java-如何在Android中使用带有’onCheckedChanged’方法的switch语句？

概述我一直在努力使它起作用,我想要这样,以便可以将两个checkChanged放在一个OnCheckedChanged方法中.到目前为止,我没有任何帮助,但是像以前一样,只有一种情况,而没有switch语句.请您看看我的代码,看看如何修复它才能使它工作？这是代码：publicclassMainActivityextendsActivityi

我一直在努力使它起作用,我想要这样,以便可以将两个checkChanged放在一个OnCheckedChanged方法中.到目前为止,我没有任何帮助,但是像以前一样,只有一种情况,而没有switch语句.请您看看我的代码,看看如何修复它才能使它工作？

这是代码：

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;        }    }

解决方法:

如在日志中：

NoSuchMethodException: onSwitchToggle [class androID.vIEw.VIEw]

表示您已在Switch VIEw xml中添加了androID：onClick =“ onSwitchToggle”属性,但是您忘记在Activity代码中定义方法.

因为您要将setonCheckedchangelistener()添加到Activity中的Switch VIEw,所以不需要在XML中为Switch VIEw设置onClick().只需从XML中删除androID：onClick =“ onSwitchToggle”属性即可.
