Usage

Check Box

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

Check Box Grid (2 Cols, Label After)

<com.llollox.androidprojects.compoundbuttongroup.CompoundButtonGroup
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  app:entries="@array/planets"
  app:compoundType="check_box"
  app:numCols="2"
  app:labelOrder="after"/>

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
  
}
 
}
);

Attributes

It is possible to customize the compound button group applying the following options:

Option Name Format Description
w app:compoundType check_box or radio
app:entries array String array of the entries of the compound button group.
app:labelOrder before or after This determines if the label is before or after the compound button. By default is before.
app:numCols int Setting this parameter the compound buttons are shown as a grid and it indicates the number of cols of the grid.

Resources

An android color picker with changeable color drawable for easy styling.

This custom listview basically shows a holder view when it's adapter is empty. For example, you may fetch list datas from network and refresh your adapter with coming data. If the data is empty, your listview shows a huge blank space. With this custom listview, you can show a holder view instead of blank space and your design looks prettier.

Android M was added to check permissions, but permissions checking is so dirty.

This project allows to check permissions easily.

The library distributes canvas animation over set of devices.

A huge set of utils for Android development.
