在android上获取电话呼叫信息

    private void getCallLogDetail( Context context ) {
        String[] projection = new String[] {
        BaseColumns._ID,
        CallLog.Calls.NUMBER,
        CallLog.Calls.TYPE,
        CallLog.Calls.DURATION
        };
        ContentResolver resolver = context.getContentResolver();
        Cursor cur = resolver.query(
        CallLog.Calls.CONTENT_URI,
        projection,
        null,
        null,
        CallLog.Calls.DEFAULT_SORT_ORDER );
        if( !cur.isAfterLast()) {
        int numberColumn = cur.getColumnIndex( CallLog.Calls.NUMBER );
        int typeColumn = cur.getColumnIndex( CallLog.Calls.TYPE );
        int durationcolumn = cur.getColumnIndex(CallLog.Calls.DURATION);
        String number = cur.getString( numberColumn );
        String type = cur.getString( typeColumn );
        String duration = cur.getString(durationcolumn);
        cur.moveToNext();

        }
