我一直在試圖爲年齡來得到這個工作，我想它，這樣我可以在一個OnCheckedChanged方法把兩者的CheckedChanged。到目前爲止，我的工作並不成功，但正如我以前所做的那樣，只有一個案例，沒有切換語句的工作。請你可以看看我的代碼，看看我可以修復它，使其工作？如何在android中使用'onCheckedChanged'方法的switch語句？
下面是代碼：
public class MainActivity extends Activity implements OnClickListener, OnCheckedChangeListener {
Button sensorButton;
Button newScreen;
Switch vibrateToggle;
Switch lightsToggle;
NotificationManager nm1;
NotificationManager nm2;
static final int uniqueID1 = 12345;
static final int uniqueID2 = 54321;
OnCheckedChangeListener vibrateListener;
OnCheckedChangeListener lightsListener;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
sensorButton = (Button)this.findViewById(R.id.sensorButton);
sensorButton.setOnClickListener(this);
newScreen = (Button)this.findViewById(R.id.newScreen);
newScreen.setOnClickListener(this);
nm1 = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
nm1.cancel(uniqueID1);
nm2 = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
nm2.cancel(uniqueID2);
vibrateToggle = (Switch)this.findViewById(R.id.switch1);
vibrateToggle.setOnCheckedChangeListener(vibrateListener);
lightsToggle = (Switch)this.findViewById(R.id.lightSwitch);
lightsToggle.setOnCheckedChangeListener(lightsListener);
}
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
// TODO Auto-generated method stub
switch(buttonView.getId()){
case R.id.switch1:
Toast.makeText(this, "Vibrate Notification is " + (isChecked ? "ON" : "OFF"),
Toast.LENGTH_SHORT).show();
if (isChecked) {
// The toggle is enabled
Intent vibrateIntent = new Intent(this, MainActivity.class);
PendingIntent vibratePi = PendingIntent.getActivity(this, 0, vibrateIntent, 0);
NotificationCompat.Builder vibrateN = new NotificationCompat.Builder(this);
vibrateN.setContentIntent(vibratePi);
vibrateN.setDefaults(Notification.DEFAULT_VIBRATE);
Notification vn = vibrateN.build();
nm2.notify(uniqueID2, vn);
} else {
// The toggle is disabled
}
case R.id.lightSwitch:
Toast.makeText(this, "Lights Notification is " + (isChecked ? "ON" : "OFF"),
Toast.LENGTH_SHORT).show();
if (isChecked) {
// The toggle is enabled
Intent lightsIntent = new Intent(this, MainActivity.class);
PendingIntent lightsPi = PendingIntent.getActivity(this, 0, lightsIntent, 0);
NotificationCompat.Builder lightsN = new NotificationCompat.Builder(this);
lightsN.setContentIntent(lightsPi);
lightsN.setDefaults(Notification.DEFAULT_LIGHTS);
Notification ln = lightsN.build();
nm2.notify(uniqueID2, ln);
} else {
// The toggle is disabled
}
break;
}
}
這是我得到的logcat：

android:onClick="onSwitchToggle"屬性：你不_must_，（否則這將是無用的），但你真的應該，在大多數情況下， – njzk2 2013-03-14 16:25:45解決或仍然沒有問題？ – 2013-03-14 16:42:25
