    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:entries="@array/planets"
    app:compoundType="check_box"

Radio

<com.llollox.androidprojects.compoundbuttongroup.CompoundButtonGroup
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:entries="@array/planets"
    app:compoundType="radio"
    app:labelOrder="after"/>

Radio Grid (3 Cols)

<com.llollox.androidprojects.compoundbuttongroup.CompoundButtonGroup
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:entries="@array/planets"
    app:compoundType="radio"
    app:numCols="3"
    app:labelOrder="after"/>

Getters

• List<Integer> getCheckedPositions() Returns the current checked positions

List<Integer> positions = compoundButtonGroup.getCheckedPositions();

• CompoundType getCompoundType() Get the type of the compound buttons.

compoundButtonGroup.getCompoundType();

• LabelOrder getLabelOrder() Get the label order of the compound buttons. This determines if the label is before or after the compound button.

compoundButtonGroup.getLabelOrder();

• int getNumCols() Get the current number of cols.

compoundButtonGroup.getNumCols();

Setters

• void setCheckedPosition(int position) Checks the button at the position passed as argument. Typically to be used with radio buttons.

int position = 3;
compoundButtonGroup.setCheckedPosition(position);

• void setCheckedPositions(List<Integer> positions) Checks all the buttons at the positions passed as argument. Typically to be used with check box buttons.

List<Integer> positions = new ArrayList<Integer>(){{add(2); add(4);}};
compoundButtonGroup.setCheckedPositions(positions);

• void setCompoundType(CompoundType compoundType) Set the type of the compound buttons. Allowed values are: CompoundType.CHECK_BOX, CompoundType.RADIO. In order to see the changes on UI please call the reDraw() method.

compoundButtonGroup.setCompoundType(CompoundButtonGroup.CompoundType.RADIO);

• void setEntries(List<String> entries) Set the entries for the compound button group. In order to see the changes on UI please call the reDraw() method.

List<String> entries = new ArrayList<String>(){{add("Mars"); add("Mercury"); add("Earth");}};
compoundButtonGroup.setEntries(entries);

• void setEntries(HashMap<String, String> entries) Set the entries for the compound button group. The key / value pair represent the value / label of the entry respectively. In order to see the changes on UI please call the reDraw() method.

LinkedHashMap<String, String> map = new LinkedHashMap<>();
map.put("house", getString(R.string.house));
map.put("orange", getString(R.string.orange));
compoundButtonGroup.setEntries(map);
compoundButtonGroup.reDraw();

• void setLabelOrder(LabelOrder LabelOrder) Set the label order of each compound button. This determines if the label is before or after the compound button. Allowed values are: LabelOrder.BEFORE, LabelOrder.AFTER. In order to see the changes on UI please call the reDraw() method.

compoundButtonGroup.setLabelOrder(CompoundButtonGroup.LabelOrder.AFTER);

• void setNumCols(int numCols) Set the number of cols. If it is greater than 1 the compound buttons are shown as a grid. NB. It cannot be smaller than 1! In order to see the changes on UI please call the reDraw() method.

int numCols = 2;
compoundButtonGroup.setNumCols(numCols);

Listeners

OnButtonSelectedListener

compoundButtonGroup.setOnButtonSelectedListener(new CompoundButtonGroup.OnButtonSelectedListener() {
    @Override
    public void onButtonSelected(int position, String value, boolean isChecked) {
        // Your code
    }
});
