您好我在这个论坛上搜索了很多结果但是找不到。一旦呼叫结束，我需要最后一个拨出电话的详细信息。为此我在这里使用BroadcasteReceiver是我的接收器的代码
public class CallStateBroadcaster extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
((TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE)).listen(new CustomPhoneStateListener(context), PhoneStateListener.LISTEN_CALL_STATE);
}}
以下是PhoneStateListener的代码
public class CustomPhoneStateListener extends PhoneStateListener{
private Context context;
public CustomPhoneStateListener(Context paramContext)
{
this.context = paramContext;
}
@Override
public void onCallStateChanged(int state, String incomingNumber) {
// TODO Auto-generated method stub
super.onCallStateChanged(state, incomingNumber);
((TelephonyManager)this.context.getSystemService("phone")).listen(this, PhoneStateListener.LISTEN_NONE);
if(TelephonyManager.CALL_STATE_IDLE == state)
{
try {
Thread.sleep(1500L);
Intent intent = new Intent(this.context,LastCallInfoActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
this.context.startActivity(intent);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
以下是我的活动的代码，用于获取呼叫记录的呼叫详细信息
public class LastCallInfoActivity extends Activity{
String addtolist;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
Cursor callDetailCursor = getContentResolver().query(CallLog.Calls.CONTENT_URI, null,null,null,android.provider.CallLog.Calls.DATE + " DESC limit 1");
int phoneNumber= callDetailCursor.getColumnIndex(CallLog.Calls.NUMBER);
int callType=callDetailCursor.getColumnIndex(CallLog.Calls.TYPE);
int callDate=callDetailCursor.getColumnIndex(CallLog.Calls.DATE);
int callDuration=callDetailCursor.getColumnIndex(CallLog.Calls.DURATION);
Log.i(">>CAllDetails", "getsCallLogs" );
if(callDetailCursor.getCount()>0)
{
while(callDetailCursor.moveToNext())
{
String phoneNumberString=callDetailCursor.getString(phoneNumber);
String contactName= getContactName(this, phoneNumberString);
String callTypeString =callDetailCursor.getString(callType);
String callDateString=callDetailCursor.getString(callDate);
String callDurationString=callDetailCursor.getString(callDuration);
Date callDayTime=new Date(Long.valueOf(callDateString));
int callCode = Integer.parseInt(callTypeString);
int calldur=Integer.parseInt(callDurationString);
if (callCode==2 && calldur>=1)
{
Double callCost=Double.parseDouble(callDurationString);
String callCostString= String.valueOf( callCost);
Log.i(">>CAllDetails", "getsLocation" );
addtolist= "Name :"+contactName+"\n"+
"Phone Number: "+phoneNumberString+"\n"+"Call Duration :"+
callDurationString+" Seconds\n"+"Call Date: "+callDayTime+"\n"+
callCostString;
}
}
}callDetailCursor.close();
Toast.makeText(this, addtolist, Toast.LENGTH_LONG).show();
}
public String getContactName(Context context, String phoneNumber) {
ContentResolver cr = context.getContentResolver();
Uri uri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phoneNumber));
Cursor cursor = cr.query(uri, new String[]{PhoneLookup.DISPLAY_NAME}, null, null, null);
if (cursor == null) {
return null;
}
String contactName = null;
if(cursor.moveToFirst()) {
contactName = cursor.getString(cursor.getColumnIndex(PhoneLookup.DISPLAY_NAME));
}
if(cursor != null && !cursor.isClosed()) {
cursor.close();
}
return contactName;
}
}
我的这个程序甚至在我的电话断开连接并开始我的活动之前就显示了吐司。请帮助我并更正我的代码，以便在通话结束后执行 谢谢

试试这个添加一个额外的if语句来检查以前的状态是否摘机。
boolean wasoffhook=false;
if(TelephonyManager.CALL_STATE_OFFHOOK == state)
{
wasoffhook=true;
}
if(TelephonyManager.CALL_STATE_IDLE == state&&wasoffhook)
{
try {
Thread.sleep(1500L);
Intent intent = new Intent(this.context,LastCallInfoActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
this.context.startActivity(intent);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

在你的Callstatebroadcaster的onreceive方法中添加这个代码，它会正常工作。我刚解决了。
@Override
public void onReceive(Context context, Intent intent)
{
try
{
if (intent.getAction().equals("android.intent.action.NEW_OUTGOING_CALL"))
{
savedNumber = intent.getExtras().getString("android.intent.extra.PHONE_NUMBER");
Toast.makeText(context,"the no. is"+savedNumber,Toast.LENGTH_LONG).show();
// onOutgoingCallStarted(context,"",callStartTime);
}
else
{
String stateStr = intent.getExtras().getString(TelephonyManager.EXTRA_STATE);
String number = intent.getExtras().getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
int state = 0;
if(stateStr.equals(TelephonyManager.EXTRA_STATE_IDLE)) {
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
Log.d("Testing", "Outgoing call has been disconnect");
intent = new Intent(context, MyCustomDialog.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
context.startActivity(intent);
System.out.println("CAll has been disconnect...............");
// Toast.makeText(this, "CAll has been disconnect", Toast.LENGTH_LONG).show();
break;
}
}
else if(stateStr.equals(TelephonyManager.EXTRA_STATE_OFFHOOK))
{
state = TelephonyManager.CALL_STATE_OFFHOOK;
}
else if(stateStr.equals(TelephonyManager.EXTRA_STATE_RINGING))
{
state = TelephonyManager.CALL_STATE_RINGING;
}
onCallStateChanged(context, state, number);
}
}
catch (Exception e)
{
e.printStackTrace();
}
}
在Callstatechanged方法中添加此代码。
public void onCallStateChanged(Context context, int state, String number)
{
if(lastState == state)
{
//No change, debounce extras
return;
}
switch (state)
{
case TelephonyManager.CALL_STATE_RINGING:
isIncoming = true;
callStartTime = new Date();
savedNumber = number;
// onIncomingCallStarted(context, number, callStartTime);
// onIncomingCallEnded(context, savedNumber, callStartTime, new Date());
// onOutgoingCallEnded(context, savedNumber, callStartTime, new Date());
// wasRinging = true;
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
if (!wasRinging) {
// Start your new activity
onIncomingCallEnded(context,savedNumber,callStartTime,new Date());
onOutgoingCallEnded(context,savedNumber,callStartTime,new Date());
} else {
onIncomingCallStarted(context,savedNumber,callStartTime);
// Cancel your old activity
}
// this should be the last piece of code before the break
break;
case TelephonyManager.CALL_STATE_IDLE:
if(isIncoming)
{
onIncomingCallEnded(context, savedNumber, callStartTime, new Date());
}
}
lastState = state;
}
这样可行。
