How to check if android checkbox is checked within its onClick method (declared in XML)?

try this one :

public void itemClicked(View v) {  //code to check if this checkbox is checked!  CheckBox checkBox = (CheckBox)v;  if(checkBox.isChecked()){  }}

This will do the trick:

  public void itemClicked(View v) {    if (((CheckBox) v).isChecked()) {        Toast.makeText(MyAndroidAppActivity.this,           "Checked", Toast.LENGTH_LONG).show();    }  }

<CheckBox      android:id="@+id/checkBox1"      android:layout_width="wrap_content"      android:layout_height="wrap_content"      android:text="Fees Paid Rs100:"      android:textColor="#276ca4"      android:checked="false"      android:onClick="checkbox_clicked" />

Main Activity from here

   public class RegistA extends Activity {CheckBox fee_checkbox; @Override    protected void onCreate(Bundle savedInstanceState) {      super.onCreate(savedInstanceState);      setContentView(R.layout.activity_regist); fee_checkbox = (CheckBox)findViewById(R.id.checkBox1);// Fee Payment Check box}

checkbox clicked

     public void checkbox_clicked(View v)     {         if(fee_checkbox.isChecked())         {            // true,do the task          }         else         {         }     }
