/**
 * <p>
 * A checkbox is a specific type of two-states button that can be either
 * checked or unchecked. A example usage of a checkbox inside your activity
 * would be the following:
 * </p>
 *
 * <pre class="prettyprint">
 * public class MyActivity extends Activity {
 *     protected void onCreate(Bundle icicle) {
 *         super.onCreate(icicle);
 *
 *         setContentView(R.layout.content_layout_id);
 *
 *         final CheckBox checkBox = (CheckBox) findViewById(R.id.checkbox_id);
 *         if (checkBox.isChecked()) {
 *             checkBox.setChecked(false);
 *         }
 *     }
 * }
 * </pre>
 *  
 * <p>XML attributes

* <p> * See {@link android.R.styleable#CompoundButton CompoundButton Attributes}, * {@link android.R.styleable#Button Button Attributes}, * {@link android.R.styleable#TextView TextView Attributes}, * {@link android.R.styleable#View View Attributes} * </p> */ public class CheckBox extends CompoundButton { public CheckBox(Context context) { this(context, null); } public CheckBox(Context context, AttributeSet attrs) { this(context, attrs, com.android.internal.R.attr.checkboxStyle); } public CheckBox(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } }
