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 1.0.0

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:background_res="@color/default_background_label"
        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(android.R.color.holo_blue_bright)
                                                                 .withLabelsClickables(false)
                                                                 .withShowCross(true)
                                                                 .withTextColor(android.R.color.holo_red_dark)
                                                                 .withTextSize(R.dimen.label_title_size)
                                                                 .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);
...

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.
