通话结束后从通话记录中删除通话
我是Android开发的新手。我想拨打电话,但不想将号码存储在我的通话记录中。通话结束后如何从通话记录中删除该号码?
回答:
我无论如何都使用4.2.2,我不得不修改aftab的代码,因为它对我不起作用。给出我想做的事情可能是一个麻烦的问题,即在传入呼叫结束后立即更新呼叫日志。我认为我必须给操作系统足够的时间来更新表,然后再删除条目,否则它将不存在:
private void deleteNumber(String phoneNumber) { try {
Thread.sleep(4000);
String strNumberOne[] = { phoneNumber };
Cursor cursor = context.getContentResolver().query(
CallLog.Calls.CONTENT_URI, null,
CallLog.Calls.NUMBER + " = ? ", strNumberOne, "");
boolean bol = cursor.moveToFirst();
if (bol) {
do {
int idOfRowToDelete = cursor.getInt(cursor
.getColumnIndex(CallLog.Calls._ID));
context.getContentResolver().delete(
CallLog.Calls.CONTENT_URI,
CallLog.Calls._ID + "= ? ",
new String[] { String.valueOf(idOfRowToDelete) });
} while (cursor.moveToNext());
}
} catch (Exception ex) {
Log.v("deleteNumber",
"Exception, unable to remove # from call log: "
+ ex.toString());
}
}
并调用我在另一个线程上运行的函数(因为我正在睡觉):
new Thread() { public void run() {
deleteNumber(incomingNumber);
}
}.start();
添加睡眠后,在通话结束后立即尝试删除时,似乎可以使用。
更新:意识到最后一条评论之后,我们可以在android提供程序调用日志uri上设置contentobserver:
public class BlockerContentObserver extends ContentObserver{private Context context;
private String phoneNumber;
public void setPhoneNumber(String phoneNumber) {
this.phoneNumber = phoneNumber;
}
public BlockerContentObserver(Handler handler,Context context) {
super(handler);
this.context=context;
}
@Override
public boolean deliverSelfNotifications() {
return true;
}
@Override
public void onChange(boolean selfChange) {
// TODO Auto-generated method stub
super.onChange(selfChange);
Log.v(Consts.TAG,"has call log changed:"+selfChange);
deleteNumber(phoneNumber);
}
private void deleteNumber(String phoneNumber) {
try {
String strNumberOne[] = { phoneNumber };
Cursor cursor = context.getContentResolver().query(
CallLog.Calls.CONTENT_URI, null,
CallLog.Calls.NUMBER + " = ? ", strNumberOne, "");
boolean bol = cursor.moveToFirst();
if (bol) {
do {
int idOfRowToDelete = cursor.getInt(cursor
.getColumnIndex(CallLog.Calls._ID));
context.getContentResolver().delete(
CallLog.Calls.CONTENT_URI,
CallLog.Calls._ID + "= ? ",
new String[] { String.valueOf(idOfRowToDelete) });
} while (cursor.moveToNext());
}
} catch (Exception ex) {
Log.v(Consts.TAG,
"Exception, unable to remove # from call log: "
+ ex.toString());
}
}
}
现在,我们使用以下方法注册以监听呼叫日志数据库中的更改:
mContentObserver = new BlockerContentObserver(new Handler(),context);
然后我们创建一个方法来注册事件或取消注册:
/*handles the registration of our content observer used for monitoring the call log*/private void RegisterContentObserver(boolean shouldRegister){
if(shouldRegister)
{
context.getContentResolver().registerContentObserver(
android.provider.CallLog.Calls.CONTENT_URI,
true,
mContentObserver);
}
else {
try {
context.getContentResolver().unregisterContentObserver(mContentObserver);
} catch (IllegalStateException ise) {
// Do Nothing. Observer has already been unregistered.
}
}
}
