布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <Button
        android:id="@+id/my_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Toggle Wifi" />
</LinearLayout>

主要活动

  @Override
  public void onCreate(Bundle savedInstanceState)
  {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    final Button myButton = (Button) findViewById(R.id.my_button);
    myButton.setOnClickListener(new View.OnClickListener()
    {
      @Override
      public void onClick(View v)
      {
        final WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
        wifi.setWifiEnabled(!wifi.isWifiEnabled());
      }
    });
  }
