AutoLabelUI

Android library to place labels next to another. If there is not enough space for the next label, it will be added in a new line.

Try out the sample application on Google Play.

Demo

Including in Your Project

Last version is 1.0.1

Just add the following statement in your build.gradle

compile 'com.github.davidpizarro:autolabelui:VERSION'

You may also add the library as an Android Library to your project. All the library files live in library.

Usage

To add the AutoLabelUI to your layout, add this to your xml

<com.dpizarro.autolabel.library.AutoLabelUI
        android:id="@+id/label_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

You can add custom attributes in your xml to customize: drawables, colors, counters, background, behaviors...

<com.dpizarro.autolabel.library.AutoLabelUI
        android:id="@+id/label_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        autolabel:max_labels="10"
        autolabel:show_cross="true"
        autolabel:text_color="@android:color/white"
        autolabel:text_size="@dimen/label_title_size"
        autolabel:icon_cross="@drawable/cross"
        autolabel:label_background_res="@color/default_background_label"
        autolabel:label_padding="@dimen/label_padding"
        autolabel:label_clickable="true"/>
        

Review attrs.xml file to know the list of shapes ready to be used in the library.

This configuration can be also provided programmatically. You can use AutoLabelUI programatically, using the Builder class to set the settings and the desired functionalities:

AutoLabelUI mAutoLabel = (AutoLabelUI) view.findViewById(R.id.label_view);

AutoLabelUISettings autoLabelUISettings = new AutoLabelUISettings.Builder()
                                                                 .withMaxLabels(5)
                                                                 .withIconCross(R.drawable.cross)
                                                                 .withBackgroundResource(R.drawable.round_corner_background)
                                                                 .withLabelsClickables(false)
                                                                 .withShowCross(true)
                                                                 .withTextColor(android.R.color.holo_red_dark)
                                                                 .withTextSize(R.dimen.label_title_size)
                                                                 .withLabelPadding(R.dimen.label_padding)
                                                                 .build();

mAutoLabel.setSettings(autoLabelUISettings);

You can set/get values programatically:

mAutoLabel.getBackgroundResource();
mAutoLabel.getTextColor();
mAutoLabel.getTextSize();
mAutoLabel.isLabelsClickables();
mAutoLabel.setTextColor(android.R.color.holo_red_dark);
mAutoLabel.setMaxLabels(5);
mAutoLabel.setBackgroundResource(R.drawable.round_corner_background);
...

You can get Label using:

Label label = mAutoLabel.getLabel(1);
List<Label> labels = mAutoLabel.getLabels();

or remove them all:

mAutoLabel.clear();

To know when you have reached the limit of Labels to add, you will need to implement the onLabelsCompleted interface:

mAutoLabel.setOnLabelsCompletedListener(new AutoLabelUI.OnLabelsCompletedListener() {
    @Override
    public void onLabelsCompleted() {
        Toast.makeText(getActivity(), "Completed!", Toast.LENGTH_SHORT).show();
    }
});

To know when you have deleted all Labels, you will need to implement the onLabelsEmpty interface:

mAutoLabel.setOnLabelsEmptyListener(new AutoLabelUI.OnLabelsEmptyListener() {
    @Override
    public void onLabelsEmpty() {
        Toast.makeText(getActivity(), "EMPTY!", Toast.LENGTH_SHORT).show();
    }
});

To know when you have deleted a Label, you will need to implement the onRemoveLabel interface:

mAutoLabel.setOnRemoveLabelListener(new AutoLabelUI.OnRemoveLabelListener() {
    @Override
    public void onRemoveLabel(View view, int position) {
        adapter.setItemSelected(position, false);
    }
});

To know when you have clicked a Label, you will need to implement the onClickLabel interface:

mAutoLabel.setOnLabelClickListener(new AutoLabelUI.OnLabelClickListener() {
    @Override
    public void onClickLabel(View v) {
        Toast.makeText(getActivity(), ((Label) v).getText() , Toast.LENGTH_SHORT).show();
    }
});

Or browse the source code of the sample application for a complete example of use.

autolabelui's Issues

setTextColor only takes id resource and sometimes color int

Hi,
I can't set the color in code, Im trying to use android palette and the int color I get won't be set as a color, but sometimes works.
I find out that the setTextColor only takes a resource id and if an exception is thrown then the color int is set.

Could you add a another setColor that takes a color int?

How is the animation of the labels implemented?

Add RTL support

Please remove synthetic methods

There’s no true nesting in Java. Hence, any access to private members of outer class from nested class will have to go via a package scoped method generated by Java to facilitate the call.

To reduce method, make methods of outer class package scoped.

Align center tag content

Hi!
Congratulations for the library, it´s amazing. I would like to ask if there is any way to center horizontal tags, instead of floating them left (align left). Or if you have any clue where I may be working around to get it.

Thank you!.

I mean i need autolabel ui inside hoizontal scroll view so the labels doesnt go to next line and scrolls inside horizontal scroll view

and other thing is i should be able to set the orientation

getLabel problem

I added this library to gradle in Android studio. When I try to call getLabel or getLabels methods it shows that there are no such methods and in .class file I don't see them.
What can be the reason?

OnRemoveLabelListener position returnes -1

assigning an id to each label

Hi all,
I just want to assign id to each label. I tried mAutoLabel.setId("some_id"); but ((Label) v).getId() is returning -1 for every label.
How can I achieve it?

OnRemoveLabelListener position returnes -1

mAutoLabel.setOnRemoveLabelListener(new AutoLabelUI.OnRemoveLabelListener() {
    @Override
    public void onRemoveLabel(View view, int position) {
        Log.i("Position","Position: " + position); //<---- This always return -1 when clicking the x on the label.
    }
});

Adding/Removing items animation disturbs the whole layout.

I have a CollapsingToolbarLayout. In container layout , i have an EditText & a Submit Button. After adding/removing one or two items using AutoLableUI on clicking Submit Button, the whole layout moves towards upward and overlaps the collapsing toolbar layout. Same Issue in another layout, where i am using Toolbar Layout along with some tabs.

Label shape

Is it possible to change the shape? Rounded edges etc...?

Problem position when detete a tag

onRemoveLabel(View view, int position). position value allway is -1 when i delete a tag. Something went wrong here?

Is it possible to associate an id for each label ?

I want to set an id for each label in addition to the text.

Issue when adding more tags

When adding tags and lines are exceeded than 2 then issue occurs, tags are cutting from bottom as attached screen-shot

OnRemoveLabelListener's onRemoveLabel wrong signature

Seems OnRemoveLabelListener's onRemoveLabel signature is incorrect. Instead of

onRemoveLabel(View view, int position);

it should be rather

onRemoveLabel(Label removedLabel, int position);

removeLabel(String labelToRemove) is not working

the findViewWithTag(labelToRemove) always return null

Padding to IconCross?

My icon cross is to big. can I add a padding to it somehow?

how to select(change background color) only one label at a time and deselect others(change background color)

Can not add to project by gradle

I tried to add this lib to to my project with compile 'com.github.davidpizarro:autolabelui:VERSION' to my gradle file but I receive the message Error:(39, 13) Failed to resolve: com.github.davidpizarro:autolabelui:VERSION

Please help...

setOnRemoveLabelListener() is being invoked with position = -1

When I attach setOnRemoveLabelListener(), it is always being invoked with position equals to -1, not the index of label. I see it comes form this code:

    if (listenerOnRemoveLabel != null) {
        if (view.getTag() instanceof Integer) {
            listenerOnRemoveLabel.onRemoveLabel(view, (Integer) view.getTag());
        } else {
            listenerOnRemoveLabel.onRemoveLabel(view, -1);
        }
    }

but addLabel(String label) does sets tag on label as label.setTag(textLabel); so it will not work.

In general the whole concept seem fundamentally broken here, as this position should be obtained dynamically, not from tag, as removing any label is not updating stored position of remaining tags' which will cause troubles when one is i.e. trying to keep labels in sync with something else. For now the only solution seem to be to use labels (strings) and then sync base on this, but it's not efficient.

Add list of labels

For example

List<String> tags = new ArrayList<>();
tags.add("cars");
tags.add("home");
tags.add("people");

AutoLabelUI mAutoLabel = (AutoLabelUI) findViewById(R.id.tags);
mAutoLabel.addLabels(tags);
