import android.view.Menu;
import android.view.View;
import android.widget.Switch;
import android.widget.Toast;
import android.widget.ToggleButton;
public class MainActivity extends Activity {
 @Override
 protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);
 }
 public void onToggleClicked(View view) {
 /*
  * 强转为Switch类型的
  */
 boolean isChecked = ((Switch) view).isChecked();
 if (isChecked == true) {
  Toast.makeText(MainActivity.this, "打开", 1).show();
 } else {
  Toast.makeText(MainActivity.this, "关闭", 1).show();
 }
 }
 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
 // Inflate the menu; this adds items to the action bar if it is present.
 getMenuInflater().inflate(R.menu.main, menu);
 return true;
 }
