Android Custom CheckBox
Android gives office to tweak the UI of view components
instead of default.
You can make custom CheckBox in android. Thus, you can
include some unique pictures of checkbox on the design.
Example Of Custom CheckBox
In this precedent, we make both default just as custom
checkbox. Include the accompanying code in activity_main.xml document.
activity_main.xml
File :- activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="example.javatpoint.com.customcheckbox.MainActivity">
<TextView
android:id="@+id/textView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:textSize="25dp"
android:text="Default Check Box"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
<CheckBox
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New CheckBox"
android:id="@+id/checkBox"
android:layout_below="@+id/textView1"
android:layout_centerHorizontal="true"
android:layout_marginTop="46dp" />
<CheckBox
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New CheckBox"
android:id="@+id/checkBox2"
android:layout_below="@+id/checkBox"
android:layout_alignLeft="@+id/checkBox"
android:layout_alignStart="@+id/checkBox" />
<View
android:layout_width="fill_parent"
android:layout_height="1dp"
android:layout_marginTop="200dp"
android:background="#B8B894"
android:id="@+id/viewStub" />
<CheckBox
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="CheckBox 1"
android:id="@+id/checkBox3"
android:button="@drawable/customcheckbox"
android:layout_below="@+id/viewStub"
android:layout_centerHorizontal="true"
android:layout_marginTop="58dp" />
<CheckBox
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="CheckBox 2"
android:id="@+id/checkBox4"
android:button="@drawable/customcheckbox"
android:layout_below="@+id/checkBox3"
android:layout_alignLeft="@+id/checkBox3"
android:layout_alignStart="@+id/checkBox3" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceSmall"
android:textSize="25dp"
android:text="Custom Check Box"
android:id="@+id/textView"
android:layout_alignTop="@+id/viewStub"
android:layout_centerHorizontal="true" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Show Checked"
android:id="@+id/button"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true" />
</RelativeLayout>

Presently actualize a selector in another document
(checkbox.xml) under drawable organizer which alters the checkbox.
Checkbox.xml
File : checkbox.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true" android:drawable="@drawable/checked" />
<item android:state_checked="false" android:drawable="@drawable/unchecked"/>
</selector>

Activity Class
File: MainActivity.java
package example.cptech.com.customcheckbox;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
CheckBox cb1,cb2;
Button button;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
cb1=(CheckBox)findViewById(R.id.checkBox3);
cb2=(CheckBox)findViewById(R.id.checkBox4);
button=(Button)findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
StringBuilder sb=new StringBuilder("");
if(cb1.isChecked()){
String s1=cb1.getText().toString();
sb.append(s1);
}
if(cb2.isChecked()){
String s2=cb2.getText().toString();
sb.append("\n"+s2);
}
if(sb!=null && !sb.toString().equals("")){
Toast.makeText(getApplicationContext(), sb, Toast.LENGTH_LONG).show();
}
else{
Toast.makeText(getApplicationContext(),"Nothing Selected", Toast.LENGTH_LONG).show();
}
}
});
}
}
