import android.widget.Toast;public class SwitchActivity extends AppCompatActivity {Switch mSwitch1;Switch mSwitch2;@Override
    protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_switch);mSwitch1 = (Switch)findViewById(R.id.switch_1);mSwitch2 = (Switch)findViewById(R.id.switch_2);CompoundButton.OnCheckedChangeListener checkedChangeListener = new CompoundButton.OnCheckedChangeListener() {@Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {switch (buttonView.getId() ){case R.id.switch_1:if ( isChecked ){Toast.makeText(SwitchActivity.this, "Wifi on", Toast.LENGTH_SHORT).show();}else{Toast.makeText(SwitchActivity.this, "Wifi off", Toast.LENGTH_SHORT).show();}break;case R.id.switch_2:if(isChecked){Toast.makeText(SwitchActivity.this, "on", Toast.LENGTH_SHORT).show();}else{Toast.makeText(SwitchActivity.this, "off", Toast.LENGTH_SHORT).show();}break;default:break;}}};mSwitch1.setOnCheckedChangeListener(checkedChangeListener);mSwitch2.setOnCheckedChangeListener(checkedChangeListener);}
}

layout布局文件

    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="shortcut.song.com.myapplication.SwitchActivity"><LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
