适配器类

    public class RecyclerAdapter extends RecyclerView.Adapter<RecyclerAdapter.RecyclerAdapterHolder> {
    Context context;
    ArrayList<RecyclerModel> model = new ArrayList<>(  );

    public RecyclerAdapter(Context context,ArrayList<RecyclerModel> model){
        this.context = context;
        this.model = model;
    }

    @NonNull
    @Override
    public RecyclerAdapterHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View itemView = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.recycler_layout, parent, false);

        return new RecyclerAdapterHolder(itemView);
    }

    @Override
    public void onBindViewHolder(final RecyclerAdapterHolder holder, final int position) {
        final RecyclerModel mod = model.get( position );
        holder.tagTextView.setText( mod.getTagText() );
        //remove tag on click x button
        holder.tagImageView.setOnClickListener( new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                model.remove( position );
                notifyDataSetChanged();
            }
        } );
    }

    @Override
    public int getItemCount() {
        return model.size();
    }

    public static class RecyclerAdapterHolder extends RecyclerView.ViewHolder {
        public TextView tagTextView;
        public ImageView tagImageView;
        public RecyclerAdapterHolder(View itemView) {
            super( itemView );
            tagTextView = itemView.findViewById( R.id.tag_textView );
            tagImageView = itemView.findViewById( R.id.tag_closeBtn );
        }
    }
}

6. Finally, In our activity, add data to recycler on entering data in edit text

6. 最后，在我们的活动中，在编辑文本中输入数据时将数据添加到回收器

public class MainActivity extends AppCompatActivity {
    RecyclerView tagsRecyclerView;
    EditText tagsEditText;
    ArrayList<RecyclerModel> recyclerModels = new ArrayList<>(  );

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate( savedInstanceState );
        setContentView( R.layout.activity_main );
        tagsRecyclerView = findViewById( R.id.tagsRecyclerView );
        tagsEditText = findViewById( R.id.tagsEditText );
        tagsEditText.setOnEditorActionListener( new TextView.OnEditorActionListener() {
            @Override
            public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
                if (actionId == EditorInfo.IME_ACTION_DONE) {
                    Toast.makeText( MainActivity.this,"hello",Toast.LENGTH_SHORT );
                    String str = tagsEditText.getText().toString();
                    if(str != null && !str.equals( "" )) {
                        getUpdateData( str );
                        tagsEditText.setText( null );
                        RecyclerAdapter adapter = new RecyclerAdapter( MainActivity.this, recyclerModels );
                        FlexboxLayoutManager gridLayout = new FlexboxLayoutManager( MainActivity.this );
                        tagsRecyclerView.setLayoutManager( gridLayout );
                        tagsRecyclerView.setAdapter( adapter );
                    }
                }
                return false;
            }
        } );
    }

    private void getUpdateData(String str) {
        RecyclerModel model = new RecyclerModel( str );
        recyclerModels.add( model );
    }
}

7. Manifest file should contain gradles

7. 清单文件应包含 gradles

implementation 'com.android.support:recyclerview-v7:27.1.1'
implementation 'com.google.android:flexbox:1.0.0'
