请教：挂断电话可以通过代码实现吗？
代码判断是否那个系统拨号的界面显示（也就是正在拨号），是的话，用代码挂断它，就相当于按了那个红色的取消键。查了半天资料也没有搞定，有朋友解决过这个问题吗？
[解决办法]
android没有提供直接的挂断电话的API，要用代码直接挂断电话，必须先导入两个aidl包：
android.telephony和com.android.internal.telephony,然后可按如下代码，进行挂断电话：
TelephonyManager telephone = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
PhoneStateListener listener = new PhoneStateListener() {
@Override
public void onCallStateChanged(int state, String number) {
if("关闭".equals(check)){
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
break;
case TelephonyManager.CALL_STATE_RINGING:
break;
}
}else{
if ("静音".equals(phone)) {
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
break;
case TelephonyManager.CALL_STATE_RINGING:
break;
}
}else if ("和谐模式".equals(phone)) {
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
break;
case TelephonyManager.CALL_STATE_RINGING:
try {
Method method = Class.forName(
"android.os.ServiceManager").getMethod(
"getService", String.class);
IBinder binder = (IBinder) method.invoke(null,
new Object[] { TELEPHONY_SERVICE });
ITelephony telephony = ITelephony.Stub
.asInterface(binder);
telephony.endCall();
} catch (Exception e) {
e.printStackTrace();
}
break;
}
}else{
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
break;
case TelephonyManager.CALL_STATE_RINGING:
try {
Method method = Class.forName(
"android.os.ServiceManager").getMethod(
"getService", String.class);
IBinder binder = (IBinder) method.invoke(null,
new Object[] { TELEPHONY_SERVICE });
ITelephony telephony = ITelephony.Stub
.asInterface(binder);
telephony.endCall();
} catch (Exception e) {
e.printStackTrace();
}
listNum = (List<PersonNumber>) dbHelper
.findAllNumber(PersonNumber.TABLENAME);
for (int i = 0; i < listNum.size(); i++) {
if (listNum.get(i).getNumber().equals(number)) {
String time = sdf.format(new Date());
blackNumber = new PhoneBlackNumber(listNum
.get(i).getNumber(), "未知", time);
dbHelper.insertPersonNumber(blackNumber);
Intent intt = new Intent();
intt.setAction(PhoneReceiver.PHONE_RECEIVER_ACTION);
sendBroadcast(intt);
}
}
break;
}
}
}
super.onCallStateChanged(state, number);
}
};
telephone.listen(listener, PhoneStateListener.LISTEN_CALL_STATE);
