1.Activity
//横向开关 public class SwitchActivity extends Activity { private Switch switchComponent; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.switch_layout); switchComponent = (Switch)findViewById(R.id.switchId); switchComponent.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { if(isChecked){ Toast.makeText(SwitchActivity.this, "无线网络打开了!", Toast.LENGTH_SHORT).show(); }else{ Toast.makeText(SwitchActivity.this, "无线网络关闭了!", Toast.LENGTH_SHORT).show(); } } }); } }
